Nice vacuum for small areas
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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.
