I used to have that problem till I learned how to correct the problem
first scrap off the glass with a razor blade removing any build up on the glass , then remove the power head and clean off the the suction cup with paper towel and rubbing alcohol as it evaporates in seconds , next put a very light coat of veg shortening over the suction cup just to make the suction cup look shinny , now it will stick to your glass like it did when it's new,
I used to throw out so many power heads because I didn't know about this simple trick ,
Thanks to one of our vendors with there tips and tricks page I learned this little secret ,
