I’ve got a Samsung washer / dryer combo unit; works great and runs on 120V, just be aware that a full cycle can take a few hours and due to it being a combo unit you can’t have one load in the wash and another in the dryer. Otherwise it’s a great unit and much better than dealing with the communal units in the basement. Installation was as easy as a dishwasher and no need to vent, exhaust gets condensed back into water and sent through the drain. Got mine at Costco for less than $2k.
