Bought this around a month ago and have been using since. Really convenient and easy to use. Now no need to empty the vacuum canister in the trash can, instead just empty in this and it collects in the dust bag inside. Depending on how often you vacuum and how much dust collects, i would say that the dust bag can hold around 4 weeks of trash. The only complain is that the replaceable dust bags for these are nearly impossible to find (unless you want to pay more than retail). Samsung please fix this and make the bags easily accessible or just have this swapped/replaced with something that is still useable. Other than that a good and convenient product.
