I had the experience of having a vacuum cleaner do that self propelled and I hated it....My electric lawn mower I bought with a very long cord and its a pain but a blessing to for I can run it as long as I want to without taking time to charge it and for my small lot it works just fine. But on a larger lot I might choose to go the battery route..These electric mowers cut very nice and they do not smell of gas nor do you have to take a trip to get the can of gas..I love my corded electric lawn mower and just need to be careful that I do not run over the cord. lol clancey
