- 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 compact Roomba that adds an AI camera and a solution dosing hot wash dock to the 400 series formula. European testers found navigation quick and precise and mopping fine for daily spills, but weak on dried stains, and hair wraps the brushes. Pick it for tight spaces with some clutter; skip it if you need deep carpet cleaning.

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 Plus 575 Combo + AutoWash Dock
- Netzwelt (Germany): Picked up 29.1 g of 30 g of test dirt. Fast, precise navigation, cleaned under radiators, handled dried coffee but failed on dried ketchup, and sometimes drove over cables. Hair wrapped both brushes. Source
- Android.com.pl (Poland) (7.8/10): Navigation never failed and it avoided cables, laces and toys. Very good on hard floors, weaker on fine flour in carpet even after two passes. Used about a low teens percent of battery on about 25 m². Repeated Wi-Fi drops in the app. Source
