My Polaris 3900 sweep hose simply drags behind the vacuum. I've adjusted the sweep jet, but it doesn't appear to do anything. I'm also finding that the vacuum is gettin hung up when it gets to a the stairs

The hose connected on the interior of the polaris could be disconnected. seperate the housing and you will see the hose. Or you need more pressure at the wall. Try closing are reducing the amount of flow to the skimmers to up the flow at the wall connection. Your back up valve should pull the polaris off the steps. Set the rotating jet propulsion on rear to 11: 00 position.

Hey Thad, maybe YOU need to open up the 3900 and see that there is NO internal hose - It's all part of the rear housing!
Check that rpm are in 32-36 range, if so did you adjust by pushing the tail into the rear of unit and turning it clockwise?
I experienced the same problem with the sweep hose on my new Polaris 3900. Tried adjusting the tail pressure via the screw adjustment at the rear of the unit - no difference. Checked all hoses/connections for leaks - no difference. Removed the blue diffuser at the wall - no difference. Finally decided to remove and clean the clip on scrubber/diffuser at the end of the tail. It didn't look all that dirty, but I went ahead and cleaned it anyway. FIXED THE PROBLEM!
