Maxspect Gyre falling/slipping off glass now after years of use

[steallife904]

Hello, I have 2 Maxspect Gyre XF150s that i have been running in my tank over 5 years. Now all of a sudden one of them keeps falling off glass, like the magnet is weak now or something???? Only happening to one of them. I have cleaned it, the wet side magnet feet, the glass behind them.... nothing. It stays on for some time them falls off when I'm not around of course. Been on this tank in same spot for 5+ years so why now would it not stay? Not sure what to do either, the don't make this one anymore and they use to have advance magnet kit but not anymore either.

Could be increased vibrations due to being in need of cleaning. I put a thing sheet of rubber-backed foam on my XF330s to give them a bit more grip on the back of the tank. It did the trick (provided I don't nudge them).

i could try something like that. i did pull it and clean it and it still falls off.
