What motor size should you settle for?  Vacuum cleaner input power ratings have increased in a dramatic way since the 1960s from a normal 500W to more than 2500W these days. If that prompts your vacuuming to be five times faster you would be making use of the same amount of power.  If time isn’t a problem then maybe a less powerful model would do. Air watts happen to be an IEC60312 European test standard for vacuums. Learn more about airwatts by reading this article.

A cylinder vacuum cleaner has to be around 220 air watts and an upright vacuum cleaner should be about 100 air watts.  However, coupled with the need to reveal energy labels on vacuum cleaners, the regulations imply that makers won’t be able to import or make vacuum cleaners with motors that are more than 1,600 watts. There is debate as regards the sense of removing these bigger motors from the marketplace – certainly smaller wattage vacuum cleaners would take longer and make use of more energy? The challenge would be for makers to create machines that use the energy in the most efficient way.

Alongside the ever improving list of vacuum cleaners great for pet hair, allergy sufferers or hard floors you may notice makers speaking glowingly about the eco-vacuum cleaner being part of their range; models with low wattage with a claim of similar sucking power as what’s obtainable with a higher wattage motor.

However, upright vacuum cleaners generally appear to have greater energy efficiency than what’s obtainable with cylinder models, this is due to the fact that the extra pipes and tubes cylinder vacuums use need more energy for suction.  When you factor in the possibility for leaky seals in the pipes, it prompts an upright to be a very good eco choice. Then there are efficiencies of technologies employed, like microprocessor control and centrifugal fan systems; good nozzle and improved pipe design, all have a positive effect.
