As with my other tools, I use my air compressor to clean the mower well, but careful not to blow dirt from the underside into the motor. You can also use a damp cloth and a bucket of warm water (rinsing out the cloth and then squeezing out the excess water) to keep the outside looking nice. As long as you don't use anything like a hose or harsh spray that can make its way into the motor or electronics, you should be good.
All the best!
I use silicone spray to clean it, it looks like new and the plastic is easy to clean. My mower basically still looks new. Along with the fact it is electric, I have no worries about a gummed up carb from sitting all winter, or draining gas, buying expensive stabilizers. Buying into the EGO system has saved me a lot of time and in the long term, money and aggravation. I've compared them all, EGO is in my opinion, second to none with the products they carry.

I am way too much into the EGO brand right now... not good for my wallet...
Main problems with grass sticking occur with wet grass. In the summer in FL, it's a problem waiting for the dew to dry, before it gets too hot to mow, and before the frequent afternoon/evening thundershowers. We have humidity so thick here, you can almost swim through the air. Our daughter calls NFL/SGA the Tropic of Humidity.
Just don't hose down the under deck and cause rust or moisture to mess up the electronics!
I have had the mower for 1yr now, but my grass really sticks to the underside of the deck. Can I use silicone or some other coating to ease the regular clean up?
