According to David VanGorder, the president of Doyle Vacuum Systems LLC, if new carwash owners take the time to perform simple upkeep tasks, their vacuums should perform well long into the future.
“Keep the unit clean, inside and out,” he said. Empty the accumulated dirt on a regular basis, not just when it’s full. He added that you should clean the outside of the vacuum as well, to keep your vacuums looking nice and desirable to customers.
“Whenever you empty your vacuum,” VanGorder said, “inspect the condition of the dirt door and filter door gaskets to ensure that a good seal is being made when the vacuum is running.”
During the filter inspection, VanGorder also said to “inspect the condition of your vacuum hose, be sure it is not cracked or plugged, and be sure it does not look like it just got dragged through the mud.”
Depending on the vacuum use, either bi-weekly or monthly, VanGorder said you “should remove the vacuum dome and inspect the vacuum motors, motor brushes, and motor gaskets to ensure that everything is functioning properly, [and] that the brushes have adequate life remaining." It is also important to make sure that the gaskets are providing a good seal to the tank.
