I don't move it to clean under it as often as I should. I do,however, fish out cat toys that get stuck under it. My old refrigerator was a lemon and it only lasted me 5 years but now I have a new one. I bought a brush to clean under the condensor. It's actually a vent brush but it still works well. When I used it, a lot of cat hair stuck to it. If you have pets then you have to expect that this will happen.
