Earlier quoted context omitted.

Yea, it's weird reading this thread to me. I have a cordless Dyson vacuum and it is by far the best home vacuum I have ever used, both in terms of suction power (even compared to non-cordless ones) and in terms of other usability/features.

I think Dyson benefits from the same effect as Apple/Tesla/Beats/etc. Their products are good but their triumph is upselling. Dyson cordless vacuums are like $800+, was your previous one that expensive?

Perhaps, but just like Apple they have a refurbished category where you can get very good deals - and that's on top of them having sales regularly.

I should add that I called Dyson once for my 7 year old wireless vacuum which was having battery problems. They mailed me a replacement completely free of charge. The upselling might be there, but the up-service also seems to be there.

Technology Connections did an episode on air humidifiers a while ago: https://www.youtube.com/watch?v=oHeehYYgl28 The fan and filter size matter the most. Most of these things are hugely overpriced for what they are.

After watching his dishwasher episode I lost all respect for him. He clearly forced that episode and his conclusions were predetermined so he could have a clickbait video title/theme.

That's interesting to me because I've had the opposite experience.

I move a lot. For almost decade I moved twice a year. I don't like taking the dirt from one place to the next, so I buy a new vacuum cleaner every time. So I've been though a lot of vacuum cleaners.

I've tried every brand and almost every level of vacuum cleaner on the market, because sometimes I have more money to spend on a vacuum cleaner, and sometimes things are a little tight, and I have to get a cheaper one. The two Dysons have been the best of them all. My only complaint is that with the wireless models, the battery doesn't last as long as I'd like, but if I stick it back on the charger while I'm moving furniture out of the way in the next room, it keeps up well enough.

I bought an expensive Dyson air purifier for a couple of reasons. It has a remote so I can turn it on from bed. It looks attractive. The sound profile is much different than a box fan for sleeping at night. It can analyze the temperature, humidity, and air quality in real time and turn on if it notices air quality is getting bad. It also oscillates. That said yes it was expensive, but it replaced needing a fan for co…

It's obviously popular to hate on silly-expensive tech, but these quotes were telling for me: > "I think what we're trying to do is pull back a little bit from the CADR metric," he said. "Not everyone needs an enormous CADR, has huge rooms or incredibly dirty air." > Several experts told Marketplace the CADR is the most important metric and an internationally recognized benchmark. > "CADR is what you want to know, pe…

Exactly. Like dB.

Same as "processor speed is all that matters"... well, not. I honestly would gladly pay more for a QUIET computer (they are become more available).

After watching this segment, I immediately bought a 20" box fan, a 20x20 MERV 11 filter, and put one together. It kicks the pants off of air purifiers twice the price and it moves a lot of air through. Best investment ever. CBC was testing CADR, which is one metric among others, but an important one if you're looking to clean a room's air, fast.

I've used a box fan with a 20x20 filter for years when I'm doing woodworking, but it's a little too clunky of a solution to use in my primary living space.

I love the fact that Lasko has decided to own this concept with box fan designed specifically for this setup. It looks much better than a filter taped to the outside of the fan. Maybe this would help with your decor vs cleaner air conundrum?

I still cannot get over this product. They whole selling point of a dyson fan is the 'air multiplier' tech, which creates a low pressure zone that propels air through the ring. According to dyson, this tech can move 15x more air than the fan in the base of the unit. Why in the world would you build an air filter around a system that does not directly interact with 93% of the air it moves? https://www.jameco.com/Jamec…

> Why in the world would you build an air filter around a system that does not directly interact with 93% of the air it moves? Dyson fans produce a continuous stream of air. Regular fans produce choppy air. I don't think anyone actually notices this effect until you point it out though.

The “choppy” air is the effect that you get when you are close to a fan and you talk into it. This diminishes significantly at very short distances.

If you’re at a distance where you can talk into the airflow and sound normal, you’re probably not experiencing “choppy” air.

The public bathroom air blades drive me crazy. It keeps splashing the water back and forth, the air speed is too high and my hands inadvertently touch the sides and probably there are a bunch of germs circulating inside, as not everyone washes their hands thoroughly. The old school super blowers that just do hot air down, or whichever direction you turn, probably consume more power, but certainly dry my hands faster…

Protip: If you're in a public rest room and there are two hand dryers next to each other, use them both at the same time. One for each hand. Much faster.

The nonsensical Dyson canister vacuums are the ones that amaze me. Dyson competes based on premium coolness, so just consider at its primary coolness competitor: Miele. Across the board, Miele canisters are lighter, more powerful, cleaner, and much more effective than their Dyson cost equivalents. They have a far lower failure rate and last much longer. Bagless canisters have so many negatives compared to bagged vacu…

Do you have any more info to back this? I am honestly curious- I bought a Dyson Animal about 12 years ago now, and its still going strong, and is the best vacuum I have ever used. Not having to keep bags around is nice too. Our usecase is relatively light- we have area rugs mostly, but its still head and shoulders above the previous vacuum we had, and any of the ones my parents had growing up.

One thing I particularly appreciate about our Dyson corded vacuum is that I can take the whole damned air path apart if needed, without tools. It's quite useful when something gets jammed up in a u-bend. I have no comment about the rest of it, compared to other ones, because I haven't had to replace it since we got it a couple of decades ago.

> One thing I particularly appreciate about our Dyson corded vacuum is that I can take the whole damned air path apart if needed, without tools.

the first time i went to clean the filter in ours, i kept seeing that i could easily take off/remove one more thing, so i did. next thing i knew i had completely dismantled and washed it.

then it went back together just as easily. hardest part was waiting for things to dry out.
