So after I got my baird airflow meter and testing different vacuums bagless/bagged. I discovered something interesting.
Bagless vacuums seems to have a poor airflow compared to bagged ones. Some examples: Bagged vacuums (clean air type) pulled around 5 to 9. Best: Philips Performer Pro (20amps 2200w) pulled 9. Bagless vacuums pulled around 2 to 4,5. Best: Electrolux UltraFlex (19amps 2100W) This is something what I have seen in numerous Youtube videos also. Also the best bagless vacuum Dyson usually have only 2 from the baird airflow meter. So question is: Is there really bagless vacuum that can pull at least 5 to 6?? Thanks |

Nice to hear that.
I have Shark Rotator Lift-Away Pro which cleans quite well (not good as the Kirby G6). I just have one carpet where it struggles to get it clean. Otherwise pretty good and it only pulls 2 on the airflow meter. Kirby pulls 10. Shark is just very easy and versatile to use.

Mikko,
You can see that from the base of the machine (BEFORE the cyclones) in the various bag less vacuums listed here, airflow is excellent. Baird tests reveal a 9-10 range. AFTER the cyclones, the airflow drops like a stone, typically down to a 3. The best airflow at the hose end I have is a DC14, which scores a 4 (about 77 CFM). BTW, when testing your machines, be sure to stretch the hose out straight and as level as possible. Twisting the hose up like a pretzel reduces airflow and thus your Baird reading will be lower.

Both a direct air and clean air vac work on the same principle.
The motor spins a fan which causes a drop in ambient pressure and causes air to flow. A direct air cleaner has the bag after the fan and pushes the dirt into the bag. A clean air machine has the bag before the fan and pulls the dirt into the bag. It's not rocket science is it 😁 Interesting results. So it's the cyclones that reduces the airflow. |
