Autonomous surface cleaning robot for wet and dry cleaning
First Claim
1. A surface treatment robot, comprising:
- a robot body having an outer perimeter formed substantially as a shape of constant width, driven forward by at least one circulating member;
a dispensed material compartment that holds material to be dispensed by the robot;
a wet cleaning head that employs at least one wet cleaning member to clean along a cleaning width line of the robot with the assistance of dispensed material, the wet cleaning head defining a cleaning width; and
a waste material compartment that holds material picked up by the robot;
each of the dispensed material compartment and waste material compartment being shaped and positioned to place the center of gravity of the dispensed material compartment volume less than ½
of the cleaning width from the center of gravity of the waste material compartment volume.

Abstract
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.

7. A surface treatment robot, comprising:
-
a robot body having an outer perimeter formed substantially as a shape of constant width, driven forward by at least one rotating member;
a dispensed fluid compartment that holds fluid to be dispensed by the robot;
a powered wet cleaning head that employs at least one powered wet cleaning member to clean a cleaning width along a cleaning width line of the robot with the assistance of dispensed fluid; and
a waste material compartment that holds waste fluid picked up by the robot;
the wet cleaning head having a cleaning width with respect to total robot mass of the robot body, dispensed material compartment when empty, wet cleaning head, and waste material compartment when full of waste fluid picked up by the robot, of more than or equal to three centimeters of cleaning width per kilogram of total robot mass. - View Dependent Claims (8, 9)

10. A surface treatment robot, comprising:
-
a robot body having an outer perimeter formed substantially as a shape of constant width, driven forward by at least one rotating member;
a wet cleaning head that employs at least one circulating wet cleaning member to clean a cleaning width along a cleaning width line of the robot with the assistance of dispensed fluid;
a tank that accommodates a fluid compartment for storing fluid, the robot body including a mount that receives the tank;
a fluid connection between the tank and the robot body;
a vacuum connection between the tank and the robot body;
a coupling that mechanically engages the tank to the robot body, the engagement of the coupling simultaneously sealing both the fluid connection and the vacuum connection. - View Dependent Claims (11, 12)
