I have a SwimLine "Vinyl Liner Vacuum Head" that looks like this:
I hate it. I am ready to throw it in the trash.
I can't push down on it (from the outside of the pool with a telescoping pole) hard enough to get good bristle contact when moving forward. When moving backwards it flips itself up and tries to rise (no, I'm not going fast). I have tried with a vac hose that floats and one that doesn't. I have added 5 lbs of lead shot to the top of it (in a plastic bag of course ). No matter what I do, I can't get it to "stick" to the bottom and vacuum well while also getting continuous bristle contact. I don't think its a low suction issue either. I'm pulling about 60 gallons/minute through the vac head.
I've looked at the IG style with rollers, but I'm not sure they are good to use in a vinyl AG. I'd really like a weighted vac head (even if its 20 lbs) with wheels, and bristles. I don't want to just suck stuff off the bottom, I want to brush the bottom while I'm vacuuming. I want it to be solidly planted on the bottom and be able to stay there even with the hose pulling on it. I would also prefer that the bristles be long enough to get into the small crevices and variations that exist on the bottom of a AG pool with a sand base. Any suggestions?
What about these: (images are clickable)
Do these style heads have brushes under them?
(Just kidding on the last one - I'm not spending $1,032.48 on a manual vac head! )
