4.0
Edge-following accuracy is supported by one mopping test showing the extending mop pad reaching right next to the wall.
Emptying and Mess Control
P1
Product 1: iRobot Roomba Vac Essential Robot...
2.3
Emptying was a drawback because reviewers had to carry the bin to the trash and empty it manually.
P2
Product 2: Roborock Saros Z70 Robot Vacuum...
