Hoover twinnies and tangling
I used a Hoover twin for a while. There is a technique to it.
Fill the tub with water first. no clothes, just water. Fill to the line above the pulsator. You can't fill less for small loads, always fill to the line.
Start the machine washing and add detergent. Now feed in the washing one item at a time. Put each item in near the pulsator and let the whirling water pull the item from your hands. Lightly loaded, the washing will whizz around really fast. As you add more washing, the clothes slow down in their spinning around the tub. There is a point where the load moves quickly for a bit, then slows down a bit, then speeds up as different items pass the pulsator. That is about the right size load. Also, mix up items. Don't try to do a whole load of jeans, they are too stiff and the load will stall. Wash an assortment of item sizes. Even slightly overloading and it will tangle. The load has to move freely and quickly. Items near the pulsator will always move quickly, items further away a bit slower but if there is too great a speed difference, things knot up.
My partner's uncle used a Hoover twin for many years, he was a widower and washed for two sons and himself. He told a workmate (a single man) about what a great machine they were and the friend bought one too. He reported back after the first weekend that he did a load on the Saturday, got so enthused about the great little washer that he went through the house looking for more things to wash. Eventually he took all his ties out of the wardrobe and washed a load of ties. They tangled into an impenetrable mess and had to be thrown away!
