Abstract

The present invention relates to a home cleaning appliance (10) including a housing including a nozzle (12) having a main suction opening (24) and a brush. An air stream suction source (16), mounted to the housing, includes a suction airstream inlet (62) and a suction airstream outlet. The suction source selectively establishes and maintains a suction airstream from the nozzle main suction opening to the airstream outlet. A cyclone main body (70) is mounted to the housing and is in communication with the nozzle main suction opening. The cyclone main body includes an upstream, first, cyclonic separator (88) for separating dust from dust-laden air, and at least one downstream, second, cyclonic separator (90) for separating remaining dust particles from the air. A dirt cup (80) is connected to the cyclone main body. The dirt cup includes a first particle collector (82) communicating with the first separator for collecting dust particles separated by the first separator, and a second particle collector (84) communicating with the at least one second separator for collecting dust particles separated by the at least one second separator. The first particle collector and the second particle collector are configured to empty independently of each other.
