Satisfied? Oh not Pay!

Hello,
Rate this product or give a positive comment takes the joke! How to say ... This product is totally ineffective and even record is contradictory.
And yes aspiration is done on the pipe from the bottom of the pool (plugged up the filtration device) and "expiration" is through the top tube (connected down the filtration device) and not the reverse. But that's not the problem ...
I had foolishly said that I preferred to buy it cheaper hardware than a real vacuum (to totally prohibitive and outrageous prices) but inevitably it does not work ...
In fact aspiration is almost zero! So to suck "dirt" at the bottom of the pool ... No comment.
Finally saw now the opacity of the water in the pool, I'll empty, clean, and overwinter my pool ... By cons for the money back, can I request a refund? ... Please your attention ...
