News » 30.06.2026 - Renewed cover washer now cleans more square meters of greenhouse roof
A common frustration among greenhouse growers is that the most difficult sections of a glass roof tend to remain unwashed. With existing machines, this typically results in dirty strips at the beginning and end of each bay, or requires additional manual labour. Dutch manufacturer Besseling Techniek, based in Heerhugowaard in the Netherlands, says its new Roofmaster 2 roof-washing machine addresses this problem directly.
The fully redesigned roof washer was presented at GreenTech Amsterdam, where it received positive responses from both domestic and international visitors. Ronald de Vos, managing director of Besseling Techniek, noted the reaction came as no surprise. "The new Roofmaster 2 offers a demonstrably greater reach than existing solutions, representing a step forward in light transmission, reliability and ease of use." The machine is designed for washing, maintaining and coating greenhouse roofs.
Besseling Techniek has been active in the international agri- and greenhouse horticulture sector for 35 years. The company supplies Roofmaster roof-washing robots worldwide. "Together, our systems wash and coat more than 2.5 billion square metres of glass greenhouse roof annually," De Vos said.
The redesigned Roofmaster attracted considerable attention at GreenTech Amsterdam, Ronald de Vos observed.
Full reach: no more compromises
The key innovation lies in the repositioning of the main brushes, which have been moved forward to allow the full bay, from start to finish, to be washed automatically. This extends coverage by approximately 1.5 metres per bay compared to previous models.
According to De Vos, this resolves a widely reported market demand: no more dirty strips, no post-treatment, and no need to send workers onto the roof. "The Roofmaster 2 delivers a consistently clean result across the entire greenhouse roof, every time it runs."
Gutter cleaning has also been improved. The Roofmaster 2 comes standard with two integrated V-shaped gutter brushes with a greater reach than before. "Dirt accumulation in and around the gutter is removed more effectively, which not only contributes to a cleaner roof but also to better water drainage and a longer roof lifespan," De Vos said.
More light, more yield, more appeal
A clean greenhouse roof has a direct and measurable impact on production. Maximum light transmission translates to higher yields, while a well-maintained greenhouse also projects a professional image. "With the Roofmaster 2, this is no longer a one-off action but a structural and reliable process," De Vos said.
Built smarter, easier to maintain
The internal design of the Roofmaster 2 has also been thoroughly revised. "The internal layout is more straightforward, components are more accessible, and maintenance has become considerably more user-friendly. New, modern parts contribute to greater operational reliability and long-term durability," De Vos said.
Improved cloud connectivity allows the machine to be monitored and supported remotely. "This enables faster diagnosis, more efficient maintenance and improved service delivery, meaning less downtime, less maintenance and maximum availability throughout the season."
Automation as the logical next step
Safety and labour pressure are playing an increasingly important role in greenhouse horticulture, and manual roof cleaning is coming under growing scrutiny. The Roofmaster 2 is designed to fit this trend. "We offer an automated solution that consistently delivers quality, independent of conditions and without risk to personnel," De Vos said.
