Autonomous surface cleaning robot for dry cleaning

摘要

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

主权项

1. An autonomous cleaning robot comprising:
a chassis of the autonomous cleaning robot having a lower surface defining at least a portion of a channel open toward a cleaning surface; a drive system carried by the chassis and configured to maneuver the robot over the cleaning surface, the drive system comprising right and left driven wheels defining a transverse axis and configured to move the robot along a fore-aft axis substantially perpendicular to the transverse axis; a waste storage container carried by the chassis; and an air moving system carried by the chassis, the air moving system configured to generate a negative pressure and a positive pressure, and the air moving system comprises conduits configured to apply the positive pressure at a first portion of the channel and configured to apply the negative pressure at a second portion of the channel, the second portion of the channel in fluid communication with the waste storage container, wherein the first portion of the channel defines an air jet port lateral to the fore-aft axis, the second portion of the channel defines an air intake port aft of the air jet port, and the air jet port directs air along the channel in a lateral direction toward the air intake port.
