Thanks, I presume you mean the large orange type filter that is at the bottom of the bag on the machine.
I am still torn between the two of them, I did like one feature of the G1 which I saw in a youtube video but Sebo couldn't confirm it worked this way.
The video shows the adjustment roller through the knob on the side, but unlike the BS36/Evolution etc it doesn't adjust until you turn on the machine and then automatically adjust to the pre-selected height. Is this correct?
I did look at the dart, didn't really like it. So it's back to these two models only.
Which would you choose then?
