Washing windows by hand is something I absolutely despised. Even though I only live on the third floor, leaning out the window with a rag every time was an ordeal. Let’s be honest: window cleaning is that one chore everyone puts off until the last minute. Every time it’s a whole quest: buckets, rags, glass cleaners, streaks that only become visible when the sun comes out. And then there’s the balcony. And the mirrors on the wardrobe. At some point, I just got tired and decided to delegate this to a robot.

This little machine will take away such a headache
So when I stumbled upon the CHOVERY window cleaning robot on AliExpress, I didn’t hesitate for long. It’s a compact device that suctions onto the glass and independently covers the entire surface. You simply install it, press the button — and go about your business. Sounds like science fiction, but it really works. I got it, tried it — and now I can’t understand how I lived without this thing. Let me tell you how it works and whether it’s worth the money.
CHOVERY Window Cleaning Robot: Cloths, Remote, and Safety Rope
The package contents of the CHOVERY were impressive. The box contains the robot itself, a remote control, a power supply, a safety rope, 10 replacement cloths and 4 plastic mounting discs for them, instructions, and two AAA batteries for the remote. So right out of the box you already have everything you need — no additional purchases required. Ten cloths included — that’s generous. They can be washed in a washing machine and reused, so the supplies will last a long time.

Everything needed for normal operation is included
I want to specifically mention the safety rope. It attaches to the robot on one side and to a secure anchor on the other. I attach it to the radiator. Even if something were to go wrong, the robot isn’t going anywhere. By the way, during my entire time using it, there hasn’t been a single fall — it suctions on rock-solid.
How the Window Cleaning Robot Works
The operating principle is simple. The robot runs on mains power — there’s no battery that needs to be charged before each cleaning session. You plug in the power cable, place the robot on the glass, and it instantly suctions on. The vacuum motor power is sufficient to hold the device even on a vertical surface.

Attach the cloths to the robot, and it suctions onto the window
But there’s an important detail: inside the robot there’s a small backup battery in case of power outage. If the electricity goes out, the robot won’t fall — it will continue holding onto the glass for about 30 more minutes. That’s more than enough to calmly remove it.

Remote control is implemented as simply and intuitively as possible
You can control the robot with a remote control. The remote is especially convenient when the robot is working on the outside of the window — you don’t need to open the window to change anything. You can direct it to a specific area or start another pass while staying inside the room.
How to Properly Clean Windows with a Robot Without Streaks
After several months of use, I’ve developed my own method that delivers perfect results. Let me share it with you.

First dust off the windows with dry cloths, then wash with wet ones
- First, I install dry cloths on the robot and run the first pass. The goal of this stage is to dust off the glass, removing the main dirt and dust. If you immediately use wet cloths on a dirty window, you’ll get streaks. A dry pass solves this problem.
- After that, I switch to wet cloths and run the robot again. It goes over the same window once more, but now with wet microfiber. The result is perfectly clean glass without a single streak. The mirror on the wardrobe after this treatment looks like it was just installed.
When the cleaning is done, the robot emits a beep signal — no need to stand nearby and watch. Heard the beep — it’s done, take it off.
Cons of the Window Cleaning Robot and Where It’s Actually Useful
It would be dishonest not to mention the drawback. There’s one, and it’s obvious — corners. The robot has a rounded shape and physically cannot reach into the corners of the window frame. A small uncleaned area of a couple of centimeters remains, which you can wipe by hand in a second if needed. But let’s be realistic: this is a minor issue compared to the fact that the robot will wash the entire remaining surface of the window by itself. For me, this is an absolutely acceptable compromise.

Due to its shape, the robot can’t handle corners
However, its range of applications is wider than you might think. Windows are the obvious use, but far from the only one. I regularly use the robot for cleaning mirrors: on the wardrobe, in the bathroom, large wall mirrors. The result is just as excellent. The robot handles any smooth surface — whether it’s glass, a mirror, or ceramic tile.
By the way, one buyer in the reviews wrote that they tested the robot on bathroom tiles — and it cleaned the wall in automatic mode without any issues. So if you have large mirrored or glass surfaces in your home, the robot will come in handy for more than just windows.
