Abstract: A floor cleaner brush arrangement includes a housing having mounted thereto a plurality of adjacent rotating brush assemblies. The rotating brush assemblies each include bristles extending there-from downwardly to the floor and outwardly into an overlapping and intermeshing relationship with the bristles of the brush assembly or assemblies adjacent thereto. The bristles of adjacent brush assemblies cooperate when rotating to contact the floor in overlapping fashion to eliminate cleaning blind spots.

Abstract: A water pump for use in steam cleaning devices includes a plunger pump with check valve and a transmission assembly. The plunger pump with check valve includes a water inlet and a water outlet. The transmission assembly includes a gear transmission system, an eccentric wheel, and a plunger pump push block. The output shaft of the gear transmission system drives rotation of an eccentric wheel. The push block has a reset structure which makes one end of the push block engage the eccentric wheel. The other end of the push block engages a plunger of the plunger pump with check valve. The pump has a simple structural arrangement, requires no additional power source, and provides consistent water flow at a low manufacturing cost.
