Class Audit Methodology

Winnowl Standard Specs (Calculated)

Specification
Formula
Class Audit Notes
WS - Runtime (minutes)
Formula (Usable Energy Capacity (Wh) / 560) * 60
Audit Note

Robotic mowers operate on a continuous maintenance model, taking micro-cuts rather than tackling overgrown grass. Winnowl calculates robotic runtime using a continuous 90-Watt operational load—reflecting real-world navigation, drive-wheel traction, and low-resistance blade rotation per docking cycle.

WS - Usable Energy Capacity (Wh)
Formula Battery Voltage (V) * Total Capacity (Ah) * 0.90
Audit Note

Battery storage in robotic mowers reflects total operational reserve (Voltage × Amp-Hours). Unlike traditional mowers that drain batteries in rapid high-draw bursts, robotic batteries undergo frequent, shallow charge cycles. We apply a 10% capacity deduction to account for docking reserve thresholds, battery management cutoffs, and conversion losses.

Manufacturer Stated Specs

Specification
Class Audit Notes
MFR - Maximum Lawn Area (sq ft)
Audit Note

Maximum lawn area receives zero weight in the primary scoring model because manufacturer square-footage claims assume a perfectly flat, unobstructed rectangle running 24/7. In real yards with slopes, narrow passages, trees, and complex perimeter wiring, actual coverage drops significantly. Because factory yard-size ratings lack a standardized boundary testing model, relying on them creates a high risk of undersizing the unit for your property.

MFR - Runtime (minutes)
Audit Note

Stated runtime gets zero weight in the primary index because factory specs vary wildly in how they account for docking idle time, edge-trimming passes, and obstacle navigation. Robotic mowers operate on continuous, low-draw maintenance cycles rather than high-power cleanup passes, making unverified brand runtime claims unreliable for direct comparison.

MFR - Single Battery Capacity (Ah)
Audit Note

Single battery capacity is excluded from scoring because robotic mower architecture prioritizes continuous charge-and-resume cycles over massive single-pack storage. Battery size is already factored into Usable Energy Capacity, rendering a standalone pack metric redundant.

MFR - Total Capacity (Ah)
Audit Note

Total pack capacity receives zero independent weight because raw amp-hours do not account for system voltage or docking frequency. Total capacity is already integrated into Usable Energy Capacity, which properly evaluates the actual energy reserve available between automatic recharges.
