Complete your professional cleaning system
MELOX Hydropump - autonomous cleaning system
The MELOX Hydropump combines 200-bar high-pressure cleaning, reverse-osmosis water treatment, water heating and professional cleaning product dosing in one mobile unit.
Thanks to its integrated 400-litre water tank and electrically operated hose reels, the system allows professional operators to work independently on site.
It can be connected directly to your CHRONOS cleaning drone or professional cleaning robot.
Low-pressure spray gun for facade cleaning
The professional low-pressure spray gun offers a wide spray range of up to 6 metres, allowing larger facade areas to be treated efficiently.
Its lower operating pressure allows users to work from a greater distance from the facade, increasing control and reducing risks when cleaning difficult-to-reach areas.
