    Abstract: A floor cleaning machine has a housing and a movable hood that covers over vacuum and liquid hoses of the machine that are visible in prior art floor cleaning machines. The vacuum and liquid hoses are each pivotally connected to a wall of the machine housing and are also pivotally connected to a transparent dome provided on the hood. These connections reduce stresses on the hoses when the hood is moved and allow the dome to pivot relative to the hood. The floor cleaning machine also has a pair of slit orifices that eject fan spray patterns of cleaning liquid that are non-coplanar and do not intersect each other. Furthermore, the floor cleaning machine has an oscillating brush assembly that includes a brush that is replaceable without using tools. The brush height can be adjusted via an adjustment member provided on the oscillating portion of the assembly.

  • Patent number: 6859976
    Abstract: A cleaning apparatus includes a housing to be moved along a surface to be cleaned. Within the housing, a cleaning ribbon is disposed between a supply reel and a take-up reel. A portion of the cleaning ribbon is held parallel to, and in substantial contact with, the surface to be cleaned, for attracting and retaining smaller debris. Another portion of the cleaning ribbon is configured to create a particle trap. A rotatable brush, also disposed within the housing, sweeps larger debris into the particle trap. The supply reel, the take-up reel, the cleaning ribbon, and/or the rotatable brush are alternatively included in a cartridge which is detachably secured within the housing.

  • Publication number: 20040068829
    Abstract: (57) A cleaning head (30) for a vacuum cleaner comprises a housing (305) which extends transversely to the direction of intended movement (A) of the head. A row of bristles (310) extend outwardly from the sides of the housing (305). The bristles (310) extend transversely outwardly and forwardly from the housing and extend to a level beneath the lowermost surface of the housing. Dirt, dust and other debris which collects at the very edge of a room is either ‘guided’ out of the region next to the wall or is subjected to a vigorous ‘flicking’ action as the head (30) is moved across the floor. A suction channel (330) is located adjacent to the bristles. The bristles (310) are provided as a unit which is removable from the head (30).

  • Patent number: 6539575
    Abstract: An agitator for use with cleaning machines, as well as methods for making the same, are shown and described. The agitator is configured to facilitate the removal of elongated fibers therefrom. In one embodiment, the agitator has a rotatable member with opposing first and second ends, an axis of rotation extending between the first and second ends, and an external surface extending at least partially between the first and second ends. A number of projections are attached to the external surface of the agitator. One or both of the ends of the agitator are configured to rotatably engage the cleaning machine, such as at a bearing or other connector. The external surface of the rotatable member has a first portion that is substantially cylindrical about the axis of rotation, and a second portion separate from the first portion that has at least a first depression.

  • Patent number: 6463623
    Abstract: A power brush assembly for vacuum cleaners is disclosed. In the power brush assembly, a casing is set in the suction part of a vacuum cleaner and defines a suction nozzle used for sucking dust-laden air under pressure into the suction part of the vacuum cleaner. A power brush is set within the casing such that the brush is rotatable and reciprocable to the left and right. This power brush is used for brushing dust and impurities on a target surface. A drive motor generates a rotating force for allowing the power brush to rotate and reciprocate to the left and right within the casing. A power transmission mechanism connects the drive motor to the power brush so as to transmit the rotating force of the drive motor to the power brush.
