Abstract

The carpet/floor cleaning wand has a vacuum tube with a first section extending roughly parallel to the ground and a second section angled in an upwards direction from the first section. A vacuum hose connects the vacuum tube to a vacuum source. A vacuum head is connected to the first section of the vacuum tube, the vacuum head having bristles therearound and a squeegee attached to the front of the vacuum head. A wheel assembly is releasably mounted onto the vacuum tube. A brush assembly having a motor and a brush is mounted behind the vacuum head. A spray assembly is comprised of a spray manifold mounted behind the vacuum head, a plurality of spray heads emanating from the spray manifold, a fluid feeding tube extending from the spray manifold and to a flow regulator.
