The Roborock Q10V sees obstacles coming — the Dreame D20 bumps into them first

The Dreame D20 bumps into things and moves around them reactively. The Q10V uses cameras and sensors to see obstacles coming and sidesteps them smoothly — plus it learns over time. The honest take: the Q10V is the better machine with smarter navigation and fewer “why did you just bump into that chair” moments. But the D20 is the better purchase for someone new. It cleans nearly as well, costs way less, and won’t leave you feeling like you overspent if you realize six months in that your house doesn’t actually need a robot vacuum.
