Abstract: A method of operating a mobile cleaning robot includes receiving a privacy mode setting from a user interface, where the privacy mode setting is based on a user selection between at least two different privacy mode settings for determining whether to operate the mobile cleaning robot in an image-capture-restricted mode. An image stream of an image capture device of the mobile cleaning robot is permitted in an absence of a user-selection of a more restrictive one of the privacy settings. At least a portion of the image stream is restricted or disabled based at least in part on a user-selection of a more restrictive one of the privacy settings.
