Suction Side Cleaners: All Pool Types
These are cleaners that attach to the suction side of your plumbing. The suction side refers to the pipes and fittings that bring water out of the pool to be filtered; that water which is being “sucked” out of the pool by the filter pump. Usually this is the pool skimmer, and you attach the hose from the cleaner into the hole in the skimmer beneath the basket, or use a skimvac attachment and it vacuums into your skimmer basket. Some pools have a dedicated suction cleaner line, a nice luxury to have. In these cases, you attach the cleaner directly to a wall fitting, usually located in the middle of the long side of the pool.
Suction pool cleaners include the Hayward PoolVac Ultra, Navigator, Aquabug, Kreepy Krauly, E-Z Vac, Baracuda Ranger, G3, Polaris 150, and ATV. Please visit our Swimming pool cleaners page for a complete list of suction side cleaners. These are divided in roughly two types, the flat, round disk or pulse type cleaner, and the hydro drive train powered types like the Polaris ATV and the Hayward Navigator style cleaners.
With the hose attached and the filter pump running, suction is created on the underside of the cleaner. The cleaner moves randomly, or automatically around the pool with motion created by a device that gives a stop/ start pulsing of water. As the unit travels, debris is sucked up through the neck and then the hose, past the suction port, through the pipe, and stops at the filter pump strainer basket, while smaller debris passes through to the filter. Adjustments on the hose, the unit itself, and flow volume will create different cleaning patterns, so as to maximize pool coverage. The more flow is generally better for speed and vacuum ability, however too much suction can cause the cleaner to move too fast or possibly get stuck on uneven areas of the pool floor.
