Hey, my Kreepy Krawler stopped moving. Lots of suction, but it just sits there kissing the bottom. It used to pulsate somehow so it would move.
By the way, it has done an excellent job for the past year. I have no ladder and only need to sweep the shallow end wall and steps.
check the foot pad thats on the bottom of it, they will wear down & become flat & the suction will make them stick to floor.
Also check for debris stuck inside hole where flapper is which makes the ticking sound.
If it still does not move check gauge on filter if it's high clean filter/backwash as it will slow down when it's to high even though when kk is unpluged it seems strong.
