Important Notes
NOTE BEFORE USING
While using at the dirty pool,please do not put the filter sponge in first, let the pool robot clean several times until the algae gets almost cleaned.
Then add the filter sponge in to purify water quality till the pool is clean.
Filter sponge only does the function of purifying water quality, too dirty or too many algae will get it stucked so that the pool vacuum robot will not move cause lack of water to go on.
Better to clean up the filter sponge each time after heavy usage.
