A dirt collection and separation module can include a suction air flow around the perimeter of a tank to ingest fine dust that becomes airborne during the emptying process. Additionally, a trash can suction nozzle around a rim, a hand vacuum docking station, and an auxiliary suction nozzle that can fluidly couple the hand vacuum.

A hand vacuum cleaner has a dual first stage cyclones.

An operating method of a station device for discharging dust from a cordless vacuum cleaner includes detecting occurrence of an event requesting discharging dust from a dustbin included in the cordless vacuum cleaner to the station device, and performing a dust discharge operation for discharging dust in the dustbin to a collector of the station device based on detecting of the occurrence of the event. The performing a dust discharge operation includes transmitting, to the cordless vacuum cleaner via short-range wireless communication, a control signal for operating a first suction motor of the cordless vacuum cleaner, and operating a second suction motor of the station device in cooperation with the first suction motor.

A cleaner includes a housing including a suction opening, a cyclone part configured to separate air and dust, and a dust bin configured to store dust separated from air in the cyclone part and a frame disposed to surround an axis of a cyclone flow of the cyclone part in the housing and configured to be movable between a first position and a second position in the housing, wherein the frame includes a first body disposed to face the suction opening at the first position and disposed to be inclined with respect to the axis of the cyclone flow, and an upper end of the first body is located to be the same as or higher than an upper end of the suction opening.

A vacuum collection vehicle may include a chassis, a vacuum container, a filter unit, a first discharge conduit and a second discharge conduit. The filter unit may include a filter housing that supports a filter independent of opposing interior walls. The vehicle may include a storage container supported by the chassis and containing a vacuum source or hose reel. The vehicle may include inner and outer collection receptacle supports for supporting collection receptacles within the vacuum container.

A filter device for a vacuum cleaner having a turbine device for generating at least one first and one second main air flow through at least a portion of the vacuum cleaner having and a control unit. The filter device has a first chamber including a first filter element, a first outflow opening, a first inlet opening and a first pressure surge element dividing the first chamber into a first chamber first space and a first chamber second space and reversibly movable between a first pressure surge element first position and a first pressure surge element second position, and a second chamber including a second filter element, a second outflow opening, a second inlet opening and a second pressure surge element dividing the second chamber into a second chamber first space and a second chamber second space reversibly movable between a second pressure surge element first position and a second pressure surge element second position.

A hand vacuum has a cyclone assembly which comprises a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber. The cyclone assembly comprises a stationary portion and an openable portion. The openable portion is rotatably mounted by a rotatable mount between a closed position in which the cyclone chamber and the dirt collection chamber are closed and an open position in which the cyclone chamber and the dirt collection chamber are open. The rotatable mount is located at a rearward end of the openable portion.

This document describes a mobile cleaning robot including a chassis having a forward portion and an aft portion; a blower affixed to the chassis; a bin supported by the chassis and configured to receive airflow from the blower, the chassis enabling evacuation of the bin through a bottom of the robot. The bin includes a top, a bottom, a sidewall, and an internal barrier. The bin includes a first volume and a second volume separated by the internal barrier and a filter unit supported by the internal barrier and removably disposed in an airflow path between the first volume that includes an intake port in the bin and the second volume that includes an exhaust port in the bin.
