A driving mechanism for an autonomous planar surface cleaning robot is disclosed. The driving mechanism includes a first transmission component and a second transmission component spaced apart in parallel relationship relative to the first transmission component. Each of the first and second transmission components defines first and second ends and first and second sides, wherein the first sides face each other and the second sides face away from each other in a direction transverse from the direction of motion and the first and second ends are oppositely spaced along the direction of motion. Each of the first and second transmission components are independently controllable by a control unit of the autonomous planar surface cleaning robot.

The present invention discloses a high flow low pressure suction device. The device is a non-contact suction device based on multiple stage turbulence based low pressure suction mechanism which comprises fan(s) or rotating impeller(s) for drawing air/fluid/slurries operates without any seal between the device and the sucked surface. The device compounds this turbulence based low pressure generation along with Bernoulli's principle to yield a high efficiency suction device. The device implements the above concept by making the air/fluid/slurries flow through two or three zones selected from the acceleration zone(s), turbulence zone(s) (high turbulence zone) and smooth zone(s) (minimum turbulence zone). The device works by pulling the air/fluid/slurries into the vacuum chamber, accelerating the air/fluid/slurries, creating turbulence in the air/fluid/slurries in a thin region near the perimeter in order to cause a drop in pressure and then maintaining pressure over a large bottom area and finally exhausting the air/fluid/slurries through the fan(s)/rotating impeller(s).
