Roomba i4 - Bumper Extender

This is a vertical bumper extender for the Roomba i4 vacuum cleaner. Because of the curved top edge of the i4 bumper, traditional bumper extenders do not mount nicely to the radiused edge. This bumper extender has a lip that sits between the bumper and the main body (see pictures), while still allowing the bumper to press inwards when it hits an obstruction. It attaches nicely with hot glue.

This bumper extender extends the height by 0.5 inches vertically, and does not protrude any further outwards than the actual bumper. This bumper extender still allows for the i4 to maneuver under the standard cabinet toe-kick height of approximately 4 inches.

Print one for each side of the bumper.
