iBoto Win 389 Ultrasonic: A robotic window cleaner with a sprayer

The latest new product we've reviewed is the iBoto Win 389 Ultrasonic window cleaning robot. It's new to the market and costs around $190 at the time of writing. The key feature of this window cleaner is its water spray, which automatically wets the window as the robot moves to the right and up. This keeps the cleaning cloths moist throughout the entire cleaning process, which is especially important when cleaning large windows. Below, we'll take a detailed look at the iBoto Win 389, discuss its features and functions, and then share our opinion on whether this window cleaning robot is worth buying. So, let's get started!

Equipment

First, let's look at the package contents. The robot comes pre-attached with one pair of wipes and a safety tether. The box also includes:

1. Power adapter.
2. Cord for connecting the adapter to the network.
3. Extension cord.
4. Spare cleaning rings (2 pcs.).
5. Operating instructions in Russian.
6. Bottle for pouring liquid into the robot's tank.
7. Remote control with power supply elements.
8. Spare wipes (6 pairs).

The kit is complete. It has everything you need to comfortably operate the robot, which is a plus.

Appearance

Now let's take a look at the iBoto Win 389 itself. The safety cable is already installed on the robot out of the box. On the back, we see a carabiner for attaching the cable to a secure object. The power connector is located on the top cover. In the center, we see a handle with the company logo. Further along the cover, we see the power on/off button.

The top lid is removable. Underneath it is a hole with a sealed valve through which water is poured into the reservoir. The water tank holds 50 ml. The lid itself attaches to the body with magnets, which is very convenient.

On the underside of the robot, we see two rotating platforms with cleaning pads. The rings are easily attached to the base with clamps. Robot status indicators are located between the pads.

And right at the front there is a nozzle for spraying water onto the surface in front of the cleaning wipes.

It's important to note that the spray is droplet-based, not ultrasonic, like some similar products we tested previously. While droplets are less susceptible to being blown away by the wind, water can also run across the window if the wipes don't quickly disperse it. You'll see all the details in the tests below.

Functional capabilities

Let's move on to an overview of the iBoto Win 389's features. It can be controlled not only by the remote control but also via a mobile app. Let's start by looking at the capabilities of the included remote control.

The top left button switches between automatic and manual water spraying. The top right button is for manual spraying.

Below them is a joystick for manual control of the window cleaning robot and a button to start the automatic cleaning mode.

Below we see 3 modes of robot movement:

• Automatic movement left and down.
• Automatic movement right and down.
• Automatic up-down movement.

Below is a button to stop the washing process and a start/pause button.

The app can be downloaded using the QR code included in the instructions. It connects to the robot via Bluetooth. The app offers all the same features, but also allows you to select spray intervals: 5, 10, 15, and 20 seconds.

This is the robot's core functionality. It basically has everything that similar robots on the market have, so there are no complaints.

Testing

A video version of the review and all stages of testing has already been prepared and published. We recommend checking it out:

Now let's see how the iBoto Win 389 performs its primary function. First, let's test it on windows of different sizes. Fill the tank with water and attach the robot to the window.

He walked across the entire large window without any problem. There were no untidy areas, except for the corners.

Currently, no robotic window cleaner is capable of cleaning corners; at least, we didn't have any such models to test, due to the design features of this type of equipment.

The robot also cleaned standard, medium-sized windows without any problems, and it was even able to get through a narrow 35-centimeter window, which is a plus.

By the way, here's how the window spray system works, we'll show it close-up:

In our case, there were no streaks or significant stains left after going over the wetted area with wipes.

We also tested how well the robot cleans the outside of windows. Overall, the window cleaning performance was above average. While the robot can't remove stubborn, dried-on stains, at least without specialized cleaning products, it does remove dust and dirt that has accumulated over several months. It leaves minimal streaks, likely due to the neglect of the window. However, if you run the robot again with clean wipes, these streaks will disappear.

Here, check out the condition of the wipes after the robot passes over the window. We can see they've collected quite a bit of dirt and are already in need of a wash. Fortunately, there are six more sets available for further testing.

It's also worth mentioning the robot's emergency mode. If the power is disconnected, it can continue to operate for up to 30 minutes before it stops suctioning. However, during this time, you should detect the problem promptly and remove it from the window. When operating in emergency mode, the iBoto Win 389 beeps and flashes a red light.

As for additional applications, in my case, the robot couldn't move on tiled walls and started sliding down. This is most likely due to the glossy finish of the tiles, which are quite slippery.

However, the iBoto Win 389 can be used on horizontal surfaces. Perhaps you'll find a use for it. Sensors protect the robot from falls from heights.

Well, that concludes our testing. Let's move on to the conclusion.

Let's sum it up

The iBoto Win 389 Ultrasonic was thoroughly reviewed and tested. Here are some of the advantages that stand out after a thorough examination of this model:

1. Automatic spraying of liquid onto the window.
2. Good equipment.
3. Availability of warranty and service.
4. Affordable price.
5. The quality of window cleaning is above average.
6. Good navigation, the robot moves intelligently around the window and does not get stuck.
7. Control via remote control and mobile application.
8. Several operating modes.

As for drawbacks, there aren't any significant ones, but rather the typical ones for this type of equipment. The iBoto Win 389 doesn't clean out corners and can't scrub tough stains without pre-treatment. But you should be aware of this so you don't overestimate the robot's capabilities. I'd also add the inability to navigate glossy tiles, compared to similar products.

But for the money, this is a very interesting option to buy, and it deservedly enters our list. Best robot window cleaners of 2021.

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!
