Outdoor greenhouse roof cleaners

Top Cleaner roof cleaner: the greenhouse roof and gutters all shiny and fresh again

The Top Cleaner is Van der Waay's top model greenhouse deck cleaner; a high-quality roof washer suitable for all Venlo greenhouses. Moreover, the machine is environmentally friendly because it only uses water to clean the glass. The Top Cleaner is also equipped with all imaginable safety devices.

Directing light in a greenhouse is getting more important, in every greenhouse. The roof has to allow through as much light as possible in the dark periods of the year. The Top Cleaner effortlessly removes dirt from glass and gutters without more ado, and without the use of environmentally damaging chemicals.

Safety first
Accidents on the greenhouse roof can have deadly consequences. Unfortunately, these accidents still occur. This could have huge consequences for the victim, the relatives and your company, and could lead to sky-high damage claims. That's why our machines do not only comply with the legally required (CE) requirements, but are also equipped with standard extra safety devices to protect your employees, such as:

  • a large-sized platform with a toe board to prevent slipping
  • a lockable ladder that blocks access to children or unauthorised persons
  • certified lifting points to lift the platform safely
  • certified security points so you are always secured to the platform
  • personal protective equipment, such as a harness, lanyard and fall arrest device
  • warning stickers in different languages, including symbols

You can also spray coatings like; Hermadix, Redusystems and Sudlac, fully automatic so no one has to ride along and no one can fall. Please also visit the page with photos of all safety devices of the Top Cleaner.

Versatile machine
The Top Cleaner greenhouse roof cleaner is available for every type of Venlo greenhouse. The machine is available from manual to completely computer-controlled. In the latter case, the windows automatically open and close when the greenhouse has to be washed.

With a small expansion, the machine can also be used to apply a layer of chalk or coating. We can also deliver rails and a movement platform if desired.
