Coverage robots and associated cleaning bins
First Claim
1. An autonomous cleaning robot comprising:
- a drive system configured to maneuver the autonomous cleaning robot about a floor surface;
at least one rotatable brush configured to agitate debris on the floor surface; and
a removable bin configured to receive the debris agitated by the at least one rotatable brush, the removable bin comprising;
a first portion having a first width extending along a first axis,a second portion having a second width extending along a second axis parallel to the first axis, the second width being longer than the first width of the first portion of the removable bin,a mouth extending along at least part of the first width of the first portion of the removable bin, anda plurality of teeth disposed substantially along the mouth of the removable bin, the plurality of teeth configured to strip debris from the at least one rotatable brush during rotation of the at least one rotatable brush, the debris stripped from the at least one rotatable brush and the debris agitated by the at least one rotatable brush being allowed to accumulate in the removable bin.

Abstract
An autonomous coverage robot includes a chassis, a drive system configured to maneuver the robot, and a cleaning assembly. The cleaning assembly includes a cleaning assembly housing and at least one driven sweeper brush. The robot includes a controller and a removable sweeper bin configured to receive debris agitated by the driven sweeper brush. The sweeper bin includes an emitter disposed on an interior surface of the bin and a receiver disposed remotely from the emitter on the interior surface of the bin and configured to receive an emitter signal. The emitter and the receiver are disposed such that a threshold level of accumulation of debris in the sweeper bin blocks the receiver from receiving emitter emissions. The robot includes a bin controller disposed in the sweeper bin and monitoring a detector signal and initiating a bin full routine upon determining a bin debris accumulation level requiring service.
