Every spring around the first part of May we give our vacuums a major tune up since they are the highest income generators on the property. New gaskets, new hoses, change the bags, change the motor brushes if they need it or not. The other car wash on the other end of town is .75 for 5 minutes and we are $1.75 for 3.5 minutes, we get comments all the time about how well our vacuums work, I’ve actually gotten complaints about to much suction. A little birdy told me that the KR VMK-19 motors are made by Electrolux. I haven't replaced a VMK-19 motor in years.
