### iRobot Roomba Plus 505 Combo

- Tom's Guide: Mapped the home in 5 to 7 minutes, avoided shoes and toys, and had no dog hair tangles over 20+ runs. Measured about 65 dB in auto mode and 87 dB when the dock empties the bin. Spot clean was less thorough and the app sometimes glitched. [Source](https://www.tomsguide.com/home/home-appliances/roomba-plus-505-combo-review)
- New Atlas: After one to two months in a family home, praised wall and corner mopping and low upkeep, but found it noisy, saw hair wrap the brush ends, and saw it swallow socks and cables now and then. Called it a great buy at about $599. [Source](https://newatlas.com/around-the-home/roomba-plus-505-combo-review)
