Robot vacuums are one area in which the 21st century has somewhat aligned with "Jetsons"-style predictions. In the last few years, they have become widely available at a variety of price points, from budget models to feature-packed robots that avoid obstacles, mop your floors and empty their own dustbins.
Not only can the best robot vacuums turn this common household chore into something easy and convenient, but they also free up your time, so you can relax. You can schedule automatic cleanings or ask your smart speaker or smartphone to start your vacuum while you're on the couch or on vacation.
The BestReviews Testing Lab tested more than 30 robot vacuums. We evaluated them on performance, ease of use, smart capabilities and build quality. We ran tests on carpet and hardwood flooring, checked their ability to move from one surface to the other and examined their overall navigation. We paid special attention to how well they sucked up pet hair and cat litter. Finally, we assessed how easy they were to clean and maintain.
Many popular brands have introduced extensive robot vacuum lines that vary in price, feature set and performance. Additionally, for every top-selling model, there can be five or more low-cost clones. After putting all these machines to the test, we think the Roomba line from iRobot is still the best in the category, including our top two picks, the impressive Roomba s9+ and the value-packed Roomba i4.
Our top picks: Which robot vacuum is best?
Best Robot Vacuum Overall
Battery life: 107 min | Dimensions: 12.25” L x 12.25" W x 3.5” H | Dustbin capacity: 0.5 L | Weight: 8.15 lb | Mapping: Yes | Self-emptying: Yes | Voice commands: Alexa, Google Assistant, Siri Shortcuts | Scheduling: Yes
The pricey but powerful Roomba s9+, with its self-emptying base, is our top pick among robot vacuums. It aced our dirt and flooring tests, vacuuming up spilled salt, breakfast cereal, pet hair and cat litter with ease.
Its wide multisurface rubber brushes effectively covered almost a foot of the floor with each pass and went from carpet to hardwood to rugs and back without mishap. When it comes to cleaning corners, the s9+’s D-shaped design beat other robot vacuums we tested, getting into the nooks and crannies and leaving very little behind.
A model from 2019, the Roomba s9+ features smart mapping, allowing you to specify rooms and areas to clean and making the robot’s already-efficient navigation even more direct.
Its battery lasted 1 hour and 47 minutes on a full charge, cleaning 140 square feet in 37 minutes. In testing, it filled its bin in 28 minutes and automatically returned to its self-emptying charge base. The bin-emptying process is about as loud as the s9+ gets, resembling a standard vacuum cleaner, but it’s notably quiet during actual cleaning.
With the intuitive and helpful iRobot Home app, the s9+ can be scheduled to run at specific times, and because it also supports Alexa, Google Assistant and Siri Shortcuts, you can command it with your voice. You can also create "keep out zones" which is exactly what it sounds like — areas you don't want the robot to go like by your pet's water bowl or under the entertainment stand where you may have tons of cords.
With impressive suction on both carpeted and bare floors, outstanding corner-cleaning capability, excellent navigation and a self-emptying base, the Roomba s9+ earned a perfect 5 out of 5 score in our ratings. We think it’s simply the best robot vacuum you can buy.

Battery life: 94 min | Dimensions: 13.34” L x 13.26” W x 3.63” H | Dustbin capacity: 0.3 L | Weight: 7.44 lb | Mapping: Yes| Self-emptying: No | Voice commands: Alexa, Google Assistant, Siri Shortcuts | Scheduling: Yes
The iRobot Roomba i4 is a great robot vacuum for anyone on a budget or looking to clean a smaller home or apartment. We found that it did a fantastic job with coffee grounds and cereal on both carpet and bare floor.
It also did well in pet hair and cat litter tests. Its rubber multisurface rollers not only resisted getting tangled with pet hair, but also made it effective on a variety of surfaces, from low-pile carpet to hardwood to vinyl plank.
It ran for 94 minutes before returning to its home base to recharge, and cleaned an area of 346 square feet in 71 minutes, taking two hours to recharge a depleted battery to full. With its row-by-row navigation, it covered a lot of ground efficiently and faster than competing budget-friendly vacuums.
Transitions between surfaces didn’t faze the i4, even though it took a brief moment to figure out the best way to get onto a high-pile rug from carpet. Its side brush let it clean corners with only a little residue left behind, and it managed to clean under dining chairs and along couches faster than Roomba’s budget models.
It features a complementary smartphone app that lets you view maps of your floor plan so you can tell your robot to clean (or avoid) specific rooms or areas of your home. It also works with Alexa, Google Assistant and Siri Shortcuts for voice-controlled jobs.
While it lacks some of the power and advanced features of more premium models, we found the Roomba i4 a helpful addition to a daily cleaning routine and a worthwhile purchase to keep your home spic and span.

China-based roborock, backed by Xiaomi, is known for some of the most advanced, and most expensive, robot vacuums on the market. So a model like the roborock Q5 Max+ Robot Vacuum is a real bargain, considering its impressive features and self-emptying dock.
Unike single-roller models, the Q5 Max+ offers a dual-roller design, once found only on competitors, which helps increase the mechanical pickup of dirt and debris. It also packs 5,500 Pa of suction force, which is a respectably strong value for a robot vacuum. And its 5,200 mAh battery can run for 240 minutes, or four hours, before needing to recharge.
The Q5 Max+ maps with LiDAR, so it avoids the bumping and confusion of simpler robot vacs and can also pick the most efficient route for cleaning. Its big 770-milliliter dustbin can go for days before filling up.
An advanced app lets you see 3D maps and supports up to four separate floors or levels, plus suggests no-go zones. It supports Alexa, Siri and Google Home integration.
Best for Small Spaces
Battery life: 100 min | Dimensions: 12.79" L x 12.79" W x 2.85" H | Dustbin capacity: 600 mL | Weight: 6.35 lb | Mapping: No | Self-emptying: No | Voice commands: None | Scheduling: Yes
One of the smallest, slimmest, lightest and easiest robot vacuums to use, the Eufy BoostQ RoboVac 11S MAX ditches things like advanced navigation and self-emptying docks for straightforward operation and an appealing price.
The RoboVac 11S Max is less than 3 inches tall, shorter than most other robot vacuums. This lets it slip under couches, beds and other low-slung furniture where rival models can’t.
Unlike some eufy RoboVacs, it comes with a brush roller for picking up dirt and hair, and a cleaning tool to get hair out. A wide, stiff side brush draws debris into its cleaning path. Its BoostIQ feature automatically increases suction force when it moves from hard flooring to low carpet.
The 11S Max doesn’t use mapping or an app. Instead, it comes with a simple, battery-operated remote control. You can schedule, steer and turn the 11S Max on and off with its remote, making it easy to learn for people who may be uncomfortable with smartphone apps.
Feature-Packed
Battery life: 120 min | Dimensions: 12.9” L x 12.5” W x 3.5” H | Dustbin capacity: 1,000 mL | Weight: 14.5 lb | Mapping: Yes | Self-emptying: Yes | Voice commands: Alexa, Google | Scheduling: Yes
You can always trust a Shark vacuum on features, and the Shark AI Ultra is a perfect example. This smart mapping robot vacuum comes with a self-emptying base and thorough multi-pass cleaning.
We tested a previous generation of the Shark AI Ultra, and were impressed by its mapping and navigation features. It uses LiDAR to precisely make its way around your home and avoid objects it finds in its path, so there’s less bumping or running over things while cleaning. Its single brushroll is self-cleaning and did well in our pet-hair tests on both carpet and hard flooring.
The Shark AI Ultra offers Matrix cleaning in sequential rows in one direction, then again in a perpendicular direction, creating a crosshatch pattern that’s more thorough than single-pass or random cleaning of other robot vacuums. Its self-empty dock can hold up to 60 days' worth of dirt, and its app supports Alexa and Google Home integration.
Best for Cleaning Up Hair
Battery life: 120 min | Dimensions: 13” L x 12.8” W x 4” H | Dustbin capacity: 260 mL | Weight: 14.17 lb | Mapping: Yes | Self-emptying: Yes | Voice commands: Alexa, Google | Scheduling: Yes
There are several ways to get hair out of robot vacuum brushes. Many models use rubberized fins that keep long hairs loose and easily removable. Others come with cleaning tools to help get tangled hair out of bristles. However, the eufy L60’s solution is probably the most satisfying: It cuts the hair with its dock.
On the underside of the L60’s self-empty dock is a sharp cutting blade that, as the robot empties, slides up and down the length of the brush roller at just the right distance to slice through tangled hair, which then is neatly sucked up into the dock’s dustbin. If lifted or depowered, the blade goes quiet, saving hands and fingers. It’s the most direct solution we’ve yet seen for this perennial challenge.
The eufy L60 offers laser-based mapping to navigate around your home and syncs with a smartphone app. It offers four suction levels up to 5,000 Pa of power, which is a good number for a robot vac. The dock holds up to 60 days' worth of dirt and cut-up hair.
Most Comprehensive
Battery life: 180 min | Dimensions: 13.9” L x 13.78” W x 3.8” H | Dustbin capacity: 330 mL | Weight: 26 lb | Mapping: Yes | Self-emptying: Yes | Voice commands: Alexa, Siri, Google | Scheduling: Yes
The Roborock Qrevo Pro is a combo vacuum and mop robot with a self-empty dock. We tested an earlier generation of the Qrevo and found that its spinning mop disks provided some of the most effective robot mopping we’d encountered.
The Qrevo Pro packs 7,000 Pa of suction power. It uses LiDAR scanning to map and navigate your home, with real-time object avoidance so you don’t necessarily have to pick up shoes or toys.
Its two mop disks not only spin to get grime off of hard floors but also extend outward for up-close cleaning of corners and edges. They lift 10 millimeters to avoid getting rugs wet during a cleaning session and are washed and dried with heat to stay sanitary.
The Qrevo Pro has a big dock that not only stores dirt but also clean and dirty water for the mop. It can spot clean, auto-sense dirt and surface types, and automatically empty and refill both its dustbin and its water tank.
Versatile Choice
Battery life: 220 min | Dimensions: 13.78” L x 13.78” W x 3.8” H | Dustbin capacity: 350 ml | Weight: 9.3 lb | Mapping: Yes | Self-emptying: Yes | Voice commands: Alexa, Siri, Google | Scheduling: Yes
The dreame L10S Pro is almost the same as the Roborock Qrevo Pro. It uses rotary mopping discs that extend to clean edges, uses LiDAR to map and avoid obstacles, and cleans and dries its mops with heat.
The L10S Pro offers 7,000 Pa of suction when vacuuming. Its built-in 350-milliliter bin self-empties into its multifunction dock that can store up to 75 days' worth of dirt. It has fast LiDAR mapping with active object avoidance, sensing sneakers, socks and toys and navigating around them.
Its dual rotating mops help get at stubborn grime on hard surfaces and can extend outward when close to a wall or corner to get into narrow spaces. The dock washes and dries the mops automatically in heated water and air, and auto-fills both the water tank and the cleaning solution when needed.
Simple Yet Solid
Battery life: 110 min | Dimensions: 13.5” L x 13.5” W x 4” H | Dustbin capacity: 230 mL | Weight: 9.7 lb | Mapping: Yes | Self-emptying: Yes | Voice commands: Alexa, Google | Scheduling: Yes
The Shark Matrix Plus 2-in-1 is a combination vacuum and mop robot that won’t break the bank. Like other Shark robot vacuums, it uses a Matrix grid to clean in two perpendicular rows, digging deeper than competitors.
The Matrix Plus 2-in-1 uses a swappable combo mop and tank bin that you swap with a regular dustbin when you want to use the mopping function. The mop pad vibrates as the robot runs to gently scrub hard flooring.
The Matrix Plus uses LiDAR to map your home and navigate around obstacles, and it can be sent to spot-clean if needed. It also has a nifty Shark feature that uses directed air to blow debris out of corners while it works.
The Matrix Plus 2-in-1 is one of the more affordable models that comes with a self-empty dock. This dock holds around 60 days' worth of dirt. All in all, it’s a great deal for a combo robot mop and vacuum with a dock.
Powerful Performance
Battery life: 180 min | Dimensions: 13.9” L x 13.78” W x 4.05” H | Dustbin capacity: 260 mL | Weight: 10 lb | Mapping: Yes | Self-emptying: Yes | Voice commands: Rocky, Alexa, Siri, Google | Scheduling: Yes
The Roborock S8 MaxV Ultra is the most powerful and most feature-packed of all the robot models in our list. It offers outstanding vacuum power, comprehensive mopping, direct navigation and self-emptying. It also can take pictures of your pets.
The S8 MaxV Ultra boasts 10,000 Pa of suction power, matching many handheld and stick vacuums, with dual rollers for superior mechanical agitation and pickup. Its side brush extends out to clean along walls and in corners. And its mop lifts up to 20 millimeters to avoid carpet while traveling.
Its smart camera plus LiDAR navigation maps quickly and knows to recognize pet waste and mirrors. We tested an earlier model of the S8 and confirmed that its navigation and mapping are well above par.
The S8 MaxV Ultra comes with a formidable multifunction dock that holds up to 49 days' worth of dirt. It also contains clean- and waste-water tanks for filling and cleaning the mop function.
Perhaps the most surprising, or fun, feature of the S8 MaxV Ultra is its built-in camera and speaker. This allows you to check in on your home, take photos of your pets or even say hi to them, all from the robot vacuum and the Roborock app. It also has its own voice assistant, Rocky, built in.
iRobot Roomba 694
Battery life: 75 min | Dimensions: 13.4” L x 13.4” W x 3.54” H | Dustbin capacity: 0.35 L | Weight: 6.77 lb | Mapping: No | Self-emptying: No | Voice commands: Alexa, Google Assistant, Siri Shortcuts | Scheduling: Yes
The iRobot Roomba 694 is a simple yet solid robot vacuum that uses a basic semi-random navigation method to clean your home.
Unlike a row-by-row or smart mapping robot, the 694 is a bump-and-clean model. This means it moves forward until it bumps into an obstacle, turns in a semi-random direction and goes on from there until it bumps into something else, at which point it chooses the next semi-random direction to turn. This can look aggravating to an observer, but if used regularly, it ends up cleaning almost as much of a given area as more advanced navigation systems.
The Roomba 694 ran for 75 minutes during testing before needing to return to its dock to recharge for two hours. It cleaned 250 square feet in 56 minutes before announcing it had completed the job to its satisfaction. After 75 minutes, its bin needed emptying, which was a simple job of removing it from the chassis and emptying the contents into a waste basket.
Although the Roomba 694, lacks mapping and uses semi-random navigation, it supports Wi-Fi and Bluetooth connections and can be controlled by Alexa, Google Assistant or Siri Shortcuts. It was effective in vacuuming coffee grounds, cereal, pet hair and pet litter from both carpet and bare flooring. However, its side brush often sent stray bits of larger debris across the floor.
It moved from surface to surface with no trouble except for high-pile carpeting, and its roller brush needed occasional cleaning from tangled pet hair.
Despite some drawbacks, the Roomba 694’s simplicity and overall effectiveness make it a great budget model to consider.

Best Robot Vacuum and Mop Combo
Battery life: 128 min | Dimensions: 13.3" L x 13.3” W x 3.4” H | Dustbin capacity: 0.4 L | Weight: 7.35 lb | Mapping: Yes | Self-emptying: Yes | Voice commands: Alexa, Google Assistant, Siri Shortcuts | Scheduling: Yes
The Roomba j7+ Combo robot mop and vacuum is as close to hands-off cleaning as we achieved in our testing. It combines a powerful robot vacuum and a robot mop into a single device and comes with a self-emptying dock to boot. With its retractable mopping pad, it can go from vacuuming carpet to mopping hardwood on the same cleaning run.
To best use both the Roomba j7+ Combo’s functions, we recommend doing a full mapping run prior to cleaning. In our tests, the j7+ Combo took 54 minutes to map five rooms on the same floor, noting which areas were carpeted and which were hardwood or laminate.
During cleaning, the j7+ ran for 128 minutes on a single charge, the longest of any of the models we tested. It'll tackle 350 square feet in about an hour, returning to the base to empty its bin roughly 70 minutes after cleaning. It moved from carpet to bare floor without a hitch and performed well in particle and spill testing, although it needed a few extra passes to fully clean some cat litter and cereal.
Like its non-mopping siblings in the Roomba “j” series, it did very well with pet hair, removing a visible amount without any getting tangled in its twin rollers. When it came to mopping, it removed a stuck-on stain on the hardwood with ease, and it left no residue after mopping up spills.
With keep-out areas, zone cleaning and smart-assistant compatibility, the Roomba j7+ Combo is an all-in-one cleaning machine that earns a rating of 4 out of 5 from our testing.

How we tested
Setup
- Unboxing: We noted each robot vacuum’s packaging, how secure it was, how complete its accessories were and if it used too much plastic or too little protection.
- Setup: We kept track of the setup process for each robot vacuum, from physically plugging in its dock to any assembly or preparation that needed to be done on the unit.
- App: We downloaded and installed any apps recommended or required to use the unit, noting user interface, comprehensiveness and ease of use.
Performance
- Carpet: We tested each robot vacuum extensively on carpet, both in area cleaning and in spot cleaning with small, medium and large particulates, in open areas, in corners and near or beneath furniture.
- Hardwood: We tested the same particulates on hardwood and similar bare flooring, paying attention to corners and edges.
- Transitions: We tested the performance of each robot vacuum in negotiating transitions between surface types, such as carpet to hardwood, carpet to rug, hardwood to rug and so on.
- Navigation: We observed each robot’s navigation capabilities, its cornering, its ability to maneuver around obstacles or in tight spaces, its coverage efficiency and its ability to return to its home dock.
- Pets: For pet lovers and pet homes, we tested each robot vacuum’s ability to remove pet hair from carpet and bare flooring, how effective it was at cleaning up spilled litter, how often pet hair got tangled in its rollers and how easy it was to remove.
Ease of use
- Mapping: For models with mapping, we tracked the duration and area of a mapping run, the accuracy of the resulting maps and the usefulness of the maps when specifying a room or zone to clean.
- Scheduling: We checked if a robot vacuum offered scheduled cleaning, how easy a schedule was to set and if the robot vacuum followed the schedule accurately.
- Voice control: We set up each vacuum that supported voice assistants with Alexa or Siri Shortcuts to see how effectively and precisely they could be controlled by voice.
Maintenance
- Emptying: It was important for us to check how easy or difficult it was to empty each robot vacuum’s dirt bin, both those with a manual bin and those with a self-cleaning or self-emptying dock. We also noted how long it took to fill a bin or dock and how often you needed to empty it.
- Upkeep: We cleaned each robot vacuum after testing, paying attention to its roller brushes and filters, but also checking and cleaning its wheels, sensors and any side brushes. We also observed how dirty a robot got during cleaning and how easy it was to clean its surfaces.
Why buy a robot vacuum?
Consider investing in a robotic vacuum cleaner if any of the following apply.
- You love coming home to a clean space, but you hate vacuuming.
- You enjoy living in an environment with spotless floors.
- You find you can’t keep up with the ever-accumulating pet hair or other debris in your home.
- You want to minimize the amount of time you spend cleaning your home.
- You’re interested in high-tech gadgets and would get great enjoyment from a robotic vacuum cleaner.
- You’re looking for ways to simplify your life.
What to consider before you buy
Here are a few questions to answer before deciding whether to purchase a vacuum.
Is it able to navigate the rooms of my home?
Many mid-range to high-end robotic vacuum cleaners use mapping technology to navigate specific rooms, like the Roomba s9+ and i4 or the Eufy RoboVac X8. Not all robotic vacuums can do this, though. If you have a house with a complex floor plan, consider a device with more advanced artificial intelligence.
Can the robot vacuum cleaner self-correct if I’m not home?
If you want a cleaner that works while you're away, make sure you choose one with good navigation and object-sensing capabilities. The Eufy RoboVac X8, for example, uses laser navigation to find and redirect from obstacles almost in real time, while the Roomba i4 can disentangle itself from cords by means of built-in maneuvering.
What is the vacuum cleaner's level of hazard avoidance?
All robot vacuums have sensors, often called cliff sensors, that stop them from plunging down a stairwell or landing.. Some robotic vacuums also support “virtual walls” so you can block off certain areas of your home (“no-go zones”). Both the Shark IQ and the iRobot Roomba j7+, for example, let you set up digital barriers and virtual walls around fragile objects, pet bowls and cluttered closets, to maximize efficiency and minimize obstacles.
What about battery life?
Robotic vacuums have lithium-ion rechargeable batteries, but the runtime varies from one product to another. This, in turn, affects the length of your cleaning sessions.
Your machine will need to spend time on the charging dock in between cleaning sessions. But you probably don’t want to pause cleaning just to put it on the charging dock. Most of the models we tested, including the budget-priced Roomba 694, can sense when their batteries are running low and suspend a cleaning job to return to their dock as quickly as possible. Once they’ve topped off their batteries, they resume the same job where they left off. A full charge, however, takes an average of two to two and a half hours.
Since larger homes require longer battery life, take stock of the square footage recommendation and the battery runtime of the vacuum you’re interested in. A runtime of an hour and a half is the average minimum among models we recommend, although that can change depending not only on square footage but also how much dirt the robot vacuum finds and how complex the navigation is.
What type of flooring and debris are you dealing with?
Some robotic vacuums are better able to handle different types of dirt and debris. A thick-pile carpet requires a gentler brush and a more powerful motor than a hard floor or a low-pile carpet. Homes with large amounts of pet hair also need that power. Eufy’s RoboVac X8 has the most powerful suction among our recommended vacuums, but the roller brushes of the Roomba i4 and Shark IQ also do a good job on high pile.
If you’re a pet owner, pick a model that can handle the fur your pets shed. Choosing a device with a high-efficiency particulate air (HEPA) filter or similar pleated-type filter, such as the filter in the Eufy RoboVac S11 Max, helps keep allergens at a minimum in your home. Also, if you have lots of hardwood flooring, verify that the vacuum you’re considering is suitable for it. All our top picks do well on hardwood and other hard flooring types, but a gentler rubber roller, as on the Roomba s9+, may be more suitable to preserve real hardwood finishes.
Do you want a robot vacuum with smart capabilities?
Even if you don’t live in a completely “smart home,” the ability to control your robotic vacuum cleaner with an app or voice assistant is helpful. Here are a few things it can offer.
Useful information: A good robot vacuum app not only allows you to send the robot on a cleaning job but also keeps track of error messages, job duration, area covered, extra dirt discovered, battery life and more.
A regular cleaning schedule: Some of these vacuums allow for the automatic creation of a cleaning schedule. The iRobot app used by Roombas, for example, learns your cleaning routine and, after a few uses, offers suggestions for schedules that reflect seasonal changes such as pollen or spring cleaning. Scheduling cleaning jobs also lets you run a robot vacuum while you’re away, so you return to a freshly vacuumed home.
Voice control: Most robot vacuums with app control also offer compatibility with voice commands and digital assistants, most often Alexa and Google Assistant. This lets you control your robot vacuum with a simple command, such as, “RoboVac X8, clean the dining room” or “Clean the kitchen at 10 p.m.” iRobot’s Roombas also offer compatibility with Apple’s Siri assistant via the Shortcuts app.
How to clean a robot vacuum
A robot vacuum needs regular cleaning to stay in peak condition. If you don’t have a self-emptying model, empty its dustbin after every full job for the best results. Every week or so, check its rollers for pet hair and other tangles and clean its sensors and wheels.
For most robot vacuums, this involves simply turning the robot on its back and opening an access panel to its roller brushes. If possible, remove the roller brush or brushes and cut or untangle string, pet hair and other debris. Clean the compartment containing the rollers as well. Replace the rollers when you’re done.
Use a soft microfiber or lint-free cloth to clean any sensor windows on your robot vacuum, including cliff sensors, IR receivers, camera windows and laser ports. Check the wheels and axles for debris.
Every so often, unscrew the side brushes if possible and check for debris in the axle. If possible, rinse the dirt bin in warm water, and replace the dust filter when recommended.
Robot vacuum cleaner prices
Robot vacuums cost more compared to a standard upright vacuum. That said, the prices of vacuums can vary. Generally, the higher the price, the more features you have and the more cleaning power you’ll get.
Under $200
The most affordable robots cost under $200. You will not find many iRobot Roombas in this price range, but you are likely to find some Eufy RoboVacs, Shark robots, and ILIFE robots in this mix, not to mention dozens of capable knockoffs from fly-by-night brands that do reasonably well for a while and then conk out for no particular reason.
Less-expensive robotic vacuum cleaners feature more basic cleaning options (think low-pile carpet, minimal messes and smaller living rooms) and may lack some of the scheduling features seen in costlier models.
From $200 to $500
Between $200 and $500, you’ll find the best entry-level and mid-priced models of well-known and dependable robot vacuum manufacturers, including iRobot, Roborock, Eufy and Shark. Pricier robotic vacuum cleaners tend to have better smart mapping abilities. If you want something that responds to voice commands, offers powerful suction and stands out for its navigation system and battery life, look in this price range.
From $500 to $1,000
What would you get for a $1,000 vacuum cleaner like our top pick, the iRobot Roomba s9+? A refined cleaning experience on all fronts, mostly from better corner and edge performance, wider brushes, more powerful suction, scheduling and zone options, and self-cleaning docks. You may balk at spending this much on a vacuum cleaner, but the savings in time and effort are worth it.
Potential cons of robot vacuum cleaners
Though highly convenient and useful, there are some potential downsides to robotic vacuums that you should be aware of before you buy one.
Price
Robotic vacuum cleaners are generally much more expensive than upright vacuum cleaners. Even a budget robot vacuum can cost as much or more than a high-end upright vacuum cleaner. The budget-priced basic Roomba 694, for instance, costs about $50 more than the Shark Navigator Lift-Away Deluxe Upright Vacuum, which is our top choice for the best upright vacuum.
The price difference is due, in large part, to convenience: You don’t have to run the vacuum yourself.
It also has to do with the advanced features offered, such as Wi-Fi connectivity, smart mapping and compatibility with a voice assistant.
Jams
Robotic vacuum cleaners can get stuck. Even the smartest models aren’t as smart as you are, and they can jam under couches or get confused in a cluttered room, bringing a cleaning session to a halt.
In other words, you could come home to an unvacuumed living room and a jammed robot vac that needs some “help” extricating itself from a tight situation.
Less power
Though more powerful than a cordless stick vacuum, robotic vacuum cleaners lack the powerful suction of a traditional upright. You simply can’t get a super deep clean with a robotic vacuum.
We recommend using it often in combination with a traditional vacuum for heavily soiled areas or on dense surfaces like high-pile carpet and even medium-pile carpet.
Maintenance
Robot dustbins require more frequent emptying than upright vacuum dustbins. This is because they simply aren’t very big. That said, emptying the dustbin of a robotic vacuum cleaner is fairly simple — you just need to do so regularly.
Tips
- Declutter before you vacuum. Most robotic vacuums can get out of tight spots thanks to their intelligent sensors. To make sure yours doesn't get trapped under the living room couch or in another tight spot, clear obstacles as much as you can beforehand.
- Place it on the charging dock first. It’s a good idea to fully charge your new robotic vacuum before you put it to work on your floors.
- Read the manual carefully. Although it’s a lot to take in at once, you will appreciate being able to put all the features of your robotic vacuum to use right away.
- Change the filter often. This helps keep allergens to a minimum inside your home.
FAQ
Q. What’s the advantage of a robot vacuum cleaner over an upright vacuum?
A. The biggest advantage is that you can set it and forget it. These devices also tend to take up a lot less space, so they’re great for smaller homes.
Q. Can a robot vacuum cleaner find its way under furniture to clean those spaces?
A. It depends on whether the vacuum you choose can clear said furniture. If your couch is high enough off the ground, a robotic vacuum should have no problem getting beneath it to clean. Eufy’s slim RoboVacs, such as the 11s Slim and 11s Max, are intended to fit where other robot vacuums can’t go. However, if a robot vacuum thinks it can fit under a piece of furniture, but actually can’t, it might keep trying until it’s wedged in tight and has to call for help. This can happen when low-profile furniture is on high-pile carpet.
Q. Can a robot vacuum do spot cleaning in smaller areas?
A. Many robot vacuums offer spot cleaning, including most of our top picks. iRobot Roomba models and Eufy RoboVacs, for example, have specific spot-clean modes that can be activated from the unit itself or from a remote or app. To use spot clean, it’s recommended you physically place the robot on the mess to be cleaned. It will then run a cleaning pattern focused on the area without continuing on to a different part of the room.
