Huge airflow differences in the recent vacuums |

So I have been testing my vacuum cleaners airflow performance since I got my airflow meter.
Turns out to be, that differences are very dramatic. Most commonly the bagged vacuums have much more airflow than the bagless vacuums. I had to find out why. Turns out that the cyclone system eats huge amount of airflow. You can see it when I test the Dyson DC40 cyclone system in the video. This is almost upsetting, because the Dyson cyclones work extremely well. Also Shark has low airflow, but not low as the Dyson and the motor is smaller. Miele C3 has huge airflow and the Sebo Felix with the EU 700w motor is also good. I just wanted to share some of my thoughts. | ||

Miele C3 should have 1200 watt motor
Sticker in the bottom says 1600 watts, but the guy who sold it to me said that he swapped the motor. Now it should be 1200 watts according what he said. I guess it's possible to pull 10. For some reason now it pulls 9.
Dyson DC40 (1100 watts) had a hard time pulling just a 1. Straight from the motor without the cyclones it pulls 8. Old school Lux Royal D790 (1150w, longer 8.2ft hose) from the mid 90īs pulls 7,5 and with the Dyson cyclones it pulls 2. Not very efficient motor in the Dyson obviously. My mid 90's Nilfisk GM80 with the 1100 watt motor and extra long 8.2ft hose pulls almost 9. Here is all of my airflow and suction measurements: | ||

Mike, Way back in June of 2017
I sent you a link for an inexpensive EU type power meter.
http://www.ebay.com/itm/US-UK-EU-AU-Plug... I've seen manufacturer's ratings be hilariously off. Bill | ||

We also have 15A 1800W motors-my Tornado "Task Forece" W/D vacuum has such a motor.My new VitaMix "Quiet One" blender has a 15A 1800W motor! | ||

I have one of the Baird meters, the only canisters that will pull the indicator all the way back are the Apex Strato Cleaner, Westinghouse from 1959 and the Sunbeam Dual Deluxe....all are SINGLE FAN MOTORS! | ||

So the Miele is gonna clean better than all of them? Interesting. | ||

All else being equal, yes - but all else rarely is equal. That said, Mieles have good power nozzles, so they do clean very well. Are they on par with Kirby or Royal for carpets? Probably not, but then, not much is. (Being a canister, the Miele is extremely versatile, of course.) | ||

Airflow difference in real life
So what the airflow means in the practice?
For me it's the ability to vacuum faster, vacuum picks up more far away from the nozzle, deeper clean carpets and overall making vacuuming more pleasant experience. No need to try place the nozzle very near the dirt. This is my personal experience. About the Miele C3 motor. It well might be very high wattage. Most powerful motors what we had in the EU were 2200 watts. I should get the power meter so I can find out. Here is one video comparing the 100 cfm Lux Royal D790 vs 55 cfm Dyson DC40. Airflow difference is clearly visible. | ||

The Sharks do have decent agitation, which covers a lot of ills. But then, so do Royals. When I looked, the only metal Royals listed were rated Gold. I'd bet the shake-out bag versions got silver for filtration (which the Sharks do OK on, while the filters last). | ||

The more airflow the better in general, but if you can shake the dirt to the surface, whatever airflow you have will get more of it - this is why good agitation "covers" poor airflow to a point. (To a point - nothing beats airflow for moving fine dust). | ||

Shark cleaning well?
I am not huge Shark fan, but I have to say that they clean well for what they are. For example my Shark NV500 did the flour under the carpet test surprisingly well. Now why if the airflow is bad? Small nozzle has good airflow density (cfm per square inch). Also the brushroll is agressive greating a good agitation. In certain carpets the brushroll pulls the vacuum forward.
Here is one video of the Kirby G6 vs Nilfisk GM80 vs Shark NV500. Nilfisk airflow 106 cfm and Shark 65 cfm from the hose end. Kirby is WAY over 100 cfm. | ||
