Mine… My Xbox 360 slim only costed 129 euro back in 2012 and to this day still work like brand new, you would think that the disc drive would stop working but no. Never had the need of open it or clean it’s insides. Still great, I just don’t use it anymore since I feel it’s outdated and loading speeds are better nowadays.
the driers are self explanatory and you don’t have to bother with anything beyond plugging it in if you get a ventless designed dryer.
this video shows how you can connect a portable washer to both a kitchen sink, like i do it, and to traditional washer/dryer hookups.. there are many different styles of portable washers; the smaller ones are more affordadable; but their small size limits their usefulness and this video only focuses on the traditional sized ones.
this one seems to be a decent AI generated review of the smaller/cheaper ones.
