Cleaning your spa filter has never been easier with the Spa Filter Cleaning Brush. The power flush spray nozzle was specifically designed to make the task of cleaning your spa filter quick, simple and effective. Simply attach a standard garden hose (not included) to the nozzle and squeeze the trigger. The brush head bristles easily penetrate into each of the pleats of the filter loosening debris while the pressure nozzle directs the water deep into the filter flushing out any additional trapped debris.
