## 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 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.

- 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](https://justadadapproved.com/product/irobot-roomba-plus-415-robot-vacuum-and-mop-review/)
