A bread machine is an appliance into which you put all ingredients,turn some knobs, wait a few hours and voila you have a loaf of bread. The machines deiyezooger mentioned are kneader/mixers which produce a dough which still has to rise, be shaped, and put into the oven.
LionessMom if you are interested in the 5 lb capacity machine because you want to take Chala with a Bracha, there is a way to accomplish that. I will leave the details to the CR “Rabbonim Wannabes”.
