I recently purchased this unit and it appears to be working ok. However, I would like to purchase a couple more lenghts of hose. I have an 18x33 oval and it is struggling to vaccum correctly at the far end of the pool. I have adjusted the float on the hose as well as the regulator and got it in its optimal spot it appears. The problem is when it approaches the far end of the pool it runs out of slack in the hose causing it to pull back on the unit. I have some hose for a manual vaccum but the hose diameter is not the same so it doesn't stay together.
