Abstract
A cleaning head housing for a floor cleaner that moves along a surface to be cleaned includes a brushroll chamber defining a top surface having a top opening and a bottom surface having a bottom opening positioned closer to the surface to be cleaned than the top opening. A suction nozzle has an upper nozzle wall, a lower nozzle wall, and a nozzle passageway formed between the upper and lower nozzle walls. The suction nozzle is releaseably connected to the brushroll chamber to selectively cover the top opening of the brushroll chamber. A brushroll is positioned within the brushroll chamber and engages the surface to be cleaned through the bottom opening of the brushroll chamber. The brushroll is accessible through the top opening for cleaning while the suction nozzle is disconnected from the brushroll chamber. The brushroll is removable from the brushroll chamber other than through the top opening.
