Fill the water tank with clean water and secure the cap. Plug in the cleaner, turn it on, and wait for it to heat up. Attach the right nozzle for your task, then press the trigger to release steam. Move slowly over surfaces, letting the steam do the work. For tough stains, hold the steam over the area for a few seconds before wiping. If the water runs out, turn off the machine, let it cool, and refill. When finished, unplug, empty any leftover water, and store it.
