Hayward pool vac vinyl /concrete differences?

[BillF99]

I've got an inground plaster pool and just bought a used old hayward pool vac that is for vinyl pools. What is the difference between the vinyl and concrete models? If it is important can they be converted?

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!

Thanks for the reply. Unfortunately it doesn't seem to apply to the model I have. It is a early "pool vac" - I would guess a predecesor to the "ultra pool vac" It is a suction cleaner that has no bristles and seemingly no wheels. It looks like it kind of rocks or occilates forward on plastic pads on the bottom. I've searched all over to try and find out what the difference is between the concrete and vinyl models, but to no avail.

Thanks for the welcome. I come here every couple of years when I have a question I can't seem to find the answer to. I'm always amazed that the forum still exists despite the usual absence of a moderator. That's not a critique . . . I'm just impressed that it survives. Everything I do seems to break the second I don't pay any attention to it. Lots of good info here, I'm glad it exists.

Bill, sorry for the inapropriate response I thought the question was w/ reguards to manual vac heads (oops). I don't think there's a huge difference between the 2, but if there is one, it's going to be that the liner model isn't protected against the abrasion that the plaster will cause to the edges of the unit, I'd just keep an eye on the surfaces of the cleaner and look for wear and try to pad/ protect the areas that seem to be degrading too quickly.
Sorry to have misunderstood the ?

The biggest (maybe only) difference is the foot pads. The vinyl model has cork pads that will grip the smooth liner. The concrete model has different pads that will not break down against the rougher plaster. I would recommend ordering yourself a set of new pod shoes (AVX414P). They should not be very expensive and I can gaurantee you that the vinyl shoes will not hold up for very long at all.
