I have taken a Masterbuilt high heat vacuum here to have repaired. They are the only place in the valley out of eight vacuum shops that can repair this specific make and model. The other vacuum shops in Scottsdale & Phoenix had no clue of where to begin in repairing one! Seriously it is just a high end shop vac that allows high heat to enter through it while getting the job done. I work for a Crematory where we use this type of vacuum to suck up the fine cremated remains off the retort floor. The staff has always been very helpful & prices are decent for repairs too!
