1. Change the filter bag when it is half-full. This improves the efficiency of the vacuum cleaner.
2. Remove, inspect, and clean the brush roll (beater bar). If there are signs of wear, the brush roll should be replaced. Remove hair, lint, and other items entangled on the roll.
3. Unscrew the cap on either end of the brush roll (if applicable) and remove any debris inside.
4. Make sure the brush roll spins freely. If not, lubricate the bearings if possible.
5. Check the belt for signs of wear — it should be taut. Typically, the belt should last about six months in commercial cleaning.
6. Remove any debris that may have accumulated in machine’s the air passages.
7. With the brush roll removed, look for cracks, unevenness, or worn spots on the interior casing of the vacuum cleaner. These could be signs of problems down the road.
8. Clean or replace filters, including HEPA filters, per manufacturers’ recommendations.
9. Wipe the outer casing of the vacuum cleaner; this helps prevent dust and contaminants from becoming airborne and clean equipment looks more professional.
10. Inspect cords and plugs. Some jansan service departments report repairing/replacing cords and plugs as the number one vacuum cleaner repair problem.
"A final tip is to have the vacuum cleaner checked every year," says Kennedy. "This [can] prevent a small issue from becoming a big problem."
