The moment you want to remove the dust, you can start using this vacuum cleaner. Bringing out the cleaner from the storage, plugging it in, and putting together the hose are enough to discourage you to clean the room. Therefore, the Metaphys cleaner "uzu" is ready to be used at any time. You don't need to put it in a storage, and you can place it anywhere in your room. A hose is an inevitable part of the cleaner, but it is bulky and often destroys the design. Considering these points, "uzu" is cordless, and has a collapsable handle and an extentionable hose.
