SEBO Vacuum Bags and Filters 

There might be a slight measurable difference in air flow, however when we start talking about machines of this caliber, the difference in airflow are not noticeable in the real world. We demo these guys all day and you truly can't tell the difference in performance. More than anything at this point its a decision between usability and features. The D4 tends to have better longevity due to the larger bags and filters: these prevent back pressure on the motor. There is also better motor protection in general on the D4 which prevents debris from breaking it down. Since the bags, which cost about the same as the E3 bags, also last longer they are essentially cheaper. The post filters are larger and therefore also last longer on the D4. The swivel hose design on the D4 is easier to use for people who might not be used to a canister. The D4 is slightly heavier than the E3 due to these features. If you would like a full list of each of these machines feature sets, we do have that on our website as well. Feel free to reference that! www.vacuumsrus.com/product/cleaning/vacuumcleaners/sebo/sebo-airbelt-d4-premium-artic-white/ or www.vacuumsrus.com/product/cleaning/vacuumcleaners/sebo/sebo-e3-premium-onyx-black-with-10-yr-parts-7-yr-labor-warranty-et-1-powerhead/

They do not open automatically, we occasionally forget things while filming videos this large! To open the lid, the latch is right under the lip. If you look for the indentation of the handle on the top of the vacuum its pretty easy to spot.

@@vacuumsrus Thank you for the info. I was just curious; I hope it didn't seem like I was being negative.

Helpful info for sure. Minor note: the bag installs showed the bag debris flaps closed when the lids were being closed. Shouldn't those bag flaps be __open__ so air can flow into the bags during vacuuming? On the Felix, you did show that.
