Ahh, the truth behind the new Vax uprights...
Just had a look on the Vax UK website.
It would appear that despite there being two cllps on the underside of the new Air3, you have to remove a single screw on the brush roll sole plate on the base.
The Vax cordless upright has a better idea though - two push in slip buttons that release the brush roll cover from the base.
