1. A rotating cleaning element configured to be inserted in a cleaning head compartment of a robotic vacuum, the rotating cleaning element comprising:
- a drive end comprising a drive protrusion configured to engage a drive mechanism of the cleaning head compartment and a retention device configured to limit axial motion of the cleaning element, the retention device including interlocking members configured to engage one or more recess in a drive gear that engages the drive protrusion;
a bearing end and a shroud configured to surround at least a portion of the bearing end to lessen an amount of hair and similar matter that reaches the bearing, wherein the shroud comprises;
a first wall disposed generally parallel to a central axis of a central member;
a second wall extending generally perpendicular from the first wall;
a third wall extending generally perpendicular from the second wall; and
a fourth wall extending generally perpendicular from the third wall, the first, second, third and fourth wall defining the interior of the shroud; and
the central member extending between the bearing end and the drive end;
wherein each interlocking member has a proximal end attached to the central member and extends to an unattached distal end defining a retention feature configured to releasably engage a recess defined by the drive end of the cleaning element.

13. A cleaning head subsystem for a robotic vacuum, the cleaning head subsystem including a cleaning head compartment and at least one cleaning element, the cleaning element comprising:
-
a bearing end and a first shroud configured to surround at least a portion of the bearing end and a sleeve thereof; a first reservoir being defined at least between a portion of the first shroud and the sleeve; a drive end comprising a drive protrusion configured to engage a drive mechanism of the cleaning head compartment and a retention device configured to limit axial motion of the cleaning element, the retention device including interlocking members configured to engage one or more recess in a drive gear that engages the drive protrusion; and a central member extending between the bearing end and the drive end; wherein the drive end includes a second shroud configured to surround at least a portion of the drive end and at least one guard extending radially outwardly from a central axis of the central member toward an interior of the second shroud, a second reservoir being defined at least between a portion of the second shroud and the guard; and wherein each interlocking member has a proximal end attached to the central member and extends to an unattached distal end defining a retention feature configured to releasably engage a recess defined by the drive end of the cleaning element.
