I purchased this product from a hardware store. The "removable suction lens" is NOT REMOVABLE!!!!!. It is black plastic--not clear. It does NOT have a latch. It is screwed into the tank in 5 places. So I would have to unscrew all screws in order to remove it and clean it. I don't know what to do about it. I cannot return it to the store and since I didn't order it from Bissell directly, I cannot return it to them. This is the FOURTH Bissell product I own.
