Seems odd that they have a huge robotic arm lifting the roof up and moving it across a hoover! I'm sure there must be some hidden logic but would it not be easier to move the small hoover nossle across the roof!?!
Like the fact that even his label printer is sporty... It was called an "Z4 M Plus"
Impressive process, there's no chance of me making a few of these in the shed anytime soon!
