Use the correct rated mode
Runtime can differ by floor-only, wall, intensive, or eco cycle. Record the rating tied to the mode you expect to use. Do not combine the longest runtime claim with the most demanding coverage mode unless documentation connects them.
Choose a reserve factor
For comparison, reduce the rated runtime by a transparent allowance rather than presenting the full claim as usable time. The allowance is a user-selected planning assumption for temperature, climbing, debris, route variation, and aging—not a measured product result.
Estimate required cycle time
Use a documented cycle length when available. If the cleaner offers several cycles, compare each separately. Pool size alone cannot generate an exact duration because speed, navigation, walls, and programmed behavior vary by model.
Interpret the margin
A larger ratio gives more planning room for demanding conditions. It does not prove complete coverage or better cleaning. Filtration, traction, route logic, and pool compatibility remain separate selection factors.
Revisit the estimate over time
Rechargeable batteries gradually lose capacity. Track whether cycles end earlier, follow storage and temperature guidance, and use authorized service options. Do not open or rebuild a sealed battery pack unless the manufacturer provides a qualified procedure.

Frequently asked questions
What reserve percentage should I use?
There is no universal value. Use a conservative assumption that you label clearly, then compare multiple scenarios. Manufacturer documentation and observed runtime for your pool are stronger inputs than a generic percentage.
Does runtime equal cleaning time?
Not always. Setup, self-parking behavior, cycle programming, and low-battery reserve can affect usable cleaning time. Check how the manufacturer defines its rating.
Can runtime predict square-foot coverage?
Not accurately without verified travel speed and route-efficiency data for the exact model and pool. Treat area conversions as rough scenarios, not factual coverage claims.
Final decision
Match the answer above to the exact model manual, pool measurements and maintenance routine. Amazon listings can change by seller, bundle and generation, so verify the product name and ASIN before relying on a feature.
