Midea Cube 50-Pint Dehumidifier with Pump review

The Midea MAD50PE1QWT-B is a 50-pint/day Cube with a built-in drain pump, a useful distinction if the only drain is above the appliance. Its pump can lift water up to 14 feet above the drain port, but the pump operates with the unit seated on its bucket; it is not a bucketless pump setup. ENERGY STAR lists this exact model at 49.67 pints/day under its test method, and its record conflicts with the product page’s SmartHome-app promise about connected capability.

Sources: Midea’s exact MAD50PE1QWT-B U.S. page, the Midea manual listing the PE1QWT-B and PE1QWT-S models, and the exact ENERGY STAR record.

Midea’s B-model page shows the white Cube body, bucket, handle and casters. The pump sits inside the bucket and is not visible in this exterior view; Midea does not label the art as a photograph or rendering.

Read the exact suffix and rating together

The B-model page heading, product number, UPC, description and specification table all identify MAD50PE1QWT-B. The Midea manual cover lists PE1QWT-B and PE1QWT-S together, and ENERGY STAR has a separate entry for the B suffix. This is not the older MAD50PS1QWT-B, nor the visually similar no-suffix MAD50PS1QWT. Their names and documentation should not be mixed just because each is a 50-pint Cube.

Midea’s page advertises a 50-pint/day class and an area claim up to 4,500 square feet. ENERGY STAR’s standardized record for this exact model reports 49.67 pints/day, an integrated energy factor of 2.01 L/kWh, and 515 kWh/year. Those are complementary descriptions: the first is the manufacturer’s rounded label, while the certification gives a standardized figure. Neither is a guarantee of daily water collection in every room. Temperature, humidity, airflow and continuing moisture entry affect what you collect; fix leaks and address the source of moisture separately.

The pump solves a specific drain-layout problem

For the PE1 family, the owner manual describes bucket collection, continuous gravity drainage with the bucket installed, bucketless gravity drainage, and a pump mode for pump models. Midea’s exact B page explicitly identifies a built-in pump, and the manual gives a maximum rise of 14 feet above the drain port. Measure vertical rise separately from the length of hose you need. That 14-foot ceiling is useful for an outlet above the unit, such as a nearby window, but it is not a claim about unlimited horizontal hose reach.

Pump mode keeps the unit seated on its bucket because the pump sits inside it. The pump does not begin until water reaches fill level four, and some water remains afterward to keep the pump inlet submerged. Midea advises emptying the bucket at least weekly while pumping and cleaning the pump filter. The manual also warns that the pump can be loud for its first three to five minutes and that an outdoor hose can freeze and stop drainage at or below 32°F. This is more involved than attaching a downhill gravity hose: there are two pump connections, a bucket, filter care and an outdoor-temperature limit to consider.

Do not combine pump and bucketless modes

If your drain is below the outlet, you can use continuous gravity drainage with the bucket installed. For a bucketless gravity setup, place the unit directly on a level floor, route the hose downward without raising it above the drain port, and enable bucketless mode within three minutes of plugging in. The manual says this mode disables the pump. A requirement for both bucketless placement and upward pumping is therefore incompatible with this model’s documented plans; the matching tool should reject that combination rather than combine two separate instructions.

The 2026 PE1-family fill-level table labels the highest setting 4.23 gallons; an earlier Midea Cube guide that also names the B and S suffixes lists 4.25 gallons. Treat the bucket as roughly 4.2 gallons rather than relying on that small revision difference. Capacity is not the empty-unit weight. Choose a lower fill level if a full bucket would be difficult to lift. The product page lists the empty unit at 41.54 pounds and gives dimensions of 14.45 inches wide, 14.57 deep and 14.76 high. The two-year warranty is a listed term, not a prediction of service life.

App support is not an essential-selection strength

Midea’s product page says users can control this model through SmartHome and voice assistants, and the manual includes wireless setup. However, the exact ENERGY STAR entry says “Connected Capable: No.” Because the product and certification disagree, this assessment does not treat app control as confirmed. If a network connection is essential, choose a model whose exact product record is consistent or get suffix-specific confirmation from Midea before buying. Ordinary controls remain available, so the connectivity uncertainty does not prevent use as a dehumidifier.

Who should shortlist the PE1QWT-B?

It is a plausible fit for a household wanting a 50-pint Cube with a documented pump and an uphill drain no higher than 14 feet, especially when the pump can remain seated in the bucket. It is less compelling if you can route gravity downhill, need the bucket removed during pumping, have a hard weight limit below 41.54 pounds, or require a verified app connection. The nested body and casters help with storage and moving the dry unit on a suitable floor, but do not erase the lift or bucket chores.

Compare this exact PE1QWT-B with the PE1QWT-S if upward drainage is not needed; the S page does not establish the same pump configuration. The older PS1QWT family has its own model-specific pump guide, but the “PE1” and “PS1” suffixes are not interchangeable. Check the complete model code on the listing and rating label. Do not choose solely from a 4,500-square-foot headline or a rounded pint number; first confirm the drainage route, temperature range, clearance and empty-bucket load your room can accommodate.
