Patent number: 6029311Abstract: A vacuum assisted broom for sweeping floors having a sweeping member, preferably in the form of a plurality of stiff bristles, for bi-directional sweeping of the floor. The sweeping member is operatively mounted within a housing member, which housing member partially encloses the sweeping member within its hollow interior such that the bristles depend from the housing member through a first opening. A handle member is securely attached to the housing member and extends upwardly therefrom. The sweeping member has bristles which are extended such that the broom may be used as a conventional broom, and as a vacuum pick-up. An electrical switch is actuated so as to turn on a suction means that is operatively connected to the interior of the housing member, thus to create a partial vacuum, at the first opening of the housing member.Type: GrantFiled: March 2, 1998Date of Patent: February 29, 2000Inventors: Iberio E.

Patent number: 6009594Abstract: In a cleaning head (10) of the kind having agitating means (26) engageable with a surface to be cleaned for agitating cleaning liquid thereon, and collecting means (25) for collection of liquid from the surface by suction, the agitating means (26) and collection means (25) are relatively movable such that one or the other is selectively prominently engaged with the surface being cleaned. In a preferred arrangement the agitating means (26) is movable relative to a housing (11) of the cleaning head while the collecting means (25) is fixed in position relative to the housing (11). Cleaning liquid is delivered to the agitating means through a passage (45) which is closed by a pad (70) at the upper side of the agitating means (26) when the latter is in its raised position. Movement of the agitating means (26) between its raised and lowered positions is controlled by means of a foot pedal (65).Type: GrantFiled: September 10, 1997Date of Patent: January 4, 2000Assignee: Vax LimitedInventor: Nicholas Grey

Patent number: 5625920Abstract: A cleaning tool is disclosed that includes a brush unit having bristles that is positionable in each of a selected one of a cleaning position and a storage position. In the cleaning position, the brush bristles contact the surface being cleaned using the tool. In the storage position, the brush bristles face in a different direction from the cleaning position and do not contact any surface being cleaned. The tool includes an attachment member for receiving the brush unit. In order to change the position of the brush unit, it is removed from remaining parts of the tool and rotated or otherwise changed in position before re-joining it to the attachment member. In changing between cleaning and storage positions, the ends of the brush unit are disposed at opposite ends of the attachment member. Preferably, the cleaning tool includes a spray control assembly for controlling the spraying of a liquid cleaner during use of the cleaning tool.Type: GrantFiled: October 31, 1995Date of Patent: May 6, 1997Assignee: Windsor Industries, Inc.Inventors: Frederick M.
