Can You Wash An Electric Lawn Mower?

As previously mentioned, YES, you can. Here is the step-by-step guide to ensure safety when you clean your electric lawnmower with water:

Turn Off The Power.

Always turn off the power entirely from the electric lawn mower before you start cleaning it.

Disassemble the parts you will be cleaning.

Disassemble everything that can be detached, such as the blade, motor cover, back hatch, joints and connectors, or other attachments to avoid missing a spot during cleaning.


When you’re about to clean your electric lawnmower, it’s possible to wash it with a hose or power washer in a low-pressure setting. However, IT IS NOT ADVISABLE as water and electricity don’t mix very well. Always use a soapy cloth when cleaning your electric lawnmower-wring excess water and soap from the fabric to allow faster drying on your electric lawnmower. Please bring it to a nearby repair shop or do the repairs yourself once you see significant dents and damage.

Inspect for any damages

At the same time as cleaning your lawnmower, it’s also the best time to inspect any damages or loose bolts within your electric lawnmower. Check if your blades are sharp enough to cut grass, and if not, use a blade sharpener to bring back its cutting efficiency. Scan the parts if there are any damages or bruises that can affect the efficiency and lifespan of your electric lawnmower.

Clean the back hatch and blade area with a brush

Always make sure that you clean the underside of your electric lawnmower. That’s where the grass builds up, and if not taken care of, it can grow moulds that might make your work harsher than it was before. Use a brush to scrape off any stuck grass under the lawnmower, as this can become a pile that can affect the speed and power of your lawnmower blade.

Let it dry out

Finally, after a thorough cleaning session, give each part of your electric lawn mower some time to dry before you begin putting it back together.
