Washing devices comprise an integrally formed brush component including a hub having a central axis and a plurality of bristles. Each bristle includes a shaft extending from the hub and having outwardly extending cleaning structures. The bristles extend radially from the central axis of the hub. A cylindrical support comprises a webbing having an array of holes positioned to receive the bristles of the brush component, each of the bristles being received within and extending outwardly from respective holes in the webbing. Alternate embodiments comprise an integrally-formed, linear brush component including a plurality of connected hub elements, each hub element carrying a bristle. Each bristle includes an elongated shaft having multiple cleaning structures extending outwardly. A webbing comprises an array of holes positioned to receive the bristles of the linear brush component, each of the bristles being received within and extending outwardly from respective holes in the webbing.

Various embodiments of sponges are disclosed. A sponge may include a sponge body and a soap container. The sponge may include a soap dispensing member disposed within the sponge body and may include a plurality of apertures to establish fluid communication from inside the soap dispensing member to the sponge body. A first end of the soap dispensing member may be in fluid communication with the soap container. A second end of the soap dispensing member may be closed and terminate inside the sponge body, or it may extend to a second end of the sponge body and be enclosed by a removable plug. The soap container may be removably secured to the sponge body or the soap dispensing member, such as with an annular flange connected to the sponge body. A sponge may include a second soap container, and/or a plurality of nubs projecting the sponge body.

An overhead vehicle wash mitter apparatus is provided. A mitter curtain can include multiple mitters that sway above a vehicle pathway as a vehicle travels along the pathway. Each mitter can include an upper end and a lower end closer to the vehicle pathway, a sheath defining an interior tube and an exterior surface that engages a vehicle surface, and a pad in the sheath. The pad can press outward on the sheath so that the sheath attains a first thickness, which can be at least ½ inch, at least 1 inch, at least 1½ inch or more, so the sheath is impaired from entering between a wiper and a surface of the vehicle, such as a window. Accordingly, damage to the wiper of the vehicle is prevented when the mitter engages the surface and the wiper. A related method of use is provided.

This invention relates to an automatic vehicle wash apparatus employing one or more rotary cloth or foam rubber brushes, and more particularly to the way how the rotary brush to vehicle surface contact is managed using one or more encoders connected to the rotating shaft of each brush and one or more programmable logic controllers (PLC). The encoders, recording the revolutions per minute (RPM) of each brush shaft, provide input to the programmable logic controller. If the RPM value is at or above the high RPM limit, the pivoted boom will move the brush toward the vehicle to achieve a desired brush-to-washable surface contact. If, on the other hand, the RPM value is at or below the low RPM limit, the pivoted boom will move the brush away from the vehicle to achieve a desired brush-to-washable surface contact.

The present invention relates generally to the field of pressure washer wands and a cleaning attachment that can be attached to any standard pressure washer wand. The attachment has a roller assembly with a bristled roller head. The head can be positioned in front of the spray tip of a wand such that water that exits the wand and causes the head to spin.

A portable foam brush assembly having a base having a soap supply, a water supply, and an electrical supply. A foam brush wand is detachably dockable to the base and in electrical and fluid communication with the foam brush wand having battery pack, a peristaltic pump, a reservoir chamber, a foaming chamber, an air pump, a brush and a momentary release switch. The base water supply and the base soap supply, when activated, are configured to travel by a water supply hose and a soap supply hose to a tee in the base where they are combined in a combined hose to a base quick coupler that is connectable to a reciprocal foam brush wand quick coupler, which has a foam brush wand hose to deliver the water soap mixture to bladder in the foam brush wand.

An apparatus for treating a vehicle surface with a fluid has a rotation device pivotably mounted about an axis of rotation, and a fluid supply device disposed concentrically with respect to the rotation device and which has an inlet opening for the supply of fluid. The apparatus is characterized in that a groove is formed in the fluid supply device. The groove is fluidically connected to the inlet opening and extends in the circumferential direction with respect to the axis of rotation over a limited circumferential angle range of the fluid supply device. The rotation device has a plurality of separate fluid channels, each of which opens into openings. The openings are disposed such that irrespective of the angular position of the rotation device to the fluid supply device with respect to the axis of rotation, and at least one of the openings of the rotation device is fluidically connected to the groove of the fluid supply device.

A tri-pad scrubbing device primarily used for cleaning vehicles where the scrubbing pads are powered by a single gear motor and each pad is capable of rotating and tilting to conform to the compound curves of a vehicle to allow the pads to maintain full contact with the surface being scrubbed. The tri-pad assembly is attached to the distal end of an adjustable length extension pole. A rechargeable battery power supply, which powers the gear motor, is removably mounted near the proximal end of the extension pole. The tri-pad assembly is attached to the distal end of the extension pole via a rotating and locking hinge mechanism. A push button switch is provided near the extension pole handle end.
