In reply to Sharp:
....never really understood the Dyson hating brigade, what more do people want from a vac?
I'm tempted to guess that like most products these days, some work OK, and some are utter dogs for some reason or another.... We've just ditched a Dyson that never impressed. It was OK for first few months (but not life changingly good as many seem to claim or have indeed experienced)... and after that it got steadily more useless. Its plasticky, bulky and despite lots of careful cleaning of filters and so on its hopeless. What use is bagless if it doesn't pick up and needs its filters cleaned (not that cleaning them has ever made any difference).
So - having looked at loads of reviews of all sorts of things I'm coming to conclusion that bar 100% useless cheap gadgets which are genuinely 100% rubbish, most other consumer items now are badly and cheaply made and its luck of draw if you get one that's good or bad. Look at reviews for most things and you'll find on so called 4 to 5 star happy ratings at least 20% of people stating doesn't work/fell to bits/wore out etc etc. Reviews are also skewed by people reviewing when bought, praising price/delivery, how it was out of box etc and then not going back in 4 weeks or 6 months to say it stopped working, wasn't terribly good etc. Appreciate you have experience of being happy long term so that's not the case here but much of above holds true.... I just think with dodgy cheap manufacture outsourced to wherever that quality control goes, that the things are made as cheap as possible and the result is real variability in quality and reliability from 'great' to 'rubbish' in same product.
As an alternative - I have an ISE washing machine... 10 year warranty, everything is replaceable and recyclable and it runs for example on Volvo Truck bearings, rather than cheap nasty plastic ones. That's a product built to last and built to be recycled at end of life (metal weights rather than concrete on basis the metal recycles more effectively rather than just being landfill) etc.
Still don't know if I've solved vacuum issue but we went with Henry and so far am very happy at about a third of the cost of a modest Dyson. We shall see in 1 3 and 5 years hopefully.....
