When used correctly, the Hobot 2S robotic window cleaner will leave your windows spotlessly clean, making it a great pick for anyone who is looking to change how they clean their window!

Overview

We live in a world where technology is ever-evolving and things that were previously done by hand are now being automated. The introduction of robot window cleaners like the Hobot 2S is a good example of such. By using this bot, you can go about other duties whilst it cleans your windows for you.

It looks almost the same as its predecessor—the Hobot 298, but with better features. Equipped with a high-volume centrifugal pump, the Hobot 2S can effectively clean different types of surfaces. Aside from glass windows, you can use it on tile, marble, and any other smooth non-porous surface.

Also, this bot can clean both frameless and framed windows, which is great if you are someone who is after versatility. But that is not all, the Hobot 2S can safely clean windows with thin glass. The bot has a cleaning speed of 2.4 min./m². As such, it takes a longer time to clean windows compared to when you do it manually.

This shouldn’t worry you much since it’s a common problem with most robot cleaners on the market. On the plus side, the bot can work its way into corners, allowing for maximum coverage. That said, it won’t leave any undone patches, provided that you position the microfiber cleaning cloth correctly.

How the Hobot 2S Window Robot Cleaner Works

Like all robotic appliances, the Hobot 2S uses smart AI that is guided by a series of algorithms. This allows it to perform all its functions automatically with minimal human intervention. The Hobot 2S window robot cleaner is designed to move in a zigzag pattern to ensure the entire surface of the glass is squeaky clean.

It can accurately track its path as it moves vertically and horizontally along a given surface. The 6.5kg suction force created by the built-in pump keeps the Hobot 2S firmly anchored to the glass surface, so you won’t have to worry about it falling. Plus, it comes with a 4.5-metre safety cord to prevent such from happening.

For each cleaning cycle, the Hobot 2S will start by lifting dust particles and other particles, after which the ultrasonic nozzles nebulise the cleaning fluid into 15μm mist for easy removal of surface stains. However, the bot may have to make multiple passes when dealing with stubborn stains.

Bear in mind that the Hobot 2S is likely to leave streak marks on the surface of the glass if you don’t swap the cleaning cloth with a clean one, so ensure that you order extra cleaning pads. You will also have to move the bot manually to the next window once it’s done cleaning. The good thing is that the robot will send alerts via the Hobot app when it is done cleaning the assigned area.

Features

Dual Ultrasonic Spray System

Attached to the Hobot 2S robotic window cleaner are two spray tanks that convert the cleaning fluid into a dense mist for fast and efficient cleaning. Both tanks are strategically placed on each side for effective delivery of the nebulised fluid.

The fact that this unit has two tanks means it can cover more area with each pass compared to the Hobot 298 which only has one tank. In addition to this, the tanks are replaceable, so you can always buy new ones from Hobot in case the nozzles get damaged or clogged.

Auto-adjusting Pneumatic Pad

One of the main reasons why the Hobot 2S window robot cleaner can clean a wide range of surfaces is because it features an intelligently designed pneumatic pad that can automatically adjust itself, allowing for smooth movement. This feature also enables the bot to lift dirt faster, as it allows the microfiber cloth to stay in contact with the surface that you are cleaning.

Edge-leakage Sensors

The just mentioned sensors allow for fast and accurate detection of air leakages, especially when the bot is moving along the edges of the window. This in turn allows the Hobot 2S to make horizontal and vertical movements with ease without missing a spot.

Cleaning Reminder

Even though windows are always in sight, it’s very easy to forget about them when cleaning. And that is why the Hobot 2S has a function that will remind you to clean your windows after every three months. That way, the glass won’t be caked in dirt.

Uninterruptible Power System

To add to its list of features, the Hobot 2S has a backup battery that will provide you with up to 20 minutes of cleaning time during power outages. The UPS will automatically trigger an alert when the power is disconnected.

Memory Function

The Hobot 2S can remember the settings used in previous cleaning sessions, so you can pause the unit and it will resume work as usual when you hit the start button. This makes it convenient since you won’t have to reprogram the device repeatedly when cleaning multiple windows.

Voice Prompts

With the help of this feature, you will always know what the bot is doing. The Hobot 2S will tell you the mode that is currently in use and when it’s done cleaning.

Design

Similar to the Hobot 298, the Hobot 2S robot window cleaner has a square design, so it can easily get into hard-to-reach spots when cleaning rectangular windows. It is exceptionally lightweight, weighing just 1.3 kilograms. Underneath the Hobot 2S are two caterpillar belts that allow it to move on slippery surfaces without slipping.

This robot window cleaner gets its suction power from a brushless motor that is designed for performance. However, it’s a bit noisy, with a noise level of 70dB at 1 metre. You can access the available cleaning functions using the included remote control or a smartphone.

Moreover, the Hobot 2S firmware is compatible with both iOS and Android operating systems. It can be linked to all compatible devices via Wi-Fi. After this, you can customise the bot using the Hobot app. And since it comes with a 5-metre power cord, it can clean your windows with minimal restriction.

The 24cm x 24cm cleaning cloth on the Hobot 2S allows it to cover a large area with a single pass. To add to this, the cloth is made of a blend of high-quality cotton and microfiber to safeguard your windows against abrasion. You’ll be happy to know that the cleaning cloth is machine washable, so you can use it multiple times without making replacements.

Hobot 2S Robotic Window Cleaner Review Summary

The Hobot 2S is a great window-cleaning robot with advanced features that you can count on. It is equally versatile in that you can use it to clean other surfaces aside from windows. Nonetheless, it has a few shortcomings that you need to keep in mind before confirming your order.

For starters, there is a likelihood that it will leave streak marks on the surface of your glass window if you use the same microfiber cloth for dry cleaning and wet cleaning. Also, the bot is rather loud compared to most robot window cleaners in its class. All factors considered, the Hobot 2S is an innovatively designed robotic window cleaner that will deliver great results when used the right way.
