Pros: It works great when washing with water. The MiHome app, which should have been utilized for the original, best-selling Xiaomi dry vacuum cleaners, is less user-friendly and less effective than Roborock. Contrast several: Sometimes it's extremely dimwitted in terms of determining a path; it'll start driving around the room without any prior instruction or calibration, and then turn off with an error before it's even finished. I've need to take it home and restart it multiple times. Thankfully, this only occurs in 5% of instances, but it's still annoying if you set it on to work remotely and then have to restart it when you get home. Consumables are pricey in comparison to my old Xiaomi vacuum cleaner, but I can not perceive any significant technological complexity in the filter or the broom.
