Winnowl Verdict

The RYOBI 20" RY40190 40-Volt Brushless Lithium-Ion Cordless Battery Self Propelled Lawn Mower just cleared our audit with a MEDIOCRE (52) Winnowl Index—a score that unfortunately reflects more "brand" than "benefit." This is a Mediocre Performance and Mediocre Value product from a brand with Strong Brand Strength. With the RYOBI 20" RY40190 40-Volt Brushless Lithium-Ion Cordless Battery Self Propelled Lawn Mower with 5.0 Ah Battery and Charger Included, the specs show that you will likely be able to mow a typical front and back yard on one charge without having to stop to find a charger due to Total Run Time of 45 minutes, which sits 15% below the average. We recommend a hard pivot from this Brand Tax product; the 9% higher price tag results in 35% less hardware for your dollar than the class average.

Honestly, compared to other options out there, this product's performance is 37% below the average and earns a Mediocre Performance rating. While the Warranty indicates you should feel confident that the manufacturer will stand behind the technology for the typical life of the mower, the big catch is that the 45 minutes Total Run Time means that you will likely be able to mow a typical front and back yard on one charge without having to stop to find a charger is something you'll just have to deal with.
