While I'm generally a fan of simple appliances in concept, there are several significant changes that have occurred in the last 20 years you might want to just peruse.
As an aside, my dryer has wifi, but I only ever use that feature just to alert me on my phone that the loads are complete. I've never gotten that shitty software to actually start a load successfully. Not even upset about it, I didn't buy it for the wifi.
The internet of things is useless but don't let that hold you back from finding some really efficient modern technology.
I just bought one and you can even dry wool clothes in it without shrinkage. It’s also dead simple to use.
It usually took 3 - 5 hours to wash and dry a load, but it was ideal as a working solo Dad, I could put a load on before work, and it would be dry when I came home. Then I could put a load on before bed and it'd be dry in the morning.
Not sure who the average person is, but if they have a job, I found that very convenient.
For tumble driers, scroll to the annex of https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A...
"From 1 November 2015:
— for condenser household tumble driers the energy efficiency index (EEI) shall be less than 76,
— for condenser household tumble driers, the weighted condensation efficiency shall be not lower than 70 %."
(And then a definition of what that means.)
It's a front loading Panasonic in case anyone is interested.
The washing machine in my house does something similar, if somewhat less smart: put clothes in, tell it what kind of materials they are, it rotates a few times, figures out the weight and distribution then starts and tells you how long the wash will be. Certainly wish it had a heat pump mode.
I purchased the repair manual and gambled on the parts that I thought were the problem, plus a couple of cheap parts on either side of where I thought the problem might be. I was able to disassemble the washer, swap out what I thought needed swapping out, and I was done. Worked fine.
In poor countries, people don't buy new things as much, often are of lower quality and have less apprehension buying used if it's a good deal.
As I understand, our laundry habits are a bit different than much of the world. We tend to wash everything after one use and clotheslines are few and far between.
Also, our energy prices are cheap, so the pay-off curve for the efficiency gain of such a machine is long.
They'll probably get more popular as family sizes continue to shrink, and people continue migrating back to cities.
They exist in the US, so there must be a reason why they aren't as popular. I was outlining my reasons. Preferences are simply preferences.
What my time is worth has changed over the years, but what I'm willing to put up with has likewise changed. Yet, it's still valuable to know how to do basic things like top off fluids. Dont want to be stranded in the desert or a mountain pass if you dont know how to top off coolant, or seize an engine because your oil level is too low.
I dont do most of my maintenance any more, but I think its worth knowing the basics in a pinch. Adding fluids, jumping a battery, changing a tire, etc.
