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. ## Claims ### Claim 1 A method to prevent accumulation of particulates on an air filter of a robotic vacuum comprising: delivering, by a power source, electric current pulses in alternating directions through a metal wire connected to the air filter; and, vibrating, by placement of a permanent magnet in a location wherein a magnetic field of the permanent magnet and an magnetic field of the metal wire can interact, the metal wire and connected air filter. ### Claim 2 (depends on 1) The method of claim 1, wherein a control system of the robotic vacuum can adjust the frequency of electric current pulses. ### Claim 3 (depends on 1) The method of claim 1, wherein the permanent magnet has two poles. ### Claim 4 (depends on 1) The method of claim 1, wherein the metal wire is coiled around the permanent magnet. ### Claim 5 (depends on 1) The method of claim 1, wherein the metal wire is located adjacent to the permanent magnet. ### Claim 6 (depends on 1) The method of claim 1, wherein the control system of the robotic vacuum can control the duration of vibration of the air filter. ### Claim 7 (depends on 1) The method of claim 1, wherein the control system of the robotic vacuum can activate and deactivate vibration of the air filter. ### Claim 8 (depends on 1) The method of claim 1, wherein the control system of the robotic vacuum can activate vibration of the air filter after each time a predetermined number of operational hours of the robotic vacuum have been completed. ### Claim 9 (depends on 1) The method of claim 1, wherein the control system of the robotic vacuum can activate vibration of the air filter after a predetermined amount of particulates accumulate on the air filter. ### Claim 10 (depends on 1) The method of claim 1, wherein particulates are shed from the air filter into a dust bin of the robotic vacuum when the air filter vibrates. ### Claim 11 A vibrating air filter apparatus of a robotic vacuum comprising: a metal wire, wherein a first end of the metal wire is connected to the air filter and a second end of the metal wire is connected to a power source; a power source, wherein the power source is configured to deliver electric current pulses in alternating directions through the metal wire; and, a permanent magnet, wherein the permanent magnet is placed in a location wherein a magnetic field of the permanent magnet and a magnetic field of the metal wire can interact and cause vibration of the metal wire and connected air filter. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein a control system of the robotic vacuum can adjust the frequency of electric current pulses. ### Claim 13 (depends on 11) The apparatus of claim 11, wherein the permanent magnet has two poles. ### Claim 14 (depends on 11) The apparatus of claim 11, wherein the metal wire is coiled around the permanent magnet. ### Claim 15 (depends on 11) The apparatus of claim 11, wherein the metal wire is located adjacent to the permanent magnet. ### Claim 16 (depends on 11) The apparatus of claim 11, wherein the control system of the robotic vacuum can control the duration of vibration of the air filter. ### Claim 17 (depends on 11) The apparatus of claim 11, wherein the control system of the robotic vacuum can activate and deactivate vibration of the air filter. ### Claim 18 (depends on 11) The apparatus of claim 11, wherein the control system of the robotic vacuum can activate vibration of the air filter after each time a predetermined number of operational hours of the robotic vacuum have been completed. ### Claim 19 (depends on 11) The apparatus of claim 11, wherein the control system of the robotic vacuum can activate vibration of the air filter after a predetermined amount of particulates accumulate on the air filter. ### Claim 20 (depends on 1) The apparatus of claim 1, wherein particulates are shed from the air filter into a dust bin of the robotic vacuum when the air filter vibrates.
