A surface cleaning apparatus comprises an air treatment member having an air treatment chamber. A moveable member is positioned in the air treatment chamber. A driving assembly is drivingly connected to the moveable member wherein the driving assembly is operable between a stored position is which the surface cleaning apparatus is operable to clean a surface and a cleaned position in which the moveable member has been translated through at least a portion of the chamber, wherein, in the stored position, a portion of the driving assembly is longitudinally spaced from the first and second axially spaced apart ends of the air treatment chamber.

A system and method are provided in at least one embodiment to process water to produce gas that can be separated into at least two gas flows using a water treatment system having a disk-pack rotating in it to cause out gassing from the water. In a further embodiment, the method and system use the gas released from the water to produce substantially fresh water from the processed salt water.

A surface cleaning apparatus comprises an air treatment chamber having a first end, an axially opposed second end, an axis extending between the first and second axially opposed ends and an axially extending air treatment chamber sidewall. The air treatment chamber air outlet is provided at the second opposed end and the first opposed end is moveably mounted between a closed position and an open position in which the air treatment chamber is open. The air treatment chamber has a stationary portion and an openable portion and the openable portion is moveably mounted between a closed position and an open position in which the air treatment chamber is open. When the openable portion is in the closed position, the openable portion and the stationery portion abut along peripheral edges that extend along a length of the air treatment chamber sidewall.

An improved modular hydrocyclone and method of operating for centrifugal cleaning fluid wherein the hydrocyclone has a plurality of inserts each of different sizes and configurations for selectively and interchangeably inserting into the modular body thereby adjusting capacity and cleaning efficiency of the hydrocyclone without changing out the body. One or more embodiments relate to systems and methods for utilizing a hydrocyclone system with interchangeable components.

A surface cleaning apparatus comprises an air treatment chamber having a first end comprising a first end wall, an axially spaced apart second end comprising a second end wall, a sidewall extending between the first and second end walls, an air treatment chamber air inlet and an air treatment chamber air outlet provided at the second end. A dirt collection region, which is contiguous with the air treatment chamber, is positioned axially from the first and second end walls and is closer to the second end wall than the first end wall.

A separating device that receives via a lower inlet an air flow laden with impurities, namely dust produced by pads of a brake assembly, and makes it possible to separate and collect heavy dust. The housing of the device contains a multi-cyclone cluster, with cyclones distributed annularly and supplied tangentially by a central collector surmounting an axial duct communicating with the inlet. The centrifuged and separated liquid and solid particles are directly collected below the cyclones in a trapping zone around the duct, the cluster forming a transverse barrier connected in a sealed manner to the duct so as to prevent the liquid collected in the trapping zone from rising towards a downstream zone, only gravity discharge orifices of the cyclones allowing the trapping zone to be filled during the operation of the device.
