> the available robomowers all have tiny razor blades I was concerned about this as well when I deployed the first robot. After having a bunch of stumps removed from my yard, all my wires were messed up. So I actually switched to a big zero turn mower for about a year. You know what I found? The cut quality was worse, even with a sharp blade and perfectly leveled deck. The powerful traditional rotary mowers kick up a ton of dust, the wheels are much higher impact on the grass, and being a manual process it isn't practical to do every day or multiple times a week. We realized that we actually liked the "robot grass" much better, so at that point I fixed the wires and now the yard is better than ever. The reason the robot grass is much better is because it can cut much more frequently. I have them going daily in the AM and the yard is perpetually freshly mowed like a golf course. I just string trim about every other week. I'm not worried at all about the little blades (and we have a fairly rough yard being in a clearing on a mostly wooded lot on a hill). They recommend replacing them every month, but I get good results only changing them once a year.
