Why does my Polaris 380’s sweep hose get sucked into the vacuum tube?
The sweep hose should be moving in a gentle sweeping motion. You can adjust its motion by turning the adjustment screw until it slows down to a gentle sweeping motion. Also, verify that your sweep hose scrubber is not blocking the opening at the end of the sweep hose. If it is, move the scrubber so that it will not block this opening.
