Vacuum Cleaners Discussions

The bag is not huge.

What you are not seeing because of the grey central bag-door handle and logo trim, is that the paper bag is offset to the right of the central trim (look at the hose entry point, the bag sits directly below this).

On the left side of the cleaner (looking at the photo), the "bag" in this case, is actually the tubular motor-protection microfilter.

You cannot see that there are two separate entities, due to the trim blocking the view.

Excellent points and keen obersvation skills.  Thank you for pointing them out.

Hello Carmine, you're welcome.

Well the bag is big enough - standard fit 5.5 litre/6 litre capacity which is similar to Miele's S7.
Don't forget guys that although Sebo are in the U.S they also the old X1 Automatic under the Windsor tagm Windsor Sensor models infact. I believe there's a Dart model too, commercial version of the Felix under a different name too.

The great thing about the Sebo design is that the bag doesn't cover the pre-motor filter, so the motor's not having to pull air down through the bag. The filter is at the side, so the suction stays 'stronger for longer.' When you empty the bag, it's solid like a brick, packed right to the top. When you put a new one in, it's amazing how much lighter the cleaner feels!

Model2:

Is your point that a vacuum's motor, not just SEBO, pulls the air through the bag?  Would you mind explaining to me how that works?  I thought the motor pulls up dirt.

Are you asking me to explain the clean-fan (as opposed to the direct-air/dirty-fan) design principle? Or the difference between Sebo's pre-motor filter design (placing the filter's huge surface area beside the bag - see diagram) and the more commonly-seen design, whereby the pre-motor filter is located under the bag?

hi Model2......wouldnt  panasonics optiflow system not produce the same results as the sebos side intake...or riccars tandem air set-up is similar as it has the side intake..diff system i know but same idea...increases of suction from that side intake are how much over the optiflow or any other bottom type? not looking to debate...just curious.

Other brands may well have similar designs; I'm not claiming the Sebo is entirely unique (although I can't think of anything else on sale in the UK with a similar set-up), I was simply making the innocent comment that it's one of the Sebo X-series' strengths that the suction stays relatively constant as the bag fills. That's all! Sebo have been on the mainstream market in the UK since the early 90s. 'Which? Magazine' currently rate them as the most reliable upright brand, and the highest upright brand for customer satisfaction. 'Which?' rate their performance as rather mediocre, which concurs with my own opinion of them. However, I do find that the power stays relatively constant as the bag fills.

I'm not familiar with the Panasonic Optiflow system, so I couldn't comment on that. Could you post a diagram which shows how that works? The core principle of the Sebo system is that the bag doesn't sag over the filter as it fills with dirt, so the motor's not compromised pulling air down through layers of whatever dirt's already in the bag to a filter smothered underneath. If the Panasonic system is similar to that, then the answer's probably yes. The Sebo doesn't offer extra power over other machines, in fact, I feel it's weaker than many. It just stays at a more constant rate as the bag fills, for the reasons I've explained.

Model2:  I didn't mention direct suction dirt path and/or by-pass dirt path cleaning [as is the case with attachment cleaning].  I'm asking how a vacuum motor, SEBO or any other vacuum motor, pulls air through the bag into the motor and at the same time pulls dirt into the bag.  How does that work?  Explain it for me, please.  The diagram you posted is the dirt/air path to the bag not the air path to the motor.  Am I right?  I see no filtered air pulled through the bag and going into the motor.  I see air leaving the bag and going into the dirt path nozzle.  Do you see that too in your diagram?

You posted WRT the SEBO pulling air through the bag by the motor:

Your post and the diagram appear to be contradictory.  The diagram you posted shows no air pulled into the motor from the bag.  Is your point that other vacuums do this [pull air through the bag into the motor], but SEBO doesn't?
