Electrotruck, Use it within inner London and you wont have to fork out for the congestion charge either.
Only kidding before anyone goes and orders one. seriously attended the NEC several years ago and some firm were demoing something similar for appliances, only thing stopped me buying it was the £2500. price tag.
Limited use item, like all the rest. The video only shows it being used on a nice wide gentle flight of stairs. When you have a delivery into a Victorian terrace converted into flats and with a 90 degree turn at the top of the stairs its a slightly different matter… 😉
