- Suction
- iRobot claims 70x
- Navigation
- ClearView LiDAR
- Mopping
- Reusable microfiber pad
A space saving Roomba with no tall dock, good LiDAR navigation and a large compacting bin. TechRadar needed to empty it after 8 days rather than 60 and measured 78 dB. Mopping and obstacle handling are weak, so it suits small tidy homes.

A capable 2026 Roomba with LiDAR, a roller mop and a hot wash dock that needs attention only about every 90 days, and at $799.99 it now sits in the midrange. Reviewers split: Gizmodo and Xataka liked its vacuuming and mopping, while Tom's Guide found it loud, prone to scattering debris and leaving mop residue. Skip it if you need it to fit under low furniture or want the quietest robot.

What reviewers found
iRobot Roomba 205 DustCompactor Combo
- TechRadar (Performance 2.5/5): Measured an average of 78 dB from five feet. The roughly 1.5 L bin needed emptying after eight days. It pushed aside toys and dragged a phone cable. Called a crushing disappointment. Source
- Tech Advisor: Good carpet cleaning and LiDAR navigation, but mopping mostly spread mess and it got stuck on furniture bases and thin table legs. Source
iRobot Roomba Max 775 Combo
- Gizmodo: Good vacuuming with no clogs and a streak free roller mop that handled ketchup about as well as rivals, but noisy, a buggy app on long runs, unreliable carpet detection and trapped twice under a bed. A full vacuum and mop of 750 sq ft took about 2.5 hours. Source
- Tom's Guide: Hard to recommend. Hardwood pickup of 44% hair, 86.5% Rice Krispies and 91% chia seeds; carpet 52%, 63.5% and 35%. Bumped walls often, scattered debris with its side brushes and left slight mop residue. Source
- Xataka: Excellent pet hair pickup and effective hot water roller mopping; cleaned 55 m² in 40 minutes using 33% of the battery. Fixed side brushes made corners less thorough and bags and solution are costly. Source
