There were many cleaners like this (Cheaper, small plastic handhelds under many different names, I own a similar brown model under "ANNEX" for example). These cleaners often times used a small cotton filter on the inside chamber, although bags could be a possibility in this model's case. this are very good cleaners, I found mine handy for quick clean-ups of the HouseRabbit (Pine shavings, Food pellets, etc). A nice little cleaner that is handy around the house!
