A suction head for submersible use in the water of an artificial pool. The suction head having a body provided with a suction duct and a suction pump placed inside the suction duct. The suction pump includes an electric motor coupled to a propeller. The rotation of the propeller producing suction along the suction duct between a suction mouth and an upper opening of the duct. The suction head further includes a central deflector placed between the motor and the propeller so as to prevent bulky debris from piling up below the propeller and discharging it to the periphery of the suction duct.

A method for charging a pool cleaning robot, the method may include positioning a first wireless charging element of a pool cleaning robot within a charging range of a second wireless charging element of a floating unit; wherein the floating unit is electrically and mechanically coupled to an external power source, wherein the positioning comprises moving at least one of the pool cleaning robot and the floating unit; and wirelessly charging, by the second wireless charging element, the first wireless charging element, wherein the charging occurs while maintaining the first wireless charging element within the charging range of the floating unit, despite movements of the floating unit.

A swimming pool cleaner coupled to a hose, wherein the hose is configured to automatically extend and retract

A pool cleaner for use in a pool may include a housing, a driving assembly, a traction assembly, and a filtration assembly. The driving assembly may include an inlet conduit configured to receive pressurized water, an impeller in fluid communication with the inlet conduit, an outlet conduit in fluid communication with the impeller, and an outlet nozzle coupled to the outlet conduit and may be configured to eject the pressurized water upward from the housing and into the pool in a parallel or oblique ejection direction relative to a vertical axis. The traction assembly may be coupled to the impeller to drive the housing across the pool and the filtration assembly may be configured to filter water from the pool.

A top-bottom pool cleaner is provided including a top housing and a nose attached to the top housing. The top housing including an exterior surface and a top surface having a filter. The nose defines a chamber for receiving and retaining water within the nose. The chamber of the nose receives water through the filter when the cleaner is submerged and retains water within the chamber when the cleaner reaches a top surface of the water from under the water surface, the retention of the water within the nose preventing the pool cleaner from oscillating above and below the top surface of the water.

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 underwater station may include a filter manipulator that is arranged to input a filter into a pool cleaning robot that is located in a filter replacement position and to assist in positioning the filter at a filtering position in which the filter is at least partially disposed within a fluid path formed between a first fluid opening and a second fluid opening of the housing thereby allowing the filter to apply a filtering operation on fluid that passes through the fluid path.

A method of controlling a liquid movement system, such as a pool system. The method includes receiving a maximum time that an auxiliary load is to operate, receiving a minimum pump speed of a pump system that pumps a liquid through the auxiliary load, monitoring the time that an auxiliary load has been in operation, monitoring the pump speed of a pump system that pumps a liquid through the auxiliary load, and deactivating the auxiliary load if the maximum time or minimum pump speed has been met. Also disclosed are a pool system and a controller for controlling the pool system.

A fluid distribution system for an underwater pool cleaner comprises an inlet body having an inlet for receiving a supply of pressurized fluid, a valve assembly body in fluid communication with the inlet of the inlet body and including a plurality of fluid outlets, a first one of the outlets provides fluid for propelling the underwater pool cleaner in a forward direction and a second one of the outlets provides fluid for propelling the underwater pool cleaner in a reverse direction, and a valve subassembly including a cam wheel that is fluidicly driven by the supply of pressurized fluid and periodically switches the supply of pressurized fluid from the first one of the outlets to the second one of the outlets to periodically change direction of propulsion of the underwater pool cleaner.

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.
