I noticed that the original Gtech seems to have a bad rep for design and construction. Is the MkII equally bad or is it a big improvement?
The thing is that I think the fundamental design is good, with all the weight at low level. We had a Vax 36v cordless for a short time and I thought the design was ridiculous; with the motor and battery right at the top the whole machine is top heavy and surely a case of terrible ergonomics and the same applies to Dyson, Shark, etc.
It looks like Miele are aware of this because their new cordless has all the gubbins near the bottom of the pole - at a price.
It seems to me that the best design for a cordless would be to have a motorised brush connected to a suction tube and handle which then has a short flexi connected to a shoulder sling (or backpack!?) mounted "engine room". The flexi could easily uncouple to attach a crevice tool, dusting brush, etc.
Maybe it would look too "wacky", but it could be a good design!
