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 pool cleaner includes a vent mechanism and a water port in fluid communication with the vent mechanism. When a forward end of the pool cleaner extends above a waterline of the pool, water flows through the vent mechanism and the water port over an inlet port and prevents loss of suction at the inlet port. A protruding member of the pool cleaner contacts submerged obstacle and tilts the pool cleaner to prevent the pool cleaner from becoming stuck on the submerged obstacle.

An integrated process and system for the cleaning of any body of water in need of periodic cleaning, including but not limited to a swimming pool or spa. A submersible water filtration apparatus comprises a housing unit, an impeller driven by an electric motor powered by batteries, an inlet where fluid, such as water, is drawn inwards into the submersible water filtration apparatus, an outlet for returning filtered water into the body of water, and at least one filter zone.

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.

An apparatus for cleaning a body of water includes a housing defining an interior passageway, with a mesh catch bag connected at the upper end of the inner passage. A power source and a submersible pump are electrically connected, and both connect to the housing. The pump draws water from the body of water, and directs it to a plurality of openings oriented on an inner surface of the housing. The openings direct water upwardly through the inner passage of the housing and through the catch bag, thereby drawing debris from beneath the housing upwardly through the housing and into the catch bag.

A pool cleaner includes a vent mechanism and a water port in fluid communication with the vent mechanism. When a forward end of the pool cleaner extends above a waterline of the pool, water flows through the vent mechanism and the water port over an inlet port and prevents loss of suction at the inlet port. A protruding member of the pool cleaner contacts submerged obstacle and tilts the pool cleaner to prevent the pool cleaner from becoming stuck on the submerged obstacle.

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.

A pool cleaner equipped with a rotating brush assembly is disclosed. The brush assembly is removably coupled to the pool cleaner using clamps that are readily accessible, supported by the pool cleaner, and operable by hand. The clamps may be manipulated between a ready configuration, a loaded configuration to receive a brush assembly, and a locked configuration to secure the brush assembly.

The present application provides a floating device and a robotic pool cleaner, which relate to the technical field of swimming pool cleaning. the floating device has a wireless communication function, so that instructions can be transmitted to the wireless transmission module remotely through a remote controller, thereby controlling the walking and working status of the cleaning device of the robotic pool cleaner, which can realize intelligent cleaning path planning, and can also know the working position and working status of the robotic pool cleaner in time, which greatly improves the convenience of use and cleaning efficiency.

The invention relates to an underwater cleaner, in particular for a swimming pool, with a housing in which in particular a battery-powered pump with an electric motor and an impeller rotatable about an impeller axis of rotation is arranged, with a suction nozzle—defining a suction plane—formed by the housing, and a flow channel which is arranged in the housing and accommodates the impeller, is designed to be inclined with respect to the suction plane and which extends between an inlet opening arranged in the region of the suction nozzle and an outlet opening, wherein a receptacle for a filter device is arranged in the region of the outlet opening, and wherein the housing together with the suction nozzle can be manufactured by injection molding and the flow channel can be molded by a slider which can be pulled in the longitudinal direction of the flow channel.
