Shopping for a robot mop can be a daunting task. There are a lot of brands and a lot of options. The BestReviews Testing Lab decided to revisit a head-to-head matchup, comparing eufy to Roomba, that we first did in 2024. This time, we pitted eufy’s latest Omni-series robot mops against a current model from iRobot’s famed Roomba lineup.
When we last did this comparison, iRobot was still riding high and eufy was playing catch-up. Those days are long gone. Our testing found that eufy’s robot vacuums now compete feature-for-feature with robot vacuum brands across the market, while Roombas, for the most part, have stagnated.

The BestReviews Testing Lab strives to investigate every claim the brand/manufacturer makes about the product. For this article, we tested these robot vacuums in a 1,000-square-foot, two-level apartment with a mix of vinyl plank hard flooring, medium-pile carpeting and short-pile area rugs.
Overall, the eufy Omni models we tested were effective cleaners and a pleasure to use, even if their features could sometimes get in the way of their usefulness. On the other hand, the Roomba Plus 405 was disappointing and underpowered except during deep cleaning.
Any robot vacuum from a trustworthy brand makes it easier to keep a home clean. They can handle regular pickup of dust and small particles from most floor surfaces and can mop up everyday splatters and footprints.
Eufy is the home-products brand of Anker, the company also known for its power banks and adapters, as well as Soundcore headphones and speakers.
With the first Roomba in 2002, iRobot invented the consumer robot vacuum. Every robot vacuum since has owed its basic concept to that first Roomba model.

Despite their convenience, robot vacuums are not better than upright or canister vacuums, or manual mops. Eufy and iRobot both have drawbacks that we noted during testing and research.
Products by eufy are not known for repairability or longevity. Sometimes, their features are better in concept than execution.
For a pioneering, original brand, iRobot has lost a lot of its innovation and feature parity with rivals.
In this round of our robot vacuum tests, we compared the eufy Omni E25 and E28 robot vacuums with the iRobot Roomba Plus 405. All three models are combination mopping and vacuuming robots with self-emptying, self-washing docks.
Dimensions: 12.83” L x 13.72” W x 4.4” H | Dock dimensions: 14.55” W × 18.18” D × 17.19” H | Runtime: 125 min | Mopping: Roller | Navigation: LiDAR, camera
The eufy Omni E25 was our favorite among the robot vacuums we tested in this round, providing the best all-around cleaning, mopping and automation. It removed over 95% of large debris and over 90% of fine particles in our tests, although it struggled somewhat with fine powder on hard flooring and faux fur on short pile. It mopped up small spills well, although dried stains took multiple passes before being removed. The E25 has excellent object recognition, identifying and labeling shoes, power cords and fabric, keeping its map updated, and avoiding us if we stepped in its path. The Omni dock was relatively quiet for a self-empty dock and doesn’t take up as much space as some rival all-in-one docks.
Dimensions: 12.83” L × 13.72” W × 4.4” H | Dock dimensions: 14.63” W × 19.07” D × 17.29” H | Runtime: 125 min | Mopping: Roller | Navigation: LiDAR, camera
The eufy Omni E28 robot vacuum and mop is essentially identical to the E25. Its main difference is its Omni dock, which, in the E28’s case, integrates a lift-away portable stain remover that takes up the entire upper half of the dock. It integrates the clean and dirty water tanks plus the power cord and power supply, so when it’s removed, the dock doesn’t function and the E28 robot doesn’t charge. As a spot cleaner and stain remover, it performed adequately but unspectacularly, and required a separate stain-removal spray to get at stubborn dirt. It’s also loud, registering over 85 decibels during operation, the same noise it makes when emptying the robot’s dustbin.
Dimensions: 14.1" L x 13.8" W x 4.2" H | Dock dimensions: 17.72” L x 12.4” W x 18.58” H | Runtime: 120 min | Mopping: Rotary pads | Navigation: LiDAR
The iRobot Roomba Plus 405 combo vacuum and mopping robot is a midrange cleaning robot with an auto-empty, mop-washing dock. It disappointed in our tests, leaving behind up to 50% of various debris in our vacuuming tests, unable to move any faux fur on short-pile rugs, and spreading spills around with its mopping pads. It did, however, remove all the faux fur on hard flooring, and in deep-clean mode used a back-and-forth scrubbing motion to improve its overall cleaning performance. Its dock is somewhat loud, but does the job, while its app buried controls in unintuitive sections and lost synchronization with the robot long enough to need a reboot.
The Roomba Plus 405 is the lowest-priced of the three robots tested, retailing at $799. By comparison, the eufy Omni E25 starts at $1,299, while the Omni E28 is priced at $1,399. The Roomba 405 is a lower midrange model, while the two eufy robots are considered premium machines. Both iRobot and eufy discount their models often, cutting prices sometimes 40% to 50%.
There was a time when iRobot’s Roombas were the most reliable robot vacuums around. They were easy to maintain and repair, while eufy robot vacuums were cheap and derivative. But iRobot dropped the ball, forgot innovation and switched its lineup to mediocre performers like the Roomba Plus 405. Though the eufy Omni E25 and E28 are not the best cleaning robots we’ve ever seen, they are superior to the Roomba for everyday cleaning.
