Interesting observation on this thread. A lot of comparison of Dyson to Kirby but NO comparisons of Dyson to Aerus/Electrolux. Hmm seems to me there is no comparison. Aerus is just far superior...lexan virtually indestructible plastic. Versatile combination attachments. Warranty...ease of use, longevity...ease in emptying...the list goes on...every Dyson I’ve tried is no comparison to even my 35 year old Electrolux Silverado. Yes the Aerus’s and US Electrolux’s may lose suction due to the bag filling with dirt but a Dyson does require the nasty filter cleaning. The aerus Electrolux is simple to change the bag and the dirt is sealed in and every time you change the bag suction is fully restored. I just consider a Dyson nothing more than an overpriced big box store vacuum. I’ll give it the best bagless design for preventing dirt from clogging the filter but it still will happen over time just a longer time than others. I used a Dyson upright and found it very heavy and awkward to use on carpet and couldn’t get under any furniture period. Tried a canister and the rotating brush nozzle was turbo driven and a very poor performer at that and the suction on the canister even with a clean filter was just so so. Some of the attachments were already broken in this 2 year old Dyson canister. Tried a practically new Dyson ball upright. An underperforming product for the price. Still heavy...still couldn’t get completely under furniture only the nozzle head partway and it was generally awkward to use and forget easily switching to attachment hose mode...rather frustrating.
Being a person who cleans very thoroughly in all the corners, along the tops of baseboards, cobwebs up high, bugs and dirt in windowsills, crumbs and pet hair in couches and furniture I still find the Electrolux or Aerus especially the canister models the easiest and most versatile to use to switch modes fast and deal with the dirt the machine has collected is never never an issue. I do t see the dirt, touch the dirt, or breathe the dirt. A Dyson bagless, the dust will still always cling to the outside of the plastic bucket when you empty it as this is a static electricity issue requiring the step of now wiping the bin down with a wet rag or paper towel...and if you are remotely worried about allergies or breathing dirt, you have to go outside to empty it and wear a dust mask. Yeah I might not have to buy bags but I have to buy dust masks and use paper towels.
And Dysons plastic brush roll bristles are hard and can damage some carpet. The Aerus Electrolux power nozzle which is also on their upright is self adjusting and I’ve never come across a carpet thick or thin, low or high pile, it won’t clean nicely.
I’m glad I never wasted money on a Dyson and I do not recommend them to anyone who wants a vacuum brand recommendation as most people know I like vacuums. First I recommend the Aerus Electrolux and if they don’t want to spend that much then I just recommend some of the newest Shark products. Both US companies interestingly enough though not necessarily all built in the US.
