Fantastic price for such great value
Love love this vacuum l!!!
Love that it’s easy to find replacement parts and for every part you’d need.
It does a fantastic job mapping out the floor and rooms. You can see where it’s been on the map and if you’re mopping, that feature makes it great because you know where you can go ahead and mop. It’s SO MUCH QUIETER than the Rumba and the Shark brand. It gives you the option to select rooms that you want vacuumed without having to do all rooms, it does use a bag and that concern me at first because I didn’t won’t to buy bags.
These bags last for a few months at a time and I’ve got an indoor cat so that means lots of hair.
It does an awesome job going anywhere it needs too and does great at picking up. It’s not large size base and fits nicely in a one foot area.
Over all I would definitely recommend and buy again from this company, the price and value to me is way better than the other Big Brands.

Replacement parts
I wish this package included an extra dust bag or two. I wasn’t paying attention when I ordered it alongside my new Eufy RoboVac.
