Abstract
A brush has first and second faces and first and second brush portions on the first and second faces, respectively. The tuft bristles used to make the first portion are of a size different from those used to make the second portion, thereby providing brush portions of differing stiffness for removing spots from different types of carpet. The tufts of the brush portions are in a unique pattern particularly well suited for using the brush with a dry granular carpet cleaning product. Each brush portion is defined by rows of bristle tufts disposed along respective row axes oriented in the direction of normal brushing. The tufts are generously spaced from one another (both laterally and longitudinally) so that carpet can be cleaned with a granular cleaning product while yet avoiding brush packing with the product. A new method for removing a spot from a carpet is also disclosed.
