Vacuum Cleaner Maintenance Tips
If you own a cleaning business you know how crucial maintaining your vacuum cleaner fleet can be. Properly maintained vacuum cleaners can save valuable time and labor while keeping your clients floors looking great. Keeping your vacuum cleaner suction system void of debris and obstacles can increase the life of your vacuums motors in turn saving you money on internal parts and labor. A simple monthly inspection can save you time and money while increasing your vacuum cleaners efficiency.
The first thing to inspect on your vacuum cleaner is the cord. Check for any cracks or kinks in the cord make sure the cord connection to the vacuum is tightly secured into the vacuums body. A cracked or twisted cord can be an electrical hazard for your cleaning crew and people around the work area. If the cord is cracked and bare wire is exposed replace the cord immediately.
The next area to check on the vacuum cleaner is the filtration system. On a filter bag system check for any blockages on the incoming suction tube and the exhaust port. If your vacuum has any internal filters check for filter blockage and replace or clean them if they are dirty. Some vacuum cleaners have clips that old the filter bag in place, check to see if clips are cracked or bent and if so replace them immediately. If the filter bag is not sealed on the intake port debris could get into the vacuums motor and impede the performance of the vacuum cleaner.
If everything checks out in the filter compartment then its time to move to the underside of the vacuum cleaner. Lay the vacuum cleaner on the ground and roll it over to expose the beater bar and suction area of the vacuum. Make sure the intake suction tube is not blocked by debris that can cause a strain on the vacuum belt and prematurely burn out the motor. Check the beater bar for any cotton or fibers that might be wrapped around it. If material is wound around the beater bar cut it off carefully using a scissors while being careful not to cut the beater bar bristles. Spin the beater bar and listen for squeaks or grinding in the beater bar bearings. The beater bar should roll smoothly with light resistance from the belt. If the beater bar does not roll smoothly have a vacuum technician inspect and and if needed replace the bearings.
The final part of the inspection process is a quick look over the outer shell of the vacuum cleaner. Check for cracks or protruding parts and then roll the vacuum to see if it moves smoothly. If everything checks out then it should be good for another month of great service. On higher priced vacuum cleaners repair costs can amount to up to 500 dollars. A regular vacuum inspection can keep these costs down and your cleaning business running smother.
