The invention relates to a pool cleaning apparatus including: a cleaning unit (), at least one hydraulic system for circulating a liquid between at least one liquid inlet () and at least one liquid outlet () and through a filtration device of the cleaning unit (), a pump suitable for forcing the circulation of water between the liquid inlet () and the liquid outlet () and through the filtration device, drive and guide means for moving the cleaning unit, and means for controlling said drive and guide means. The pool cleaning apparatus includes at least one debris detection means placed in the hydraulic system of the cleaning unit ().

Pool cleaning apparatus with optimized control

The invention relates to a swimming-pool cleaning apparatus which comprises: a body; at least one hydraulic circuit for circulating liquid between at least one liquid intake and at least one liquid outlet, and through a filtering device of the cleaning apparatus; a fluid-circulation pump installed in the hydraulic circuit downstream from the filtering device; means for adjusting the pressure inside the hydraulic circuit upstream from the circulation pump, in response to a detected variation of said pressure, said pressure-adjustment means comprising: at least one secondary liquid intake () connected to the hydraulic circuit, upstream from the circulation pump, said at least one secondary liquid intake () being provided with a valve () mounted rotatably movable about an axis of rotation, and with means for driving the valve from an open position to a closed position, said means for driving the valve comprising a float (), the orientation and/or the force of which depend on the orientation of the cleaning apparatus relative to a horizontal plane.

Swimming-pool cleaning apparatus comprising means for adjusting the pressure inside said apparatus

The invention relates to swimming pool cleaning robot () comprising: a body (); at least one hydraulic circuit through which a liquid flows between at least one liquid inlet () and at least one liquid outlet (), said hydraulic circuit including at least one means for separating debris suspended in the liquid; pumping means for driving the liquid through the hydraulic circuit; means for driving and guiding the cleaning robot on a surface; and means for controlling the operating parameters of the means for driving and guiding the cleaning robot (). The control means comprise a pressure sensor () that can be used to determine the immersion depth of the cleaning robot in a swimming pool, and means for automatically controlling the measured pressure on the basis of a set value.

Swimming pool cleaning robot and method for using same

The invention relates to a method and device for modifying a device for cleaning a submerged surface, the device including a cleaning appliance, a control unit suitable for sending control signals to the appliance, characterized in that a modification device is inserted onto the link between the control unit and the appliance, which modification device includes an antenna for receiving wireless request signals and a signal-processing unit for transmitting signals from the control unit to the appliance and, upon receipt of wireless request signals in the receiving antenna, for ignoring signals from the control unit, and producing and transmitting priority control signals to the cleaning appliance.

Method and device for modifying a device for cleaning a submerged surface

Equipment and methods facilitating suitable orientation of salt-water chlorinators (SWCs) relative to the gravitational field of the Earth are detailed. So orienting an SWC in this manner reduces risk that the volume defined by its gas trap would not be accessible to hydrogen gas generated by the SWC in use. An accelerometer may be employed in connection with the SWC to assist in assessing orientation of the SWC relative to the gravitational field of the Earth.

Systems and methods of properly orienting pool and spa equipment

The invention relates to a method and device for modifying a device for cleaning a submerged surface, the device including a cleaning appliance, a control unit suitable control signals to the appliance, characterized in that a modification device is inserted onto the link between the control unit and the appliance, which modification device includes an antenna for receiving wireless request signals and a signal-processing unit for transmitting signals from the control unit to the appliance and, upon receipt of wireless request signals in the receiving antenna, for ignoring signals from the control unit, and producing and transmitting priority control signals to the cleaning appliance.

The invention concerns a device and a method of remotely controlling a motorized submerged surface cleaning apparatus () comprising a body and a drive device, said remote control device comprising a control terminal () having a housing, a device () for transmitting control signals for the drive device, characterized in that the housing comprises an orientation detector furnishing at least one orientation parameter of the housing, and in that said device comprises a unit for processing orientation parameters, producing a first command for the drive device for an orientation parameter that is within a first interval of values, and a second command for the drive device for an orientation parameter that is within a second predetermined interval of values.

Device for the remote control of a motorized underwater surface cleaning apparatus and apparatus thus controlled

The invention relates to a pool cleaning apparatus and a method for controlling such an apparatus comprising a body, a liquid inlet, a liquid outlet, a drive device, a pumping device, a hydraulic circuit between a liquid inlet and a pumping outlet and via a cleaning device, a monitoring device providing electronic signals which are representative of a state of the apparatus, an electronic signal processing unit receiving and analyzing the signals of the monitoring device and controlling the pumping device, wherein, on detection of a removal event of the body from the liquid, the processing unit stops the pumping device after a predetermined emptying time in order to allow active emptying of the hydraulic circuit.
