    I really like this lightweight vacuum. Easy to set up. The only downside is with cat litter clean up. Bits left behind the vacuum on hard surface so you have to turn it around for another swipe.

    I’m in love. Switched from Dyson and have no regrets. It’s so light and moves effortlessly. Love that it cleans itself.

    Works just as intended! I love the self cleaning mode! It makes it easier to ensure no gunk gets stuck and makes it hard to clean! Stays charged extremely long.

    VERY pleased with this purchase. Had considered Rumba type but this vacuum is just perfect. It is super light weight and having the advantage of using only the top portion alone is fantastic. Great for dog hair. Great for dusting windows. Good on kitchen floor

    This thing is amazing. we used it a week with two large dogs and still have not needed to empty the trash tank. I is great for stairs and hard wood floors but we also us this in the kitchen. Well worth the money with a boost mode when you need that extra kick to get something that is being a little bit stubborn.

    I wish the suction was a little bit better but it does the job for the hardwood floors like our kitchen and dining room. It is also handy that there is no cords which is my favorite.

    The vacuum arrived quickly. It was simple to put together. My son loves this vacuum. He loves that it’s cordless and easy to maneuver. The only problem we had is that the first docking station stopped working. We called the manufacturer and they sent a new docking station. So far it’s doing its job cleaning out the dirt from the vacuum. We have lots of dog hair and this vacuum does a great job picking that up.

    I just love this vacuum. Cleans great, has auro setting and changes speed between carpet and wood floor. Super easy to use. Very accessible so little spils are immediately vacuumed up.
