The Roborock E4 has a good selection of automation features. It can be used without initializing its companion app, as its physical buttons can be used to command it to start cleaning an entire area, spot clean, and return to its charging dock. With the companion app, you get access to many more options. It lets you schedule cleaning times, update the firmware, check maintenance status and cleaning history, and even remote control the vacuum to reorient it. Its OpticEye navigation system relies on internal gyroscopes and motion tracking to build a temporary map of the room it’s cleaning, but doesn’t allow you to schedule individual room cleanings. You also can’t set up virtual room boundaries in their companion app, unlike the Roborock S5.
