Abstract: A method for connecting a household appliance to a wireless home network, wherein a user terminal connects to a temporary communication network of the household appliance and transmits network access information for the home network to the household appliance, wherein the temporary communication network is ended subsequently and the household appliance logs into the wireless home network by using the received network access information, and wherein the user terminal obtains information from the household appliance about the fact that the log-in of the household appliance into the home network has failed. The household appliance opens a temporary communication network again if the log-in fails, wherein the user terminal recognizes the renewed opening of the temporary communication network and classifies it as information about the failure of the household appliance to log into the home network.

Abstract: An autonomous floor cleaning robot includes a body, a controller supported by the body, a drive supporting the body to maneuver the robot across a floor surface in response to commands from the controller, and a pad holder attached to an underside of the body to hold a removable cleaning pad during operation of the robot. The pad includes a mounting plate and a mounting surface. The mounting plate is attached to the mounting surface. The robot includes a pad sensor to sense a feature on the pad and to generate a signal based on the feature, which is defined in part by a cutout on the card backing. The mounting plate enables the pad sensor to detect the feature. The controller is responsive to the signal to perform operations including selecting a cleaning mode based on the signal, and controlling the robot according to a selected cleaning mode.
