A surface cleaning apparatus including an air treatment unit, a refuse unit, and a flexible hose. The air treatment unit includes an air flow path from a dirty air inlet to a clean air outlet and an air treatment member comprising an air treatment chamber and a dirt collection region having an emptying door which is operable between a closed position and an open position. The flexible hose is removably connectable to the dirty air inlet. The air treatment unit is operable in a first operating mode in which the air treatment member is in air flow communication with the dirty air inlet and the emptying door is closed. The air treatment unit is operable in a second operating mode in which air flow through the air treatment member is terminated and the emptying door is open whereby dirt is transferable to a refuse container of the refuse unit.

A water collector includes a metallic center body, an outer guide disposed concentrically within the metallic center body, a mid guide disposed concentrically within the outer guide, and an inner guide disposed concentrically within the mid guide. The outer guide, the mid guide, and the inner guide are formed from a non-metallic material.

Provided is a gas-liquid separator that can achieve separation of water from water-containing gas while reducing pressure loss in a gas-liquid separation section. The gas-liquid separator includes: a housing having a water storage space in a bottom portion; an inlet port that is connected to the housing and through which the water-containing gas is introduced; a sloping guide section that guides the water-containing gas supplied through the inlet port into the housing in an upward direction above the water storage space; and a separation plate including a comb-like contact surface configured in such a way as to separate water contained in the water-containing gas guided by the sloping guide section by coming into contact with the water-containing gas.

Z-filters capable of cleaning particulate matter from airflow streams in dust collectors, including reverse flow, reverse air, and reverse pulse systems.

A cleaner including a cyclone dust collector is disclosed. The cleaner includes a dust collector configured to separate dust from air through centrifugation. The dust collector includes: a dust collection case having an inlet through which air is introduced and an outlet through which the air is discharged; and at least one dust separator arranged to separate dust from the air introduced through the inlet. A cleaning member is provided in the at least one dust separator such that the cleaning member cleans at least a portion of an inner wall of the at least one dust separator.

The invention creates a dust collector having a container through which the dirty air passes. The container includes an inlet for acceptance of dirty air and an outlet for exhaustion of clean air. In the preferred embodiment, between the inlet and outlet is a serpentine pathway into which a fogging apparatus emits a fog of water to capture dust particles in the air passing therethrough. An alternative embodiment passes a dirty airflow through the fog while creating turbulence within the airflow to enhance contact between the fog and dirt particles.

A portable multiuse home station for a first vacuum cleaner and a second vacuum cleaner that is operable independently of the first vacuum cleaner. The multiuse home station is positionable in a room of a building and comprises a housing that is distinct from the room. The portable multiuse home station further comprising an additional component that provides an additional functionality to the portable multiuse home station.
