Winnowl Verdict

Our product audit of the PowerSmart 80V MAX 21-Inch Brushless Self-Propelled Lawn Mower positions it at a LAGGING (69) Winnowl Index, where the price and capability sit at or above average. The Strong Value index combined with the 45 brand strength from PowerSmart and an Average Performance rating is a balanced purchase. The Battery Voltage of 80 V is above the 46.13 and means you should be able to power through tall fescue and overgrown weeds without the motor struggling or bogging down, while on the lower end the Total Run Time is below the class average and may mean you will likely be able to mow a typical front and back yard on one charge without having to stop to find a charger. We recommend staying with this purchase; it captures 18% better cost to Performance than the standard entry in this class.
