iRobot Roomba Plus 515 Combo + AutoWash Dock
The Plus 515 is the iRobot model to investigate when a home has plenty of hard floor and the owner wants the dock to handle bin emptying and mop care. Its low height and lifting spinning pads are useful differentiators, but the benefit must justify a much larger dock and a higher price than the simple 115 Combo.
The main things to know before buying are it uses one rubber-and-bristle main brush rather than iRobot's dual-rubber Max-series system and the large AutoWash dock needs hard-floor space and regular clean-water, dirty-water and bag maintenance.
