No more corded vacuums to be developed by Dyson

[mike811]

Back to the subject.

If someone is wondering how powerful V10 really is. It has 52 cfm from the vacuum base and 25 cfm from the nozzle.
Typical corded Dyson upright has around 50-55 nozzle cfm.

I thought it was 52 in max and 25 in standard? If that is correct 52cfm in max is very good for a cordless.

 

[mike811]

It's the most powerful cordless stick type vacuum, but there is a difference compared to the mains powered vacuums

V10 on max
from the vacuum 52 cfm
from the nozzle 25 cfm

DC65
from the hose 76 cfm
from the nozzle 54 cfm

Sebo Felix
from the hose 100 cfm
from the nozzle 74 cfm

From Blue Ridge Cabin Cleaning YouTube Channel

And his preliminary measurements using a 1" diameter anemometer:

Dyson V10 (From Cyclone Base)
9447 Ft/Min = 107.9 MPH => 51.5 CFM (High Power)
4544 Ft/Min = 51.9 MPH => 24.8 CFM (Low Power)

Shark Ion Power (From Cyclone Base)
7547 Ft/Min = 86.2 MPH => 41.2 CFM (High Power)
5350 Ft/Min = 61.1 MPH => 29.2 CFM (Low Power)

Dyson V10 (From Nozzle)
4562 Ft/Min = 52.1 MPH => 24.9 CFM (High Power)
1935 Ft/Min = 22.1 MPH => 10.6 CFM (Low Power)

Shark Ion Power (From Nozzle)
3152 Ft/Min = 36.0 MPH => 17.2 CFM (High Power)
2198 Ft/Min = 25.1 MPH => 12.0 CFM (Low Power)

So, The V10 has 25 nozzle CFM on HIGH and 11 nozzle CFM on LOW. Now before you start jumping all over his measurements (that I have converted), he did say they weren't going to be super accurate. But, even if he was off by 10%, 20% or even 30% (which is doubtful), just think about how much money you're paying for staggeringly low nozzle CFM.

I'm not jumping over anyone haha


If that's wat it is that's what it is.

I still find it very good for quick pick ups I don't use it as my main vac.

I paid £250 for my V8

I said if someone proves me wrong I will take my hat off to them.
So here it is

Wow Mike! Thanks for the numbers.. I always assumed my Dyson DC65 and my newest Dyson Ball Animal 2 were more powerful (Suction wise) than my Felix.

I love my Sebo Felix even more now! I do have a soft spot for my German made vacuums and my Tacony USA made vacuums too of course. But I just love using my Sebo Felix for day to day cleaning.

It’s funny but does anyone else on here do what I do... clean out my bagless vacuum dirt bins (After the bulk is dumped in the trash) with my corded, bagged Sebo Felix attachments? The triangular soft brush does a great job! I’ve also been known to use my Swiffer Duster to get the dirt bins dust free and clean! Am I alone in this or will anyone else admit to keeping Bagless vacuums spotless clean after each use?? Oh my favorite trick, Roger (ibaisaic) taught me to use pop up cleaning wipes too.. they disinfect and leave a clean smell too.

I know... I’m crazy!

 

[vacfan1982]

One thing that wasn't mentioned is the V10 has a medium speed which most people will use as standard.. This setting will have more power than the Shark in the low setting.

I am a bit surprised by these results as Dyson claimed 151 air watts in Max mode, the Light Ball has 90 air watts.

 

[mike811]

Felix is very clever little vacuum. I love mine
It doesn't have same amount of suction what big Dysons have, but more importantly it has more airflow. Best cleaning clean air upright what I have.
Felix is not anything new. It's designed over 15 years ago. But why change a good design.
Highlight of the Felix is the ET-1 powerhead. Best powerhead what I have used and it also fits to my K-series canister

Those air watts should be thrown away. It's pretty useless measure. Light Ball has most likely a lot more airflow so comparing just the air watts is a bit misleading.
For example my Miele C3 has around 380 airwatts and my Philips Performer Pro 500 AW. Still both have the same level of airflow (108 cfm). Philips just have a lot more suction. In this case 144 inches of waterlift and Miele 90 inches of waterlift.

 

[vacfan1982]

I thought the Felix had 93 cfm at the hose Mike?

If you look at the loss from end of the hose to at the cleaner head how come the Felix and the DC 65 have a much lower percentage loss than the V10?

The V10 according to these test is losing 50% from end of hose to cleaner head and the Felix is losing just over 20% and the DC65 even less % loss.

This doesn't seem correct to me.

 

[vacfan1982]

I agree Airwatts is very misleading.

I also agree the Sebo Felix is an excellent bagged cleaner.

 

[mike811]

US Sebo Felix has 100 cfm measured by the blackheart. I measured 93 cfm from the 700 watt EU model

 

[vacfan1982]

Oh I see the US model has a has 1300 w so it would have slightly more CFM

That's very good airflow for a clean air vacuum. Well done Sebo!

 

[suckolux]

Remember it's only 120 volts here

 

[vacfan1982]

That is true but its the Voltage x Amps that gives the power in Watts

So for instance A 1000w in the UK using 240v would be just over 4 amps

In the USA a 1000w using 120v would be just over 8 amps but they are still both using the same power.

 

[suckolux]

Yes, it just limits our total power.

 

[vacfan1982]

Yes thats true.

Here in the UK the EU have limited our power to 900w and in some vacuums you can feel the drop in performance.

Although Numatic have somehow improved the performance of the Henry even though it went down from 1200w to 620w. I'm amazed at how they did that!

I think it's witchcraft

 

[suckolux]

So that would put your max power to around ours

 

[vacfan1982]

What is the max amps in the US? Is it 20 amps? That would make it about 2400w if my maths is correct
