- 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 low cost way into hot water mop washing for homes with mostly hard floors. Vacuum Wars found its mopping above average but its pet hair pickup and obstacle avoidance poor. Skip it if you have shedding pets or cluttered floors.

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
Roborock Qrevo S Pro
- Vacuum Wars (2.70 Vacuum Wars stars): Strong mopping (39.4 vs 31.1 average) and 81% carpet deep clean, but 43% pet hair pickup, 62% long hair wrap and only 5 of 24 obstacles avoided. Estimated 1,495 sq ft per charge. Source
- T3: UK review measured 64 dB vacuuming, 52 dB mopping and 70 dB emptying. It switched well between carpet and hard floor, but missed some debris on textured rugs and handled large dried cereal poorly. Source
