I've got both a D4 and a Felix. Their airflows are similar at the power head. In regards to suction the Felix is stronger the D4 had about 70" at the hose vs the 76" of the felix. there's a leak around the bag indicator that causes that
Between the two machines I think I prefer the D4. Why? It's quieter, the non stretch hose makes above the floor cleaning easier, the bags are larger, the cord winder is a nice convenience. If you prefer a one piece machine though you may be better off with a Felix, but IMO you should get the Premium parquet tool 7200GS, remove the front strip, and use it with your D4. I'm more likely to use the felix's floor tool than the basic floor brush that came with the D4

@jp10558 The D4 has more power then the Felix. Working water lift is the proper way to test that ! Stop playing around with airflow olny tests .
As I replied to you "You're doing it wrong " . Try this with the floor tool.

I used a brand new Sebo D4 Premium at a Bed and Breakfast years back. I liked that it was quiet, had a long 40' cord, which is the longest on a canister vac that retracts. It also stored the crevice tool, dusting brush and upholstery nozzle on board which were all decent sized attachments too and not "Barbie's playhouse" style size like on some others on the market. Anyway, it was the performance of the vacuum that highly disappointed me. I found the ET-1 power head had poor agitation regardless of what height setting I tried and the suction/ air flow to be limiting. I always ran it at max power with the indicator light flashing around as fast as it would go, but I was never impressed by its performance on any surface unless with the dusting brush or upholstery nozzle. With the smaller attachments it did good but put on the power head or bare floor brush and it seemed lacking. About a year ago I tried another D4 on a display floor of a vacuum shop and it felt the same.
I love canister vacs but this one is not powerful enough. Get a Riccar/ Simplicity, or Miele, all of those have great power!!! |

This video shows very clearly how much airflow matters.
In this video I tested the 1600w Miele C3 with 120 cfm from the hose end and Dyson DC40 mkII with 66 cfm from the hose end. Suction in these is quite near each other. Difference in the pick up is huge. I personally like the Sebo ET-1 powerhead. It doesn't have much visual agitation, but it grooms the carpet extremely well. I use it with my Sebo Felix and Sebo Airbelt K-series canister. I feel that both are exelent vacuums on carpet. I have to try the Sebo parquet head with the front brushstrip removed. Just my opinions :) |

@Mike811 I am not saying that airflow is unimportant. I'm saying that only testing air flow will give you a misleading data. Just as a car must be tested with horsepower and pound feet of torque at the wheels.
If you just test horsepower that's misleading. Working water lift is the easiest way to test a vacuum. You can also do an air watts equation which requires knowing the water lift plus CFM plus math. Your video example is a very extreme example. @n0oxy I'd love to see pictures of that set up! |

I have noticed that the suction helps to maintain the airflow when hose is connected to the vacuum. longer hose and more suction is needed. That's why direct air vacuums don't work well with the hose, but performance directly from the cleaner head is good.
I will try to get the working water lift just to see how it relates to the suction and airflow. |

I wonder if it’s the unique design of the airflow path inside the D4 canister that causes weaker air flow at the end of the hose. Unlike the conventional Miele configuration with the fan just behind the bag chamber, the D4 has an angled path through the top of the canister, plus the danger of air leaking out if the seal between the cover and the main body (where the airflow from the cover crosses over to the air channel in the main body). Opening and closing the cover could always affect the cleanliness of that joint.
Plus the fact that the filtration chamber in the D4’s cover is quite large and could very well be dissipating any “oomph” from the motor. It’s an interesting air path design, but may be affecting cleaning performance at the end of the hose. |
