The manufacturer writes: "The space around the docking station should be at least 75 cm high, 40 cm long and 120 cm deep." The station with robot is actually 48 cm high, 38 cm wide and 47.5 cm deep. You need a little space at the top to change the water containers, and at the front you need access for cleaning products and the dust bag as well as some manoeuvring space for the robot. The appliance is essentially collapsible at the side.
