I have yet to figure out how the accessories attach to the accessory caddy. But that's the much smaller issue. This vacuum has no power to the suction. I'm surprised by this, as I had bought it based on the many reviews saying exactly the opposite. It won't pick up the dirt on my car floor or the dog hair on the seat, nor will it pick up the lint and bits of paper in the rugs. I've yet to figure out what this is good for, and will be returning it this afternoon.
