Midea 50-pint Cube versions: gravity, pump and PE1 suffix

Model suffixes and drain plans

Three Midea 50-pint Cube pages, three different evidence situations

A white Cube image does not tell you whether the appliance has a lift pump, and a similar name does not prove that two suffixes share weight, hardware or setup. Compare the full model strings and the drain route documented for that exact version before choosing among the no-suffix MAD50S1QWT, pump MAD50PS1QWT-A and newer MAD50PE1QWT-S pages.

MAD50S1QWT: the documented gravity-first choice

Midea’s exact U.S. page identifies MAD50S1QWT as a 50-pint/day white Cube and lists no built-in pump. Its model-specific Cube manual supports bucket collection, continuous gravity drainage with the bucket installed and a separate bucketless-gravity arrangement. For bucketless operation, the manual requires the hose to slope down and not rise above the drain port; the mode must be enabled within three minutes of plugging in. This is the clearest fit among these three when the outlet is lower than the machine and a pump is unnecessary. The verified 41.54-pound dry weight is useful for handling decisions, but a filled bucket adds substantially more weight.

MAD50PS1QWT-A: choose it when a measured rise requires a pump

The exact U.S. pump page identifies MAD50PS1QWT-A and its manual documents up to 14 feet of vertical pump rise. The bucket must stay in place while pumping; pump mode cannot be combined with bucketless mode. It can still be used for bucket collection or lower gravity drainage when a pump is not needed. The precise outlet location and hose route still matter. A pump specification is not a guarantee that every horizontal run, kink or discharge location will work.

This is the better-supported choice of the three if your essential requirement is to lift water up to a sink or window, provided your measured vertical lift is within its published manual limit. It is also heavier and retains the bucket in pump mode. Do not assume that the presence of a pump makes emptying or maintenance disappear.

MAD50PE1QWT-S: newer SmartHome listing, unresolved pump field

Midea’s exact current U.S. page names MAD50PE1QWT-S in the page title, canonical path, structured product data and gallery filenames. The associated owner manual cover lists both MAD50PE1QWT-S and MAD50PE1QWT-B. The page presents a 50-pint/day capacity, SmartHome app control and the lift-and-twist Cube form; the manual includes bucket, gravity and bucketless-gravity instructions for the listed PE1QWT models.

There is an important source mismatch: the page’s full specification row says “Model Number MAD50PS1QWT-A,” which belongs to a different model identity. That same row says the pump is absent, but because the row names the wrong SKU, it is not safe evidence for PE1QWT-S pump hardware. The manual describes pump instructions for pump-equipped versions without saying whether this S suffix is one of them. Thus its exact listing is a 50-pint SmartHome Cube and its manual supports lower gravity and bucketless gravity, but a pump lift is not established. The same conflict makes the listed dimensions and weight unsuitable as hard-fit facts for this suffix.

Let the drain answer your first question

• Lower outlet, no special app need: start with the documented no-pump MAD50S1QWT. Its exact weight and gravity/bucketless plans are the clearest.
• Raised outlet: compare the exact MAD50PS1QWT-A pump model. Measure vertical rise and keep its bucket installed during pump use.
• SmartHome plus bucketless gravity: MAD50PE1QWT-S has the feature and manual evidence, but verify the suffix on the sale item and do not count it for an essential pump lift or strict weight/dimension cap without correction from Midea.

Check the label, not the shared Cube outline

The Cube’s nested body and white gallery appearance can conceal the most consequential distinction: the drain hardware. Check the complete model on the listing, shipping paperwork, carton and appliance label. The S1, PS1, PE1 and A suffixes are not decorative shorthand for one interchangeable machine. Exact U.S. reviews: MAD50S1QWT, MAD50PS1QWT-A and MAD50PE1QWT-S. Their pages support different facts; do not transfer a pump, weight or room-area claim across them.

For any of the three, rated daily capacity is not a guaranteed room result. Midea’s Cube manual gives an indoor residential temperature range of 41–95°F and requires airflow clearance around the unit. Clean the filter on schedule, inspect hose connections during setup and empty the bucket before nesting the appliance for storage.
