Abstract
A hood with a depending side wall has vacuum passages formed in the inner surface thereof. An inner shroud positioned internally of the hood cooperates therewith in forming the vacuum passages and has a lower edge elevated above the surface to be cleaned. A foramenous skirt depends from the lower edge of the hood sidewall to contact the surface to be cleaned. The vacuum passages are connected to a source of vacuum. A rotating spray assembly inside the shroud sprays cleaning liquid onto the surface to be cleaned.
