I have the newest 1005. It has the stage 3 new vac motors. It will trip the gfi. When I reset it it will constantly trip as soon as I plug the cord in. I’m thinking foam is getting in the vac and causing a short. I also have the Mytee booster that has the same two vac stage 3 vac motors and I’m not have an issue with that unit. Using the same psi and prespray.
