The threshold can be overcome up to the lower edge of the front bumper, when it hits the threshold, the sensor in the front bumper is triggered and the robot turns around. However, since carpets have flexible hair that gives way, a robot hoover can often make it up to 2 cm high carpets. However, a door threshold does not give way and 2 cm is often the threshold for most robot hoovers to climb over. Under certain circumstances, ramps are still needed.

In our house he doesn't have to climb a threshold, but I could imagine that this could be a bit difficult. Perhaps a bevelled piece of squared timber could help? He would be worth it😉
