The invention relates to a swimming pool cleaning system comprising a cleaning apparatus to be immersed in the pool, the system further comprising at least one moving image acquisition means secured to a float via a flexible tie.

The present disclosure provides a cleaning method for the water surface of swimming pools and cleaning robot, the cleaning robot comprising a cleaning robot body, a sonar arranged around the cleaning robot body, two rear thrusters located at the tail of cleaning robot body. According to the present disclosure, as long as the cleaning robot body is placed on the water surface of the pool, cleaning robot body floating on the surface of the pool may automatically move and steer, so as to ensure that it can turn in advance before encountering the pool wall and won't knock against the pool wall, reduce the probability of malfunction and damaging of cleaning robot body, and the cleaning robot body can cover the entire water surface of pool and the pool wall, there is no omitting of cleaned water surface, and there is no need for excessive human involvement, it makes it easy for cleaning staffs to clean, when the cleaning robot body cleans the water surface of the pool, the cleaning staffs can carry out other cleaning work, which improved the cleaning efficiency of the cleaning staffs.

A method and an apparatus for cleaning a pool are provided, being applied to a client application installed in a terminal device. The method includes: modeling the pool according to information of the pool collected by the terminal device to determine a three-dimensional model of the pool; receiving a cleaning result on the pool sent by an unmanned cleaning device coupled with the terminal device, and displaying the cleaning result in the client application, wherein a cleaning route of the unmanned cleaning device is determined by the terminal device according to the three-dimensional model; and receiving feedback on the cleaning result, and adjusting a path planning of the unmanned cleaning device based on the feedback.

A swimming pool cleaning apparatus (10) may include a body (11), a hydraulic circuit for liquid circulation between a liquid inlet (13) and a liquid outlet (14) and through a filtration chamber (17), driving and guiding members (12) of the body on a submerged surface, and defining a guide plane (XY), and an adjustment mechanism (30) for the orientation of a liquid flow, disposed at the outlet of the liquid outlet. The adjustment mechanism is adapted to direct the flow of liquid that escapes from the liquid outlet in (at least) two predefined directions, one of which (33) corresponds to a first direction inclined with respect to the guide plane and the other of which (32) corresponds to a direction substantially perpendicular to the guide plane.

A pool cleaner including a housing, a driving assembly, a brush assembly, and a removable debris container. The removable debris container is coupled to the housing through a locking member in the brush assembly.

Automatic swimming pool cleaners (APCs) may include debris filters accessible from externally of the swimming pools in which the APCs are operating. The APCs may be programmed to climb to waterlines of the pools and present their debris filters above the waterlines for removal by users positioned outside the pools. Sensors may determine whether the filters have been reinstalled within the APCs, thus allowing the APCs to return to cleaning service.

Electrical connectors for automatic swimming pool cleaners (APCs) are described. The connectors may be positioned on, at, in, or near bodies of the APCs and configured to be submerged in water of swimming pools. They additionally may be designed to withstand mechanical pulling stresses when their associated electrical cables are pulled by users to remove APCs from the pools. If such a connector is separable, essentially the entirety of the electrical cable may be separated from the APC for purposes of untangling or storing the cable, as examples. The separation additionally may allow for insertion of one or more extension cables as needed or desired.

An automatic swimming pool cleaner (APC) may be used as a primary or sole water-circulation system of a pool or spa. The pool or spa hence need not employ dedicated water-circulation equipment, unlike conventional such vessels. In some cases, the APC includes a water treatment system for dispensing one or more chemicals for sanitizing (or otherwise treating) pool water.

Cleaning of a swimming pool may be facilitated by systems and methods for mapping a pool environment. Such mapping may occur in three dimensions when appropriate. At least some of the systems may include an apparatus for light detection and ranging (LIDAR) tethered to an automatic swimming pool cleaner.

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.
