Specialized cleaning system for cleaning hard flat vertical surfaces

A specialized cleaning system for cleaning hard flat vertical surfaces, wherein the system comprises:

• a reservoir to store a cleaning fluid comprising water for cleaning;
• a first pump for pumping cleaning fluid from the reservoir for cleaning;
• an in brush dispenser for dispensing or spraying the cleaning fluid on the hard flat vertical surface which is to be cleaned;
• a brush for dispensing the cleaning fluid onto the hard flat vertical surface and scrubbing the cleaning fluid on the hard flat vertical surface and agitating dirt;
• a wiper for wiping the hard flat vertical surface;
• a wiper integrated suction for sucking contaminated or dirty cleaning fluid in to avoid spillage or running of cleaning fluid down the hard flat vertical surface;
• a separator for taking in an air-water mixture sucked by the wiper integrated suction from and separating the air from the contaminated or dirty water contained in the mixture;
• a filter for filtering the contaminated or dirty water to produce a filtered cleaning fluid;
• a second pump for pumping the filtered cleaning fluid back into the reservoir;
• and
• a suction pump mounted in the system which sucks the air from the separator and exhausts the air in the atmosphere through an exhaust;
• wherein the reservoir is arranged to mix the cleaned cleaning fluid with the cleaning liquid in the reservoir, and
• wherein the system is operable in direction from a top to a bottom of the hard flat vertical surface and in a direction from the bottom to the top of the hard flat vertical surface.
