Small, light but not useless lawn mower.

The front lawn here is at best 13'x10' and is now mainly moss  . Can anyone recommend a small hover mower just to waggle over it on a weekly basis. I have a push cylinder one I've used, it's light,  doesn't involve running extension leads for power but it's useless on the moss.

Most of what I seen available look like flat strimmers with plastic blades  and don't get very good reviews.
