Full HOBOT 2s window robot cleaner Review
How it works
HOBOT 2s window robot cleaner is a window cleaning robot that uses high-frequency ultrasound technology to clean glass surfaces. It’s designed for all types of glass no matter what thickness they are. The Hobot 2s has an algorithm that prevents it from falling off high places or balconies with its anti-falling control feature. It can also be controlled by a smartphone and it uses smart laser sensors to detect the edges of your windows easily.
This robot cleaner uses microfiber cloths that don’t leave streaks or lint behind and will make sure that the windows are spotless every time.
Performance
To provide unrivaled cleaning results, the ultrasonic spray nozzles nebulize water into 15nm fine mist particles. While the powerful suction enables HOBOT to firmly stick on vertical rough surfaces while removing dust and dirt effectively, the 7 kg ascending power allows HOBOT to move steadily up and down without skidding.
The cleaning cloth is kept in balance by an auto-adjustable pneumatic pad that adjusts the driving force automatically. The Hobot 2s is a step above its previous versions in terms of performance, thanks to the updates that the company has made.
Limitations
The Hobot 2s does a good job cleaning your windows. The only downside is that you’ll have to manually move it for some sections and it can be a little noisy. Also, it does take some time to finish up tasks that can be done in less time manually.
Ease of set up and use
The overall setup is easy. Just plug in the adapter to the power cord whilst making sure the extension cord is connected to the adapter. Then insert the connector in the power jack of the device and it is good to go. The UPS should also be charged separately before use. Finally, apply the cleaning cloth to the device correctly.
With the touch of a button on its remote control, this robot will automatically clean every inch of your window from top to bottom. You can even set it up so that the robotic cleaner cleans while you’re at work or out for dinner!
Reliability
The design of the Hobot 2s in itself has seen an upgrade to its previous models and is highly reliable. The position of the cleaning cloth is automatically adjusted by an auto-adjustable pneumatic pad, maintaining the force between caterpillar treads and the cleaning cloth in balance.
Most Hobot products come with a one-year warranty and the 2s is no exception.
Ongoing Maintenance
On the maintenance part, the cleaning cloth needs to be taken care of as it is the most important part of this robot cleaner. Make sure you clean the cloth properly after each use and do not leave the water to dry on it as this can cause a stain on the cloth. The Hobot comes with an adapter that needs to be plugged in at all times as well as a UPS.
Replacing the water tank timely is also recommended which you can do easily thanks to its replaceable water tank. The other important area that requires cleaning is the caterpillar belt. This is important to make sure your device runs on a clean belt without skidding. This needs to be done before each use.

Extra Purchases and ongoing costs
With a cleaning cloth & a water tank already included, there are no extra purchases that need to be made for this device. However, there may be a need in the future to replace the Ultrasonic spray nozzle. This may happen due to the nozzle being clogged which will cause problems and the water spray may not work properly. This is when a replacement will be needed & your local authorized dealer can help you with that.
A couple of alternatives to consider
Hobot 298 & Winbot 880 are the two alternatives to consider other than the 2s. Here’s a quick overview of both products.
HOBOT-298 Window Robot Cleaner provides an innovative solution for cleaning high windows while operating automatically. The product attaches microfiber cloths at both sides of its body so when spraying water or detergent on the surface of the window, dirt and other particles are removed from it using washing action and then dried by microfiber cloth after cleaning.
This ensures easy operation for users as they only need to operate one button to start cleaning their desired area while avoiding any physical contact with dirty surfaces directly using hands or other tools which might cause health issues.
The Winbot 880 is equipped with optimized navigation technology that will clean every inch of your surface quickly and efficiently. It has multiple safety features so you don’t need to worry about falling off a ladder trying to clean your windows anymore!
With 2800 pa suction power, this window cleaner is also equipped with an emergency battery with a 30 min backup in case of an outage. Also has the same advanced edge detection technology that the 2s has to help it navigate through the edges. Has a four-stage system that programs it to go over a single area four times to make sure they are thoroughly clean.
