Looking at getting a refurbished Dyson washing machine. Heard mixed opinions on them from different people. Whatís wrong with them?! I know they go faulty but is that cos theyíre mistreated or something? Also, if I do get one, how to I optimise itís lifespan? Finally, whatís the common issues to go wrong with them? Donít go too geeky please, I know nothing about washing machines!
