The K900’s housing is pressurized by a powerful and compact fan. In the front area of the robot, at the dirt opening, an airflow is created by the negative pressure. This is the area where most of the dust is created, which is sucked into the robot by the air flow and passed through the air filter, almost 2 m2 in size. The size of the air filter corresponds to that of a ride-on sweeper. The filtered air is directed out of the robot through the sensors so that they are protected and freed from accumulating dust by the permanent air flow – the patented process ensures clear vision. Intensive tests have confirmed that the maintenance interval of the sensors is extended by a factor of 20 thanks to the air flow.
Performance and use
The K900 can filter up to 2.6 m³ of air per minute, which corresponds to 156 m³ per hour. This is 1,250,000 litres of air cleaned at eight hours of operation per day. Assuming that the robot operates eight hours per day, it is equivalent to the amount of air that 85 people breathe in and out per day. Constantly cleaning a room significantly lowers the concentration of dust particles in the air. Less dust settles on work surfaces, goods and machines, not to mention in the lungs of the employees. If wet cleaning had once been necessary to absorb the dust with the water, the K900’s dust binding usually eliminates the need for this. This saves water and chemicals, and no additional moisture enters the room.
The filter of the K900 is class «M» and is particularly suitable for cleaning industrial dirt. This also includes metal and wood dust particles, as well as normal house dust. To benefit permanently from the air filter, the filter must be serviced once a week, depending on the degree of contamination. The best way to do this is with a hoover, so the dust does not get back into the room. KEMARO offers a wall-mounted hoover for easy maintenance, with a mounting directly above the charging station of the K900. If the filter becomes unclean, the customer can replace it himself.
Care should be taken if the filter seal or filter membrane are damaged. If this occurs then filters, instead of ventilatingthe sensors with clean air, will send the dust tothe sensors, which can lead to malfunctions. Therefore, we recommend checking the air filter regularly.
