The Create 2 from iRobot can be easily modified using additional parts from the 500 and 700 model Roombas. These modifications will allow the EZB(4) controller to be installed internally (out of sight) and allow more hardware to be installed within.

First the existing dust bin and vacuum/filter assembly can be removed and a 500 model "High Capacity" dust bin can be installed. The 500 model has no vacuum motor or filter assembly.

Second, the bottom plate can be removed and a 700 model bottom plate installed. What's nice about the 700 bottom plate is that the battery can be accessed by just removing two screws and lifting the battery access cover instead of the complete bottom plate.
