The motorized cleaning head is attached to the mobile body and is configured to perform sweeping and scrubbing operations on the surface. The waste hopper is positioned on a rear side (136) of the cleaning head and is configured to receive waste (128) discharged from the cleaning head during the surface sweeping operations. The hopper lift is configured to raise the waste hopper from an operating position (180), in which the waste hopper is positioned adjacent the cleaning head, to a dumping position (182), in which the waste hopper is positioned to dump waste collected in the waste hopper. In one embodiment, the vacuum squeegee is attached to the hopper lift. Also disclosed is a method of cleaning a surface using embodiments of the machine.
