Hi Ajcleaner,i have so many problems with the rotovac that if it breaks down again im binning it.The speed control can be faulty causing it to trip.Also the trigger switch causes problems,same thing.You can by pass the speed control with a little rectifier .If i was you i would call Adam in Rotovac,you d get him now as there open in the states.Tell him your issues,hes a sound.
