So you can leave your clothes in one machine, and in two hours everything is washed and dried.
But now I have to wait two hours for each load of laundry, versus 45 minutes and swap between machines. They have effectively more than doubled the time laundry takes.
Who thought that was a good idea?
I did not buy an all in one. I was just saying that they don't make sense to me.
I'm allowed to have opinions. I'm a human.
I am one of them, so I am happy to use a combined washer and dryer.
The only place where I can put the washer and dryer is in a bathroom. Separate washer and dryer would make it unacceptably crowded.
(e.g. this kind of arrangement: https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2F... )
On the other hand, I do have limited space for appliances, so in many places I've lived buying a seperate washer and dryer would mean either forgoing a dishwasher, or getting a condenser dryer and installing it in the corner of some random room away from the other appliances (which would technically be a code violation as then it wouldn't have its own dedicated RCD).
So I get a combo unit, turn it on and forget about it for several hours (when I'm home all day, I even use the eco mode, which takes 6 hours for a combined wash and dry). Come back later in the day and unload. It actually does have a 60 minute wash + dry cycle but I rarely use it as it uses a very hot dry cycle which risks shrinking clothes.
I only load and unload clothes once (not twice).
I only program a machine once (not twice).
One big feature my LG has is it will keep rotating the drum a half a turn every few minutes, so you can take the dry, clean clothes out much, much later, and they will not be wrinkled.
As others have said, if you're limited on space in your house it's a bonus. In my case I converted the space that would have been taken up by a second unit stacked vertically into large storage area with shelves.
Nearly all appliances have a „quick“ mode though if you really need something fast.
These machines would double that amount of time, because I couldn't run the dryer at the same time. That's what I'm saying.
