It's multi-functional and stylish, and I'm happy with it! However, Both my cat and dog are scared of the sound and run away, so I couldn't use it (；ω；) The sound is like a vacuum cleaner. Not too loud, but not quiet either, haha. I used it about 2 or 3 times and then put it away. The attachment in the third image picked up hair really well! The room cleaning attachment in the sixth image is also usable ◎ There is no box.
