The 4-stage cleaning system delivers high-performance cleaning by combining 70X more intense power-lifting suction, an edge-sweeping brush that cleans 20% better, a multi-surface brush to pick up all kinds of dirt, and a washable, re-usable microfiber pad to wipe away spills. ClearView LiDAR quickly maps your home for precise coverage. Choose from 3 cleaning options - mop, vacuum, or vacuum-and-mop at the same time.
