Check the hose for leaks by lifting each section above water while pump is running. Consult a pool shop in your area. Problem: Cleaner travels in a repetitive pattern. Solution: Adjust return jets downwards. Verify proper hose length. Ensure cleaner sits flush with the pool floor. Adjust the position of hose weight if necessary. This should be done at the deepest part of the pool. Remove or add one hose section. Inspect the Regulator Valve and flush away any debris build-up.
