  • Patent number: 6813807
    Abstract: A vacuum cleaner includes a body having a container which collects dirt and dust. A surface cleaning head defining a primary dirt and dust collection inlet is configured to contact a surface over which the surface cleaning head is moved. A passageway connects the primary inlet to the container. A secondary dirt and dust collection inlet is remote from the primary inlet and spaced from the surface. The cleaner suctions dirt and dust through the primary and secondary inlets into the container. The primary inlet is adapted to draw surface-borne dirt and dust efficiently into the container and the secondary inlet is adapted to draw airborne dirt and dust efficiently into the container. Dampening means are provided to at least one of the primary inlet and the secondary inlet and is controlled by an actuator activated directly or indirectly by an operator of the vacuum cleaner.

  • Patent number: 6370453
    Abstract: A self-moving device and method for the complete and full automatic examination of floor surfaces of all kind as well as for a particularly efficient suction of dust therefrom. In each case, the robot is controlled so as to explore the adjacent area and to detect the potential obstacles using special sensors before storing them in a data field. The displacement towards a new location is then carried out using the stored data until the whole accessible surface has been covered. One of the main constituent members of the robot includes an extensible arm that rests on the robot and on which contact and range sensors are arranged. When the robot is used as an automatic vacuum cleaner, an air flow is forced into the robot arm and the cleaning effect can further be enhanced by providing one or more circular rotary brushes at the front end of the arm. This device can essentially be used for domestic or industrial cleaning purposes with a view to replace traditional vacuum cleaners.

When a smaller floor area is to be cleaned, the smaller scrubbing machine is removed from the larger scrubbing machine. The smaller scrubbing machine includes a scrubber assembly and a motor that is powered using an electrical power source located on the larger machine. A spring is operatively connected to this scrubber assembly for ensuring desired contact between the brush bristles and the floor area being cleaned. Two spaced pairs of wheels provide a uniform plane of contact during scrubbing by the scrubber assembly.

  • Patent number: 5933912
    Abstract: An upright wet extractor includes a base assembly, a manipulative handle pivotally attached to the base assembly, and a motor driven agitator brush. A cleaning solution dispensing tank is removably attached to the handle assembly by a pivotable latch member. In a floor cleaning mode, cleaning solution is selectively supplied by gravity from the dispensing tank to a floor cleaning spray nozzle through a supply tube which is controlled by a pinch valve. In an attachment hose cleaning mode, cleaning solution is selectively supplied by a motor driven pump from the dispensing tank to an attachment hose spray nozzle which is controlled by a trigger valve. A suction motor/fan assembly is carried by the base assembly which is selectively in fluid communication with a floor suction nozzle in the floor cleaning mode and an attachment hose suction nozzle when in the attachment hose cleaning mode.

  • Patent number: 5815883
    Abstract: The problem with suction lines on vacuum cleaners is that the connected vacuum hose must be lifted during when the suction pipe is rotated. To eliminate this problem, the invention teaches that an elbow is interposed between the suction pipe and the suction hose which is mounted by means of a rotating knuckle, as a result of which the suction hose can be adjusted as required, and the suction pipe can be ergonomically manipulated by means of an angled gripping area of the handle.

  • Patent number: 5720075
    Abstract: The present invention relates to a suction apparatus to be connected to a machine of the textile processing or prepration industry connected to a suction system (1a, 1b, 14) with a work area (a) and a first suction apparatus (3) which is stationary in the surrounding of the work area for the aspiration of fibers, small parts and/or particles (dirt) from the work area. With it a machine cleaning system is created which is able to clean problem zones of the work area of a machine without imosing a load on the space surrounding the machine. This is achieved if a second suction line (4, 16) in form of a hose that is flexible at least in sections the end (6) of which opening towards the work area (A) of the machine is freely movable for cleaning while its end attached to the machine is connected to the suction system (1a, 1b, 14) in order to introduce the aspired dirt into the suction system.

  • Patent number: 5655254
    Abstract: A cleaning machine is provided with a recovery tank for containing recovered liquid from a floor or other surface that is being cleaned. The recovery tank has a chamber that houses the recovered liquid and within the chamber are a recovery inlet and a vacuum conduit. The recovery inlet carries the recovered fluid for discharge into the chamber and the vacuum conduit is used in creating a desired vacuum to cause the recovered liquid to be drawn into the chamber. The recovery tank is disposed on a cleaning tank for containing a liquid cleaning solution that is applied to the surface for cleaning purposes. The recovery tank covers an access opening in the cleaning tank for receipt of the liquid cleaning solution. A vacuum motor produces the vacuum and is located next to the cleaning tank below the recovery tank. Sealing members insure a proper seal at the junctions for the recovered liquid and the vacuum when the removable tank is joined to the cleaning tank.

  • Patent number: 5560074
    Abstract: A convertible vacuum cleaner operable in both on-the-floor and above-the-floor cleaning operations is shown. Depending upon the location of the handle which is pivotally supported by the vacuum foot, a conversion valve interconnected to the handle automatically converts the vacuum between on-the-floor and above-the-floor cleaning operations. The conversion valve includes a flapper valve member which is actuated between a first position blocking fluid communication between the vacuum motor and the brush roll chamber and a second position blocking fluid communication between the vacuum motor and the accessory hose. The valve member is actuated between these two positions by a pin and actuator arm provided on the pivotally mounted valve member. The pin is received in a contoured groove formed on the motor housing and the motor housing is securely mounted to the handle and pivotally mounted with respect to the foot and valve member.

  • Patent number: 5367738
    Abstract: A device for cleaning rows of machines, such as textile machines, which can travel along the machines and has a blower guided above the machines, whose pressure side is connected to a distributor station. At least two hoses are attached via connecting pieces to the distributor station which have different openings directed to the machines. A slider is located on the distributor station which distributes the air supplied to the distributor station in accordance with its position on the connecting pieces. A number of hoses can be attached to the device, and the hose to be charged with air can be easily selected by a slider which can travel along the row of connecting pieces. The slider has a through-hole which, when the slider is moved, successively coincides with the connecting pieces. A flexible hose which leads to the pressure side of the blower and surrounds the through-hole, is attached to the side of the slider facing away from the connecting pieces.

  • Patent number: 5347678
    Abstract: A cleaning head assembly for a vacuum cleaning apparatus of the wet, dry and wet/dry types includes a rotatably driven brush carried within and laterally spanning the head assembly. A pair of floating vacuum heads are positioned on opposite sides of a housing for the brush, and each defines a portion of a vacuum pathway having an inlet opening adjacent to the surface to be cleaned, which extends from the inlet opening to a dirt collection zone within the vacuum cleaning apparatus. The floating vacuum heads are each attached to the brush housing in a manner permitting relative movement therebetween. In this regard, a track fixed to the brush housing engages a generally vertically extending flange extending from a vacuum head such that the flange moves within the track to control movement of the vacuum head relative to the brush housing. A roller spaces the flange from the track to minimize frictional contact therebetween, and a stop pin limits relative movement between the vacuum head and the track.
