Need help with clogging cliff sensor

Rick2 · Guest

I have a roomba discovery SE that I am having an issue with. The cliff sensor next to the spinning finger brush keeps getting clogged with little fuzzies and then ends up backing itself up a wall or anything it can find to raise a wheel of the ground and abort. If I tape over the cliff sensor next to the spinning brush, no problem. If remove the spinning brush completely, it works no problem. However, the spinning brush helps get loose tumbleweed pet hair on my tile floors and I need the cliff sensor to be untaped or it will fall over the stairs! So does anybody know why the one single cliff sensor keeps getting clogged with fuzzies next to the spinning brush?

I liked it so much, I bought another one for my upstairs and it doesn't have the problem (yet) as I just bought it a few days ago. I still need the cliff sensor downstairs because I have a drop down family room and although the drop would not be fatal, it keeps dropping a wheel off and thus aborting.

I seriously have to blow it out or vacuum it out every 10 mins or it will back it's ass up a wall and quit...

Thanks in advance,
Rick
