1. A surface cleaning apparatus comprising:
- a base, a lid and a gap formed between the base and the lid;
an electrolyzing device comprising first and second power supply terminals, a reaction chamber having an anode and a cathode coupled to the first and second power supply terminals, and a liquid flow path through the reaction chamber from an inlet to an outlet of the electrolyzing device;
an indicator light, which is controlled as a function of an electrolysis of liquid by the electrolyzing device, wherein the indicator light is positioned within an interior of the apparatus, near the gap, and light from the indicator light is visible through the gap from an exterior of the apparatus; and
an indicator control circuit, which operates the indicator light as a function of a level of current drawn by the electrolyzing device.

Abstract
A surface cleaning apparatus is provided. The apparatus includes a mobile body configured to travel over a surface, a cleaning device carried by the mobile body, a liquid flow path, and an electrolyzing device in the liquid flow path. An indicator provides a humanly-perceptible indication of an electrical operating characteristic of the electrolyzing device.

11. A method comprising:
-
a) onboard a surface cleaning apparatus, electrolyzing a liquid at least by a process of electrolysis with an electrolyzing device comprising first and second power supply terminals, a reaction chamber having an anode and a cathode coupled to the first and second power supply terminals, and a liquid flow path through the reaction chamber from an inlet to an outlet of the electrolyzing device, wherein the surface cleaning apparatus comprises a base, a lid and a gap formed between the base and the lid; b) onboard the surface cleaning device, measuring an electrical characteristic of the electrolysis process that is representative of a level of current drawn by the electrolyzing device; and c) illuminating an indicator light as a function of the electrolysis process and the level of current drawn by the electrolyzing device to produce a humanly-perceptible indication of the electrical characteristic wherein the indicator light is positioned within an interior of the apparatus, near the gap, and light from the indicator light is visible through the gap from an exterior of the apparatus.
