Abstract
Permanently installed vacuum system hose is stored on a hose reel device that includes a retraction spring and a hose guide mechanism that ensures the hose is placed in a tight, space efficient pattern of one or two rows of hose. This efficient storage pattern is accomplished without operator effort. A ratchet mechanism allows hose to be drawn off the reel on demand. When the ratchet is disengaged, the vacuum hose is drawn back onto the reel.
