New EU Rules Will Limit Vacuum Cleaners To 1600W
AmiMoJo writes "New EU rules are limiting vacuum cleaner motors to 1600W from 2014/09/01. The EU summary of the new rules explains that consumers currently equate watts with cleaning power, which is not the case. Manufacturers will be required to put ratings on packaging, including energy efficiency, cleaning efficiency on hard and carpeted floors, and dust emissions from the exhaust. In the EU vacuum cleaners use more energy than the whole of Denmark, and produce more emissions than dishwashers and washing machines."
1600W is about two horse powers, and if you think you can keep a house clean with two horses running though it, I have a barn to sell you.
/me shows self to door
In the US our consumer-grade vacuum cleaners are already effectively capped around the same wattage. The standard household electrical outlet is rated to provide 15 amps and does so somewhere between 100 and 125 volts. That's 1500-1875 watts as the maximum any single device clet an expect to pull without requiring a special outlet. Nothing in reality expects the higher end of the spectrum because it's by no means guaranteed.
Somehow we get along just fine, residential or commercial, with pretty much the same as what this limit allows. /me awaits some Brit who's come to explain how their 240v 13A outlets allow them to suck the carpet right off the floor with their cleaners.
I used to get high on life, but I developed a tolerance. Now I need something stronger.
They can have my 2000watt vacuum cleaner when they pry my cold dead hands...
Try switching it off; you're lucky it's only got you by the hands.
My Roomba is using about 30 Watts for its vacuum and that is more than enough.
Fire hazards are not directly linked to wattage. It's all about overheating. Bigger power motors are bigger (surprise) and are capable of withstanding more heat because of it.
Additionally higher wattage does not mean more power use in an ordinary scenario. An induction motor will still only draw the amount of power needed to get it spinning to the correct speed. Take a 1400W vacuum and a 2400W vacuum and put them on the carpet they'll likely draw the same amount of power.
Now quite critically when you block the suction pipe that's when the differences become evident. Most vacuums have a relief valve which will allow it to suck air in after a certain pressure is reached. This RV will dictate the amount of power that the vacuum sucks and if sized correctly the motor will still not draw its full rated current. What will happen in reality is the higher rated motor will have a lower minimum suction pressure and a lower set RV.
Where the entire mess catches fire is either:
a) Stupidly set RVs
b) Lack of overload protection for the motor.
c) Stupid design of the vacuum that doesn't provide adequate cooling (I've had a hot air gun catch fire in my hand once due to such brain dead design, that tip will never get hot, lets support it with plastic. What could go wrong.)
This doesn't excuse the stupidity of selling a 2400W vacuum, but power does not directly equate to fire hazard.

"[Assuming efficiency improvements of 16% to 33%...] Estimated per-unit annual savings for residential vacuums are on the order of 10-19 kWh/year... Considering there are approximately 28 million vacuums sold in the U.S. each year, the national energy savings opportunity would be on the order of 67,000-135,000 MWh per year if 25% of products sold were replaced with energy efficient models"
Contrast that the the document linked in TFA: ... of vacuum cleaners
will be reduced by 19 TWh"
http://ec.europa.eu/smart-regu... says
"[Vaccuum cleaners sold per year in 2005 and 2020: 54 million and 92 million]... [Energy consumed by vacuum cleaners under business-as-usual by 2020: 29.7 TWH/year]... by 2020, the annual electricity consumption
So, 67 TWh annual savings in US vs. 19 TWh annual savings in EU in spite of twice as many vacuum cleaners sold per year in the EU. Is there just more dirt in the US? Or was the Energy Star scoping report just overoptimistic?
