A note about washer/dryer "portablity" and portabili
In my experience, most of the washer/dryer combos are not--per the manufacturer--designed to be used as "portables". No current LG washer-dryer is designed to be used with casters, for example.
While a number of resellers do offer "portability kits" which largely consist of casters to replace the normal legs and a faucet attachment kit, using casters is problematic with a front-loader; the casters do not provide a stable base and significant vibration during spin results.
--I had a Equator for about 12 years and--while it was on casters--I used custom foam blocks to anchor it between the end of the counter and the wall so that it was stabilized. Without that step, the castors were not sufficiently stable: any spin was unstable, loud and I can't imagine that it wouldn't have eventually damaged the machine.
--When that machine died, I replaced it with an LG Combo (bigger, faster, stronger, shinier). Due to the layout of my apartment, I need to be able to easily move the machine, but instead of casters (which LG explicitly says not to use), I used an adjustable shop stand base (HTC2000 Adjustable Mobile Base to be exact). Because it is designed for shop equipment, it is extremely stable. In the lowered position, it is firmly anchored, and it raises easily with foot pedals to allow it to be moved. I leveled it on the stand in the location I used it and the even heavy load spin cycles are amazing smooth. Pic below.
--Note that when connecting to a faucet, you adjust the temp by adjusting it at the faucet itself. It gives you complete control over the temperature, but you have to remember to change to cold only for the dry cycle.
--I get the impression that most of the people saying how useless a 120V combo dryer is have never actually used a combo unit. Most of my loads dry in an hour including towels (note that if you do a full load of wash, you need to split the dry time: this is more due to the small drum size--dryers normally have double the volume of a washer to allow airflow). So if I do a full size load, it usually is two 1 hour dry cycles for drying each half. The new LG dries faster than the old machine. It isn't as convenient as a standard W/D setup, but that isn't the point: a standard W/D setup isn't an option in an apartment without laundry hookups. Of course a 22V dryer is faster, but you know, my kitchen doesn't have a bunch of extra 220V outlet. If the combo needed 22V to dry, then I couldn't use the combo anyway.
