A reconfigurable vacuum attachment may include a bell-shaped housing. The bell-shaped housing may have a bell-opening and a hose-interface. The hose-interface may be configured to hydraulically couple with a vacuum hose. A skimmer-plate may be attachable to the bell-opening and include a skimmer-aperture extending through the skimmer-plate. The reconfigurable vacuum attachment may further include a removable brush assembly. The brush assembly may host a rotatable brush coupled to a brush driver. The brush driver may be configured to hydraulically couple with the vacuum hose and convert water flow into a torque and spin the bristles. A buoy may be attached to the housing allowing the reconfigurable vacuum attachment to be used as a pool skimmer. The reconfigurable vacuum attachment is useful for skimming a pool surface and dislodging and vacuuming matter from a pool wall.

A hand-held turbine cleaning tool includes front and rear housings coupled to each other, an outlet at one end of the tool, and a top of the tool at an opposed end. The outlet is directed in a first direction away from the top. An inlet is disposed between the outlet and the top and is also directed in the first direction. A diverter valve at the inlet is moveable between on and off positions. The on position directs water flowing into the inlet from the inlet, up to the top in a second direction opposite the first direction, and then down to the outlet in the first direction. A turbine at the top has a turbine shaft that extends outside the tool. An abrasive member is connected to the turbine shaft and is configured to rotate when water flows from the inlet to the outlet.

The invention relates to a device for guiding a cable for linking a submerged robot, in particular a robot for cleaning swimming pools, to the device for controlling and powering same, said guiding device comprising: a. a coupling including a rotary connector, connected by one side to a first floating portion of the linking cable extending from the control and power device to said coupling and, by the other side, to a second portion of the linking cable extending from said coupling to the submerged robot; b. a floating mounting including: bi. a float; bii. an interface for mechanically linking the rotary connector to said float; and biii. a hood extending above the surface when the floating mounting is submerged in a liquid and removably connected to the float; c. in which the mechanical link between the float and the rotary coupling is a ball-and-socket link.

The present invention provides a structure for assembling and disassembling a dirt suction head to/from a filter bag, comprising a first connection piece and a second connection piece; one end of the second connection piece is detachably connected to a connection pipe of the dirt suction head, and the other end of the second connection piece is provided with a holding cavity; one end of the first connection piece is connected to an opening of an end of a filter bag body, and the other end of the first connection piece is assembled into the holding cavity; or a circumferential side edge of the opening of the filter bag body is tightly pressed and fixed between an outer side wall of the first connection piece and an inner side wall of the holding cavity, which has achieved a quick assembling and disassembling and smooth external aesthetics of a connection position.

Debris filters for automatic swimming pool cleaners may be formed of metal, carbon fibers, or composites more rigid than soft nylon bags. In at least one version, the filter may be made of, or include, steel or stainless steel. Non-uniform sizes, densities, and/or shapes of openings in the filtration material may be created to provide different levels of filtration in a single device.

Improved flow control valve assemblies for fluid systems (e.g., pools or spas) are provided. Advantageous flow control valve assemblies for pool/spa cleaners (e.g., suction pool/spa cleaners) are provided. The present disclosure provides for flow control assemblies for suction pool/spa cleaners, with the cleaners utilized in conjunction with a variable speed pump. A manual valve set-up can be removed from the system, and an advantageous flow control valve assembly can be provided to automatically regulate the flow/suction to the cleaner. The improved flow control valve assembly thereby provides regulated flow to the cleaner, so that if the cleaner remains in the water at low pump speeds, when the pump is later operated at a higher speed the cleaner will function as designed. When there is flow/suction below the desired operating parameters of the cleaner, the pump will operate as desired, and the cleaner is stationary.

A vacuum head comprising an outer shell having a lower ventral wall and an upper dorsal wall, a harness attached to the dorsal wall, a base brush extending downward from the ventral wall, an inlet positioned at an anterior end of the outer shell, an outlet positioned at a posterior end of the outer shell, and an inner channel fluidly connecting the inlet to the outlet.

A hot tub vacuum attachment apparatus for cleaning debris from a hot tub utilizing the integrated pump system includes an attachment head to selectively engage a filter housing of a hot tub or pool. A tubular stem has a stem outlet end coupled to, and in fluid communication with, the attachment head. A filter mount is coupled to the tubular stem. The filter mount has an output end coupled to a stem inlet end of the tubular stem, an input end, and a filter receiver coupled between the output end and the input end. A filter system is coupled the filter receiver of the filter mount. All fluid flowing from the input end to the output end passes through the filter system to collect particles and debris. A flexible hose has a hose proximal end coupled to the input end of the filter mount and a hose distal end.

Methods and apparatus are disclosed for an improved underwater vacuum cleaning system. Urging elements are provided on a vacuum head to encourage debris, especially large pieces of underwater debris, to matriculate under the head or otherwise toward the vacuum opening, rather than traveling over the head or otherwise NOT toward the vacuum opening. Various embodiments of engagement elements are disclosed between the vacuum head and a vacuum hose to improve the connection therebetween.
