As we all know, a home dehumidifier continuously generates condensate water from the dampness extracted from the humid air. This water needs to be disposed of by storing first in the internal tank and then emptying this tank manually.
Another option is to connect the unit to the drain point through the hosepipe. When you are opting for a drain hose connection, then it is better to have a system with an internal drain pump.
A dehumidifier with a pump has an additional feature that allows it to automatically drain the collected water to a nearby sink, drain, or outside. This eliminates the need to manually empty the water tank, which can be heavy and inconvenient.
Household dehumidifiers without a pump rely on gravity to drain the water through a hose, which means it has to be placed near a suitable outlet. Alternatively, the user can choose to use the water tank and empty it periodically. The choice between a dehumidification system with a pump or without depends on the user's preference, budget, and available space.
