Iíve had the Poolvergnuegen 4x Pressure unit in my 35k gunite pool for a couple years.
It does well except for not getting the fine debris/dust/dirt which flows through the bag and back into the pool, or is just not picked up. I miss my old kreepy-crawly style vacuum for only that reason, it was good at the fines.
Iím considering the 4x Suction with a large in-line leaf catcher to keep big stuff out of the filter. The pool has overhanging evergreen oak tree, so small leaves/twigs all year, and hundreds of ĹĒ acorns for a few weeks each Fall.
The 4x Pressure does OK with the acorns, occasionally jamming, the bag fills up 2-3 times a day during these weeks.
Does the combination of 4x Suction with a big inline canister sound like a good idea? I now have a 2spd pump as well, run on high for a couple hours, Low for 10hrs. The 4X Pressure still does OK even on Low. I'd like to hear from anyone with experience on the 4X Suction with 2spd pump as well.
