Scheppach WCR72 (window-cleaning robot Mains-powered with automatic spraying): our review

The living room picture window can collect a winter's worth of grime while you are busy enjoying the view through it. When cleaning finally makes the weekend calendar, the Scheppach WCR72 offers suction rated at 2800 Pa, among the lowest advertised suction levels for window cleaning robots. That is a modest starting point. It gives us reason to keep expectations grounded, especially if the glass has been neglected rather than regularly wiped.

Does your sliding glass door mostly need help with fingerprints and everyday marks? Automatic spraying is a useful feature for that routine, applying liquid without making you handle every application yourself. The remote control also gives you a separate controller to keep nearby while supervising the work. Your windows have apparently acquired their own remote. The couch may be jealous.

Results still depend on the dirt, cleaning solution, and condition of the cloth. Suction pressure cannot tell you how stubborn residue will respond, and the corners may need your attention afterward. We would approach this robot as help with recurring glass chores, with a cloth still available for finishing touches.

An upstairs exterior window changes the conversation. Starting the cleaner is only part of the job; you also need a practical way to reach it again. This model runs from an outlet during cleaning, with electrical power specified at 72 W. In everyday terms, plan around the power connection and cord route before putting it on the glass. The electrical figure does not tell you how quickly the window will be finished.

The UPS backup battery is intended to keep the robot attached during a power outage for 20 min, a typical backup duration in this category. Use that reserve to retrieve the cleaner. Cleaning requires mains power, so treat an outage as your cue to bring the robot back within reach.

As manufacturers' manuals instruct, secure a safety tether to a fixed anchor point and stay nearby during cleaning, especially upstairs. Before ordering, ask the retailer about the included tether and extension cord, replacement cloths, warranty, support, and return policy. Those practical answers matter when you are arranging a household chore around an electrical outlet and an exterior window.

The robot's weight is 0,98 kg: that is the load you will lift onto the glass, retrieve, and carry to the next framed window. Its height is 6,8 cm, a useful dimension when thinking through placement near surrounding trim. Neither measurement removes the need to reach the pane comfortably. If the upper window already calls for a stepladder, handing over the wiping will still leave you responsible for getting the cleaner into position.

We like the straightforward remote control. For someone who prefers a dedicated controller during household chores, that is an appealing detail. Set it somewhere accessible before starting, particularly if you will be moving between the living room and the backyard door. The overall assessment in our scores is well placed, which makes this a credible candidate for a manageable routine.

Verified compatibility includes framed windows and mirrors, and outdoor cleaning is supported. A mirror that collects everyday smudges therefore fits its stated surface range. Manufacturers' manuals advise against cleaning exterior windows in the rain, so choose a dry spell for outside work. How comfortably can you reach each surface before the robot starts? That answer should shape your cleaning route.

The reservoir holds 35 ml, a small tank that needs frequent refilling. For a sunroom with broad glass panels, that means repeated interruptions to replenish the liquid. This is what holds us back. Automatic spraying is welcome, but you remain involved in keeping its supply topped up. The robot can take over a repetitive task without making the entire afternoon yours again.

For that specific limitation, the Lubluelu CHYW201 has a higher water tank capacity at 160 ml. The Lubluelu CHYW201 is the alternative to consider when the gap between refills matters more than keeping this particular model on your shortlist. A larger reservoir is a practical reason to change direction, rather than a promise about the final appearance of the glass.

For buyers who put backup duration first, the Ecovacs WINBOT MINI has a higher backup battery holding time at 30 min. The Ecovacs WINBOT MINI therefore makes more sense when additional retrieval time during a power interruption is your priority. Choose around the interruption that bothers you most: stopping to refill or having less time to recover a stopped cleaner.
