Pressure pool cleaners operate by the pressure of your pool return (Polaris 65/165 and 360), or from the power of a booster pump (Polaris 380/3900 and Letro). The water pressure entering the cleaner powers the drive train, the venturi jets and the sweep tail. Pressure cleaners are loved by millions for their power, speed and cleaning ability, although the price to retrofit a booster pump cleaner is often prohibitive.
Pressure pool cleaners, also known as Booster pump powered, are powered by a separate booster pump that sits by your pool pump. This makes this class of pool cleaners fully automatic, because the booster pump can be operated on a timeclock, turning itself (and the cleaner) on and off at specified times. Other cleaners will run whenever the filter pump is running, increasing wear and tear on the pool cleaner parts. Pressure-side automatic pool cleaners are powered by water pressure and feature internal vacuum bags. These cleaners attach to the pressure side (return) of your pool's circulation system,have their own hydraulic power plant, and are propelled by the water that is pumped or "pushed" back to the pool. Being on the pressure side, these units have distinct advantages. They are helpful in distributing clean filtered water around the pool and having their own debris bag means that they don't compromise the filter system by bringing dirt and debris into the pump basket and pool filter. Even with the bag full, a pressure cleaner still operates, stirring debris up; it just won't suck up much more debris until the bag is emptied.
