Detailed is 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 including: 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: b(i). a float; b(ii). an interface for mechanically linking the rotary connector to said float; and b(iii). 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.

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.

A pool cleaner water surface diverter 7 that will break the pool water surface 1 before the pool cleaner 4 reaches the surface, or at least before the suction of the cleaner 4 is able to suck in air. A rim 12 extends beyond a physical envelope of the cleaner, such as being wider than is the cleaner. Ideally the diverter has neutral or near neutral buoyancy in the pool water. A central hub on a pool hose 5 allows rotation of the diverter relative to the hose. compartments/containers may contain a substantially buoyancy neutral fluid or material in water e.g. PVA foam.

A pool cleaner including a turbine assembly, a timer assembly, and a scrubber assembly. The timer assembly is configured to rotate the turbine assembly in a first direction and a second direction. The scrubber assembly is configured to rotate in a forward direction when the turbine assembly rotates in the first direction, and to rotate in a rearward direction when the turbine assembly rotates in the second direction.

The invention relates to a power lead for a swimming pool cleaning robot. Said power lead comprises a rotary connector and a buoyancy means supporting said rotary connector. An upper part of said buoyancy means is a cap shaped to slide under a swimming pool cover, under the effect of a traction exerted by the swimming pool cleaning robot on the buoyancy means through the power lead.

Embodiments of the invention provide a scrubber assembly for a pool cleaner comprising a center shaft and a rotary cylinder positioned around the center shaft and including an internal spur gear profile. The scrubber assembly further includes a first pinion gear engagable with the internal spur gear profile of the rotary cylinder and aligned off-center from the center shaft and a first end bracket coupled to a first end of the center shaft and rotatable about the first pinion gear.

A pool cleaner assembly includes a pool cleaner body supported for motion over an underwater pool surface, the pool cleaner body defining a water source connection and a suction opening on a lower surface thereof through which debris is removed from the underwater pool surface. The assembly further includes a steering device having a first steering device end configured for connection to a water hose and a second steering device end connected to the water source connection of the pool cleaner body, the steering device being operable to generate relative rotational motion between the first and second steering device ends.

A non-chemical sanitation system for a body of water comprises a floating base, an internal hydro-electric power generator, and one or more sanitizing mechanisms electrically powered by the hydro-electric power generator, where the hydro-electric power generator derives its energy from water pressure produced by a pool pump. In some embodiments, the one or more non-chemical sanitizing mechanisms comprise one or more ultraviolet LED lights. In some embodiments, the one or more non-chemical sanitizing mechanisms comprise one or more ionizers. In some embodiments, the system is connected to a filter pipe and filter of a pool and the hydro-electric power generator is placed within the path of water flowing to the pool filter in order to generate power and power the one or more sanitizing mechanisms.

An adapter for a pool cleaning system is provided. The adapter includes a base member having a top and a bottom surface. The adapter also includes six upper ports coupled to the top surface of the base member, each upper port including an upper aperture extending through the upper port and through the base member. The adapter further includes five lower ports coupled to the bottom surface of the base member, each lower port including a lower aperture extending through the lower port and through the base member. In some embodiments, four of lower ports are in fluid communication four of the upper ports and one of the lower ports is in fluid communication with two of the upper ports.

A hose adapter for use in an automated pool cleaning system is provided. The adapter attaches at one end to the outlet of a dedicated water return line in a swimming pool and at an opposite end to a pool cleaner hose. The adapter has an extension arm that secures the hose at an elevated position above the water return line. By elevating the hose, the adapter prevents kinking and tangling in the hose so that the automated cleaning system operates more effectively.
