That works both ways, Josh. If you want people to be more accepting of the pro's, you have to be more willing to accept the criticism.
I've said this before, people form their opinions based on experience. I'm never going to be a Dyson fan. I don't like bagless vacuums full stop. But I didn't just wake up one day and decide I wasn't going to like them. I haven't just thumbed through an Argos catalogue and gone "nope, don't like that!". I've formed my opnion on YEARS of use. Heck, I've owned a heap of Dyson's myself.
The first time I ever saw a Dyson was very early on. My uncle worked for some electronics company and he got a DA001 for my aunt. I spent a whole afternoon at their house playing with it - I was only about 4 or 5. I then spent about 6 months trying to persuade my Mum to get one. I thought it was so cool. It wasn't until years down the line when they were becoming more mainstream that I started to notice the drawbacks and it wasn't until I'd owned a few myself and used them in my home that my dislike started.
I think they're very overpriced for what they are, I don't think they do a particularly outstanding job, I don't think they're very well made at all, I think the high price tag you pay is reflective of the R&D that's gone into refining the cyclone and not a reflection on the quality, performance or longevity of the machine, I firmly believe that the success of the company is a result of clever marketing gimmicks and not actual product and I don't think they're all that nice to use -difficult to get under furniture with, the tools are a faff having to completely stop what you're doing and disasemble half the machine just to use the hose, unhygenic filter washing (although not an issue on this machine) and I don't care what anyone says there is an inevitable dust cloud everytime you empty the thing.
Those aren't opinions that you just form overnight for no good reason. They're reflective of my experience of owning and using Dyson vacuums.
I know you're happy with your Dyson and that's great! You've found something that you believe is doing a great job and works best in your home and circumstances. That's what vacuum shopping is all about! But just because it works for you, doesn't mean it does for everyone. I think it's absolutely important to keep an open mind, and that works both ways. For example, I would have no problem recommending a Dyson to someone who wanted a bagless vacuum and indeed have done on many occaisions to friends and family where bagless has been the requirement. But take away the bagless aspect, I firmly believe there are better, cheaper bagged vacuums available.
You may get frustrated with people "not giving Dyson a chance", but I get frustrated with anybody having Dyson blinkers on and constantly focusing on them, talking about nothing else and refusing to accept the flaws. No vacuum is perfect.
