Window Cleaning Machines and Pure Water Systems

Battery-Powered Window Vacuums from Kärcher

A battery-powered window vacuum is ideal for windows, glass doors, mirrors, and other smooth surfaces. The machine collects dirty water directly into a tank, reducing the risk of drips and spills during cleaning.

The Kärcher WVP 10 Advanced is designed for professional use and can be used on both vertical and horizontal surfaces. This makes it a practical choice for offices, retail stores, and other premises with large amounts of glass.

We also offer accessories such as narrow suction nozzles, microfiber cloths, and spray bottles.

Pure Water Systems from Unger

A pure water system allows you to clean windows using filtered water without adding traditional window cleaning detergent. The system removes minerals from tap water that would otherwise leave limescale spots when the water dries.

The Unger HydroPower Ultra uses ion-exchange resin to purify the water. It is used together with a water-fed brush and a compatible telescopic pole. This method is particularly suitable for exterior window cleaning and, with the right equipment and technique, can allow cleaning from ground level.

After cleaning, the glass is rinsed with purified water and left to air dry.

When Should the Filter Be Replaced?

The filter in a pure water system needs to be replaced when the ion-exchange resin no longer purifies the water effectively.

The Unger HydroPower Ultra includes a TDS meter that measures the level of dissolved solids in the water, displayed in ppm (parts per million).

Check the readings regularly and follow the manufacturer's recommendations for filter replacement. Filter lifespan depends on factors such as water quality and how often the system is used.

Frequently Asked Questions About Window Vacuums and Pure Water Systems

What is the difference between a window vacuum and a pure water system?

A window vacuum removes water from the glass after cleaning. A pure water system filters the water used to clean and rinse the windows. The best choice depends on the surfaces being cleaned and your preferred working method.

Do you need detergent with a Kärcher window vacuum?

The glass surface should be cleaned before the water is vacuumed away. Use a cleaning solution that is suitable for the machine and follow Kärcher's instructions for dosage and use.

Do you need window cleaning detergent with a pure water system?

Standard pure water window cleaning is normally carried out using purified water only, without adding detergent. For heavily soiled surfaces, additional cleaning may sometimes be required.

Do I need additional equipment for the Unger HydroPower Ultra?

Yes. To use the system for window cleaning, you will typically need a compatible water-fed brush, telescopic pole, and hose. Check what is included with the product and which accessories must be purchased separately.
