A vacuum head that has a brush on the bottom - no wheels.
To remove sediment from a vinyl quick set pool you will need a pool vacuum. Move the vacuum very slowly as you work so that it has a chance to catch everything.
A fiberglass pool is far superior to a vinyl liner pool. It is also about twice as expensive.
A concrete pool is better any where if it is done professionally.
A concrete pool is better just about any where unless there is a lot of ground movement.
In the frost belt Vinyl is better..Gunite is one of the strongest pools but when it freezes it can crack.. I agree. Vinyl is better and it will feel so soft and smooth on your feet.
Inground vinyl is better, their is less exposed part to the oxigene, therefore, last longer.
Not all pools have pool liners, some are simply painted concrete. Depends upon your type of pool. If you are concerned with longivity, then consider a thicker vinyl.
how to program a pool vacuum
Gunite is a type of cement mix used in the walls of the pool, whereas a vinyl lining is just a layer on the walls, generally used for waterproofing purposes. So, either of them will do, but my personal opinion is that using a lining is always better (hence vinyl lined pools are very common in England and other countries)
Concrete retains heat better and it a more permanent solution. Vinyl is often like a bladder to hold the water within a tin frame. The layers are so thin that heat retention is negligible and therefore not an optimal solution for a heated pool.
If you have water behind your vinyl in ground pool liner, you should first lower the water in the pool to normal levels if it is over-filled. Make sure that the vacuum pipe is clear, unclog it if it is not. Once it is unblocked let the water from behind the liner flow out.
All day long. Concrete pools have real tile instead of the fake liner tile look. You can update a concrete pool later on as styles change: with vinyl it's final.
