摘要： A vacuum cleaner includes a suction inlet, a suction source configured to generate an airflow through the suction inlet to draw debris with the airflow through the suction inlet, and a separator assembly. The separator assembly includes a housing having an air inlet and an air outlet, a debris collection chamber within the housing, and an inner chamber formed within a shroud that defines a cyclone axis and has a perforated portion. The inner chamber has a first end and a second end. The first end has a tangential inlet. The second end is open toward the debris collection chamber. An outflow passageway is outside of the shroud and in fluid communication with the air outlet and a filter is in fluid communication with the outflow passageway.

摘要： A floor cleaner including a recovery tank. The recovery tank includes a tank body having a lower end wall, an open upper end, and a sidewall that extend upwardly from the lower end wall. A cover that includes a suction air outlet in fluid communication with a vacuum source. An inlet duct extends upwardly from the lower end wall. The recover tank includes a shutoff float including a float body and a closure. The float body is configured to float on a surface of cleaning fluid and the closure is received in the suction air outlet to close the suction air outlet. The float body moves along the inlet duct as the float body floats on the surface of the cleaning fluid. The float body includes an aperture extending through the float body and the inlet duct extends through the aperture of the float body.

摘要： A vacuum cleaner including a separator assembly having a container that defines a cyclonic separator about a separator axis. The container having a dirty air inlet that receives the airflow and debris to rotate around the separator axis in a first direction. A clean air outlet discharges the airflow from the separator assembly. A shroud forming an airflow passageway is between the dirty air inlet and the clean air outlet. The airflow passageway is formed by a plurality of vanes defining openings between adjacent vanes positioned to direct the airflow and debris in a second direction at least partially opposed to the first direction redirecting airflow into the shroud. A mesh screen is positioned on the shroud covering the airflow passageway and a filter at least partially within the shroud extends around the separator axis positioned in an airflow path between the plurality of vanes and the clean air outlet.
