Wow, really a very awesome product! I have two cats that share a toilet as much waste is produced. But on the other hand you do not want running twice a day for dustbin, which is on the other side of the (very large) land. In the bucket you can easily collect the waste of 2-3 days. It's super easy by the included blade and not too much litter is discarded unnecessarily, because the clean litter can fall through. From the opening, briefly pulling and off. Even after 3 days, when the bag is really brimming, you can smell anything! A dream! Absolute buy recommendation! And if you rather than the original cartridges other films buys here, you save good money.
