Maintenance 2: Replace Worn Blades Regularly
The cutting blades are one of the few wear-and-tear components on a robot lawn mower and play a direct role in mowing quality. Sharp blades cut grass cleanly, helping maintain a healthier, better-looking lawn. As blades become dull or damaged, they begin to tear rather than cut the grass, leaving ragged edges that may turn brown or become more susceptible to disease.
For most homeowners, blades should be inspected regularly and replaced every 1–2 months during the mowing season. However, the exact replacement interval depends on factors such as lawn size, mowing frequency, grass type, and whether the blades have struck stones, branches, or other hard objects.
Signs It's Time to Replace the Blades
Replace the blades if you notice any of the following:
- Grass tips appear torn or uneven after mowing
- The mower leaves an inconsistent cutting finish
- The blades are chipped, bent, or visibly worn
