Product review (4 stars): or a dryer vent are issues then this might be a good solution for you
Overall Review:

I've had this EdgeStar washer/dryer combo for a year and decided it was time to write a review about it that hopefully answers some of the questions/concerns others have had about this product.

The first thing you have to remember is this solution is a niche solution and not a direct replacement for a stand alone full-size washer and dryer.  This runs of 120v, doesn't require a dryer vent, fits under a cabinet, and is both a washer and dryer in one unit.  The quote I had for plumbing my condo for a full-size washer and dryer was about $5,000 compared to the cost of one of these units.  So if plumbing, electric, space, or a dryer vent are issues then this might be a good solution for you.

Yes, it takes longer to dry because its 120v. Yes the capacity is smaller than a normal unit but again see the last paragraph.

A full cotton/normal wash cycle and dry is about 3 hours. It isn't that big of a deal with a little planning.  I can kick a cycle off before I leave for work and get 1-2 cycles in at night.

In terms of clothes being wet after a cycle all I can say is that hasn't been my experience.  Yes if I pre-soak a towel or two and then throw them in wet it will take a few dry cycles.  However, if I load the machine up about 3/4 full and let it run then everything comes out almost completely dry.  If there is a little moisture left it dissipates quickly.

Even if you don't add a dry cycle (you have to specify otherwise it just washes) the clothes are a little damp but not soaking wet.  You could hang them and they would dry quickly.

I will say that for 1-2 people in a household this is probably adequate but if you have a family you'd have to be running this unit 24/7 to keep up if you're washing and drying with it.

The big draw to me was the cost savings over plumbing/buying full size units, I can wash almost everything, and I don't have to constantly run back and forth to the laundry center on the property.

Install Notes:

Be aware that many plumbers I found were not familiar with this style of unit and were very apprehensive about installing it so I ended up doing most of the install work myself.

For my install I did a tee off my sink's hot and cold water line and ran them into a traditional washing machine outlet box.

The output hose is the same as a dishwasher hose.  My dishwasher ran into the disposal so I added what is called a tailpiece pipe for this to drain into.

Once the plumbing install is done everything else is easy.  The electrical cord is a standard 120v so no issues there.
