Ecovacs Winbot X: A cordless window cleaning robot with a unique safety system

Published October 30, 2019 Updated: February 10, 2026 no comments 9,391 views

Washing a window can sometimes be a difficult and even dangerous task, requiring considerable effort and time. Thanks to advances, this can be accomplished effortlessly with a robot. Ecovacs Winbot X is the first cordless window cleaning robot. It's worth noting that it was awarded a CES Innovation Award Honoree and features an intelligent routing system that allows it to reach difficult areas and ensure a thorough cleaning. The device can clean not only windows, but also mirrored surfaces, frameless glass, smooth floors, and even ceramic tiles. Thanks to the robot, there's no need to climb into hard-to-reach or high places to clean the surface. This article provides an overview of the Ecovacs Winbot X, exploring its features and functionality.

Equipment

The Ecovacs Winbot X comes with:

Robot cleaner.
Safety rope (length 2.5 m).
Remote control (+ required number of batteries).
Power adapter.
Extension.
Safety mount for glass.
Microfiber cloths – 4 pcs.
Cleaning liquid.
Instructions.

Winbot components

Appearance

The Winbot X robot is made of white plastic, with a square body measuring 25 x 25 cm and 10 cm high. A large handle is located on the front side, allowing for easy placement of the robot on the surface being cleaned. It also houses a large button for activating the robot.

Top view

On the bottom side are:

two tracks for moving along the surface of windows;
a microfiber cleaning cloth is placed around the perimeter;
two rubber scrapers;
battery compartment cover secured with two screws;
drop and pressure sensors;
suction hole of the turbine, due to which the robot is attracted to the window.

Bottom view

The Winbot X is quite heavy, weighing 1.8 kg, making it unlikely to stay securely attached to a window without falling over. However, Ecovacs' developers have done a great job—a powerful suction system keeps it firmly planted on windows. A hole in the center of the base draws in air, creating a vacuum between the window cleaning robot and the surface being cleaned.

A key component of this window cleaning robot is its two-and-a-half-meter safety cable with a suction cup. It is securely attached to the body, preventing the operator from falling.

Technical specifications

Below are the technical specifications of the Ecovacs Winbot X:

Overall dimensions	24.5×24.5×10.9 cm
Weight	1.8 kg
Noise level	62 dB

Functional capabilities

The Ecovacs Winbot X is equipped with a built-in 3000 mAh battery, allowing it to operate autonomously. Please note that many models require a power connection to the window cleaning robot. The built-in battery is only used for emergency situations, to prevent the robot from falling off the window in the event of a power outage.

In fact, it's not entirely clear which is better. While the robots are supposedly autonomous, their operation time is short, and their movement is still limited by a 2.5-meter safety cable. Considering the robots' runtime is 50 minutes, and they move at an average speed of 2.4-3 minutes per square meter, this would be enough to clean no more than 17 square meters. The safety cable won't allow them to clean this entire area on a single charge.

The suction cup attachment unit, with its 2.5-meter safety cable, communicates with the robot via a 2.4 GHz frequency. If the air pressure on the main unit's suction cup drops below 3.5 kPa, a safety feature is activated and the attachment unit retracts the cable. This is called an active safety system.

Insurance

Depending on the surface size, the cleaning robot automatically determines the optimal cleaning path (either an N- or Z-pattern). A pressure sensor is located on the bottom, and edge sensors are located in the corners.

Sensors

As noted above, the device can successfully clean not only windows but also other surfaces, such as mirrors, glossy furniture, glass doors, and shower panels. However, do not use it on cracked surfaces, as this may weaken the robot's grip and cause it to fall.

Surface mounting

Control is possible using buttons on the body and the included remote control. Unfortunately, the Ecovacs Winbot X cannot be controlled via a mobile app.

Advantages and disadvantages

In terms of advantages, they're standard for all robotic window cleaners: they make it easier to clean windows on floors and large surfaces. Plus, Ecovacs produces fairly reliable products with good reviews. The only important detail is a new way to secure the robot using a suction cup. This is certainly interesting, and other manufacturers will likely adopt this idea in the future. Although relying on a suction cup is a bit scary, it'll take some getting used to and testing out the safety in real-world conditions.

But opinions are divided on this model. Yes, the robot cleans well and moves quickly across glass (on par with its competitors), but the idea of autonomous operation isn't entirely practical. Window cleaning robotsPlugged-in cleaners perform similarly, but don't require constant charging. This robot, however, requires multiple charges to be able to clean all the windows in your house or apartment autonomously. Considering that charging takes over two hours, this isn't entirely convenient.

If the model were mains-powered but had longer battery life, then yes, it would be considered a plus, but since the Ecovacs Winbot X positions itself as a cordless window cleaning robot, the advantages aren't entirely clear at this stage.

Considering the model's price is slightly over $300, and it lacks smartphone control and interesting features like a moving cleaning unit or automatic surface wetting, we believe this robot isn't the best on the market.
