I am having trouble getting it to suck properly. It looks like it is sucking air, with insufficient water going through the hose.
Its a hassle to get the air out of the hose in the first place. It floats too well. But even when I do, the volume of air in the pump strainer (don't know what to call it - its attached to the pump and has a clear plastic top) keeps getting larger.
When first set up the bug moves all around the pool and you can see it pick up the dirt from the bottom. But gradually it loses suction.
I have backwashed the hose to fill it with water, all connections are tight, I have jumped in the pool and held the hose down to fill it, etc, etc. It moves around fine but slowly stops sucking.
The other day I took it out and put the regular bottom vacuum on and the dirt on the bottom was sucked up in 20 minutes.
Could it be that my pump (1.5 HP) is too large for the volume of the hose? What am I doing wrong?
