Essentielb WCR1 Cleanbot (window-cleaning robot): our review

The kitchen window above the sink has collected splashes, and the sliding door carries fingerprints at exactly the height of the smallest household members. Ready to stop giving every pane a personal polishing appointment? The Essentielb WCR1 Cleanbot combines automatic spraying with a deep cleaning mode, a useful starting point for handing over some of the repetitive work.

Its 60 ml reservoir is a typical tank size for window cleaning robots. Think of it as a refillable supply for the glass in front of you, with trips to the sink depending on the surface and how much moisture the job needs. Deep cleaning is the stated mode, but the name does not promise that dried splashes will disappear without additional attention.

We like the straightforward combination. You do not have to supply every spray yourself, although the cleaning solution and condition of the cloth still influence the finish. Sunshine remains a very demanding houseguest.

Framed windows and tiles are the supported surfaces. That gives this robotic window cleaner a defined place in a home with conventional window frames. For the living room picture window, the surrounding frame matters just as much as the broad expanse of glass that has been staring back at you all winter.

Tiles also belong within its verified scope. That does not make every bathroom surface a suitable destination: mirrors and frameless shower panels fall outside the confirmed compatibility. If shower glass is the chore driving your purchase, confirm explicit support for that surface before choosing.

A dining room with several separate windows brings another practical consideration. You still place the robot, move it between panes, and retrieve it. A broad framed window gives you a different setup from a row of smaller windows interrupted by curtains and furniture. Clear a route before starting, particularly if moving between panes means reaching around the dining table.

The WCR1 Cleanbot uses mains power during cleaning. Arrange access to an outlet before placing it on the window, and think about where the power connection will sit while you move between panes. Its UPS backup battery serves a different purpose: it is intended to keep the robot attached during a power interruption, giving you time to retrieve it.

The advertised holding time is 20 min, a typical backup duration in this category. Our assessment places it well on this criterion. Treat that interval as time to respond, rather than time to finish whatever else you were doing. An upstairs window makes access especially important.

Can you reach the robot promptly from its working position? Settle that before starting. Follow manufacturers’ instructions to secure a safety tether to a fixed anchor and remain nearby during cleaning. Backup power supports retrieval; it does not keep the cleaning session going.

A remote control lets you issue commands without reaching across the glass to the machine. For a wide dining room window with furniture nearby, that is useful: reaching the controls and reaching the robot are separate jobs. You still need room to place and recover it.

The advertised noise level of 65 dB sits around the category average. Expect an appliance working nearby, so a conference call beside the window may be an awkward pairing. Coffee on the patio could suit the occasion better, provided you remain nearby and supervise.

The 1,45 kg weight matters most during transfers: make the next window accessible before lifting the robot, so you are not holding it while shifting a chair or drawing a curtain. Its 7 cm body height tells you how far it projects from the glass. Check the space beside blinds and other obstructions before placement. Neither measurement tells you how easily a particular window will accommodate the whole setup, but both help you picture the job beyond the cleaning itself.

For a sunroom with broad glass panels, Lubluelu CHYW201 for expansive glass has a higher water tank capacity than WCR1 Cleanbot, at 160 ml. Choose Lubluelu CHYW201 when a larger tank is the feature you want for large picture windows. More water aboard gives you a larger supply before refilling, although the amount of glass covered still depends on the cleaning job.

Ecovacs WINBOT MINI for backup duration has a higher backup battery holding time than WCR1 Cleanbot, at 30 min. Ecovacs WINBOT MINI has a similar water tank capacity to WCR1 Cleanbot. The reason to choose Ecovacs WINBOT MINI here is the longer interval available to retrieve the robot after interrupted power.

Our choice is direct. For the sunroom where refilling interrupts your progress, choose Lubluelu CHYW201. For a household that wants a typical tank size with more time to respond to an outage, choose Ecovacs WINBOT MINI. Let the window chore you actually dread make the decision.
