ABSTRACT:
The VAC-BRUSH is a multi-functional apparatus used in the cleaning and vacuuming of gunite or marble plaster swimming pools. It can be used as a vacuum alone or in combination with a brush system ahead of the suction line thereby permitting the brushed particles to immediately be drawn into the filtration system and not into suspension.
