Cleaning your filter no longer has to be a messy, dreaded chore. The Blaster 2000 is completely automatic! Just connect a garden hose, set the filter on, turn on the water and it does all the work. The Blaster rotates your filter while power cleaning jets spray focused water under pressure, deep inside the filter pleats. As your spa or pool cartridge is slowly turning, dirt and debris will be blasted from the filter in no time at all. X-Large - 31" x 12" x 6" fits filters up to 34" in length.
