Genio Windy W250: A window cleaning robot with an automatic water supply system

Greetings to all readers of the site! I received another robot window cleaner for review: the Genio Windy W250. This new 2021 model is essentially a twin of the very popular Xiaomi Hutt W66. Genio Collaborated with Xiaomi and released its own window cleaner. Its main advantage over its Chinese counterpart is the availability of full warranty support and the ability to order the robot from popular online and chain stores. The key feature of the Genio Windy W250 is its automatic water supply system, which increases cleaning efficiency. Below, I'll take a detailed look at the device's design, its features, how it performs its primary function, and, most importantly, whether it's worth the money. It's worth noting that the robot costs around $205–$220. So, let's get started!

Equipment

The window cleaning robot arrived in this branded box:

The kit includes:

1. Power unit.
2. Cord for connecting the power supply to the network.
3. Spare napkin (one is already installed on the robot).
4. A bottle for filling water into the robot's tank.
5. Remote control.
6. Operating instructions in Russian.

The package includes a standard set of accessories. The only important thing missing, in my opinion, is a special window cleaning fluid.

Appearance

Let's take a closer look at the Genio Windy W250's design. It's square, white and gray. Its dimensions are 231.5 x 231.5 x 76 mm. This compact height allows it to be used on windows with bars.

Attached to the handle is a non-removable power cord and safety tether. In the center of the body is the Genio logo, next to which is a robot status indicator and a single control button: Start/Pause. Next to the button is a hole with a sealed valve for filling with water. The reservoir holds up to 150 ml of water.

Let's take a look at the Genio Windy W250's underside. Window-protection sensors are installed in the corners. The robot moves using tracks, with ventilation holes for the main motor located between them. The red button turns the power on and off. A USB port for service is located nearby.

At the front, we see a panel with tiny holes through which water is dispensed in measured doses onto the surface. The cloth is attached to the robot with Velcro and has a fairly dense structure.

Overall, the robot's build quality is average, as is its price range. I have no particular complaints.

Technical specifications

The main characteristics of the Genio Windy W250, as stated by the manufacturer:

• Backup battery: Li-Ion, 650 mAh.
• Power consumption: 90 W.
• Battery life: up to 20 min.
• Minimum window size: 40*40 cm.
• The maximum window size is 500*500 cm.
• Dimensions: 231.5*231.5*76 mm.
• Weight 1.57 kg.
• Noise level: up to 65 dB.
• Travel speed: 2.5 min/1 sq.m.

Overall the characteristics are quite standard, let's move on!

Functional capabilities

Let's take a look at the Genio Windy W250's functionality. The window cleaning robot is controlled using the included remote control. It's important to keep this in mind, as it doesn't support app control.

The remote control has the following functions:

• Manual control of arrows.
• Start/pause.
• Dry cleaning mode.
• Turn voice notifications on/off.
• Wet cleaning mode.
• Turning the water supply on/off.
• Double pass mode of the available area.

Basically, the basic functionality is covered. It's also worth noting that the Genio Windy W250 speaks Russian.

Testing

A detailed video review with all the tests has already been prepared and published on the channel. I recommend watching the video:

Navigating large and small windows

And finally, let's move on to the tests. First, let's check how well the Genio Windy W250 navigates. It's worth noting that the navigation is handled by a six-axis gyroscope. It cleaned the large window without any problems, leaving no unexplored areas.

It can also fit through a narrow window, just 35 cm wide, despite the manufacturer's stated minimum width of 40 cm. That's a plus!

Window cleaning quality

Let's see how the Genio Windy W250 handles cleaning windows from the outside. Before starting the machine, I filled the reservoir with water. I didn't wet the cloth.

So, I was pleased with the quality of the window cleaning, removing dirt and dust. The robot does a good job, covering the entire accessible area, wetting the surface evenly, without leaving streaks or runs.

It's worth noting that the liquid isn't delivered to the surface in a stream, as shown in the promotional materials on the manufacturer's website. It's delivered in very small doses, drop by drop, as shown in the following diagram:

In any case, the implemented technology has proven its effectiveness compared to conventional window cleaning robots. As for the Genio Windy W250, the only criticism is that, due to the sensors installed in the corners, this robot doesn't completely clean corner areas, just like its counterparts.

Here's the cloth after washing the window. As you can see, it's collected dirt and dust:

Other features

I'll also explain how the Genio Windy W250 operates in emergency mode. When the power goes out, the robot emits a voice alert and the indicator light starts flashing red. You'll have about 20 minutes to react promptly and remove the robot from the window. Remember to secure the safety tether to a stationary object to prevent the robot from falling from a height.

It's also worth noting that the Genio Windy W250 can clean not only glass but also other vertical surfaces, such as tiled walls. This is a plus.

Oh, and by the way, this window cleaner can work on frameless windows.

Finally, I'd like to mention one more feature of the device: it can even operate on horizontal surfaces. Perhaps you'll find it useful in this area as well.

Let's sum it up

The Genio Windy W250 was thoroughly reviewed and tested. I'll summarize and share my personal opinion of the robot after using it. I liked the following:

1. Technology of automatic water supply to the surface.
2. The quality of window cleaning is above average.
3. Good navigation.
4. The compact size of the body allows the device to be used on windows with bars.
5. Possibility of washing frameless windows.
6. Work on small windows.
7. The robot's versatility. It can work on both vertical and horizontal surfaces. It's also suitable for cleaning not only windows but also glass doors or bathroom tiles.
8. Availability of warranty and service support.

As for any shortcomings, no critical ones were found. I can only highlight a few comments:

1. The corners remain unwashed.
2. There is no provision for control via an app.
3. Not capable of removing difficult stains.

Overall, the device is on par with most similar devices in the sub-$250 price segment. The Genio Windy W250 will handle seasonal window cleaning, removing dust and dirt, so I have no compelling reason not to recommend it. For the price, it's a good option and will likely be a favorite. Rating of the best window cleaning robots, which will be prepared a little later.

On that note, I'd like to end this review. If you have any questions, please ask them in the comments. Happy shopping, everyone. Bye!
