A cleaning apparatus is disclosed for extracting a liquid from a surface. The apparatus includes at least one extraction head that has at least one aperture that is facing the surface to be cleaned. The vacuum cleaner includes a vacuum pathway situated between the at least one extraction head and a riser that is connected to a vacuum motor. The internal surfaces of the vacuum pathway are smooth and the vacuum pathway has certain dimensions and orientations that optimize the extraction of a liquid from a surface.

Vacuum pathway in a cleaning device

A cleaning system is disclosed that includes a vehicle that has a cooling system for circulating a coolant, a diverter coupled with the cooling system that is configured to divert the coolant through a heat exchanger, a pump configured to pump a cleaning solution through the heat exchanger so that the heat exchanger heats the cleaning solution without mixing the coolant and the cleaning solution, and a rotary head cleaner in fluid communication with the heat exchanger for receiving the cleaning solution and applying the cleaning solution to a floor.
