Front Castor with rubber

Rubber Roomba 5/6/78 or 900 front castor assembly for very sensitive floors.
Some highly polished floors or floors with a soft top layer can get scratches very easily with the standard iRobot front castor. This wheel has a rubber ring which will not scratch your floor.

Also included in this special castor design is an axle with bearings, the wheel will not get stuck so easy now.
