We see a ton of stretched belts and bad clutches. Filters are frequently mishandled when washed. Hoses frequently crack or tear. The ball machine is easily worn out- especially by people who don't care about their machines. We must remember that not everyone collects. Dyson is marketed now in big box stores- this leads to the reputation of being a more expensive "throw away brand." Even though it is more expensive, it still is not expected to last for any significant period of time. Like I have said before, people either absolutely love their Dyson or they hate it. Most of the people hate them and find them cumbersome and non-friendly to the user. We do have those customers of ours who love the Dyson and we would never talk them out of the machine.
As for the customers, I guess they think highly of the repairs. The average Dyson repair is in the $75-100 range. Every customer that has come in has either A) Gotten the machine fixed, B) Traded the machine up, or C) Abandoned the repair. I tend to prefer C since we have a 30 day policy on repair abandonment. No customers have walked out without taking one of those options. Dysons make great used vacuums.
We also need to keep in mind the number of Dysons that do NOT have to be repaired. I'm seeing 10-15 per week (in a large city), but there are probably a lot more out there that aren't being repaired or are not having problems. Regardless, it is a vacuum cleaner- and a decent vacuum cleaner. I just don't prefer bagless personally, and I think the exterior of the Dyson is bulky and cumbersome looking.
James Dyson has made a lot of money marketing this object, just as David Oreck did. I have both of them to thank actually, both Dyson and Oreck make up a great deal of our repair work.
