A surface cleaning apparatus such as an extractor has a liquid delivery system, a separator, a collection chamber in communication a the separated element outlet of the separator, and a separated liquid collection container downstream from the collection chamber.

A pool strainer basket insert system and method are contemplated in which a high porosity, coarse fibrous mass is inserted in a pool skimmer basket. Via optimization of the material properties of the fibrous mass and configuration such that approximately 50% of the fibrous mass is located above the waterline and 50% below the water line the problems of the prior art may be solved via the retaining properties of the fibrous mass, enabling insects and small organic matter to be retained and preventing their migration back to the main body of the pool.

An upright extractor has an upright section moveably mounted to a surface cleaning head. The upright section has a wand and hose assembly and a liquid separator. The liquid separator comprises a solid collection chamber that is separated from a liquid collection chamber by a porous divider. The upright extractor is operable in a floor cleaning mode in which the handle is a driving handle of the upright extractor. The upright extractor is also operable in an above floor cleaning mode in which the inlet end of the wand is disconnected from fluid flow communication with the surface cleaning head dirty fluid inlet and an above floor air flow path extends from the inlet end of the wand to the clean air outlet and the liquid separator and the suction motor are provided in the above floor cleaning air flow path.

A filter device is formed by installing an orifice member to the fluid passage of a filter body and avoids being functionally impaired by residue such as shavings generated during the installing of the orifice member. A filter device is provided with a filter body that has a fluid passage; and an orifice member that is installed in the fluid passage. The orifice member is provided with a body that has an orifice, a first flange that is press-fitted into the large-diameter part of the fluid passage, and a second flange that forms a closed trap space between itself and the first flange. A knurling is provided to the outer peripheral surface of the first flange. A knurling is provided to the outer peripheral surface of the first flange. Shavings formed during the installing of the orifice member to the filter body are captured in the trap space.

A filter extractor may include a first gutter fixed to a tool body and a second gutter being pivotably connected to the tool body. Additionally, a lifting device may be provided on the filter extractor. The lifting device is configured to extend and retract a line through the first gutter and the second gutter to extract a filter from a fluid conduit.

A water treatment insert for a pool skimmer system includes a chemical treatment portion separated from a mechanical filtration portion. The treatment device includes an upper portion and a lower portion. The upper section can include a vertical wall or walls, which should be substantially watertight so that substantially all the water entering the pool skimmer flows through the upper portion, and then into the lower section. The entire device is preferably received in the filter basket receiving section of a conventional pool skimmer, in place of the conventional filter basket. One of the upper and lower sections provides mechanical filtration and the other chemical treatment, to enhance the water treatment function of the skimmer.

A solids interceptor and methods of using the same. The solids interceptor includes a tank including an open end, a wastewater inlet, and one or more wastewater outlets. A basket assembly is removably attachable to the tank via the open end between an operable position and a removed position. The basket assembly may seal the open end when in the operable position and expose the open end of the tank to a surrounding environment when in the removed position. A first and second outlet may extend away from an interior of the tank in a first and direction, respectively, with the second direction being oriented at an angle with respect to the first direction. The basket assembly may include a seal that is compressed about a circumferentially extending corner provided on the tank to thereby seal the open end of the tank and the plumbing system.

A filtering system capable of removing particulates from a water slurry is disclosed. The filtering system comprises a base plate, the base plate comprising a sealing surface and a slurry inlet. A flexible vessel is configured to seal to the sealing surface, and an interior cavity, wherein the flexible vessel is formed of a flexible filtering material capable of retaining particulates. The flexible vessel permits liquid entering through the slurry inlet to pass through the filtering material and is capable of withstanding an internal pressure sufficient to form a particulate cake without rupturing the flexible vessel. A sealing system is provided for retaining an upper portion of the flexible vessel against the sealing surface. The filtering system may be part of a portable system that includes a cart, hoses, piping, a pneumatic pump and a control panel.
