+1 for steel ball brgs vs plastic when replacing failed ones.
Vacuum cleaners are a throwaway product these days and are always built down to a price like all mass market appliances. If they last the warranty period length plus a couple weeks that is mission accomplished.
Dyson's real achievement is a marketing and advert campaign that convinces people that their vacuums have better or more "leading edge" technology than other brand appliances. Take one apart and you will see very little actual technical innovation, but lots of visual gimmicks with transparent cones, funnels, bits going around, and lots of inaccessible areas jammed with dust and lint.
Their stuff may be designed in UK but look at the boxes and it is made in Thailand and Malaysia.
I'd say the best empty catchphrase they have gotten away with is advertising they have a 'digital motor'. Digital motor control circuit, sure, but 'digital motor', that's just marketing / advertising hot air.
My opinion only – Just my $0.02 worth – your mileage may vary.
