ABSTRACT:
A cleaning appliance includes a main body and a collecting chamber releasably held on the main body. The collecting chamber includes a closure member which is movable between a closed position and an open position in which the collecting chamber can be emptied and an actuating member adapted and arranged to release the collecting chamber from the main body and, when the collecting chamber is released from the main body, to release the closure member from the closed position. By providing such an arrangement, a single actuating member can be used to release the collecting chamber from the main body of the cleaning appliance and also to open the closure member to empty the collecting chamber. A single actuating member is less complex, requires less space and is more intuitive for a user to operate.
