What should I do if my vacuum trips my AFCI device?
Plugging the vacuum into a surge suppressor with EMI filtering, should prevent the vacuum from tripping the breaker. However, if the vacuum is overloading the circuit, no filter will help.

When I run my vacuum sweeper / paper shredder / treadmill / etc. it trips my AFCI.
Eaton’s AFCI has been designed to work with devices with motors that are within the FCC standard for noise. Even though these devices have been manufactured to the FCC’s standards, after frequent use wear within the motor can create noise which trips the AFCI. To mitigate the noise generated by these devices, you may use a surge plug or surge strip
