Kärcher RCW 4 — Usage guide
Use the device only for household cleaning permitted by the manufacturer and on suitable glass. The minimum window size is 40 × 40 cm. Pre-clean heavily soiled windows; never place the robot on wet glass. For exterior glass at height, attach the supplied 4 m safety rope to a suitable stable point as directed by the manual before installing the robot. Keep the rope clear of its travel path. Never lean or climb out of a window. Before starting, keep the area below clear of people and pets, and keep the device within sight and hearing while it operates. Stop outdoor use in strong wind or precipitation, or if a fault or warning occurs. Do not use the robot on damaged glass, frames or anchor points, or where safe installation and tethering cannot be ensured. Use a professional cleaning service in that case. Use only original Kärcher window detergent. Mix a 20 ml RM 503 portion with 230 ml water (250 ml total); always follow the issued package and manufacturer instructions. Return the robot, three microfibre cloths, remote, filling bottle, safety rope at the agreed time. Detergent is not included in the rental set.
