Pure water straight from the tap – for spot-free windows and vehicles. The mobile pure water osmosis unit turns normal tap water into almost mineral-free pure water (0–20 ppm). After rinsing, glass and paint dry without limescale spots – no squeegeeing or re-polishing needed.
- Pure water 0–20 ppm (in our test: 290 ppm tap water → 10–20 ppm)
- approx. 2.9 litres of pure water per minute, no tank
- Switches off automatically when the spray gun is closed – very quiet in operation
- No resin to buy: pre-filter every 2 years, membrane every 2–3 years depending on water
- Compact, approx. 8.7 kg – runs on a normal 230 V socket (with RCD protection)
- 2-year warranty on the system
In the set: Osmosis unit with conversion kit, 20 m flexible, expandable garden hose with brass connectors (Gardena type) and multifunction spray gun, Gardena quick connectors, cable protection box for the outdoor plug connection, German operating instructions and Swiss support.
All you need: a tap with a Gardena connection and a 230 V socket with RCD protection.
How to use it: Clean windows directly with the spray gun and a sponge or brush. Wash vehicles first as usual (e.g. with a high-pressure cleaner) and then rinse with pure water.
Pre-sale: Delivery from mid-December 2026. Limited to the first 20 sets.
Notes: The pure water is intended for cleaning and not as drinking water. Not suitable for connection to a high-pressure cleaner.
The difference
Spot-free drying in the sun – no chamois
Simply rinse with pure water and let it air-dry. No squeegee, no chamois, no polishing.

Normal tap water
Limescale spots visible from approx. 8 °dH (≈ 14 °fH)Limescale spots after drying
Tap water contains dissolved minerals. When it dries in the sun, fine white limescale dots and rings remain on paint and glass. From a water hardness of approx. 8 °dH (14 °fH), limescale spots become visible. Then only a chamois and polishing help.

Pure water 0–20 ppm
0–20 ppm · pure shine, spot-freeDries spot-free and shiny
After rinsing with pure water, practically nothing remains when drying. Paint and windows shine spot-free, even in full sun and without a chamois.
Your benefits
Clean result without polishing
Spot-free drying – even in the sun
In our test, the mineral content dropped from 290 ppm to 10–20 ppm. Windows and paint air-dried without limescale spots – even in the sun.
Plenty of pure water, no tank
Around 2.9 litres of pure water per minute straight from the mains. No tank, no waiting – just connect and go.
Switches off automatically
As soon as you close the spray gun, pressure builds up in the hose and the system switches off. It is very quiet in operation.
No resin to rebuy
Instead of expensive resin, you only change the filters every few years: pre-filter every 2 years, membrane every 2–3 years depending on the water.
2-year warranty
You get a 2-year warranty and personal advice from Switzerland – via WhatsApp, on Saturdays and Sundays too.
Compact & mobile
Approx. 8.7 kg, 230 V. The flexible 20 m hose lets you reach windows and vehicles easily.
How it works
Spot-free glass in three steps
Connect
Connect the tap with the Gardena connector, plug in the hose, place the waste line in a drain and plug in.
Clean
Clean windows directly with the spray gun and a sponge or brush. Wash vehicles as usual first, for example with a pressure washer.
Rinse with pure water
Finally, rinse thoroughly with pure water from the spray gun and let dry. Without dissolved minerals, no limescale spots remain.
A pre-filter (activated carbon) holds back dirt and chlorine. A pump then pushes the water through an osmosis membrane that largely retains dissolved minerals such as limescale. The retained minerals drain away with the waste water (approx. 0.5 litres per litre of pure water).
Applications
For windows, conservatories and vehicles
Windows and glass fronts
Clean exterior windows and large glass fronts directly with spray gun and sponge and rinse with pure water – dries streak- and spot-free.
High windows with a pole
For high windows, connect a standard water-fed pole with a Gardena connector. This lets you clean safely from the ground, without a ladder.
Conservatory and glass roofs
Clean large glass surfaces of conservatories and glass roofs from the outside and rinse with pure water – dries without a limescale film.
Rinse vehicles spot-free
Wash the vehicle as usual first, for example with a pressure washer. Then rinse with the osmosis system – paint and windows dry without water spots. The system can stay protected in the garage; only the hose is run outside.
Connection
Easy to connect
You need: a tap with Gardena connector + 230 V socket (with RCD protection)
Tap with Gardena connector
The system connects to a normal tap with the Gardena quick coupling. Plug the hose with spray gun into the pure water outlet.
230 V socket with RCD protection
The pump runs on 230 V from a normal socket. Always operate the system on a socket with a residual current device (RCD).
Cable protection box for the outdoor plug connection
Included in the set: outdoors, always place the plug connection in the protection box. This protects the plug from splashing water.
Rear
Connections on the back
Three hoses, clearly separated: water in, pure water out, waste water away.
Water inlet
Tap water from the tap (Gardena quick connector).
Pure water outlet
Osmosis water (0–20 ppm) to the spray gun.
Residual / waste water
Red hose: water with the filtered-out minerals.
Secure the red waste water hose firmly and lead it into a drain or wherever the water can run off.

Good to know
Operating notes
Not for drinking water
The pure water is intended for cleaning. Osmosis largely removes the minerals – it is not intended as drinking water.
Set up in a protected place
Operate indoors or in the garage. Protect from rain and frost and store frost-free.
Socket with RCD protection
Only operate on a 230 V socket with a residual current device (RCD). Outdoors, always place the plug connection in the cable protection box (included).
No pressure washer
Not suitable for connection to a pressure washer. Wash the vehicle normally first, then rinse with pure water from the spray gun.
Questions & answers
FAQ about the osmosis system
Your question is not listed? Message us on WhatsApp – we are happy to advise you, on Saturdays and Sundays too.
How pure is the water?
The pure water has 0–20 ppm dissolved solids. In our test, tap water at 290 ppm was purified to 10–20 ppm. Windows and car paint then dried without limescale spots.
How long do the filters last?
Replace the pre-filter (activated carbon) every 2 years and the RO membrane every 2–3 years depending on the water. A replacement filter set for both is expected to cost around CHF 190. You don't need to buy any resin.
Can you drink the water?
No, that is not intended. The system is designed for cleaning windows and vehicles. Osmosis largely removes the minerals.
When will it be delivered?
Delivery starts from mid-December 2026, in order of purchase. The pre-sale is limited to the first 20 sets.
What do I need?
A tap with Gardena connector and a 230 V socket with RCD protection, plus a drain for the waste water. A cable protection box is included for an outdoor plug connection. The system should be set up in a protected place, e.g. the garage.
Does it work with a telescopic pole?
Yes, the pure water outlet has a Gardena connector, so the system can be connected to standard water-fed poles with Gardena connectors.
What warranty is there?
You get a 2-year warranty on the system. If you have questions or problems, we help you personally, via WhatsApp on Saturdays and Sundays too.
Can I connect the system to a pressure washer?
No. The pure water is not suitable for feeding directly into a pressure washer. Wash the vehicle as usual first, for example with a pressure washer, then rinse with the osmosis system. It will then dry spot-free. Clean windows directly with the spray gun and a sponge or brush.
