Great Video Mike, But I Have A Question You have two pictures of your Nilfisk pulling a "Baird" 10, which is 110 CFM. BUT, in one pic, you have stated 123 CFM and another 115 CFM. Did you purchase some other anemometer to measure past 110 CFM? Anyway, here's the Baird CFM chart again for...

Mike, That webpage is correct. Your suction gauge goes to 2500mm H2O, which is about 100 inches of water, which is about 25 kPa. What will you need the kPa conversion for by the way? Bill

Baird Meter Conversion Table Although I've posted this many times before, here it is again. From Baird "0" to Baird "8", the spring in the meter itself is fairly linear and amazingly accurate. The last two markings, namely "9" and "10", are non-linear as the spring becomes stretched beyond its...

Miele C3 Cat & Dog Devin, When you first gave me the measurements of the C3, you had measured 101 CFM at the end of the hose and 95 CFM at the end of the extended wand (just before going into the power nozzle). Do you have any idea as to why your newer measurements are so much lower? The end...

GM8901 Conversion Factor This is how you convert feet per minute into CFM when using this anemometer. Diameter of GM8901 Anemometer Detector = 2.1875 inches Radius = 1.09375 inches = .0911458 feet Detector Area = 3.1415926 x .0911458 x .0911458 = 0.0260990 (rounded) Sooooo, if the vacuum...

Harley, I've done three. Here's the video: Bill

Jakob, Airflow Box Introduction Airflow Box Test of the Kirby Sentria II GM8901 Anemometer ($25.21, Free Shipping) http://www.ebay.com/itm/GM8901-Anemometer-Wind-Speed-Gauge-Temperature-Measure-Digital-thermometer-ZQ-/302359399502 Baird Meter...

Another Airflow Shocker... I'm stunned that such an expensive machine still has no better nozzle airflow than a typical bag-less cheapie. I love the look and features of the S7, but your tests reveal that Miele has produced an expensive package that's nothing more than a look and features...

You have to make your own airflow/airwatts box And then grab yourself an anemometer. Check out my YouTube channel VacLab for how to videos. Bill

Almost 59 CFM, That's Towards The Top Of the heap for a bagless machine. So you also were able to get suction measurements at the power nozzle, eh? Very cool! I'll have to build another air box that can do more than just measure airflow. Bill

Excellent work again Devin! But am I seeing your nozzle CFM correctly? With both motors on, there is only a 2.57 CFM increase? If that's true, wouldn't that be proof of a poor design? Bill

So for several thousand dollars new, the Rainbow E2 gives you about the same performance (nozzle CFM and water lift) as a typical Chinese made inexpensive bag-less vacuum. Shocking! That being said it still is a very cool machine (I want one) and I'm very happy that the PN does about 21 CFM...

Here Are 14 "Agitation" Measurements So Far... Or however you'd like to classify them. All the corresponding videos are on my VacLab channel of course. Jakob, The bristles on the brush roll can provide the agitation without having beater bars. Take the Kirby stiff bristled oblique brush roll...

Oh, I'm lovin' these tests! Keep going! What's next? Rainbow E2? A 10 Amp Royal? Lux Guardian Platinum? Miele something-or-other? Whoohoo! Great work! Bill

85 CFM from the XL21 must mean That it has a larger fan? I'll keep an eye out for one of these at the thrift stores. And please keep those tests coming, especially for machines I've never tested yet. Great job! Bill
