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…

Reminds me of newer appliances (such as washing machines/toilets) that brag about water efficiency yet don't do nearly as good a job, requiring a second cycle, thus using more water.

I did recently buy a HE washer to replace the junker that came with the house. It may just be that I live a (mostly) white collar lifestyle, but I do make a mess of clothes I wear for renovation and yard work or for camping.

So far, the new washer hasn't given me any issues with getting things clean. The only adjustment I had to make was learning to use much less detergent than I was used to.

There are also just two people in the house and no kids, so perhaps it's more of an issue with larger loads or more grass stains, etc.

My neighbour used to have a Dyson leaf blower.

I would wake up thinking I was in the men's room.

But isn't using a fan too long in an enclosed room dangerous? https://en.wikipedia.org/wiki/Fan_death

No. This is yet another urban myth. "Despite no concrete evidence to support the concept, belief in fan death persists to this day in Korea,[further explanation needed] and also to a lesser extent in Japan.[1][2][3]"

I'm sure the comment was sarcastic.

I prefer the Excel XLERATOR hand dryers, and usually spec them over most other models. Hands dry in ~10 seconds, not spashing onto a lower surface, etc.

I hate them because they are too loud. Sure they work fast, but I need to put air plugs in before using them, and those are never provided.

To the downvoters on wincy's comment: please let's not downvote people for asking questions, or just because you believe they are misinformed -- that's what replies are for.

You shouldn't downvote people for asking questions, but asking a question and supporting it with a link that tells you the answer is fair game, especially when your "question" is an argument hidden behind a question mark, and the link disproves that argument. There is, of course, the possibility that wincy's comment was meant to be tongue-in-cheek, though. I personally can't quite tell which way it was meant.

From the HN guidelines:

Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.

I'm surprised to hear that sentiment about the vacuums in particular! I found the v11 I bought to be vastly better than previous vacuums I've owned, with excellent power despite being cordless, really light and much much quieter. I haven't used any other Dyson products; I opted to buy Rabbit air purifiers over a Dyson Air.

Miele. Every Miele I've found is superior, hands down, to its Dyson equivalent.

Maybe true for corded vacuums, but the Dyson cordless models have superior battery life.

For a "wired" vaccum, i'll go with Festool every time, but yeah, Dyson wireless vacuum are pretty good.

People are talking about the household vacuum type (upright & cordless) not shop-vacs or dust collectors.

My household vacuum cleaners have almost always been corded (with the exception of a couple battery powered ones I had 5 or 10 years ago). Granted, I didn't shell out several hundred dollars for the cordless ones, but dead batteries and replacements got old after the first round so I've stuck to corded ever since. It's just not something I ever really had a problem with. The cords are typically quite long and I never have to worry about battery capacity or lifespan.

Yes, we have the vacuum on a stick at work. It's a cheap plastic thing that looks like a sex toy for Buck Rogers and it doesn't perform nearly as well as the Numatic Henry we have at home.

We also have a Real vacuum (the numatic, we have a George but same thing), as well as a dyson v7.

The dyson's are bagless but they have to be emptied all the time, and the maintenance is a lot more of a chore.

I think the ideal mix would be to have a cordless dyson but with sort of a base that empties into a bagged vacuum, similar to the robot vacs nowadays that empties themselves and have a bag that can be thrown away once a month.

Having to empty the dyson every 3 days sort of defeats the point of having a HEPA filter for allergy viewers.

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…

We're also in the same boat. It's something that stays out all the time. It's just unsightly to keep a box fan filter out all the time (we used one when we first moved out, and man, the back of the filter gets disgusting).

Looks do matter, and at least for our decor, there isn't really much choice. We pick our furniture based on how it mathes our interior decor, why would an air purifier be any different if it's out and on all the time?
