Well our carpet cleaner didn't pull the vacuum out of the carpet like it should and I noticed the clasp on the back of the tank was broken, me don't know how long ago it was broken, maybe she broke it and didn't tell me, or one of the kids did, but when I looked at it, if it wasn't locked, it didn't have a very good seal , so I said let's buy another tank; so we bought this tank, put it in and locked it like it should and now the carpet cleaner is working properly again. Thank you for makingโฆ
