Roborock Q10V vs Dreame D20: Q10V navigates smarter, D20 is the smarter buy for most people

Regarding the Roborock: The Q10V uses cameras and sensors to see obstacles coming and sidesteps them smoothly, while the D20 bumps into things and reacts afterward. The Q10V is the better machine with fewer “why did you just bump into that chair” moments. But the D20 cleans nearly as well, costs way less, and won’t leave you feeling like you overspent if your house doesn’t actually need a robot vacuum.
