Abstract: A cleaning roller mountable to a cleaning robot includes an elongate shaft extending from a first end portion to a second end portion along an axis of rotation. The first and second end portions are mountable to the cleaning robot for rotating about the axis of rotation. The cleaning roller further includes a core affixed around the shaft and having outer end portions positioned along the elongate shaft and proximate the first and second end portions. The core tapers from proximate the first end portion of the shaft toward a center of the shaft. The cleaning roller further includes a sheath affixed to the core and extending beyond the outer end portions of the core. The sheath includes a first half and a second half each tapering toward the center of the shaft.

Abstract: A rotating cleaning element configured to be inserted in a cleaning head compartment of a robotic vacuum, the rotating cleaning element including: a drive end including 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.

Abstract: A cleaning roller is mountable to a cleaning robot. The cleaning roller includes a sheath comprising a shell, an outer diameter of the shell tapering from a first end portion of the sheath and a second end portion of the sheath toward a center of the roller. The cleaning roller further includes a core including a central portion interlocked with the sheath to rotationally couple the core to the sheath and inhibit relative translation of the sheath and the core along an axis of rotation. An inner surface of the sheath and an outer surface of the core define an air gap therebetween, the air gap extending from the central portion of the core longitudinally along the axis of rotation toward the first end portion or the second end portion.

Abstract: A clinical diagnostic sample analyzer for analyzing a sample of a patient is disclosed. The analyzer includes a telescoping closed-tube sampling assembly with a sample probe concentrically housed within a piercing probe and a venting mechanism. The closed-tube sampling assembly is used for aspirating a sample from a sample tube for analysis by a clinical diagnostic sample analyzer.
