The vacuum dock is a great idea, and one ive ranted about for years. <br><br>A major limitation on smart vacuums and the like is limited holding capacity, meaning often daily emptying of the device but more importantly limits these devices minimum size (as they need a certain size capacity to be of use without needing multiple emptyings for a single task)<br><br>This hub system would allow for even much smaller "mouse-bots" that could just frequently re-dock to empty their chambers.
