Common questions

Answers

Paint or clean the facade?
Cleaning instead of painting saves massive time - and budget; an average single-family home can be cleaned in 1 to 2 days depending on infestation. A professional facade cleaning costs only 20–40% of a complete new paint - you save up to 80% of the costs. Thanks to the latest telescopic lance technology, buildings up to 15 meters high can be cleaned quickly and gently directly from the ground. Expensive, elaborate scaffolding or bulky aerial platforms are not required. This protects the facade material, shortens the deployment time and ensures a like-new appearance with protection.
What cleaning agents does GEKO offer for special applications?
GEKO offers specialized cleaners for facades, stone, natural stone, concrete, roof surfaces, solar panels and graffiti. In addition, we provide solutions against algae and moss growth as well as products for protection and impregnation. Thus you get the right cleaning solution for many surfaces.
Which cleaning machines are available at GEKO?
Our range includes FIMAP and TSM cleaning machines for professional floor cleaning. This includes scrubber-dryers, sweepers, vacuum cleaners and cleaning robots. Upon request we also offer demonstration and promotional units.
What are EZ Shine Diamond Pads suitable for?
EZ Shine Diamond Pads are developed for cleaning, care, and gloss creation with water. They are suitable for scrubber-dryers and single-disc machines. Depending on the application, standard and high-performance variants are available.
Which industries does GEKO supply in Switzerland and abroad?
GEKO supplies cleaning professionals, trades businesses, and companies in Switzerland, Italy, and France. Our solutions are designed for professional use across various industries. We assist from product selection to implementation.
