I have never posted here before - and this may be completely irrelevant - Vacuum cleaners can be very problematic for certain power protection circuits (in the inverter for example) and NOTHING to do with current limits. I ran into this issue when I changed all my circuit breaker to combined AFCI / GFCI breakers. It is specifically the AFCI (Arc fault interruption) that look at the noise on the line to interrupt the circuit. Our old Vacuum just would not work, bought a new Dyson .. did the same (my welders/ 3kW table saw were all happy.
I eventually got a replacement set from GE (which still was not good) and went and bought Siemens ones that work.
Moral of the story may be the inverter that has built in AFCI circuitry.
