Hutt E+ – Battery for window cleaning robots

Frequently Asked Questions About HUTT Window Cleaning Robots

1. Can it be used on insulated glass (double or triple glazing)?
Yes. HUTT robots work on single, double, and triple-glazed windows. Check your specific model’s specifications to ensure compatibility.

2. Can I see the robot in action?
Yes. Each model (for example, the HUTT W9) has video demonstrations showing how the robot performs on different types of windows and what results you can expect.

3. Does it really work? Does it leave streaks?
When used correctly, HUTT robots do not leave streaks on glass. Customers using models like the C7 report that their windows remain perfectly clean and shiny.

4. Can the robot fall off the window?
Safety is a top priority. Every HUTT robot is equipped with:

• strong vacuum suction for firm grip;

• a backup battery that keeps it attached during a power outage;

• a safety rope to prevent falling.

When used properly, the risk of falling is minimal.

5. What results should I expect?
Keep in mind that the robot is an assistant, not a magical solution. If your windows are very dirty, several cleaning passes may be needed. With regular maintenance, the results are excellent – spotless, crystal-clear windows with no effort.

6. How can I be sure of the quality and support?
HUTT is an international brand with official distribution in Bulgaria. All products come with warranty and service support. We are constantly improving customer communication and after-sales service.

7. What if I’m not satisfied?
We understand that every customer has different expectations. If you’re not satisfied, you can contact us for assistance, advice, or a return according to the warranty terms.

8. How should I prepare the cleaning solution?
For best results, use a mixture of clean water and a few drops of mild glass cleaner. Avoid strong chemicals or abrasive detergents, as they may damage the pads and the mechanism.
The official HUTT cleaning spray is optimally balanced, but a homemade solution also works well.

9. How do I clean very dirty windows?
If the windows are heavily soiled (e.g., dried mud or dust):

• first, run the robot dry (without liquid) to collect dust and larger particles;

• then, fill the tank with water and cleaner and run it again for deep cleaning and shine.

This prevents smearing and ensures a much cleaner finish.

10. How often should I change the cleaning pads?
To keep your windows spotless and streak-free:

• wash or replace the pads after every 2–3 windows (or one large, heavily soiled window);

• always use dry and clean pads for each cleaning cycle, as damp or dirty ones may leave marks.

For frequent use, it’s best to have an extra set of spare pads ready for replacement.
