i personally think motor wattage has gone way too high on vacuum cleaners as it does always mean higher motor wattage better pickup which is what the consumer mainly thinks! It's down to airflow and agitation is it not which equal air watts!? Out of interest where what is the amps of both motors in the Riccar Tandem airflow machines? DC18 No it doesn't. The aspects of higher power is used as a selling point to buyers - buyers aren't always interested in how much power a vacuum cleaner has - Dyson after all has bucked the trend for high wattage fitting 1200 watt and 1300 watt motors. Suction/power isn't just down to the air flow and agitation, but sealed suction so that no suction escapes. In the 1970s, cylinder vacuums didn't have a lot of power but as soon as they were given higher powered motors to improve suction power, this was also used as a selling point. However INHO cylinders/canisters and uprights are two very different vacuums. Riccar Brilliance (as featured in the video) has 2.12 amps. The Radiance model also have this rating. Now, if you need to convert this to watts, you'll need the voltage. Then convert it at: http://www.jobsite-generators.com/power_calculators.html

It was interesting to see both youtube videos, Riccar look impressive! Did anyone read the comments as well on there they were interesting to read too! One thing to look out for and will be interesting over the coming years is European Union want to bring in the Energy Label system to Vacuum Cleaners to show there ratings on similar areas to the Energy label System on other white goods (washing machines, fridges, dishwashers etc....). They also want to bring in max wattage (amps in the USA?) to vacuum cleaners for Uprights and Canisters, as it's been mentioned that the wattage of motors since the 1960 typical 500 watts has increased to over 2000 watts today. So it will be interesting to see where vacuum cleaner technology and design will go if and when this comes in.

Hello DC18:
Dual motors combine for a full 12 amps of power. That's probably the most amps for full size USA vacuums, including those rated for commercial grade. Which if translated to wattage would be the equivalent of 1200-1300 max. Carmine D.

The SEBO X4 has 10.8 amps but 1300 watt UK power. 12 amps doesn't equate to 1200 - 1300 but rather 1400 watts or more.

Hi Vacmanuk: The variable is the difference in currents between the USA and UK. 110 vice 220. Wattage on UK vacuums substantially exceeds USA. Appliances listed with wattage greater than 1500 are more than likely wired separately in the USA for 220 volts, like washer, driers, heaters, etc.
Carmine D. Here's the physics law: The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts
For example 1 amp * 110 volts = 110 watts This is a list of USA appliances designed for 120 volts. Typical Wattages of Various AppliancesHere are most examples of the range of nameplate wattages for various household appliances: - Aquarium = 501210 Watts
- Clock radio = 10
- Coffee maker = 9001200
- Clothes washer = 350500
- Clothes dryer = 18005000
- Dishwasher = 12002400 (using the drying feature greatly increases energy consumption)
- Dehumidifier = 785
- Electric blanket- Single/Double = 60 / 100
- Fans
- Ceiling = 65175
- Window = 55250
- Furnace = 750
- Whole house = 240750
- Hair dryer = 12001875
- Heater (portable) = 7501500
- Clothes iron = 10001800
- Microwave oven = 7501100
- Personal computer
- CPU - awake / asleep = 120 / 30 or less
- Monitor - awake / asleep = 150 / 30 or less
- Laptop = 50
- Radio (stereo) = 70400
- Refrigerator (frost-free, 16 cubic feet) = 725
- Televisions (color)
- 19" = 65110
- 27" = 113
- 36" = 133
- 53"-61" Projection = 170
- Flat screen = 120
- Toaster = 8001400
- Toaster oven = 1225
- VCR/DVD = 1721 / 2025
- Vacuum cleaner = 10001440
- Water heater (40 gallon) = 45005500
- Water pump (deep well) = 2501100
- Water bed (with heater, no cover) = 120380

DC18 and all:
Here's an interesting recent article with topics related oft talked about here but for washers in the USA. Enjoy. Whenever the gov't gets involved [read Congress] watch out. Carmine's law: Whatever objective the law tries to achieve, just the opposite results. http://online.wsj.com/article/SB10001424052748704662604576202212717670514.html Carmine D.

Interesting thread. I figured Dyson to be a dirty dog over six years ago, from day one. From perfecting the Dyson dump-shake-and-run technique to the wiping of the fine dust left along the bottom rim of the canister to the pressure washing of the cyclone unit against the advice of the manual, us longtime owners must surely be aware of its shortcomings by now. Three units later, I can safely say that I will likely never purchase a Dyson again. Chalk up my previous Dyson buys to ignorance. Back then if someone had mentioned Miele, Lindhaus, or SEBO, I would have scoffed. Who? What? No thanks. The most expensive brand of vacuum at the local department store is Dyson. Thus and therefore, Dyson must be the best. And I want the best. Kirby? That is for old-timers like my parents. I am young and I want something shiny and new. Dyson, or bust. Never thought to visit an independent dealer to expand my horizons. Thank goodness for the advent of online forums, review sites and shopping options, less I continue to be caught in the Dyson marketing loop forever.
