  • Patent number: 8316499
    Abstract: Cleaning devices which use cleaning sheets affixed in traps are disclosed. The traps comprise first and second jaws, each comprising base and forward portions, each forward position having a forward surface. The forward portion of the second jaw is flexible in at least a first direction, such as towards a surface over which the device is configured to move. When the second jaw is relaxed, the forward portion of the second jaw is substantially coplanar with the forward portion of the first jaw and the forward surfaces are proximate or touching. When the second jaw is flexed in the first direction (e.g., by the application of a force from a user), the forward surface of the forward portion of the second jaw moves in the first direction, away from the forward surface of the first jaw. This opens a gap through which a portion of a sheet may be inserted.

  • Patent number: 7950097
    Abstract: A cleaning apparatus is provided for a preferably planar surface, in particular a window pane, and has a wiping device and a plunger which keeps the wiping device in contact with the surface and also, by way of an open side, bears against the surface and seals it around the edge. A suction device generates a negative pressure in the plunger. The plunger is provided with driving rollers, which are actuated by motor, for moving the plunger together with the wiping device. The suction device has at least two fans which are each provided with their own outlet opening.

  • Patent number: 7921497
    Abstract: A floor scrubbing apparatus that is particularly well suited to scrubbing carpet materials is disclosed. The floor scrubbing apparatus is manually operated and includes a drive roller coupled to a scrub roller. In one embodiment, the drive roller is coupled to the scrub roller using a gear arrangement that causes the scrub roller to rotate faster than the drive roller. If desired, the apparatus can include a cleaning fluid dispensing system. For instance, the apparatus can include one or more nozzles that dispense a cleaning fluid onto a carpet material as the material is being cleaned.

  • Patent number: 7908701
    Abstract: An adjustable scrubbing implement for cleaning a surface is disclosed. A resilient base that comprises a center portion and a plurality of resilient fingers each is joined at a proximal end thereof to the center portion and extends radially away therefrom. The rigid cap comprises a side portion fixed at a top end thereof to an inside upper side of the cap, and terminates at a wider open lower end. The inside upper side includes a central aperture therethrough. The cap includes a handle receiving means pivotally fixed thereto for receiving a threaded end of an elongated handle. An adjustment means interposed between the cap and the resilient base moves the center portion of the base relative to the inside upper side of the cap. The downward angle of the fingers are defined by the relative distance between the center portion of the base and the inside upper side of the cap.

  • Publication number: 20110047730
    Abstract: A chemical distribution system for a floor cleaning machine is described. The system utilizes at least one container that is selectively connected to a pump that pumps a cleaning chemical solution from the container into a tee for combining with a fluid from an onboard fluid tank at a rate determined by a machine operator. Chemical containers may be readily and interchangeably connected to the pump to permit various solutions to be selectively utilized to optimize floor cleaning.

  • Patent number: 7895694
    Abstract: This relates generally to devices used in the removal of excess spray-applied insulation from building components, and more particularly to an improved rotary scrubber that is readily extendable for reaching areas of extended elevation. To facilitate the scrubbing of insulation from areas of extended elevation, one embodiment of the scrubber has an adjustable handle assembly connected to the housing. The adjustable handle assembly preferably comprises a receiver connected to the housing and an extension and a support handle adjustably connected with the receiver. The extension preferably defines an extension handle, with the support handle adjustably connected with the receiver forward of the extension handle when the extension is adjustably connected with the receiver. In other embodiments, the scrubber further comprises at least one extender optionally removably connectable between the scrubber's housing and the framework.

  • Patent number: 7850383
    Abstract: A walk-behind floor finish applicator wherein a mop with a handle is connected to the applicator, yet is readily removable therefrom. This allows the mop to be used as a component of the walk-behind applicator for applying floor finish to easily accessible areas in one instance, yet allows the mop to be used independently for application of floor finish to not so easily accessible areas. The applicator is adaptable to receiving bag in the box floor finish, thus reducing cleaning time. The applicator employs a minimum number of disposable parts thus making it economical to produce.

  • Patent number: 7823242
    Abstract: The invention disclosed relates to the remote cleaning of outer surfaces of windows or facades of high rise buildings without the need for workers located outside the building wall. In fact, the cleaning operation effectively duplicates the conventional manual cleaning operation, such that a minimum of cleaning liquid is used, and no means is required for removal of excess cleaning liquid. The apparatus comprises a rectangular master frame and a parallelogram sub-frame contained therein, suspended from the top of the building to a position opposite a window to be cleaned. A novel cleaning tool, including mechanical scrubbing means e.g. a brush and mechanical scraping means e.g. squeegee and a washing liquid spray means, is carried on an insertion tool attached to the parallelogram sub-frame, and brought to bear against the window outer surface to be cleaned, as required.

  • Publication number: 20100218323
    Abstract: The invention relates to a floor-cleaning appliance having a housing, on the underside of which is disposed at least one floor-cleaning tool adapted to be driven in rotation or oscillation, wherein the floor-cleaning appliance, for the purpose of cleaning a floor surface, can be guided manually by the user in an operating direction along the floor surface. In order to develop the floor-cleaning appliance such that it can be transported in a simple manner, it is proposed according to the invention that the floor-cleaning appliance has transporting wheels which are adapted to be rotatably fixed by the user, for the purpose of transporting the floor-cleaning appliance, on wheel bearings disposed on the side of the housing.
