If I can get parts for a reasonable cost I am alright with it. For a Dyson V10 replacing all the common wear parts (battery, filter, motor, brush roll and contacts in the wand is just over $400 (nzd). replacing the wear parts on an old Electrolux (hose, motor, floor tool and bag) costs less than $300 (nzd). Bear in mind these parts are failing on dyson's after 4-6 years. On electrolux's they are failing after 30-50 years. If someone has money to pay for parts and labour every few years and doesn't mind the other disadvantages of dyson's and shark's can go right ahead and buy one. I notice that Dyson is pushing seasonal colourscheme's with their haircare line. Their slogan is "gift the colourway of the season". It would appear they may be trying to push yearly replacements. I may be wrong though. This is a bit silly to me as their top of the line machines (v16, gen5, v15 and v12) cost between $1500-1750 (nzd).
I love the feeling of an Electrolux with the ze3 that just glides about. I also like things like the generation series kirby's and the legend 2 as well. This is a bit controversial though I really love using a techdrive Kirby because in a little New Zealand home I can just whizz around And do the vacuuming so quickly. I just love that the techdrive does the pushing for you. I think it is definitely a learning curve, like riding a bike almost. When you are new to it you don't want to do it and find it difficult, then once you have learned it properly you can't get enough. I turn kirby's almost like doing a three-point-turn. Backwards and forwards a couple times. To each to their own though, if a Kirby if not for you that is ok.
