Abstract: A surface cleaner (10) includes a housing (12) having a first tank guide projection (82) that is received in a first recess of a supply tank (14) when the supply tank is in a supply tank operating position and the first tank guide projection includes a cooling air inlet (85) in fluid communication with a cooling air inlet of a pump housing (72). The housing further includes a second tank guide projection (84) that is received in a second recess of the supply tank when the supply tank is in the supply tank operating position and the second tank guide projection forms a cooling air flow path between the cooling air inlet of the first tank guide and the cooling air inlet of the pump housing.

Abstract: A cleaning head for a cleaning machine that cleans a surface includes a housing defining a bottom that faces the surface to be cleaned, and a top spaced above the bottom. A brushroll positioned near the bottom of the housing to engage the surface during operation. The brushroll is releaseably connected to the housing; the brushroll is removable in an upward direction from the top of the housing. A suction nozzle has an inlet that draws debris from the surface into the suction nozzle. The suction nozzle is releaseably connected to the housing; the suction nozzle is removable in a downward direction from the bottom of the housing.

Abstract: A surface cleaner includes a base movable over a surface to be cleaned and having a suction inlet and a brushroll removably coupled to the base and rotatable about a brushroll axis, and a brushroll cover coupled to the base. A latch is movable between an unlocked position in which the brushroll is removable from the base and a locked position in which the brushroll is coupled to the base. The brushroll cover includes an actuator that moves the latch from the unlocked position toward the locked position when the brushroll cover is attached to the base such that when the brushroll cover is coupled to the base, the latch is retained in the locked position by the actuator to prevent removal of the brushroll. When the brushroll cover is uncoupled from the base, the latch moves to the unlocked position such that the brushroll is removable from the base.
