Patent attributes
The present invention relates to a home cleaning appliance including a housing including a nozzle having a main suction opening and a brush. An air stream suction source, mounted to the housing, includes a suction airstream inlet 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 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 for separating dust from dust-laden air, and at least one downstream, second, cyclonic separator for separating remaining dust particles from the air. A dirt cup is connected to the cyclone main body. The dirt cup includes a first particle collector communicating with the first separator for collecting dust particles separated by the first separator, and a second particle collector 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.
