【Double Chamber Design】Compared to the common single chamber filter bags on the market, our double chamber filter bag has two compartments that collect and filter debris from the pool water together.

The capacity of collecting debris is twice that of a single chamber, which will save you time and effort in pool maintenance.

You'll also enjoy clear water, free of debris and fallen leaves.

【Compatible Models】Our dual chamber pool cleaner bags are compatible with polaris pool cleaning robot 3900 sport, P39, 280, 280 tank Trax, 280 black max, TR28P, and 480 PRO models.

Tip: Please pull the zipper several times before use to make sure it is smooth when pulling.

【Collecting Pool Debris】Our pool sweeper filter bag captures leaves, small pebbles, sand, silt and other dirt from the pool water.

It ensures that your pool stays sparkling clean throughout the season.
