Pros and cons

Pros

The continuous-drain pipe can reduce the need to empty the tank manually when suitable drainage is available.
The 4.5-litre tank and auto shut-off are relevant for ordinary tank-based use.
Customer feedback reports effective moisture removal and laundry drying, although results will depend on room conditions.

Cons

The 4.5-litre tank is much smaller than the stated 20-litre daily extraction capacity, so tank-based operation may require emptying during sustained use.

What to know before buying

Listing details to confirm

The 20-litre daily extraction figure, 30-square-metre coverage and 345.00 power figure are listing claims rather than independently verified performance. The listed capacity and 4.5-litre tank refer to different measures. The 345.00 power value is shown without a unit, so its unit is unconfirmed.

What is the listed extraction capacity?

The listing gives a dehumidification capacity of 20 Liters per Day. This is a manufacturer claim, not an independently verified measurement.

How much water does the tank hold?

The stated tank volume is 4.5 Litres. A continuous-drain pipe is also listed as included.

What area is it intended to cover?

The listing states a floor area of 30 Square Meters. Treat this as the stated coverage claim rather than a guaranteed result for every room.

Is the power consumption specified?

The listing gives a wattage value of 345.00 but does not state a unit with that value. Confirm the rated power from the product label or manual before relying on it.
