Maintenance Information Basics
Taking care of a central vacuum unit is quite easy. The only required maintenance is changing or cleaning the filter and dumping the debris. If the top doesn't lift off to access a filter then twist or unlatch the base to perform the maintenance. There is nothing to lube or oil on the central vacuum system including the motor. For more maintenance tips, visit the motor page for your brand in the yellow bar below.

Maintenance Information Basics
Taking care of a central vacuum pipe is easy. It rarely, if ever, requires maintenance. However, there is a way to clean out and deodorize the hose and pipes using
Free Flow Central Vacuum Maintenance Sheets. Maintaining the inlet valves is done as needed. Parts are not sold separately so if a door breaks
replace the entire inlet valve. Here is how to
fix air leaking inlets.

Maintenance Information Basics
There is nothing to lube or oil on the vacuum cleaner, but the fibers wrapped around the brush roll of the vacuum cleaner head should be cut out and removed on a regular basis. For vacuum hose maintenance, the most important tip is to disconnect the hose from the wands and hang it up or lay it on the ground. Keeping it connected puts pressure on the hose as it bends down, which may cause a tear over time.
