## What reviewers found

### iRobot Roomba Max 715 Vac + AutoEmpty Dock

- PCWorld: Initial mapping took about 13 min. Strong on a rug but weak on hard floors at Standard suction until Deep or Smart mode. Handled furniture well but pushed through shoes and chewed up magazines. Loud auto empty. [Source](https://www.pcworld.com/article/3265229/roomba-max-715-vac-review.html)
- Just A Dad Approved (6/10): Three months of home use: carpet 8/10, clutter test 8.5/10, hair tangle 6/10. The dock failed to fully empty the bin in 5 of 5 tries and moist mess pickup failed. [Source](https://justadadapproved.com/product/irobot-roomba-max-715-pet-robot-vacuum-review/)

### 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)
