Midea Cube Dehumidifier (MAD50PS1QWT-S) review

MAD50PS1QWT-S is a distinct Midea Cube model identity on the 2024 owner-manual cover and in a U.S./Canada efficiency-program record. That record reports 49.45 pints per day and an integrated energy factor of 1.9 L/kWh. It is useful evidence for an existing owner or someone checking a used label, but it is not enough to treat the suffix as interchangeable with the better-documented no-suffix pump model.

Manufacturer source: Midea’s 2024 Cube owner manual, which lists MAD50PS1QWT-S. Published performance record: Efficiency Vermont’s qualified-product record for the exact -S model.

Read the whole model number before comparing it

The final “-S” is not decorative. Midea’s manual includes MAD50PS1QWT-S in a family list, while the separate qualification record also spells out that exact model. Midea’s available individual product details for similarly named Cubes do not establish every -S feature. Do not copy the no-suffix MAD50PS1QWT or the -A or -B specifications onto an appliance whose label ends in -S. This distinction matters most if you need a specific pump, app function, cabinet size or accessory bundle.

The efficiency-program record gives a water-removal value of 49.45 pints per day under Appendix X1 and an IEF of 1.9 L/kWh. Treat these as standardized published values, not a promise that the unit will remove that much water in your room. The 49.45 figure is also below a strict 50.00-pint minimum, even though rounded Cube names and marketing language may use a 50-pint class. If a 50-pint/day threshold is essential, use the exact number documented for the specific model rather than rounding it up.

What the shared manual can—and cannot—tell you

The 2024 manual explicitly covers this suffix, but it is a family guide rather than a complete -S specification sheet. It describes bucket collection, ordinary continuous gravity drainage, and a separate bucketless gravity arrangement. For bucketless use, the hose must slope down rather than rise above the drain outlet, and the mode has to be enabled soon after plugging the unit in. Those options can help an owner whose drain is below the appliance or who wants to avoid carrying a full bucket.

The same guide describes a drain-pump setup only for “pump model” units. It explains that pump operation requires the machine to sit on its bucket, gives a 14-foot maximum vertical rise, and warns about keeping the bucket and pump filter maintained. But the shared manual does not provide a suffix-by-suffix pump table that establishes whether MAD50PS1QWT-S is one of those pump models. The letter P in a model string is not enough to fill that gap. If a raised outlet is essential, do not count this -S version as a confirmed pump choice; use a model whose own page and instructions explicitly confirm the pump configuration and limit.

Use the rating without assuming the missing details

The program record lists portable-dehumidifier classification, 49.45 pints per day, 1.9 L/kWh, U.S. and Canadian markets, and a 2024 market-availability date. It leaves connected capability blank. That blank does not prove the unit lacks an app, but it also cannot satisfy an app-control requirement. The family manual has general SmartHome connection instructions; it does not establish that every listed model has the required wireless hardware. For a shopper who needs remote control, require exact model evidence rather than assuming that another Cube’s app listing applies.

Likewise, the saved suffix-specific evidence does not establish this model’s dry weight, dimensions, bucket volume, noise, included hose, exact color or current retail availability. The program record labels December 31, 2025 as its purchase-by/delist date; that is a qualification-program date, not a manufacturer statement that every existing unit was recalled or unusable. Treat this page as a reference for identifying an -S unit and reading its published rating, not as a reason to buy it new today.

Who should keep this reference

An owner with MAD50PS1QWT-S on the nameplate can use the shared manual for the family’s normal bucket and downward-gravity setups, then check the appliance itself and its exact support instructions before relying on a model-specific accessory or connected feature. A used-equipment shopper can compare the 49.45-pint Appendix X1 rating with the actual moisture-removal need, but should not accept a rounded “50-pint” label as evidence of a strict 50.00-pint result. If pump lift or app access is non-negotiable, choose an exact configuration with those capabilities explicitly documented instead. Keep the suffix in the comparison: the manual’s family grouping does not make the -S, no-suffix, -A and -B model numbers one interchangeable product.
