Lawn mulching via robot lawnmowers returns cuttings to the soil. What about feed’n’weed chemicals ??

I am thinking about buying a robot lawnmower because I am 80 yrs old and have angina. Normally I would scarify my lawn after applying a combined feed ‘n’ weed / moss killer, then REMOVE the clippings. I imagine that it would be unwise to use a robot or any mulching lawnmower until the feed ‘n ‘weed had been removed. Am I right ?

The cuttings put organic matter back into the soil. The fertilizer and herbicide will degrade in time as the grass cuttings decompose.

Mow at a high setting, about 3 inches, and mow weekly or often enough so you are not taking off more than about 1/3 of the blade at one time.
