## 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](https://www.techradar.com/home/robot-vacuums/irobot-roomba-205-dustcompactor-combo-review)
- 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](https://www.techadvisor.com/article/2837405/roomba-205-dust-compactor-combo-robot-vacuum-review.html)

### 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](https://www.netzwelt.de/irobot-roomba-plus-575/testbericht.html)
- 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](https://android.com.pl/tech/1093997-recenzja-roomba-plus-575-irobot-opinia/)
