Abstract: A hand held solid pet waste vacuum is described, which allows the sanitary collection of solid pet waste from off of a variety of surfaces (for example dirt, snow, gravel or grass) into a disposable filter bag. The vacuum is powered by a rechargeable battery which can provide 50 clean-ups on a single 12 hour charge and a 30,000 rpm electric vacuum motor. Each disposable filter bag can hold one week's worth of solid pet waste (depending on pet breed and diet), and is completely sanitary, preventing pet waste from coming in contact with either the vacuum or the operator.

Abstract: An convertible central vacuum system is disclosed allowing for operation in both a cyclonic separation (bagless) mode as well as in a filter bag mode (via an removable filter bag adapter housing). With each mode having its own advantages and disadvantages, the user can readily convert between them as desired.

Abstract: A central vacuum wherein said central vacuum comprises a housing with a portion of said housing comprising a motor housing, a filter housing and a dust collecting bin. A motor, power source, foam filter a dust collecting bin are incorporated within the filer housing. The housing further compromising an exhaust outlet, and at least two optional intake ports adapted to receive an intake hose. The first intake port is adapted such that the air and debris received from an intake hose is channeled into the filter where it passes through the filter, trapping dust and debris in the filter. The second intake port is adapted such that the air and debris received from an intake hose is channeled directly into a bag adapter and the air and debris is channeled into a vacuum filter bag, trapping the dust and debris in the bag. With either intake port, the air to flows through the filter or filter bag into the housing, where the air is exhausted through the exhaust outlet.

Abstract: A brush for use with a rotating motor device comprises a collar and a brush-head. The collar has a first open end and a second securing end. The securing end of the collar has a polygonal opening adapted for securely mating with a corresponding polygonal rotating shaft of a rotating motor device, such that when second end of the collar is secured to the rotating shaft, rotation of the shaft causes corresponding rotation of the collar. The brush-head comprises a plurality of bristles cylindrically bundled, said cylindrical bundle having a first fused end and a second loose end, wherein the bristles are securely fused to together at the fused end and the bristles are unattached to each other at the loose end, and the bristles at the loose end define a generally concave brush face wherein the bristles in the center portion are shorter than the bristles in the perimeter portion.
