Pool cleaner with brush

Abstract

A pool cleaner device is configured to travel along an enclosing surface of a pool. The device includes at least one elongated brush having a long axis that is oriented at a nonzero angle to a lateral axis of the device and substantially parallel to the surface when the pool cleaner is traveling along the surface. The device also includes a mechanism for causing bristles of the elongated brush to vibrate against the surface when the device is operating on that surface.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority from Israel application No. 214419 filed on Aug. 2, 2011, incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to pool cleaners. More particularly, the present invention relates to a pool cleaner with a brush.BACKGROUND OF THE INVENTION[0003]Swimming pools require frequent cleaning, often on a daily basis. Thus, autonomous devices for cleaning swimming pools often present an attractive alternative to manual cleaning. The use of electrically powered robotic swimming pool cleaners is a common method of cleaning dirt and debris from the bottom and sides of such pools.[0004]Robotic swimming pool cleaners have been described, for example, by Gard in US 2007 / 0028405. A robotic pool cleaner typically includes a drive motor and rollers, wheels, or tracks for locomotion. A robotic pool cleaner also typically includes a pump for drawing water through a fil...

AI Technical Summary

Benefits of technology

The invention is a brush for a robotic pool cleaner that is designed to effectively remove dirt from the walls and waterline of a swimming pool. The technical effect of this brush is to improve the cleaning performance of the robot pool cleaner.

Problems solved by technology

These cleaners operate on the principle of lifting debris from the floor of the pool by suction and typically can only remove loose particles.

Thus any dirt that is found on the pool walls, typically oil-bound or of a biological nature, is often firmly attached to the surface and thus cannot be removed by suction alone.

The rotating action of a typical cleaner's brushes is generally insufficient to remove much of this dirt.

Such passive pushing would be unlikely to remove any debris other than loose particles.

Such brushes or elements do not generally impart sufficient scrubbing action to remove dirt or biological debris which has firmly adhered to the walls or vertical surfaces of a swimming pool.

Furthermore, during normal programmed movement of the pool cleaner, the brushes do not reach the waterline.
