I couldn't be more impressed with this robot vacuum. After testing every high end model in the Roomba lineup, a Neato, and a couple of the highest ranking Chinese robot vacuums available on Amazon Prime, I settled on the Xiaomi Mi purchased via Walmart.com a couple of months ago. The mapping and detail of this unit is unmatched and it climbs over the thickest of rugs/carpets with ease. I recommend this vacuum to anyone willing to spend the money, especially if you're considering a high end Neato or Roomba.
