Abstract
The invention relates to a pool cleaning apparatus including: a cleaning unit (100), at least one hydraulic system for circulating a liquid between at least one liquid inlet (103) and at least one liquid outlet (104) and through a filtration device of the cleaning unit (100), a pump suitable for forcing the circulation of water between the liquid inlet (103) and the liquid outlet (104) 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 (100).
Claims16
A swimming pool cleaner for a swimming pool or spa, the swimming pool cleaner comprising:
- a body comprising at least one inlet and at least one outlet;
- a pump within the body;
- a filter within the body, wherein a hydraulic circuit through the body is from the at least one inlet, through the filter, and to the at least one outlet;
- at least one sensor for detecting debris in the hydraulic circuit;
- and
- a control unit configured to:
- determine at least one of an upper threshold or a lower threshold level of debris;
- compare debris data from the at least one sensor relative to the determined upper threshold level or lower threshold level;
- and
- generate an output response based on the comparison.
A swimming pool cleaner for a swimming pool or spa, the swimming pool cleaner comprising:
- a hydraulic circuit comprising a water inlet and a water outlet;
- at least one sensor configured to detect debris in the water outlet of the hydraulic circuit of the swimming pool cleaner;
- and
- a control system configured to modify a cleaning pattern responsive to the detection of the debris by the at least one sensor and generate a control response responsive to the detection of the debris by the at least one sensor.
A method of controlling a swimming pool cleaner, the method comprising:
- determining a normal level of debris in a pool or spa using the swimming pool cleaner;
- determining at least one of an upper threshold level or a lower threshold level of debris based on the determined normal level of debris;
- and
- collecting debris from the pool or spa using the swimming pool cleaner and characterizing the debris collected using a sensor within the swimming pool cleaner relative to the determined upper threshold level or lower threshold level.
