Direct answer
Argendon pump vs gravity drain: which should you choose?
Choose a pump when condensate must travel uphill or to a drain that is not below the unit. Gravity drainage is simpler when a reliable lower drain is nearby.
What matters for buyers
For dehumidifiers, the practical decision usually comes back to four variables: square footage, severity of the moisture load, drainage route, and operating temperature. Use published specifications as a starting point and verify current details with the manufacturer.
