发明名称 A DEVICE FOR THE CARE OF FLOORS,IN PARTICULAR THE MOUTH PIECE OF A VACUUM CLEANER
摘要 The invention is directed to a floor cleaning apparatus which includes a nozzle-like structure for a vacuum cleaner. The apparatus is for vacuum cleaning and polishing hard floors and is moved by the operator in a desired direction. The apparatus includes a chassis defining a longitudinal axis and at least two working plates for working on the surface of the hard floor. The working plates are movably mounted on the chassis so as to perform respective reciprocal movements counter to each other and in a direction ninety degrees to the desired direction in which the apparatus is moved by the operator. The plates conjointly define a total depth extending in the direction of the longitudinal axis of the chassis and work plate takes up one-third of this depth. The other one of the work plates takes up two-thirds of this depth. The work plates have a flat shape and at least one of the work plates is pervious to air. The work plates are sealed at their edges and are mounted on the apparatus by means of elastic bearings.
