Abstract
A surface cleaning suction type appliance comprises a housing, an airstream suction source, a cyclone main body, and a dirt cup. The housing includes a main suction opening. The airstream suction source is mounted to the housing and includes a suction airstream inlet and a suction airstream outlet. The suction source selectively establishes and maintains a flow of air from the main suction opening, via the airstream inlet, to the airstream outlet. The cyclone main body is supported by the housing and is in communication with the main suction opening. The cyclone main body has a uniform outer circumference and includes a first stage separator, and a plurality of downstream second stage separators. The lengths of the second stage cyclonic separators are different for any number of adjacent pairs of separators from on pair up to all adjacent pairs of separators. The dirt cup is connected to the cyclone main body. The dirt cup includes a first particle collector and a second particle collector. The first particle collector communicates with the first stage separator for collecting dust particles from the first stage separator. The separate second particle collector communicates with the plurality of second stage separators for collecting dust particles from the second stage separators.
