power limits

I think the 12 amp restriction applies to regular appliances, but I've seen the ratings on central vacuums at 14 or 15 amps, that's maximum, it doesn't mean it will pull that much power all the time. While I'm not a fan of governments telling manufacturers how they must make their products, 2000 watts is a bit extreme, that should not be required for good cleaning. I have an Electrolux 1205 here and I think the motor is around 500 watts, it cleans just fine. I also have a numatic Henry that has a 600 watt motor, again, no problems with cleaning power. It all comes down to good design. Unfortunately many people get caught up in the amp rating hype and they think that if it draws more power, it must clean better which is usually not the case. If anything, it's the opposite, this indicates that it's less efficient.

Just some notes about very high powered vacuums. My example was what you get when certain vacuum take the full advantage of the high powered motor.
Problem was that many of the manufacturers used bad quality motors and they just wasted the electricity.
One problem is that when the new EU law came manufacturers just put very low powered motors to vacuums that are designed to be used with higher powered motors. Result: poor performance.
I can't deny that having extremely powerful vacuum has its advantages. You don't have to "hunt" the dirt. Nozzle picks up more far away from the corners and so on. It makes cleaning faster and easier.
Some numbers: High powered vacuums had around 300-500 airwatts. Now with low powered vacuums it's 150-250 airwatts.
But for some reason many old twin fan vacuums has a great suction/airflow. For example my Lux Royal with 1150w (10amp) motor pulls over 7 on the baird airflow meter and suction is equally impressive.
So in this case no need for insane motor wattage.
I don't see myself buying these new limited power vacuums.
Instead I will get old good quality vacuum.
And let's not forget that all important powerhead.

The 5-7A 240V motors would be equivelant to 10A and 14A at 120V No advantage for the 240V motor in this case.

Dyson adapter

Where I work, we have a pretty good machine shop/electronics lab, and I made the Dyson tool adapter on a lathe. It's turned the vacuum into a versatility powerhouse, and it's the closest I'll get to having a central vacuum in an apartment. Love it, and use it often!

In the late 90's Regina had a housekeeper model that was 12.5 amps. It was unnecessary to have that much power.
