Hayward pool vac vinyl /concrete differences?

[waste]

Bill welcome to the forum!!

As I said in this thread http://www.poolforum.com/pf2/showthread.php?t=6372:

One of the reasons I said what I did in the earlier post is because I've seen dozens of 'crete pool owners who have used a liner vac (with the brushes on them) to vacuum their plaster pool and worn down the brushes within a month or so (then they ask me why this thing keeps needing new brushes and sometimes a new vac head because they 'ate up' the plastic where the brushes go). While I'm at it, use the vac with the wheels for a plaster pool - and if one of the wheels comes off, REPLACE IT IMMEDIATELY or you'll wreck the vac and not be able to vac as efficiently!

As you already have the liner vac, use it as long as the bristles hold out (they tend to fail on one side first), then get a 'crete vac to replace it. Unfortunately, I know of no way to convert a liner vac to a 'crete vac [edit] the brushes themselves can be replaced on the triangular Hayward vacs - however, I have NO idea of the cost effectiveness of doing so vs. a new 'crete vac head[/edit]

I hope this answers your question!
