Miele Duoflex HX1 vs Miele Triflex HX2

“I'd sooner give the C3 a go, especially considering Miele's archaic bagless technology. As much as I love it, I'm cleaning out fine dust from my DuoFlex every use (with, ironically, a bagged vacuum).”

“This is up my alley and I do not see a true answer to your question. Between the Dyson Gen5outsize and the Miele TriFlex HX2, the Dyson is the far superior unit. The TriFlex falls short in a couple areas, with the main one being the bin and filter design. On top of being harder to empty, the Miele's bin only has one cyclone compared to Dyson's advanced multi-cyclonic design, so the Dyson keeps way smaller particles out of the pre-motor filter. The Miele is known for soiling filters very quickly. On top of the filters of the Miele getting dirty quickly, they also have a non-washable pleated pre-motor filter that is supposed to be brushed and tapped over a trash can, a design that was phased out by most brands in the late-2000s or early-2010s. Furthermore, the Miele has a non-accessible exhaust filter, which is absurd for the price of the unit. The Dyson has fully accessible filters that are simple for the user to wash and change. I will give the Miele some points for its "TriFlex" design, though. The way you can set the unit in different ways is cute, but the downsides trump the upsides for me. The negative aspects of the TriFlex models are so prominent that I am convinced that the only vacuum cleaner technicians who say they are good sell them in their showroom. Their bagged canister vacuum cleaners have a history of being excellent, but they have never released a bagless or cordless design that I would feel right recommending. As far as the Gen5 compared to other Dyson models, I would not say that there is a better one. The Gen5 lineup is the most recent, most revised, and most powerful. If you are worried about the size of the Outsize model, you can always go for the standard Gen5detect, but that is more of a size preference and not a noticeable performance upgrade or downgrade, aside from bin size. Assuming you were happy with your V8, you should get by just fine with a Gen5.”
