Abstract

A vibrating air filter of a robotic vacuum comprising an electromagnet, a permanent magnet and an air filter. The electromagnet may comprise a metal wire and a power source connected to a first end of the wire. The power source may deliver electric pulses in alternating directions through the wire creating an electromagnet. The metal wire may be coiled around or placed adjacent to the permanent magnet and a second end of the wire may be connected to an air filter. Interaction between the magnetic fields of the electromagnet and permanent magnet may cause vibration of the wire and hence connected filter. Vibration of the filter may loosen any dust and debris latched onto the filter that may be shed into a dust bin of the vacuum.
