Abstract
A vacuum cleaner comprises a cylconic separation unit with a dirty air inlet and a cleaned air outlet at a first end and a dirt collection portion at a second end. The separation unit is supported on the cleaner such that the inlet is located in a lower portion of the first end and such that, in normal use, the longitudinal axis of the chamber lies in, or can be brought to lie in, a substantially horizontal position. A shield member is provided at the inlet for shielding the inlet from the dirt collection portion of the chamber. This helps to prevent dirt from becoming re-entrained in the airflow and the inlet and dirt from falling from the inlet when a user removes the separation unit. The shield also helps to straighten incoming airflow through the inlet. The shield can be formed integrally with a shroud or other insert that fits inside the separation unit.
