    It works great on my hardwood floors. It’s quiet and doesn’t freak my cats out. It has a light on front which is helpful in corners. No more holding my breath while emptying the dust. It’s automatic! Worth the money.

    Really nice little vacuum. I got this mostly for my hardwood floors. It works nice with adjusting levels of power, and the self emptying feature is amazing. I haven’t emptied it out yet, but since there’s no bag, I wonder how much will stick to the sides of the container. Especially dust and hair. That might be a drawback.
