dysons are a bit complex but robustly built and endlessly and cheaply repairable, henry’s have hardly any moving parts. less to impress less to go wrong. both are only vacuum cleaners. The repairability of Dysons might be something I think a lot of owners overlook, as we’re now in a culture of if-it-breaks-buy-another.
In upright form dysons are excellent if theres a lot of crud to deal with – pet owners, people with real fires etc – I bought one when a client for an office refit decided to have new carpets fitted before he asked me to build the partitions, walls and ceilings. Non of my uprights and cylinder vacs couldn’t lift the carnage left by the plasterers but the dyson could. Using the hose and tools on the dyson uprights is an arse though, I find them rubbish on stairs and in small tricky rooms, the handle/hose is just too ungainly, and as much as they do 95% of the job quickly and brilliantly you’ll be yearning for something more nimble for the final 5%. They’re also really noisy, especially on hard floors.
In cylinder form theres not that much to choose between them performance wise, they are just different ways of achieving the same goal, its just a case of you wanting to convey the image of being one of either being one jetsons or the office janitor, choose your fantasy.
Meile make a nice noise, but for that price tag I’d want it to be my job to hoover all day to want to pay to listen to it.
