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 LAGGING (69) 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 forced to wait several hours for a recharge which effectively restricts your ability to finish large jobs in one day simply because that Charging Time of 180 mins sits 81% beyond the class average. Honestly, we’d suggest a hard pivot from this Brand Tax product; that 10% higher price tag results in 8% less hardware for your dollar than the class average, so you're really not getting much for the extra cash.

Honestly, compared to other options out there, this product's performance is 17% below the average and earns an Average 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 180 mins Charging Time means that you will likely be forced to wait several hours for a recharge which effectively restricts your ability to finish large jobs in one day is something you'll just have to deal with.
