A wheel brush for a wheelchair has a brush assembly that is slidably disposed within a main housing and biased therein via a spring. A brush head is held within one end of the brush assembly so that a portion of the bristles of the assembly extend beyond an open end of the main housing. The device is attached to a brake arm of the wheelchair via a mount member that has a channel such that the brake arm is received within the channel. The wheellock assembly pushes the device toward a rear wheel of the wheelchair such that the bristles engage the wheel and brush dirt off the wheel as the wheelchair rolls being biased thereonto by the spring. The mount member acts as the brake arm for the wheelchair.

A sensor generates an output signal indicative of an attribute of a limited amount of material above the sensor. A controller receives the output signal and incorporates a corresponding variable into a programmatic calculation of an indication of a volume of material in a tank.

The systems and methods of automatically cleaning a wheel are disclosed herein. The systems and methods include a foreign matter detector arranged adjacent to the wheel, a cleaning device arranged adjacent to the wheel, one or more processors communicatively coupled to the foreign matter detector and the cleaning device; and a non-transitory, processor-readable storage medium communicatively coupled to the one or more processors. The non-transitory, processor-readable storage medium includes one or more programming instructions stored thereon that, when executed, cause the one or more processors to: receive a signal from the foreign matter detector, the signal being indicative of possible foreign matter present on a surface of the wheel, determine from the signal, whether foreign matter is present on the wheel, and direct the cleaning device to remove the foreign matter from the wheel.

A wheelchair wheel cleaning assembly includes a clamp that has a space integrated therein to insertably receive a frame of a wheelchair. A pair of fasteners is each extendable through the clamp to attach the clamp to the wheelchair. A lever is pivotally coupled to the clamp and the lever is positionable between an engaging position and a disengaging position. An arm is coupled to and extends laterally away from the lever and a leg is in communication with the lever. An arm scrubber is disposed on the arm to scrub the rear wheel of the wheelchair when the lever is in the engaging position. A leg scrubber is disposed on the leg to scrub the front wheel of the wheelchair when the lever is in the engaging position.

A wheel brush for a wheelchair has an inverted U-shaped brush housing that has a longitudinal channel and an open bottom. A brush head is slidably received within the channel such that bristles located on the brush head extend out through the open bottom of the brush housing. The open bottom is sufficiently narrow as to prevent the brush head from passing therepast. A resilient clip is attached to the brush housing and is clipped to a vertical post of the wheelchair, such as the arm rest post, and is positioned so that the bristles engage a portion of the outer periphery of one of the wheels so as to brush clean the wheels whenever the wheelchair rolls and the rear wheels rotate.

A scraper for removing debris from between first and second tires of a vehicle is provided. The scraper may include a tower, a bracing arm, and a scraper. The tower may have a first end, a second end, and a longitudinal axis extending between the first and second ends, the first end couples to a first portion of the vehicle. The bracing arm may have a first end coupled to the tower and a second end coupled to a second portion of the vehicle that is different from the first portion of the vehicle. The paddle may be suspended by the tower and extends at least partially between the first and second tires of the vehicle. An angle between the bracing arm and the tower may be in a range of approximately 10 degrees to approximately 90 degrees relative to the longitudinal axis of the tower.
