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;
- 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;
- and
- a central member extending between the bearing end and the drive end.
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 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 of the brush assembly 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.
A cleaning head subsystem for a robotic vacuum, the cleaning head subsystem comprising:
- a cleaning head compartment;
- a cleaning element assembly disposed within the cleaning head compartment, the cleaning element assembly including a main brush and a flapper brush;
- and
- a gearbox comprising a main brush drive gear to drive the main brush, a flapper brush drive gear to drive the flapper brush, and a first shroud configured to surround at least one of the main brush drive gear and the flapper brush drive gear.
