Apparatus for cleaning a water-filled pool
First Claim
1. An apparatus for cleaning the bottom wall surface and the side wall surfaces of a water-filled pool, the apparatus comprising:
- a chassis;
propulsion means mounted on said chassis for propelling said chassis in the forward and rearward directions over said wall surfaces;
said chassis having a forward end transverse to said forward direction and a rearward end transverse to said rearward direction;
first and second brush roller units mounted on said chassis at said forward and rearward ends, respectively;
each of said brush roller units including;
a brush roller; and
, a pivot-arm assembly for pivotally connecting said brush roller to said chassis;
motor means for imparting rotation to said brush rollers so that said brush rollers counterrotate relative to each other whereby dirt particles on said surfaces are thrown toward the region beneath said chassis;
a filter; and
,a pump system communicating with said filter and being mounted on said chassis for generating a partial vacuum beneath said chassis whereby said dirt particles become entrained and are conducted from beneath said chassis to said filter where said dirt particles are trapped and clean water is returned to the pool.

Abstract
The invention is directed to an apparatus for cleaning the bottom and sides of a water-filled pool with an automatic pool cleaner equipped with motor-driven track belts (9a, 9b) and with a poolside programming module to control the cleaning method. The pool cleaner is equipped with two counter-rotating brush rollers (14a, 14b). Each brush roller is provided with a longitudinal shield (17a, 17b) which partly encloses the brush roller and is sealed against the pool cleaner chassis (1) to increase the water velocity generated by the pool cleaner pump impeller (4) thereby increasing the suction developed between the pool cleaner suction box (8) and the pool bottom or side walls, as applicable, to achieve more efficient cleaning and to ensure the travel of the pool cleaner, particularly along the side walls of the pool.
