Zodiac mx6 doing wheelies

[kul]

I have the zodiac mx6 in link below. When it’s vacuuming it has started to just lift onto back wheels so not vacuuming properly. I checked that it’s clean, I tried higher/lower suction, tried using my skimmer pole to push it down. Nothing. It has worked fine until now. Any tips?

Solved the issue. Turns out an adapter (link below) I installed for the first time to connect to an old leaf catcher I had was causing a suction issue. Strange because it’s sold by the same company as the vacuum. Anyhow, that’s that. I don’t know how to delete a thread so just posted this update.
