suction side cleaners are junk or at least my polaris is!!

Polaris telling to to put the jets on the returns down all the time if I was to make sure my cleaner circulate around my pool and clean properly. You want to know the truth? *****Yea right!!!******

For what it's worth --- I had a Dolphin Diagnostic which was nothing but trouble , Sold it on Ebay and bought a top of the line Aquabot (T-4) cost double the Dolphin but is worth every penny. Put it in the pool and forget about it. Come back an hour or two later --- Clean pool .

My advise ----- Buy the best once --- not the cheapest 5 or 6 times.

I have a suction side that works pretty well from this company:

The downside is that when the solar is on, the cleaner does not work as well. It is difficult to set the suction properly for with and without solar. If I had to do it over again, I probably would go with a robotic so I could run it at night without having to run the main pump.

That is the one (well the 4x4 actually) I have been looking at.
I don't have solar nothing, But do you mean a solar blanket, or solar collectors?
Actually my navigator has been a pretty good cleaner, just wore out after 5 years of running around the pool (go figure, plastic against plaster). I actually have not heard anything bad about the Thepoolcleaner, but information is hard to come by. I was hoping for something at least as good as the navigator and a little better at leaves and acorns. Something I can leave in all the time.

By solar I mean solar collectors. The issue with solar is that it adds return head (i.e. PSI goes up) which reduces the flow and also reduces the suction somewhat. I can adjust the amount of suction to the cleaner with a valve but I do not want to do that for each time the solar is on or off so I must make a compromise of somewhere in between. Too much suction on the cleaner is not a real problem but the pump can draw in air when the suction is too great. Again not a real big issue.

The best thing about thepoolcleaner is that it requires less suction than most other cleaners so for a low HP pump or with solar, like me, it will still work when the suction drops a bit. However, when the suction drops, it moves slower and will not climb the walls as well. Still not a bad trade off.
