Portable Washer Recommendations?

We would like to buy a portable washer that is pretty small for doing laundry.

Also we like it to have wheels so we could move it around.

Does anyone here have a small washer thus portable one that they used that they can recommend?

I have a rigid plastic jug that previously held 20# of kitty litter and has two handles. I use it in my bathtub to wash any clothes that are pajama pants or smaller by agitating the clothes in cold water and a few tablespoons of laundry detergent and hydrogen peroxide as needed for organic stains.
I put the detergent in the jug and half fill it w/ water.
Add dirty clothes and put lid on tight.
Shake jug fifty times in each direction. If I’m trying to get a stain out or the clothes are particularly grubby, I’ll let them sit for an hour or so after this, then agitate fifty times in every direction again and rinse them out in cold water. I wring them well and hang them to dry on plastic clothes hangers. If I need something to dry more quickly I roll the item in a towel and twist it good a few times before hanging.
Sheets and towels go in the usual washing machine.

For a time we had a portable, I guess, Kenmore. We were living in an apartment and kept it in the kitchen. It came with castors so we could move it out of the way. There was something you screwed onto the faucet of the kitchen sink. There was a double hose (one for water from the tap and the other for used water from the machine) from the washer going to a thing that snapped onto the thing on the faucet. Just turn on the water to the temperature you wanted, plug in the electric, and you were good to go.
