Abstract (en)
[origin: US2008022485A1] A surface cleaning apparatus comprising a debris retrieval body ( 3; 203; 403 ) and at least one collection means ( 67; 69; 259; 413; 447 ) provided within the debris retrieval body for accumulating debris from a surface to be cleaned. A rotatable elongate brush arrangement ( 39; 223; 427 ) is also provided within the debris retrieval body to retrieve a first portion of debris from the surface to be cleaned and to direct the first portion of the debris along a first pathway ( 301; 310; 311 ) into the at least one collection means. An inlet aperture ( 61; 255; 475; 485 ) is provided in the debris retrieval body for the passage along a second pathway ( 303; 312; 313; 315 ), independent of the first pathway, of a second portion of debris from the surface to be cleaned. The inlet aperture is formed in a chamber ( 57; 243; 469; 479 ) provided within the debris retrieval body and communicating with a means for creating suction, and the inlet aperture has an area less than the cross-sectional area of the chamber such that the speed of air flow through the inlet aperture as a result of the means for creating suction is high relative to the speed of air flow in the chamber.
