This steam cleaner does not use any electrical power.
The characteristic of electricity expressed in watts is power, which represents the rate at which electrical energy is consumed or produced. It measures how much energy is used or generated per unit of time.
A lamp doesn't produce electrical energy; it utilises it. The power-rating of the lamp will tell you the rate at which that lamp uses expends energy at its rated voltage. For example, a 60-W lamp will expend energy at 60 joules per second.
Your brain uses as much power as a ten watt battery. -Helen Brosnan
Kilowatts are a measure of electrical power. Kilowatt hours are a measure of how much electrical power has been used.

An electrical wire will heat up, depending on how much current passes through it. The amount of heat produced (and power wasted) is proportional to the square of the current. Usually, the main worry is that the circuit may overheat. Thus, it doesn't really matter how many machines or appliances you connect, but rather, how much total power they use.
