Hi all. I have 3 of the Scoop Free boxes for 4 cats. 2 of my boxes are starting to squeal when cycling. It seems as the rakes get closer to the purple cover it gets noisier. I've had my boxes apart on several occasions (knocking the plug receiver out of place, changing rakes, cleaning, etc) and I have not figured out what I need to lubricate to eliminate the squealing. I've watched them work, they don't seem to be moving slow. Just as I'm writing this I'm thinking the one thing I have not done is take the purple cover off and cycle them to see if the squeal goes away.
In the meantime, I think I still would like guidance from my fellow scoop free folks who use the forever trays. Thank you all in advance. Betty
