Keep the regional suffix
The same family name may cover different voltages, controls or reservoirs. Store the full model code with the reference link and the date you checked it.
Mark the unknowns
A blank value is more honest than a guessed figure. Separate manufacturer ratings from your measurements and record the units. US gallons and imperial gallons are not the same.
Read the conditions
Coverage, output, noise and runtime need context. Where the source does not give a measurement method, treat a small numeric difference cautiously. A shortlist should also include care access and local support.
