Benefits of technology

[0009]Presently disclosed is an autonomous robot for treating surfaces, such as floors and countertops, which has a form factor that facilitates cleaning in tightly dimensioned spaces, such as those found in many households. In one example, the robot may include a weight distribution that remains substantially constant throughout the cleaning process, the weight distributed between a

Problems solved by technology

The cleaning fluid interacts with contaminants on the surface and may dissolve or otherwise emulsify contaminants into the cleaning fluid.
The rinsing step contaminates the cleaning fluid with waste liquid and the cleaning fluid becomes more contaminated each time the mop or sponge is rinsed.
As a result, the effectiveness of the cleaning fluid deteriorates as more of th

Embodiment Construction

[0071]An autonomous robot may be designed to clean flooring. For example, the autonomous robot may vacuum carpeted or hard-surfaces and wash floors via liquid-assisted washing and / or wiping and / or electrostatic wiping of tile, vinyl or other such surfaces. U.S. application Ser. No. 11 / 359,961 by Ziegler et al. entitled AUTONOMOUS SURFACE CLEANING ROBOT FOR WET AND DRY CLEANING, the disclosure of which is herein incorporated by reference in its entirety, discloses an autonomous cleaning robot.

[0072]An autonomous robot is movably supported on a surface and is used to clean the surface while traversing the surface. The robot can wet clean the surface by applying a cleaning liquid to the surface, spreading (e.g., smearing, scrubbing) the cleaning liquid on the surface, and collecting the waste (e.g., substantially all of the cleaning liquid and debris mixed therein) from the surface. As compared to comparable-sized autonomous dry cleaning robots, an autonomous wet cleaning robot can rem...

Abstract

An autonomous coverage robot detection system includes an emitter configured to emit a directed beam, a detector configured to detect the directed beam and a controller configured to direct the robot in response to a signal detected by the detector. In some examples, the detection system detects a stasis condition of the robot. In some examples, the detection system detects a wall and can follow the wall in response to the detected signal.

Description

CLAIM OF PRIORITY[0001]This U.S. patent application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application 60 / 938,699, filed on May 17, 2007 and U.S. Provisional Application 60 / 917,065, filed on May 9, 2007. The disclosures of the prior applications are considered part of the disclosure of this application and are hereby incorporated by reference in their entireties.[0002]The contents of U.S. Pre-grant Publications 2008 / 00652565, 2007 / 0244610, and 2007 / 0016328, 2006 / 0200281, and 2003 / 0192144, and also U.S. Pat. Nos. 6,748,297 and 6,883,201 are hereby incorporated herein by reference in their entireties.TECHNICAL FIELD[0003]The disclosure relates to surface cleaning robots, such as robots configured to perform autonomous cleaning tasks.BACKGROUND[0004]Wet cleaning of household surfaces has long been done manually using a wet mop or sponge. The mop or sponge is dipped into a container filled with a cleaning fluid to allow the mop or sponge to absorb an amount of the c...
