Liectroux HCR10: A budget-friendly robotic window cleaner with automatic water supply

The budget-friendly Liectroux HCR10 window cleaning robot, priced at $130-$150, features an automatic spray function that sprays liquid before the wipes, improving cleaning performance and making it suitable for larger windows. Given the price and features, it's interesting to see how the Liectroux HCR10 compares to premium models. So, I'll test the robot below, then share my opinion on whether it's worth buying and whether the difference is significant compared to robots costing two to three times as much. So, let's get started!

Equipment

The window cleaning robot is packaged in a branded box like this:

In addition to the robot itself, which already has a safety rope attached, the delivery kit includes:

1. Power supply with extension cord.
2. A cable with an electrical plug for connecting the power supply to the network.
3. Operating instructions translated into Russian.
4. Two spare napkin holders.
5. 4 spare sets of microfiber cloths.
6. Bottle for pouring liquid into the robot's tank.
7. Remote control with batteries.

This model comes with a nearly complete set. If only it included a branded window cleaner, it would be perfect!

Appearance

Now let's take a look at the design of the Liectroux HCR10. This oval-shaped window cleaning robot has a cleaning module consisting of two rotating discs that hold round holders with cleaning cloths. Its body is only 68 mm high, making it suitable for use on windows with bars.

The top of the body features indicator lights indicating the robot's status and an on/off button. These indicators are also located on the back, allowing for visual monitoring of the robot's status when mounted on the outside of a window.

A nozzle for spraying water onto the work surface is located between the cloths. According to the manufacturer, it uses ultrasonic atomization. Above it is a small reservoir with a sealed valve, into which water or a special cleaning agent is added. The reservoir holds up to 30 ml of liquid, which is sufficient for 10-20 square meters of space.

The napkin holders are attached with snaps. In this regard, the design is standard.

Overall, the design of the Liectroux HCR10 is unassailable and I have no particular complaints about the build quality.

Technical specifications

Key features of the Liectroux HCR10 robotic window cleaner:

• Backup battery: Li-Ion, 500 mAh.
• Power consumption: 80 W.
• Suction power: up to 2800 Pa.
• Water tank: 30 ml.
• Battery life: up to 20 min.
• Dimensions: 295*145*68 mm.
• Weight: 1.03 kg.

Functional capabilities

Let's move on to an overview of the Liectroux HCR10's features. The window cleaning robot is controlled via a remote control. There's no option to connect to a mobile app, although I don't see much value in this option, considering you can't start the robot remotely and must always be present while it's working.

The remote control features three main operating modes: window sweep, left sweep, and right sweep. It also features manual control, start/pause, automatic water supply, and manual water supply. The only missing feature is a dual cleaning cycle; otherwise, all the features are standard.

Testing

Navigation and window cleaning quality

And finally, let's move on to the tests. You can simultaneously observe the robot's navigation and the quality of its cleaning of the outside of the window. I can say that the robot navigates well, doesn't slip, and is capable of cleaning both narrow windows as small as 38 cm wide and larger ones measuring 150 x 90 cm. And the cleaning performance itself is on par with premium-quality products. Here's a visual comparison of the window condition before and after:

You can see that it's truly effective and gets the job done. It's worth noting that I ran the robot twice on each section. The first time with dry wipes to collect the bulk of the dirt and dust. The second time, with the automatic water supply enabled. Here's the condition of the wipes after the tests:

Regarding the quality of window cleaning, there's only one caveat, typical of all robotic window cleaners: these devices aren't yet capable of effectively cleaning dirt in corners due to their design. But it will definitely help you get the bulk of the job done.

Application on other surfaces

This robot can also be used to clean tiled walls, shower stalls and mirrors.

It's even important to note that the Liectroux HCR10 detects the edges of frameless surfaces and can gently roll away from them without losing traction. That's a plus!

But on horizontal surfaces, it can't function properly. It can approach the edge and lose traction, causing a slip. This is worth keeping in mind.

Emergency mode

Let me explain how the Liectroux HCR10 operates in emergency mode. When disconnected from the power supply, the robot starts beeping and the red indicators on both sides of the body flash. This allows you to quickly detect the problem and remove the robot from the window.

By the way, I've often been asked whether the robot's suction power drops in emergency mode. Yes! At the very least, this robot barely holds on to the surface when running on a backup power source. Therefore, when using the robot to clean windows outside, especially in apartments, be sure to attach the safety cable to something stationary. For example, to a radiator or a table leg.

Noise level

As for the noise level, it ranges from 75 to 77.5 dB, which is standard. From the outside of the window, it won't disturb the room's occupants.

Personal opinion

The Liectroux HCR10 window cleaning robot was thoroughly reviewed and tested. In conclusion, I haven't noticed any difference in window cleaning quality between premium robots costing $400 or more compared to this unit. It's still not perfect, but it does provide significant assistance.

Yes, it doesn't have any additional features like app control, voice alerts, or more operating modes, such as dual-pass through the entire accessible area, but I wouldn't say they're particularly necessary or worth the extra cost. Another issue is the lack of official representatives on the market, and therefore a full warranty and service, for those who care. In this case, the only seller currently available is on AliExpress. But then again, the price.

As a result, on the screen you see the pros and cons that I would like to highlight:

Pros:

1. Budget cost.
2. Good navigation.
3. Small body height.
4. Automatic liquid supply.
5. Good quality window cleaning.
6. Capable of removing light stains.
7. Possibility of washing frameless surfaces.

Cons:

1. It doesn't wash away in the corners.
2. There is no full warranty or service.
3. No control via smartphone.

In my opinion, this is a rather interesting option. And while Liectroux robotic vacuum cleaners left me with mixed feelings, the Liectroux HCR10 robotic window cleaner definitely left no doubt.
