Self-propelled cleaner
First Claim
1. A self-propelled cleaner having a body with a cleaning mechanism with a rechargeable battery for cleaning with brushes, and a drive mechanism with replaceable drive wheel units at the left and right sides of the body which can be individually controlled for steering and driving the cleaner, comprising:
- a wireless LAN communication device which can transmit information to the outside and receive information from the outside through a wireless LAN;
a self-diagnosis processor which conducts self-checks including judgment about the condition of the rechargeable battery and judgment about the condition of the brushes based on the cumulative duration of use of the brushes and the cumulative distance traveled during their use; and
a consumables ordering control processor which, based on the results of self-diagnosis, checks the rechargeable battery for exhaustion and the brushes for wear, based on the cumulative duration of use of the brushes and the cumulative traveled distance, checks the drive wheels for abnormality and determines which consumables should be replaced, asks the user to decide whether to order or not and makes the wireless LAN communication device place an order.

Abstract
A conventional automatic ordering system requires stock management, so it is useless unless it is used on the assumption that stock is in hand and managed. In a self-propelled cleaner according to this invention, based on the results of a series of self-diagnosis steps (step S400 and subsequent steps) and the cumulative duration of use and the cumulative traveled distance as accumulated during daily cleaning operations (step 270), the necessity for an order for a replacement is judged (steps S431 and S427 to S478) and if ordering is necessary, the user is asked to decide whether to approve ordering (steps S482 and S484) and through a wireless LAN, an order is placed and payment is made by prepaid electronic money (steps S488 and S490). This automatic ordering system can be used conveniently in the home where consumable stock management is impossible.
