A vacuum cleaner (10) comprises a cyclonic separation unit (52) with a dirty air inlet (32) and a cleaned air outlet at a first end and a dirt collection portion (74) 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 (90) 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 a the inlet and dirt from falling from the inlet when at 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 (80) or other insert that fits inside the separation unit.
