Input power (W)

The power consumption of a vacuum cleaner, in watts, is often the only figure stated. Many North American vacuum manufacturers give the current only in amperes (e.g. "6 amps"), and the consumer is left to multiply that by the line voltage of 120 volts to get the approximate power ratings in watts. The rated input power does not indicate the effectiveness of the cleaner, only how much electricity it consumes.

After August 2014, due to EU rules, manufacture of vacuum cleaners with a power consumption greater than 1600 watts were banned within the EU, and from 2017 no vacuum cleaner with a wattage greater than 900 watts was permitted.
