Sorry, no experience of the cordless stuff. I run a commercial cleaning company so my criteria is durability, cost and ease of repair. I probably own around 60 Numatic/Henry vacs because they're tough enough to cope with all sorts of abuse, can be easily fixed if the do break and can be picked up for around 100 quid. At home we have a Vax upright which is superior to the Dyson in every way.
