Roomba Combo 10 Max robot + AutoWash dock is our most powerful cleaning robot yet. It vacuums with 100% more suction power*, mops back-and-forth with downward pressure-and learns which rooms get dirty fastest and gives them the deep cleaning they deserve. With advanced smart navigation, it knows how to get around any home and clean each area in the optimal way. Even the dock is smart, automatic bin emptying, liquid refills, washing the mop pad, and pumping clean water through the dock to ensure it stays clean. When your cleaning robot is designed smarter, it makes your life easier. *Compared to Roomba Combo i Series robots. Material: ABS Plastic.
