- 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 slim, low cost entry to iRobot's wash and dry docks, with spinning pads that scrub spills well and a 3.29 in body that fits under low furniture. It has no camera, so testers saw it tangle in cables and push toys around. Buy it for mostly clear hard floors; skip it if you have cords or pet toys on the floor.

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

iRobot Roomba Plus 415 Combo + AutoWash Dock
- Ideal Home: UK test: cleared a BBQ sauce spill in one pass and reached skirting boards, but tangled in charging cables, pushed toys and wrapped hair on the roller. Notes 45°C pad drying versus 75°C washes on some rivals. Source
- Just A Dad Approved (6.2/10): Three months of home use: hassle free 7/10, mop 6/10, carpet 6/10, hair tangle 5/10, clutter 7/10. Pads occasionally detached and it missed cords and small objects. Source
