Roborock S20 and Ecovacs Deebot X12 robot vacuums evaluated

Roborock's S20 robot vacuum impresses with its ability to climb over high doorsteps, extended leg design and precise 3D mapping that avoids obstacles while maintaining a low profile for under‑furniture cleaning. The unit combines efficient vacuuming and mopping, uses less water and cleaning solution, operates quietly, and offers reliable navigation, though frequent charging cycles can extend cleaning time.

Ecovacs' Deebot X12 incorporates AI‑driven sensors, 3D cameras and high‑pressure Focusjet nozzles intended to blast away stains before mopping. The robot scans homes accurately, avoids getting stuck, and features fast charging. While its vacuum performance is solid and noise levels are moderate, reviewers note that the mop function does not consistently remove tougher stains despite the high‑pressure jets.
