Winnowl Verdict
Even though the RYOBI 20" RY40190 40-Volt Brushless Lithium-Ion Cordless Battery Self Propelled Lawn Mower just cleared our audit with a MEDIOCRE (66) Winnowl Index, that score is really a sign that you're paying for the name on the box more than the actual features you're getting. You’re looking at an Average Performance and Mediocre Value product here, but it’s coming from a company with Strong Brand Strength, so you're definitely paying a premium just for that name on the box. If you're looking at 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 simply because that Total Run Time of 45 minutes sits 15% below the class average. Honestly, we’d suggest a hard pivot from this Brand Tax product; that 9% higher price tag results in 6% less hardware for your dollar than the class average, so you're really not getting much for the extra cash.

Performance Rating
Average
In its class, this product's performance is 15% below the average and earns an Average Performance rating. It’s a bit of a mixed bag: the Warranty indicates you should feel confident that the manufacturer will stand behind the technology for the typical life of the mower, but you may find 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—so just make sure that's a trade-off you're okay with.
