Pros

•Lightweight design makes it extremely easy to maneuver and push, even with one hand or for older users with limited strength.
•Selropelled feature is smooth and infinitely adjustable, significantly reducing physical effort during mowing.
•Powerful brushless motor handles thick and long grass well, producing a clean cut and even stripes on the lawn.

•Single lever height adjustment with seven cutting levels allows quick and easy changes to grass height.

Cons

•Struggles a bit with very wet or extremely tall grass, requiring multiple passes or slower mowing.
•The handle can feel a bit loose or less sturdy after adjustment, raising some concerns about lonerm durability.
•Best suited for smaller to mediuized yards; larger yards may require purchasing an additional battery for continuous mowing.
•Cannot mow grass very short in mossy or uneven areas effectively, limiting some cutting preferences.
•Battery and charger are somewhat bulky, which might feel cumbersome for some users.
•Recharge time, while reasonable, is still close to two hours if you don’t have an extra battery handy.

Bottom Line

The Kobalt 40-Volt Brushless 20-in Push Cordless Electric Lawn Mower is an excellent choice if you want a lightweight, easy-to-use electric mower with strong battery life and quiet operation. It’s especially great for smaller yards or users who value ease of maneuvering and low physical effort thanks to its smooth self-propel system. However, if your lawn tends to have very tall or wet grass, or if you have a large yard and want to avoid downtime, consider investing in an extra battery or exploring mowers with longer runtime. Overall, for those prioritizing convenience and moderate yard care, this mower delivers solid value and performance.
