Question about Karcher RC3000 Bagless Robotic Vacuum
I found my RC3000 always cannot return to the base on first attempt. It is always 5cm, or even up to 10cm, deviated from the target charge-up metal plates and the sucking hole of the base. It needs to go to and fro in front of the base several times before it can hook up with the base by accident. It seems to me that the RC3000 is not well tuned.
Mine was doing the same thing. Turned out to be dust that had gathered inside preventing the electric eyes (ir sensors) from work well. Carefully using some lock ring pliers turn the three grey fasteners 90 degrees counter clockwise. Then lift off the yellow top cover. Using an air hose or soft brush clean the sensors sticking up from the circuit board. Be careful not to bend the out ones has they are not hard mounted. The also clean the inside of the IR windows on the yellow top cover. While your at it take the time to blow out all the dust from the unit. You should remove the inner screen prior to using compressed air so you can blow out the vac fan itself. About every six months I do this or when it starts to act weird. You should blow of all sensors on the base unit also.
