Dyson is an expert in producing overpriced vacuum cleaners (we had one - once, never again);
electric cars depends upon battery development.
We have had Dyson cleaners, both mains and battery. Excellent cleaners, cr@p batteries. Battery lasted just 2 years, and costs £70 to replace.
With the latest model Dyson claims a 15 year battery life, but only offer a 2 year warranty, so we are not convinced.
