A handheld extractor that includes a housing, a supply tank adjacent a first side of the housing, and a recovery tank adjacent a second side of the housing. A cleaning chamber is in the third side of the housing. A fluid flow path is between the supply tank and the cleaning chamber. The cleaning chamber receives a suction nozzle and a suction source provides suction through a hose and the second fluid flow path to extract the cleaning fluid from the supply tank, along the fluid flow path into the cleaning chamber, through the hose and into the recovery tank to flush the cleaning fluid through the hose to clean the hose when the suction nozzle is received in the cleaning chamber.

A chute control assembly for a snow thrower having a housing, handle, and a chute includes a control mechanism, a connecting mechanism, and a guide mechanism. The control mechanism includes an actuator mechanism that allows an operator to manually control the orientation of the chute from a position spaced apart from the chute. The connecting mechanism transfers rotation of the actuator mechanism to the guide mechanism. The guide mechanism is attached to the chute and rotates and adjust the orientation of the chute in response to rotation of the actuator mechanism in order to change the direction that snow is thrown from the snow thrower.

An upright vacuum cleaner (A) includes an upright housing section (B) and a nozzle section (C). A cyclonic airflow dirt and dust separating chamber () is defined in said upright housing section. A suction source (E) pulls air and entrained dirt, dust, and other contaminants through a main suction opening () formed in the underside () of the nozzle and into the cyclonic airflow chamber (). The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container () that defines the chamber (). A main filter element (K) filters residual contaminants from the suction airstream between the chamber and the suction source. The main filter element is preferably made from high-density polyethylene porous filter media. A final filter assembly (F) filters the suction airstream discharged by the suction source to ensure that the air discharged into the atmosphere is contaminant free, including those contaminants introduced into the airstream by the suction source itself.

A floor cleaning device () includes a housing () and a container () removably received by the housing. A suction nozzle () is fluidly connected with the container and with a suction source () when the container is received by the housing. A filter () is selectively fluidly connected with the container and with the suction source. A float () selectively closes the fluid connection of the filter with the container. The filter and the float may be removable as a unit () from the cleaning device. The nozzle may be removable, allowing an appropriate nozzle to be selected according to the type of floor surface to be cleaned.

Hard floor cleaner

An upright vacuum cleaner includes a nozzle base having a main suction opening formed in an underside thereof. A housing is hingedly connected to the nozzle base. The housing includes a dirt separation chamber and a dirt receptacle for receiving dirt and dust separated by the dirt separation chamber. A conduit connects the nozzle base to the housing. A suction source is located in one of the housing and the nozzle base. The suction source is in fluid communication with the dirt separation chamber. A generally conically shaped filter extends into the dirt separation chamber along a longitudinal axis of the dirt separation chamber.

Bagless stick type vacuum cleaner

An upright vacuum cleaner includes an upright housing section and a nozzle base section. A cyclonic airflow dirt and dust separating chamber is defined in the upright housing section. A suction source pulls air and entrained dirt, dust, and other contaminants through a main suction opening formed in the underside of the nozzle base section and into the cyclonic airflow chamber. The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container that defines the chamber. A main filter element filters residual contaminants from the suction airstream between the chamber and the suction source. An exhaust filter housing includes an airstream suction duct in fluid communication with an outlet of the airflow chamber and an inlet of the suction source. An outlet of the suction source is in fluid communication with an exhaust plenum of the exhaust filter housing. An exhaust filter is positioned radially outward of the exhaust plenum such that exhaust air is forcedly radially outward through the exhaust filter from the exhaust plenum to ensure that the air discharged into the atmosphere is contaminant free, including those contaminants introduced into the airstream by the suction source itself.

Upright vacuum cleaner with cyclonic airflow pathway

A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters the main suction opening, passes through the cyclonic chamber, and passes to an outlet of the suction source. Particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber. A main filter assembly is located in the cyclonic chamber so that a suction airstream moving from the main suction opening to the inlet of the suction source by way of the cyclonic airflow chamber passes through the filter medium thereof after the airstream moves in a cyclonic fashion within the cyclonic airflow chamber to remove residual particulates from the suction airstream before it leaves the cyclonic chamber.

A vacuum cleaner has a suction nozzle, a housing connected to the suction nozzle and a suction fan and motor assembly mounted to the housing. A dirt collecting receptacle is mounted to the housing and is in communication with the suction nozzle and suction fan and motor assembly. A support plate is pivotally mounted to the housing and selectively holds a cleaning sheet for collecting dust and debris from a surface to be cleaned.

Vacuum cleaner with cleaning pad

A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber. A main filter assembly, preferably including filter medium comprising polytetrafluoroethylene (PTFE), is located in the cyclonic chamber so that a suction airstream moving from the main suction opening to the inlet of said suction source by way of the cyclonic airflow chamber passes through the filter medium thereof after said airstream moves in a cyclonic fashion within the cyclonic airflow chamber to remove residual particulates from the suction airstream before it leaves the cyclonic chamber. A HEPA filter can be provided to filter the suction airstream exhausted through the outlet of the suction source prior to the airstream being discharged from the vacuum.
