发明名称 Method of cleaning a carpet
摘要 A hand held brush specifically adapted for sweeping and cleaning regions of carpet. The brush is constructed with a handle portion in which is secured a field of bristles in a slanted bristle array. The bristle length tapers downwardly from the frontal edge of the brush to the rear edge and the flexibility varies accordingly. In this manner, the bristles may be swept through an area of carpet to remove both large and small dirt and lint particles by utilizing the varying flexibility of the bristles concomittantly with the tapering length thereacross.
