We feed our dogs in the laundry room and occasionally shut them in there if we have somebody over thats afraid of them and they come in and go out thru there so we can clean them when they're muddy. So that room collects alot of dog hair and dirt.Of course it makes its way under the washer and dryer. Periodically we pull them out and clean under them. Since its gas, and the flex gas line is only so long, we couldn't pull it all the way out. So we would tip it back and clean under the front. 1/2
