It sucks because it is the first car with a central vacuum cleaning system installed from the factory. The unit will operate for up to eight minutes with the engine turned off, or indefinitely with the alternator humming away. I watched at the New York International Auto Show as the engineer doused the hatch in Apple Jacks and then proceeded to suck them up.
For some, it may be a good idea. However, I would prefer the option of having an odds-and-ends bin installed in its place. Because one you have felt the juice of my 120V Black & Decker WalVac central vacuum system (now discontinued), you never go to any half-sucking solutions. But the Honda does suck pretty good. No word on CFMs yet.
