People living in urban environments where construction projects spew a lot of dust into the air will adore the HOBOT-2S. This bot will scrub away all the window crud preventing sunlight from streaming into your home, which makes living conditions pleasanter with zero effort required from you.

If you’re tired of paying for an expensive window cleaning service, consider getting the HOBOT-2S. You’ll be able to save money while kicking back and relaxing on a Sunday morning enjoying a leisurely brunch while your dirt-sucking droid goes to town.



High-Frequency Ultrasound Technology

With a simple button press, the Hobart HOBOT-2S cleans your windows efficiently from top to bottom. It does this by using high-frequency ultrasound technology to nebulize water into tiny 15μm particles that create an anti-static film on glass surfaces, which helps to repel dust and dirt powerfully.

Dual water tanks with left and right-side ultrasonic spray nozzles ensure complete coverage and a better clean. Then, the HOBOT-2S wipes away dirt with microfiber cloths that minimize streaks and don’t leave lint.

Multi-Surface Cleaning

If you’re looking for a droid that can clean more than windows, this machine is right up your alley. That’s because it can also clean bathroom mirrors, large mirrored cupboards, and tile walls.

Able To Clean High Windows

If you wanted to clean high windows in the old days, you needed to put in hours of back-breaking work using a cumbersome squeegee on a long pole. With the arrival of the HOBOT-2S on the technological stage, those days are over. It makes this kind of job so much safer because you won’t need to climb ladders to get your glass surfaces sparkling clean.

Built-In Protection From Premature Demise

Lesser winbots have a troubling history of toppling to a premature death because they don’t properly adhere to glass surfaces. This isn’t the case with the HOBOT-2S. Powerful suction helps the droid deftly move up and down a window without losing its grip.

State-of-the-art sensors detect when the bot gets too close to edges on framed and frameless windows. These sensors can even recognize air leaks around a window seal or the edge of frameless windows.

Backup Battery Power

If the power goes out or the plug disconnects, the HOBOT-2S has a backup battery that lets it continue cleaning for up to 20 minutes. An alarm will sound when this happens so you can reconnect the cord. For added protection, the HOBOT-2S comes with a 4.5m safety rope with a breaking strength of 200kg.

Wi-Fi Connectivity

Because it’s WiFi-enabled, you can use your smartphone to start, stop, pause, and resume the window cleaner at any time using the intuitive app.

This gives you total control of your window-cleaning bot right at your fingertips.

Extra-Long Power Cord

Some winbots are limited to cleaning glass surfaces that are right next to a power outlet. Because the HOBOT-2S has an extra-long power cord, it doesn’t suffer from this drawback.

Quiet Operation

The HOBOT-2S emits about as much noise as a washing machine on the spin cycle. This means it’s quiet enough that you’ll be able to work on the computer while it’s in the same room as you. However, you probably won’t be able to watch TV comfortably with this droid around.



Like all window-cleaning bots, it’s going to take longer to clean a window with this machine than if you did it yourself. Plus, unlike humans, winbots aren’t smart enough to see streaks.

While the HOBOT-2S does an excellent job cleaning glass surfaces, you’ll need to get up and move it to a different window at the conclusion of a cleaning cycle. This means that, unlike a robovac, you won’t be able to leave it unattended. Unfortunately, you can’t use the HOBOT-2S on frames with beveled edges or non-rectangular surfaces.

Final Verdict: Should You Buy The HOBOT-2S?

The HOBOT-2S is an impressive winbot that gets your windows radiantly clean without any effort on your part. This means it’ll free up time you can spend on less tedious things than doing housework.

Because it does such an excellent job at getting rid of crud from glass surfaces, I recommend that you buy the HOBOT-2S. Its superior performance, cutting-edge features, and labor-saving operation make it an excellent investment for anyone sick and tired of cleaning windows themselves.To see other robotic glass cleaning machines you might want to buy, check out our comprehensive guide.
