1. A robot cleaner including:
- a cleaning unit;
wheels to move the robot cleaner; and
a processor to control the robot cleaner, wherein an estimate of room size is determined based on distances between obstacle detections, and the estimate of room size is used to determine the distance that the robot cleaner goes in a wall following mode when the robot cleaner attempts to move to a new area.

Abstract
The invention covers a robot cleaner that includes a cleaning unit and wheels to move the robot cleaner. The robot cleaner also includes a processor for controlling cleaning that is capable of estimating the size of a room based on distances between obstacles. The robot cleaner has several modes of operation that allow it to clean an entire room more effectively.

22. A robot cleaner including:
-
a bumper;
a cleaning unit; and
a processor to control the robot cleaner, wherein a first floor region next to a wall is cleaned with the robot cleaner such that the bumper of the robot cleaner contacts the wall, the robot cleaner backs up, and wherein a second floor region next to the wall is cleaned with the robot cleaner such that the bumper of the robot cleaner contacts the wall, the second floor region being adjacent to the first floor region.

23. A robot cleaner including:
-
a cleaning unit with a brush; and
a processor to control the robot cleaner, wherein an entanglement of the brush is detected, the brush is turned off, the robot cleaner moves forward with the brush off, and the brush is turned on to detect whether the entanglement is removed.

24. A robot cleaner system comprising:
-
a robot cleaner including a cleaning unit and a processor; and
a remote control including a directional control, wherein a directional command from the remote control causes the robot cleaner to shift the cleaning in one direction without requiring a user to hold down the directional control until a spot is reached. - View Dependent Claims (25, 26, 27)

28. A robot cleaner including:
-
a housing;
a cleaning unit at the bottom of the housing; and
a bumper on the housing to sense obstacles, wherein after contacting an obstacle with the bumper, the robot cleaner does a serpentine clean having segments that lengthen as the robot cleaner moves away from the object.
