Challenge Statement 4 – Automated External Facade Cleaning

Periodic external façade cleaning is carried out by manpower certified to work at heights, commonly with the use of a rope access, lift, gondola or scaffolding system. These methods mostly require the setting up of bulky equipment, clearance space for the equipment, training for the cleaners as well as on site supervision. The cleaners manually assess the cleanliness of the façade, before deciding on the usage of designated cleaning products to address specific stains.
