Dirt Devil CV1500 RV Central Vacuum Full System has 2 hoses, the main hose use to vacuum and the installation hose to the inlet door. If your main hose is completely unclogged you can check to see if there's suction at the inlet door. You may also want to check the installation hose to the inlet to make sure that this hose is not clogged. If unit was mounted directly to inlet door then the clog is in the intake port and will need to be cleared with maybe a hanger bent like a hook to fish out.
