Yes.. bought a Miele Complete C3 Auto Comfort Boost getting on for a decade ago. Really nicely designed. The one bit of 'questionable' tech it has is a remote control in the handle for power and controlling the suction level.

However you quickly realise that's logical, as otherwise you'd need a second cable, or to embed it in the tube somehow.

What's less defensible is not duplicating the +/- buttons on the vacuum itself, so if the coin cell battery fails you can only turn it on and off.
