The Sebo can lay flat to go under beds whereas the DC75 has a ball to get into corners and around furniture quicker
The list goes on...
The Sebo Felix range also has ball like maneuverability. In fact, Sebo did that first.
The last DC75 we sold the woman brought it back the next day and went off with a DC33 instead.
Oh yh forgot about the Felix, I want one of them and an X4
I have lost respect for the DC33 sadly, they just seem crap IMHO if used in a big family home (filters get dirty quickly and loses suction quickly being a main flaw) and in use they are really flexible vs my 41 which surprisingly feels more solid when being pushed around in use :/ It's like kind of like Vax copied a DC14 and produced the DC33.
I know the DC33 and DC14 use the same cyclone technology, but I'm not sure how much longer the DC14 suction would last vs a DC33 as I normally clean my machines up every month or so
