In a suction based cleaning environment this is the combination of components that works well for me.
1. Cleaner- Zodiac Barracuda G4
2. Polaris LCS leaf cannister skimmer
(3) added in after this video- a pool devil pro just to see if I could catch more dust- I can, but it doesn't really create a "circular flow" like they claim, its worth the 20+ bones it cost IMHO
I found the rolling type cleaners dont work as well (for me) as the really simple suction ones.
By adding the Polaris LCS piece not only do I get my skimmer back, I get a better working skimmer that the built in wall unit.
I know a pressure side cleaner is probably faster but overall I dont see how it could be a lot better than this setup and when you factor in the cost of additional lines pumps, and electricity- this is a lot cheaper. It works so well off one pump with no additional complexity its really hard to beat.
The next thing Im going to try is a "Poolskim" return powered skimmer at the step end.
Later an intelliflo VF pump and that should allow me to tune the system further.
