AN AUTONOMOUS MOBILE ROBOT FOR CLEANING WITH A FRONT ROLLER IN A FIRST HORIZONTAL PLANE POSITIONED ABOVE A SECOND HORIZONTAL PLANE OF A REAR ROLLER

WIPO Patent Application WO/2012/149575

A8

An autonomous mobile robot comprise: a chassis having a drive system mounted therein in communication with a control system; a cleaning head assembly having a lower cage and mounted to the chassis; a debris collection bin mounted to the chassis; a vacuum airway having a vacuum inlet and an airway outlet positioned adjacent the debris collection bin, and configured to deliver debris from the cleaning head assembly to a debris collection bin, the vacuum airway extending between the cleaning assembly and debris collection bin and being in fluid communication with an impeller disposed within the debris collection bin; and a cleaning head module connected to the chassis and having a front roller including a front shape-changing resilient tube and an adjacent rear roller including a rear shape-changing resilient tube rotatably opposing therewith beneath the vacuum inlet. The surface of the front shape-changing tube and the surface rear shape-changing tube are separated by a narrowest air gap of less than 1 cm, such that the vacuum draw directed from the vacuum airway is concentrated within the narrowest air gap.
