Abstract: A steerable upright vacuum cleaner includes an upright section including a dirt collecting portion, a collar on which the upright section is mounted and base section to which the collar is attached. The upright section is mounted on the collar such that the upright section pivots around a first axis with respect to the collar. The base section is attached to the collar such that the collar pivots around a second axis with respect to the base section. The second axis is approximately perpendicular to the first axis. The base section includes a nozzle that communicates with the dirt collecting portion.

Abstract: The present invention relates to an upright vacuum cleaner including a housing and a nozzle base having a main suction opening. The housing is pivotally mounted on the nozzle base. The housing comprises a cyclonic separator including a dirty air inlet and a sidewall. A lower end of the separator being secured to a lower skirt. A dust collector section is located beneath the separator and includes a sidewall. A perforated tube is disposed within the separator. The perforated tube includes a shroud extending away from a closed lower end of the perforated tube. A diameter of the shroud is larger than a diameter of the separator lower end. The lower skirt and the shroud define a first air channel for directing air from the separator into the dust collector section. The first air channel has a substantially constant volume for maintaining airflow velocity.

Abstract: 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.
