I have it only for 4 days. I cleaned a whole comforter that was "stuffed" inside and out, in three doses. Also, a knitted hoodie-style jacket. Due to its small size, it filled up, I emptied it, cleaned it, and continued. Of course, you can get a larger size. I chose the small one as a trial, which proved to be economical, functional, and miraculous. I don't know how long it will last, but what I know is that I received it (along with something else) within 3 days in the midst of the Coronavirus!
