What bugs me about pretty much all the bagless machines and an awful lot of lower cost bagged vacuums are the cheap, hard, shiny, brittle plastics they are made of, crummy fasteners and the fragility of things you might want to disassemble for service. I have watched Dyson repair videos out of curiosity and always end up wondering what kind of, cough cough, "engineer" makes something with so many layers of stuff to remove, and three different size torx heads on the screws just to extract a motor. A reasonably adept person can completely disassemble a Miele canister in five to six minutes. Seven or eight screws, unsnap some parts, unplug a couple of plugs and it's apart on the bench. Same for a Kenmore. Their canisters come apart with four screws. On some two of the screws are hidden under a cord rewind pedal you pry off. Simple and fast. Their power nozzles come apart just as fast making routine service or repairs quick and simple. Plus the materials are better and they are designed from the outset to be taken apart easily for repair. But you just don't see that on so many modern bagless machines and especially those Dyson balls. So many little fragile parts and so easy to break, not to mention having to use different size torx bits. The most complicated modern canister vacuum I can think of is a Lux Intelligence / Aerus Guardian Platinum and I can have those apart faster and easier than a Dyson. Dyson, Shark, Tineco, everything you touch is this hard brittle shiny plastic that is to me offensive in its cheapness. Nothing like the materials you find in a Sebo or Aerus upright or canister or even a Kenmore canister ( the new ones from Suzhou Cleva are a big improvement over the old Panasonic made Progressives in material fit and finish ). The only bagless upright that even half way appeals to me due to its sturdy construction ( built on a steel sub frame no less ) and no nonsense design is the old Amway Cleartrak / Workhorse upright. As long as you strictly adhere to the fill line in the bin the filters stay clean and they last forever. But if you over fill one you have an unholy mess to clean O_O New ones are still being made, a testament to their utility and value.
