POOL CLEANER IS SLOW

Pressure Cleaners: These cleaners are powered by water, so when they are sluggish, or moving slowly, the problems is usually flow related. Check the filter screens, located at the wall attachment, and in the hose on some newer models. If a booster pump is being used,rechargeable vacuum cleaner be sure that both filter pump and booster pump are operating, and aren't leaking or making funny noises.
With the booster pump running, kneel down next to the pool and grab the pool cleaner hose, and slowly pull the cleaner towards you, inspecting the hose for leaks as you pull it out of the water (some leakage at swivels is normal). When you reach the cleaner head, hold it just above water and inspect it for water moving thru 3 areas - out the rear thrust jet, out the sweeper tail and spraying up into the debris bag. The thrust jet and sweeper tail should shoot water 15-20 feet. Likewise, if you remove the debris bag, water should spray upwards 15-20 feet in the air. If the water is spraying properly out all 3 exits,inground pool cleaner you likely do not have a water pressure problem, but a problem with the drive belts slipping, or a broken axle, or very worn (rounded) tires - or, something stuck between the wheels and the cleaner body.
