HOBOT R3 Robotic Window Cleaner


Powerful scrubbing action for sea spray, dust, and grime!

Powerful scrubbing action for sea spray, dust, and grime!

This is by far the best robot window cleaner HOBOT has released to date, backed by a 2-year warranty and 30-day satisfaction guarantee.

 To see the HOBOT R3 in action click the video link above.

Does the HOBOT R3 really work?


The best use of a robot window cleaner is regular maintenance to prevent the build-up of dust and dirt. Ideally, you should be using your R3 every 3 months. To help remind you, the HOBOT APP will alert you automatically every 3 months to clean your windows.

The process used for best results is dry clean to remove dust, change the pads and complete a wet clean to thoroughly wash and clean your windows.

Unlike other robot window cleaners, the HOBOT R3 can deal with salt spray and dirt road dust that often creates friction for other robot window cleaners.

But don’t take our word for it, the HOBOT R3 comes with a 30-day satisfaction guarantee.

How does the HOBOT R3 work?

Just turn it on, place it on the glass, and press play!

The HOBOT R3 will automatically work out the size of your window frame and start cleaning.

HOBOT’s inter-rotational movement imitates scrubbing the glass by hand when cleaning. Based on Newton’s third law of motion and coefficient of friction, when one cleaning wheel spins, another can stay in position to leverage the device and therefore the HOBOT R3 will move steadily in the opposite direction, cleaning the window automatically.

 You also have the option of controlling your HOBOT R3 via the app or remote.

Double spray jets!

Cheap copies either don’t have spray systems or sellers tell you to spray solution onto the glass, which defeats the whole idea of being robotic!

The new HOBOT R3 features a twin spray jet system ensuring there is more solution to remove dust and grime.

So all you need to do it place it on the window and press play!

70 RPM with 5kg suction force

The HOBOT R3 mimics human scrubbing action whilst applying 5kg of suction force with a powerful 90W Japanese Nidec brushless motor.

 Unlike cheap copies, it can continue to climb the window even when it is dirty due to superior components and software.

Up to 23sqm of glass cleaning per tank!

The tank may look small, but its ultrasonic spraying technology only uses 1ml of the cleaning solution to cover 1sqm, reducing the cost of cleaning solution and ensuring you fill the tank less.

One tank will cover up to 23sqm.

Multi-Surface cleaner

The HOBOT R3 is capable of cleaning:

  • Glass
  • Mirrors
  • Tiles
  • Splashbacks
  • Walls
  • Salt spray

Works on framed glass only.

Safety First and Analysis

Your HOBOT R3 completes a safety check and analysis of your window before it starts operating to ensure the best possible cleaning performance.

Latest software updates OTA

Unlike cheap copies that use closed systems, your HOBOT R3 updates software OTA (Over the air). So anytime HOBOT makes an update to improve performance you are sure to receive it without having to buy a whole new unit.

Voice prompts and creative voice

Your HOBOT R3 will speak to you and tell you what it needs, like when it requires more cleaning solution. If you want to get creative, you can also program the voice prompt.

What happens if the power fails?

Your HOBOT R3 has a backup UPS (uninterrupted power supply) which ensures your HOBOT R3 stays connected to the window for up to 20mins whilst you are alerted via the APP.

How long does it take to clean a window?

A window that is approx. 2sqm will take around 8 minutes. If you have the app on it will alert you when it has finished cleaning so there is no need to wait for it to finish.

I haven’t cleaned my windows in years, how will it perform?

I haven’t cleaned my windows in years, how will it perform?

Just like vacuuming, glass should be maintained on a regular basis. Untreated glass is porous and prolonged periods of not cleaning can mean mineral deposits (from water, rain, etc), dirt combined with the harsh sun can embed into the glass, making it difficult to clean for a human or a robot.

In circumstances like this, you may need to scrub windows first to remove mineral build-up and use the HOBOT R3 for regular maintenance or polishing after scrubbing

Do you have a cordless version?

No, cordless units are dangerous!

If the power or battery fails it will fall and potentially damage your home or injure someone.
