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.
