Any ideas on a portable washer/dryer? Brand? Suggestions? (USA)

My maiden aunt is quite old and ill, but she likes to keep busy. One of the things that she likes to do is laundry——but the problem is that the laundry is in her basement. She fell and hurt herself doing that and everyone is agreed that we need to do something different.

Her home is very small. There is no room for a full-sized washer/dryer upstairs. In the UK, however, we have portable washers/dryers (combination) that actually sit on the counter. We also have a regular sized washer that also dries in itself (in one unit, not like a stackable).

Because I don’t live in the States, I have no idea if you even make these portables that sit on counters or a dual washer/dryer that is portable that you can just plug in and move when you are done.

If anyone has ideas/name brands/suggestions…or even what these are called…I would appreciate it. I need some leads to begin some researching. Thank you very, very much!
