Product review (5 stars): I love this little thing.
I currently live in a second floor apartment. My joints and balance are screwy, so I walk with a cane so that when I fatigue I don't turn my knees or ankles. I cant carry large objects up and down the stairs very well or very consistently. Since theres no laundry in my apartment, Id also need a way to get laundry to and from my place to the laundromat.

Realistically this meant paying my brother to do laundry for me when it was convenient for him. He tries hard, but I couldn't exactly be sure Id have enough clean clothes to get me through if I had to travel. Id periodically end up having to do laundry in my bathtub, let the laundry drip dry inside of the shower curtains, and hang the laundry all over my place. While not a huge deal to have the laundry hanging around, sometimes for a week before being dry, its hard to do laundry by hand.

Then a little apartment washer came through my social media feed. While a little bit pricier than I typically spend on things, it was a small fraction of the cost of a full sized washer, and it had a spin dryer. I ended up talking to my payee person and had him arrange things so I could have enough spending money the next month to purchase one.

My model is a Panda Small Compact Portable Washing Machine (6-7lbs Capacity) with Spin Dryer.  Its more work than your typical washer but its a life saver. Here are the steps I follow:

Making sure that the drain hose is in the sink and the drain switch is set to wash, fill the tub with the fill hose. The fill hose attaches to the sink faucet on one end, and drapes into the wash bin in the other. The fill time is about 5 minutes?
Add a TINY amount of laundry soap. Im serious, it needs hardly any.
Close the lid and set the timer to the appropriate cycle length. The longest is 15 minutes, and I usually just set it to that to be certain, though it could be as low as three minutes for undergarments.
When the cycle is done, switch the drain switch to drain. This takes about 5 minutes. You can optionally wring the clothes or if you have only one garment in there (like I usually do) you can throw it in the spinner while the wash tub is draining.
Wipe down the wash tub, clean the lint trap and re-secure it, switch the drain switch to wash, and fill the tub again.
Close the lid and set the timer to the appropriate length of time for your rinse cycle. When its over, double check that there aren't suds. If there are youve added a little too much soap to the wash cycle and it will need another rinse. If so, repeat steps 4-6 until there aren't suds.
Drain the wash tub, and put a garment at a time, two max, in the spinner. It will spin out a lot of the water, so youll have something that is just damp and can be hung any where without worry. I have washing and spun something one day and been able to wear it the next.  The longest spin cycle is 5 minutes. Make sure that the load is balanced. If it is, after it is up to speed it will be very quiet. If it continues to shake, the load is unbalanced and you need to re-position it.
Hang the spun clothes on hangers someplace where it can dry. There will probably be lint involved, so if you are wearing them to work or other important places, invest in a lint roller?
It is a lot of steps, but its a thousand times better than hand washing everything and now that my laundry is caught up, I have less of a stressor. It also is helpful for autistic reasons. I can wear literally the same dress every other day and have it be clean, instead of buying two of the same dress on sale. I can wear exactly whichever of my clothes I want when I want.

If you have easy access to a regular washer/dryer, you probably won't understand the sheer relief I have right now. (You should probably keep with those if you have access to them- the amount of work involved can be overwhelming for people used to modern washer/dryers.) It is amazing.

small white panda washer next to my bathroom sink. It fits easily into the space and the drain hose points into the sink. The lids are closed and you can see the dials.

The down side is that I cant wash my blankets in it. Its not big enough for the spinner to fit the whole blankets. But it can handle individual sheets and all of my towels, and all of my dresses that can be washed in a washer. Another issue is that the drainage hose can seep a little, but its not enough to be a huge issue- I just have a towel there that I change out periodically and its fine, but buying a washer mat would also work.

You also need to keep a dish towel nearby to wipe down the lid and control panel in between tub fulls. I don't actually count this as a downside, but some people might. The reason is that the control panel needs to be kept dry.  I had a week where the spinner timer was on the fritz because it got wet, but as soon as it dried out it was as good as new.

I also run a whites or empty cycle with bleach once a week to keep it clean and mold free. I let them soak overnight in the bleach.

So thats the Panda washer. It has really helped me with my stress levels by making one major task less overwhelming and less unpredictable.
