DyadPower System. With dual roller motors and a multi-roller cleaning head, the Roborock Dyad Wet/Dry Vacuum vanquishes wet and dry stains easily, leaving floors dry and clean.
Effective Edge-to-Edge Cleaning. The unique combination of a full-length front roller with the two rear rollers brings cleaning power right to the edge of the brush head. You can clean right into the edges of walls with a single stroke.
Dual Self-cleaning Systems. Brushes clean themselves as you clean the floor, so you never rub a dirty brush on clean floors. After cleanup, the brushes wash themselves once more, ready to go again.
Adaptive Cleaning. Onboard sensors detect how much dirt is being cleaned and automatically adjust water flow and suction power to give you maximum cleaning with minimum work. Wash floors thoroughly with simultaneous vacuuming and mopping, giving you cleaner floors with minimum effort.
Agile Cleaning Head. The head effortlessly flicks up to 180°, making it easy to clean around table legs, chair legs, and other obstacles. Counter rotating rollers also mean you can push and pull using just one finger.
