Oh yeah. Have been for a while. I run into them a lot when I’m in Italy and still haven’t used one that worked well. Unless you want a load of laundry to take half a day. Then they work fine.

The new ones utilize heat pumps (GE Ultrafast, LG WashCombo), very different than existing ones in European countries.

There are but I have heard that sometime the dryer takes forever to dry... never had one though

They are popular in Europe and Asia but are somewhat less effective than separate units.

There have been for some time. There are some issues. A minor one: the max wash load is larger than the max dryable load.

A major one: the act of unloading and reloading gives you a chance to shake out tangles in shirt sleeves and whatnot. If you don't untangle your clothes you'll find they don't dry as well and can fatigue a lot faster!

Dryers are great if you live in the south where things won't dry on their own, or if you need to run laundry fast. If you can afford it, a drying rack works great, is cheap, and is far, far easier on your clothes.

I have one of these and I love it. Takes half as much space in the closet as having a normal washer and dryer and still finishes most loads in a little over two hours as long as I don’t put a crazy amount of stuff in it. I’ve also noticed the water usage is significantly lower than my previous HE washer. Mine is the “GE Ultrafast” one.
