SERBOT-II HighRise Window and facde Cleaning System

The SERBOT -II High Rise. cleaning system is an unmanned semi-automatic machine used to maintenance clean non-porous, exterior

surfaces of midrise and high rise buildings. Smooth glass exteriors surfaces with frames less than 3 inches (7.5 cm) deep are the ideal

types of structures to be cleaned with this equipment. By design, the machine cleans the entire exterior surface including the mullions,

glass, seals, aluminum, marble, granite, Alumabond, Dryvit or any other non-porous materials used in the construction of the building.

Maintenance cleaning of the building surface is accomplished without the use any chemicals. Chemical application may be required in

restoration cleaning jobs. Using the combination of ultra pure water and the mechanical action of the rotating brush, the dirt is

loosened from the surface during the first pass of the machine as it climbs up the building. The pure water breaks down and holds

the dirt in suspension, releasing it from the surface. As the machine travels back down the same path, the rotating brush scrubs the

surface a second time with another spray of pure water to rinse the surface clean. The surface is allowed to air dry naturally. As there

are no dissolved solids in the rinse water, the surface will dry spot free.

The wash head is a self climbing device. It utilizes a Tractel Tirak. grip hoist for vertical movement along the wire rope used for

suspension from the roof top suspension rigging system. Note: Roof top suspension rigging system is not included with the SERBOT

High Rise. system. The Tirak. hoist is controlled with an industrial grade wireless remote control system rated for use up to 1500 ft

(450 meters) distance. Each machine has its own special frequency programmed into it so as to eliminate any interference from other

wireless devices.

The brush is made from special closed cell foam called Neo-Glide designed and used extensively in the car wash industry. This unique

material composition along with the 68 rpm rotational speed allows it to provide an aggressive scrubbing action without scratching the

surfaces. It also has a secondary polishing effect that enhances the gloss finish on the glass and other surfaces.

Machine stabilization is created by the use of Thruster technology. The Thruster fans create a powerful, positive force to keep the wash

head against the vertical surface of the building and to provide the correct, consistent pressure for the brush to operate properly over

the entire cleaning path.

Pure water production is from the SERBOT IRO. electric cart. This is a reverse osmosis and deionizing system that removes

99% of the dissolved solids from the potable water supply at the job site. The pure water is supplied to the wash head with a positive

displacement boost pump capable of providing the same consistent flow at any height without changing the nozzle pressure.

Application of the pure water to the building surface is done through a 316 stainless steel distribution manifold with SERBOT Rain Drop

nozzles. These nozzles create droplet sizes that are similar to rain. This ensures that 97% of the water reaches the building surface

even with wind speeds up to 20 mph (32K/hr). Each nozzle is protected by its own inline filter to prevent clogging.

Power and water is supplied to the wash head by an engineered support line system that ensures the proper operation for the given

designed length and demand. It has a nylon sleeve keeps the lines together and clean for easier use. A load suspension hanger

provides the correct method and strength for attaching the support line assembly to the bottom center of the wash head.
