Connectivity and storage are two issues that this addresses. The problem of connectivety is two fold. Constantly switching pads can be a frustrating process. This tearing free of the pad destroys the adhesion to the hook lock, causing the pad to spin free. The DF-2200 uses a connector that stays with the buffer which then connects to the backing plate with a hook lock. The pads attract dirt and debris which can ruin the paint finish. The DF-2200 utilizes a magnet on the backing plate that sticks to any metalic surface, such as the underside shelf of the tool cart or wall of a spray booth keeping contamination away.
