What reviewers found
iRobot Roomba 105 Combo + AutoEmpty Dock
- Just A Dad Approved (4.6/10): After about three months of home use it scored 5.5 of 10 for mopping, 6 for carpet, 5 for hair tangle and 1.5 for obstacle avoidance, running over items under about 3 inches. Only 2 of 6 marketing claims passed. The reviewer advised skipping it at full price. The page prints 4.6/10 in one place and 4.8 out of 10 in another. Source
- Tek.no (Norway): Rated it mediocre. Vacuums well and LiDAR improved navigation over older Roombas, but it got stuck, took a long time, has lower suction than rivals and a basic wet cloth mop. Source
iRobot Roomba Plus 515 Combo
- Just A Dad Approved (6.5/10): 3 month real world test: subscores Hassle Free 6.7/10, Mop Performance 7.2/10, Carpet Cleaning 6.4/10, Hair Tangle 5/10, Obstacle Avoidance 7/10. Reported repeated Wi-Fi disconnects that needed hard reboots, hair wrap on the single brush roll, a slightly off map and a filter that can only be replaced. Says the Amazon only 515X is the same robot. Source
- Lifehacker Japan: Hands on with the Japanese model: measured 8.4 cm tall, cleaned under low sofas and cabinet toe kicks earlier Roombas missed, and avoided a camera placed as an obstacle. The review lists no drawbacks and carries affiliate links. Source
