Abstract (en)
A suction cleaner includes a first separation stage in the form of a cyclone (14) from which air descends in an inner helical flow to a debris collection chamber (23), then ascends in an outer helical flow to pass through a filter (28), a ring of blades (30) forming a further separation stage, a second filter (33) and final pleated paper filters (13) arranged around the cyclone. Large solids are separated in chamber (23) by virtue of the change in velocity, protecting filters (13) from impact damage and clogging.
