Yes there should be a bag with the hose and the attachments somewhere in the rig. That said, there are at least a few of us who gave up totally on the things and bought a shark or other good vac that really did the job. On our 2010 I tried buying the power beater and everything and finally gave up. Once I gave up I did the TV test and used the built in first to do a good job and then when over it with the shark. I had to empty the shark twice due to what it picked up and the built in didn't.
