Abstract (en)
A cleaning head for a wet vacuum cleaner has first and second rotary brushes, each extending across a width of a housing. The housing comprises a first projection extending inwardly into a space between the brushes and having a first guide channel creating an air cavity over the floor, and a second projection extending inwardly the said space. The second projection has a second guide channel creating another cavity over the floor. These cavities promote lateral air flow into the space between the brushes and thereby reduce pooling of water.
