Decide on drainage before comparing coverage claims
Choose a bucket, downhill gravity drain or pump around the drain location you actually have. The BLACK+DECKER pump option addresses a different setup from a gravity-drain arrangement; confirm the manual’s pump lift and hose requirements.
Compare extraction ratings on the same testing basis, and check the room temperature. The manufacturer floor-area claims in the table are estimates, not measured evidence that one unit will control every basement of that size.
