Abstract

A carpet washing attachment with a vacuum hose attached to a washing head with a liquid line feeding water/cleaning fluid into washing head is disclosed. Washing head is formed of hollow members and a cover sealed to the top washing head with the vacuum hose attached to the cover. This forms cleaning area which is surrounded by the hollow members. Each of the hollow members has water jet holes located on the inner part of the washing head such that the water exiting the holes is projected inward so that the jets of water come to an apex and intersect at a given distance X from the bottom of the washing head. The angle of the jets and the spacing of members should be chosen such that the distance X is roughly the depth of the carpet pile to be washed.

Claims

1. A carpet washing device comprising:

a washing head comprising at least four fluid connected hollow members, said hollow members enclosing a roughly rectangular cleaning space;

a vacuum hose attached to the washing head providing suction to the cleaning space;

a liquid line attached to the washing head to deliver liquid to the hollow members;

the hollow members having jet holes for directing water in controlled streams onto the surface to be cleaned, the jet holes arranged such that the streams of water are angled inward towards the inside of the cleaning space;

the jet holes producing a largely uni-directional stream of water;

wherein the jet holes are positioned such that the streams of water from at least one set of hollow members on opposing sides of the cleaning space from each other intersect at a distance X from a bottom of the cleaning head, the distance X being the depth of a carpet pile to be cleaned; and

the two opposing streams of water combining to provide a scrubbing action to a carpet to be washed.

2. The carpet washing device of claim 1 wherein, the angle of the streams of water is at 30 degrees from the vertical.

3. The carpet washing device of claim 1 wherein the angle of the water streams is adjustable.

4. The carpet washing device of claim 1 wherein the spacing of the hollow members is adjustable.
