Ah, that brilliant inventor and designer Mr Dyson. I suppose the mechanism of the cleaner is clever, it gives a good suck, but the design of the extensions and tools make them very awkward and almost impossible to use effectively and without giving yourself a double hernia.So bad in fact, that he had to design a handheld vacuum to make up for it.... and sell you that too at ridiculous prices.
Can't be that daft though, made him a fortune and got him a Sir hood. Useless wazzock.
