A central vacuuming system can be a convenient way to assure regular upkeep of the RV flooring and upholstery.  Designed with concealed tubing that leads to a canister in the bay, the central vacuum system eliminates the need for a mobile vacuum cleaner that can take up cargo space.  In many model motor homes a central vacuum system can be added as an after market installation.

To operate the central vacuum system, locate the flexible hose, generally stowed in an interior closet or a pull out drawer under the sofa.  Plug the hose into the inlet, which is generally situated in the center of the vehicle, such as at a galley baseboard.  If the RV is plugged into less than 30-amp shore power, turn on the generator while running the central vacuum system.  The central vacuum system runs approximately 10.2 Amps.  Empty dirt and debris from the canister located in a cargo bay at least one time per month.  More often if you are traveling with pets that have been exposed to fleas.

If the unit fails to operate, or ceases to run soon after starting, inspect the circuit breaker at the fuse panel.  Insufficient power to the RV, or running too many items at one time can cause a fuse to blow.

Regularly replace the dust bag to insure continued efficiency.  Central vacuum units featuring a filter located in the canister will require regularly cleaning of the filter to remove dust and debris.  Rinse the filter in warm water and allow to air dry.  If the filter is worn or damaged, contact the vacuum manufacturer to obtain a new filter.  Use care to securely replace the filter after each cleaning.

Clogs in the system can cause a lack of suction.  Disconnect the hose from the wall receptacle and place a hand over the outlet to check for suction.  If you think the problem may lie with the hose, start by inspecting the vacuum head for stuck debris.  It may be necessary to snake the hose to remove clogs, but use caution to avoid puncturing the hose.

Lack of suction at the inlet may indicate a clog in the wall tubes.  Start by carefully examining the inlet with a flashlight for any signs of debris build up.  If the problem appears to lie deeper inside the system, run a plumber’s snake through the system and try to capture the clog.  In some cases you can also remove a clog by hooking a portable vacuum to the inlet and attempt to suck the debris out, or reverse the process and blow the clog into the canister.

Reduce the risk of clogging the central vacuum system by picking up clutter and large debris before vacuuming the carpets.  Shake throw rugs outdoors and set them to one side until after the carpet is cleaned.  Begin by vacuuming the furniture and valances, paying particular attention to crevices in furniture where pet hair builds up.  Use attachments to vacuum along the baseboards, as well as the overhead air conditioner vent and furnace grill.
