A few years ago a co-worker bought a new F&P top loader. She was so excited, it was all we heard about until it was delivered; then the love affair was over. After the third one arrived, and didn't work either she bought a used Whirlpool dryer and has lived happily ever after.
Yes, how they work is you drop the clothes through a trap door at the top of the drum and then it snapps shut when the cycle starts. Problem(s) are. The drum has to be perfectly clear of anything to close properly. And the side to side air flow is different. and there isn't much tumble room, and it was noisy, and it took forever, and . . .Like I said she sent it back. I, however, didn't know that the top loader had been tried before.
