Benefits of technology

[0012] In accordance with other aspects of the present invention, the robot may be provided with one or more measures to facilitate completion of its scanning operation within the time allowed by the batteries between charges. One of the above measures is that the robot may be pre-programmed to stop at or near a sidewall of the swimming pool, in order to facilitate easy removal of the robot from the pool, e.g. by means of its tail unit. The robot may be adapted to proceed to a wall and stop upon determining that either an abnormal or a normal pre-determined condition has been met.

Problems solved by technology

The most apparent is that the cord is susceptible to entanglement as the robot makes the turns and rotations associated with normal scanning of a pool.
However, a battery operated robot has the limitation that the time needed for the robot to finish the entire scanning procedure is limited to the time the battery can power it between charges.

Embodiment Construction

[0023]FIG. 1 shows an example of a robot 1 in accordance with one embodiment of the present invention. It comprises a robot body unit 10 and an optional tail unit 22. The robot body unit 10 comprises a battery pack 12, brushes 14, a drive means with a motor 16 and tracks 17 connecting the motor to the ends of the brushes 14, and a water outlet 19. Not seen in FIG. 1 are a water inlet, an impeller, a filter and a main controller, which are housed within a housing 18 of the robot and are known per se. The main controller may be a chip protected from exposure to water and comprising a memory and a processor. In addition, the robot comprises a handle 20 which contains two floats for maintaining a balanced position during use on a pool's floor, and a diagonal position when cleaning at the waterline. The battery pack 12 is enclosed within a sealed compartment.

[0024] During operation, the impeller draws water from the floor or sidewall of the pool via the water inlet through the filter. T...

Abstract

A cleaning robot for a swimming pool has a body unit with a battery power pack, adapted to move along the floor and / or walls of the pool. The robot may comprise a tail portion adapted for floating on the surface of the pool. The tail portion may have a float user interface. The robot may have a memory adapted to store a certain orientation of the robot and a controller to align the robot's orientation in accordance with the stored orientation. The robot may further be adapted to perform straight and stepped laps, to move in known mutually angled directions independently of the swimming pool's shape. The robot may perform a plurality of cleaning modes.

Description

FIELD OF THE INVENTION [0001] This invention relates to devices and methods for cleaning swimming pools, basins, and the like. More particularly, the invention relates to an automatic self-propelled cleaning robot powered by electrical rechargeable batteries. BACKGROUND OF THE INVENTION [0002] Battery powered pool cleaning robots are known in the art. They provide several advantages over robots that are powered via a power cable. The most apparent is that the cord is susceptible to entanglement as the robot makes the turns and rotations associated with normal scanning of a pool. [0003] However, a battery operated robot has the limitation that the time needed for the robot to finish the entire scanning procedure is limited to the time the battery can power it between charges. In a regular (rectangular) pool, scanning the pool's floor is often performed according to the following algorithm: a robot traverses the pool floor until first encountering a sidewall; it then retreats from the...
