"I have the previous Heurist 360 and it is a wonderful device, in fact I signed up to buy this new model yesterday. ! also have 2 other Dyson uprights and a hand vacuum, apart from a few quirks, they are all excellent at what they do, and considering James Dyson has only repurposed a saw mill sawdust extractor system and not invented anything, he did it before anyone else, and now they all try to copy him. Great customer service, my robot cleaner froze once, I made a call and a brand new one arrived within 24 hours, free! What is the alternative? Samsung have had a go, and Shark, but they are not on the same level, Maybe as I am an engineer, I recognise what they are trying to achieve, and I can understand how thick people and housewives may get baffled occasionally as you do need product knowledge to use the cleaners properly. I would like to see less plastic and more aluminium or die cast parts to give the impression of being a bit more sturdy."
