pool vacuum/filter pumps

[viena]

Hi from the uk, new to forum, I only have a 12ft bestway frame pool 3ft deep and have 2 questions

1. I need something to vacuum up my pool 1st I brought a Pool, Spa and Hot Tub Vacuum its good at sucking big things but if there is a lot of dirt at the bottom of the pool it takes forever and as it is operated by pulling the handle up and down it gets quite tiring after a while. I did look at the ones with the hoses that works with your pump but I don't think my pump is strong enough its only a 530gal Filter Pump which came with the pool, which takes me to my next question. Also looking at the handheld battery vacuum, which one would you recommend.

2. I would like to get a stronger pump but on the bestway page it say I can only use a 530gal or 800gal Filter Pump for my size pool, but I was looking at 1,500gal Flowclear Filter Pump would I beable to use a much stronger pump...

Thank you
