Abstract
A cleaning machine for floors and carpets includes a vacuum pick-up in front of the machine for suctioning loose material and debris off the floor. A microfiber cleaning assembly is mounted beneath the machine for cleaning the floor following the vacuum pick-up. The microfiber cleaning element may be motor driven. A source of solution delivers a controlled amount of solution or water to moisten the microfiber cloth. A vacuum motor provides suction to the forward vacuum pick-up, routes the suctioned air through a filter, and the filtered air is then delivered to an air diffuser to dry any residual moisture behind the microfiber cleaning assembly. The microfiber cleaning assembly may have two offset pads driven by a reciprocating or oscillating drive, or one or two cylindrical rollers for receiving and securing the microfiber fabric in the form of a sleeve.
