Abstract
A vacuum cleaner has a removable cyclonic separator that includes a cyclone chamber; a dirt-collection chamber, open at one end; and an outlet duct from the cyclone chamber. An open end of the outlet duct is arranged for connection to a motor intake duct on the cleaner, the outlet duct and dirt collection chamber sharing a common wall section which divides the open end of the outlet duct from the open end of the dirt collection chamber. A cover closes off the open end of the dirt collection chamber and can be opened to allow access to the dirt collection chamber for emptying. When the cover is in the closed position, a cover sealing member forms an air seal between the cover and the common wall section. When the outlet duct is connected to the motor inlet duct, an outlet duct sealing member forms an air seal between the ducts.
