A floating liquid intake for a liquid suction removal system, the liquid intake comprising housing defining an internal cavity. The housing has a hollow and buoyant annular body, an upper cover and a lower cover. The internal cavity is formed between the upper and lower covers. A substantially annular inlet is formed in the annular body for ingress of liquid into the cavity. The annular body has a buoyancy sufficient for the liquid intake to float in a liquid with the annular inlet submerged below the surface of the liquid in which the liquid intake is floating. A pipe extends into the cavity and the pipe includes an inlet that in use is open below the surface of the liquid within the cavity. The pipe extends outside of the cavity for connection to a liquid suction removal system.

A pool cleaning robot as substantially illustrated in the specification. A method as substantially illustrated in the specification.

Systems and methods can support an autonomous pool skimming system. The pool skimming system may have a body with two or more hulls. Two or more paddlewheels may be coupled to the body. An independent motor may drive each paddlewheel. The motors may be independently controllable to support steering. The pool skimming system may have one or more processing units, two or more distance sensors, one or more solar cells, and a power supply operable to power the processing units and the motors from energy supplied by the solar cells. One or more processing modules may configure the processing units to plan and execute a traversal path across the surface of a body of water, such as a swimming pool, to collect debris into a removable basket. A portion of the traversal path may be established according to signals from distance sensors.

A sanitation device for cleaning a body of water in an immersion pool of a mikvah has a hollow member that extends along an axis X. In an operative position suitable for cleaning the device is arranged to extend generally immersed in the water and in a general upright orientation. The device further has an upper opening that in the operative position is arranged to be generally flush with the upper surface of the water and a propeller arranged to rotate about axis X and located at a lower region of the device that is arranged to form a downward flow that urges water to enter the device via the upper opening of the device.

A smart pool skimmer is disclosed. In one embodiment, the pool skimmer includes a body housing having electronics and sensors extending from the body housing to monitor pool conditions. The sensors detect a plurality of pool condition, including but not limited to pH, ORP, temperature, water level, water movement, chlorine levels, and salt concentration. The smart pool skimmer receives data from the sensors and sends the information to a user computing device or a cloud-based analytics server, which tracks conditions of the pool water. A solar panel may be provided on the housing to enable the smart skimmer to run on renewable energy. Additionally, visual light indicators can be mounted on top of the cover plate to provide visual indications of pool conditions.

A powered or non-powered pool skimmer device can include a funnel assembly comprising a funnel having a wide opening and a narrow opening, and a funnel profile extending between the wide opening and the narrow opening, a funnel plate to allow the funnel to freely float or be manually adjusted to position the funnel just beneath the water surface, a filter assembly positioned below the funnel assembly, and a main body with no bottom, so water can flow freely into the swimming pool's main filter system, that fits into an existing skimmer in both height and diameter extending along an axis, which can be locked into the skimmer via a skimmer adapter ring, wherein the funnel assembly, the filter assembly, and the pump assembly are positioned within the main body and arranged along the axis.

A floatation accessory for a pool vacuum is an apparatus that maintains an inverted position for a pool vacuum such that the mouth of the pool vacuum suctions debris along the surface of a pool. The apparatus includes a support platform, a first float, a second float, a support ridge, a handle, an elongated guard, and a suspension system. The support platform upholds the first float and the second float. The first float and the second float are used to float a pool vacuum that is engaged with the apparatus. The support ridge connects the first float and the second float and offsets the elongated guard from the mouth of a pool vacuum. The elongated guard offsets the mouth of a pool vacuum from the side walls of a pool. The suspension system loops a pool vacuum with the support platform, and consequently the first float and the second float.

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.

A floating water jet for spraying chlorinated water at water surface of a pool is disclosed herein. The floating water jet includes a cylindrical body having a closed end and an open end, an internal wall within the cylindrical body defining a sealed air chamber within the cylindrical body adjacent the closed end, the sealed chamber providing buoyancy to the cylindrical body such that the cylindrical body floats on the water surface of the pool with a longitudinal axis of the cylindrical body being parallel to the water surface. An internal chamber is provided within the cylindrical body between the open end and the internal wall for receiving the chlorinated water. An end wall is sealed to the open end, the end wall including a central inlet opening adapted for connection to an outlet end of a floating pool hose, and a plurality of outlet openings in the end wall arranged concentrically about the central opening. Chlorinated water from the pool hose is directed into the internal chamber via the central inlet opening and exits the internal chamber via the plurality of outlet openings to direct jets of the chlorinated water in a direction parallel to the water surface.
