Direct air power nozzle

Well, if anyone has a cheap Baird meter they want to sell me, I now have a C3 an Avalir and U1. Oh, and a Moxie too.

Marcus - Now you get what I was saying in my thread about UK prices vs US prices. In the case of Miele they tend to be about twice what you pay. In the case of Sebo anywhere from 3-4 times what you pay in the UK.

Miele C3

The shop i work at is a miele dealer! I took these readings off a Miele C3 cat and dog. We placed the vacuum on the ground, held the hose as straight as we could, took the ratings, and this is what we got.

EXCELLENT WORK DEVIN!

A 7.5 is just about dead on 101 CFM from a straight hose. For your wand measurement, I'm assuming that you have the wands extended about three feet. A 6.5 is an equivalent to 95 CFM.

Based on typical airflow losses from wand connections and the power nozzle u-joint, a C3 may do around 85-90 CFM at the nozzle when placed on an airflow box.

Now, you wouldn't by chance have a suction gauge you could place on the end of that hose?

Thanks a bunch!

We do.

I'll get a suction reading Saturday I'm taking tommorow off.

Thank you for that Devin.

It's about what I was expecting. 101 CFM at end of the hose is still good for a bypass motor.Plus Miele 9 layer bags do not lose any noticeable airflow as it fills and Mieles filtration is fantastic.

Bill,


 


where did you het the key for the Baird meter? Did you create it with your digital anemometer?


 


Just curious.

Stan,

Yes, and here's how the testing procedure went.

Example:

1) obtain a vacuum source that creates, say an "8" on the Baird meter.
2) remove said Baird meter and attach my GM8901 digital anemometer and take reading.
3) repeat the above two steps at least three times to obtain reliable, repeatable results for all possible Baird readings (zero to 10).

These tests MUST be done very carefully, paying special attention to the airflow source (i.e. the hose end, that it does not move). The GM8901 can give a useful resolution to about 0.25 CFM.

Thanks for asking,

Bill

I wonder if someone on here will make a bag attachment for the Riccar Volt? Like, a pistol grip handle with a bag on it? Definitely would be interesting.
Sebo4me...
I doubt the Shark will ever match or beat Kirby. The Shark is crap. This post would be much longer if I went into everything I hate about it.

 

[sebo4me]

It won't match the Kirby but it's still very good value for money. Certainly not crap. I own the Powered lift away. I've found it to do a very good job. I also love the powered lift away feature allowing the the user to get under furniture etc.

Sharks customer service in the UK is excellent. I can see why it's become the USA's biggest selling vac

Thanks Bill for taking the time to do all those measurements and for taking the time to explain the process.

price of Miele and Sebo

Sounds like there is definitely a price difference between what the Miele and Sebos cost in Europe compared to the United States. I wonder if it's because of import costs, or perhaps they don't sell as many models that use 120 volts so they need to charge more for them. On the other hand, the Numatic Henry is quite a bit cheaper and those are made in the U.K. I can't help but wonder how much those vacuums are taxed when they are imported, and if that's what causes the price to increase so much. Miele and Sebo definitely make good products, but they do cost a premium here.
