First, I would to say I tried alot of robot vacuum including, Roborock, Ecovacs, Xiaomi, iRobot. And from my experience by far the M7 PRO Is the best for few reasons. 1.The navigation is one of the smartest 2.Dual side brush is a must(thanks for the update of the speed of the side brush) 3.The option to add auto empty dust bin is awesome(I got 2 big dogs and the auto empty bin sucks everythings in the dust container of the robot. 4. From my experience the App works real good: add no-go zone/ Timer and program the robot. Saved map. 5. The robot is very very good at cleaning and very fast too and one of the Strongest too. I would like to win a M8 Pro for my second Floor!!! I highly recommand buying M7 Pro! #ProscenicRobot #Proscenic
