Gadget W200: An affordable robotic window cleaner with a water spray function

The latest robotic window cleaner we've reviewed is the Dadget W200. This model's key feature is its automatic water supply during cleaning. This improves dirt removal and keeps the cleaning cloths moist for longer, which is essential when cleaning large windows. Below, I'll thoroughly test the Dadget W200, highlight its pros and cons, and then express my opinion on whether this robotic window cleaner is worth buying. The price at the time of writing is between $80 and $120. So, let's get started!

Equipment

The window cleaning robot arrived in this branded box:

The package includes:

1. Power supply with 4-meter cord.
2. Cable for connecting the power supply to the network.
3. Remote control with batteries.
4. 18 spare wipes. 2 more are installed on the robot itself.
5. Two spare napkin holders.
6. Bottle for filling water into the robot.
7. A spray nozzle on a bottle for spraying cleaning agent onto wipes.
8. Operating instructions in Russian.

The package is good. I was pleased with the large number of spare wipes. Let's move on!

Appearance

Now let's look at the design of the Gadget W200. It's oval-shaped, so the cleaning module consists of two round pads.

The actual height of the case is 10 cm, although the manufacturer states 91 mm in the instructions.

The robot comes with a safety tether and carabiner attached out of the box. On top is a threaded power cable connector and a 50 ml water tank.

A nozzle is located on the side to supply water to the surface in front of the wipes as the robot moves in one direction.

The body features recesses for easy gripping when installing and removing the robot from a window. On the other side is a mechanical power on/off button and robot status indicators.

The robot's status indicators are also duplicated on the underside. The wipes are of the familiar design. The holders are easily removed and reinstalled from the robot.

Technical specifications

The main characteristics of the Gadget W200, as declared by the manufacturer:

• Backup battery: Li-Ion, 650 mAh.
• Power consumption: 80 W.
• Battery life: up to 20 min.
• Water tank capacity: 50 ml/h
• Dimensions: 295*148*91 mm.
• Glass cleaning speed: 1 sq.m./4 min.
• Maximum size of one glass: height 4 m, width 4 m.
• Minimum size of one glass: height 50 cm, width 50 cm.
• Noise level: up to 77.5 dB.

I measured the noise level myself. If the robot is indoors, the noise level is around 77-77.5 dB. However, if it's installed outside and the window is closed, the noise level will depend on the soundproofing of the windows. In my case, it was 58.5-59 dB.

The W200 is louder than its predecessors. W100 And W120.

Functions

The window cleaning robot is controlled using the included remote control. It features buttons for automatic fluid supply, manual spray, stop, start/pause, manual robot control, and three automatic modes: up-then-down, left-down, and right-down.

Testing

A detailed video review of the Gadget W200, including all tests, has already been prepared and published on the channel:

Navigation and window cleaning quality

And finally, let's move on to the tests. First, we'll check how the Gadget W200 handles its primary task – cleaning windows from the outside. We'll also be able to evaluate its navigation. The robot's first pass over the windows collects all the dirt. It's recommended not to wet the wipes to reduce the risk of the robot smearing dirt across the glass. I also disabled the automatic water spray.

For the second pass, you can fill the robot with water, spray a little water or cleaning agent onto the wipes, and turn on the automatic liquid spray.

Let's compare the condition of the windows before and after:

Here I will just note that the weak point of all window cleaning robots without exception, including this one, is that corners remain unwashed due to the design features of the cleaning module.

Otherwise, the window cleaning quality is on par with similar products. It also navigates narrow windows without a problem! No complaints about the navigation!

Application on other surfaces

This robot can also be used to clean tiled walls, shower stalls, and mirrors. It's even worth noting that the Dadget W200 can gently roll away from the edges of frameless surfaces without losing traction. This is a plus! However, the manufacturer does not recommend using this model on frameless surfaces.

But for those interested, this window cleaning robot can't function properly on horizontal surfaces. Its movement algorithm is flawed.

Emergency mode

Let me explain how the Gadget W200 operates in emergency mode. When unplugged, the robot starts beeping and a red indicator light flashes on both sides of the robot. Here's how it works:

A light indicator and a beeping sound will allow you to promptly detect the problem and remove the robot from the window.

Let's sum it up

The Dadget W200 window cleaning robot was thoroughly reviewed and tested. I'll summarize and share my personal opinion of the robot after using it. Here's what I liked:

1. Good quality window cleaning.
2. Automatic spraying of cleaning liquid onto the surface.
3. Good navigation.
4. Work on small windows.
5. The robot's versatility. It's suitable for cleaning not only windows, but also glass doors, mirrors, and wall tiles.
6. Good equipment.
7. Affordable price.
8. Warranty and service availability. It's worth noting that Dadget window cleaning robots come with a full 3-year warranty!

As for the shortcomings, the following were found:

1. It doesn't wash into the corners.
2. Does not work on horizontal surfaces.
3. The noise level is slightly higher compared to similar products.

Overall, the first comment is typical for all robotic window cleaners. The rest are specific to this model. In any case, considering the price, which starts at $80, and the automatic water supply feature and warranty, I consider the Dadget W200 a good option. It cleans windows well, so it will be a great helper for many!

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