My Dysons never clog, I never had a vacuum clog in my life apart from an electrolux, even if I try to clog them up, and Dyson's never lose suction on me, I use them with care, they clean well, 10 years ago, approx 75% of my area in Birmingham where I live, used to be VAX owners and some Numatic, now about 65% of the owners changed to Dyson! I recommended my eighbour a Dyson, they got a DC33 multi floor which replaced a Henry and a vax 3 in 1, they didnt like the performance of the old vacuums, they LOVE Dyson, their neighbour has a DC19 origin, their neighbour is my uncle who has a numatic nrv200, I think, its the henry machine with a big base, and its called numatic instead of Henry and it has a push button, and also he has a DC04 Absolute, that works very hard, its abused, but runs like new, and my uncle's neighbour is my Dad's friend, he has a White DC14 All floors, and a White DC15 Allergy along with an original black Swivel Sweeper, My friend had to replace a vacuum every few months, I recommended a dyson, he liked the DC25 for it's ball, so his uncle bought him a DC40 multi floor, and they love it! he used to wash the filters every month, now he dont care and his brother threw it once in anger (Dont ask why, but its a sad story) and its ;like new! and finally, a good friend at schoo, he hated his Henry from 2005-2008ish tat it cant pick up pet hair etc, so he went to comet or Currys, Can't remember, and his cousin got a DC37, and he got a DC41 Animal, and he LOVEs hpow it picks up everything in one pass, even hair!
My neighbour's Dyson get's full every 3 Days, and once they borrowed my Mum's DC04 and they vacuumed only the upstairs with it, when they returned it, the Dyson had picked up nearly half a bin! I think I needed to replace the belt and wash the filters too.
Our house is 5 bedrooms, large family, 1 baby, 1 toddler, and 2 kids, and one teenager which is me. The Dyson never breaks down, its like using a Henry in a school, the Dyson never breaks down, When I use my DC14, the dirt it picks up it satisfying, the DC07 gets up LOADS of Dust and Dirt,, the DC04 lifts the carpet REALLY well, the DC25 grooms the carpet amazingly, the DC08 has amazing suction, the DC01 is a nice back up machine, it does groom well, but not the best
