Roomba's iRobot 205 robovac can go eight weeks without being emptied

The Roomba 205 DustCompactor Combo Robot is being advertised as "the industry's first onboard mechanical debris-compacting system." In other words, it squeezes dust and debris together like, well, a garbage compactor. This allows users to go eight weeks without having to empty the vacuum. It also eliminates the need for a dedicated debris bin. Otherwise, the 205 is a full-featured hybrid vacuum/mop.
