Numatic could well be making the compact model with a smaller dust bag.
Also in response, or rather to back up with Benny has said, an example of another model I owned springs to mind also by Numatic - the Charles wet and dry model. I owned one for a few years. I adored the power and I appreciated the massive 15 litre dust bag, more so that ONE bag seemed to last a year and a half when used solely as a home vacuum.
But oh how I missed the Bowler hat manual cord winder! Again whilst this reiterates that Numatic can make a good vacuum, I didn't half lust over having the hand cord winder instead of having to manually wind up the 10 metre cable after every use with Charles, and like the James vac I also had, Charles also had the awful difficult to remove aluminium tubes compared to Henry's easier stainless steel ones.
