> I don't like taking the dirt from one place to the next, so I buy a new vacuum cleaner every time. That seems extremely wasteful. Why not just emptying the vacuum cleaner before bringing it to the new place? One person buying 20 new vacuum cleaners in a decade is just one of the reasons this planet is running out of resources.

That seems extremely wasteful It is. I'm not afraid to admit that. Old vacuum cleaners give me the heebie jeebies. We all have our quirks.

Do you sell them or give them away? Tell me how you haven’t thrown away a whole series of functional vacuum cleaners.

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…

Don't underestimate the placebo-effect of having a Dyson, regardless of it's physical effects. This is what you can do with a premium brand.. only a Dyson is like a Dyson

I am surprised that so few people discuss the centralized, presumably less-wasteful, less-cluttered alternative that is a furnace-adjacent air bypass + filter (particularly relevant for those of us with access to our own fans/furnaces). The idea, as I understand it, is that a furnace can be modified by an HVAC specialist to send a portion of the air through a low-flow bypass duct containing a HEPA filter (or some oth…

Just buy a high merv (e.g. merv 16) filter and you'll be good. No need to move the HEPA. Most modern hvac systems can support high MERV filters and doing this will significantly clean your air.

> "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."

It seems plausible that CADR is becoming just a bigger number without improving effectiveness, like megapixels.

It also seems plausible that Dyson is just struggling to avoid commoditization because it's a losing battle for them. And it's possible some of that has merit, because running a noisy fan when the air is already clean seems annoying.

They’d probably only do it once. It builds character, similar to == in JS or PHP.

Says no one who has ever raised kids.

I mean you can tell you kid 100 times not to touch the stove but they don't lean the lesson until they actually try once when you're not looking.

I thought that until I came to own a dyson ball vacuum for free. My lord. If a hoover/shark/whatever is a 25 year old toyota corolla, this is a brand new rolls royce and feels like it. It's extremely powerful despite being used, and collects a frankly disturbing amount of dust and hair every time I use it (picking up about a full chamber of hair from my longhair cat some times, hair that was invisible to the eye on t…

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…

Compare to your furnace (on fan mode) + air filter ...

> It has a remote

Check

> It looks attractive

Check. It's invisible.

> sound profile

Check. Furnace fans are in the garage.

> analyze the temperature, humidity, and air quality

Nope. But purpleair will sell it to your for $175.

> oscillates

Check. Covers entire flat.

All I know is the two vacuums we have. Both have absolutely exceeded expectations. The first was a wedding present in 2005, and it still works GREAT -- we only bought the 2nd (a cordless model) to avoid lugging the big one up and down stair so much.

I absolutely would buy another Dyson if either of these failed or broke, no question. We're super happy with them.

My wife rigged up a similar box fan + HEPA filter + duct tape solution during last summer's CA wildfires. They are remarkably effective. We also have the BlueAir purifier that was top-rated in this report, and arguably the box fan did better. (The BlueAir is better for kitchen smells, the box fan is better for particulates like wildfire smoke.) I think the filters are like $40 each from Costco and the box fan was $30-40, so it totaled about $70-80, about the same as the jury-rigged solution in the article.

Highly recommend this solution if coolness is not a factor.

We must have had a dud as we got the Dyson animal hair one and it was terrible. Battery life was rubbish, the suction was crappy and the pick up just wasn't that good. Ended up getting a gtech which was fine for 2 adults in a small 2 bed house with wooden floors, but now we have kids and a bigger place we got a Shark corded and it is amazing. Literally the best vacuum we've ever owned.

FWIW, we have six furry animals of our own (with four different hair types) and also foster and board dogs. We never buy the “animal” cleaning machine. I’ve never seen a product that in any way shows it’s somehow more capable of dealing with hair or messes than other products in the same line. I have had them be more expensive and flimsier relative to that same line though.

The "Animal" product line is identical to the regular product but comes with a few additional attachments (powered hand hair brush) and is a different color. We have a Husky dog that blows her coat twice a year, 2 longhaired cats and a shorthair. The machine is amazing.
