Problems, parts and running costs

Summary

A 35-pint compressor dehumidifier whose upper unit nests inside its own bucket for storage, aimed at basements, medium rooms and closed garages. Check two things before you buy: 3,500 sq ft is Midea’s ceiling claim rather than a tested duty level, and there is no drain pump, so the hose only reaches a drain at or below the unit.

Strengths

  • Three independent labs have tested this exact model, and all three came back positive.
  • PCMag pulled a 900 sq ft basement from 75% to 50% RH in a little over three hours.
  • The body nests inside its own bucket at about half size, so storage is easy.
  • A 4.2-gallon tank means fewer trips to the sink, and fill presets let you carry less.
  • Replacement parts are well cataloged, including a humidity-sensor board at $7.95.
  • Instant full-tank push alerts, and app and Alexa commands respond quickly.

Weaknesses

  • No drain pump, so it cannot drain into a sink or a high-walled tub above the unit.
  • Noise is the weakest measured category, and RTINGS says it can still be noticeable to a light sleeper.
  • 35 pints is enough for medium rooms but not for a large open basement or an open-concept floor.
  • In 2026 owners report humidity sensors reading around 30–35% while separate meters show 55–60%.
  • The fan keeps running until the bucket is full, so noise outlasts the humidity target.
  • A full bucket comes to about 40.5 lb, and separating the top unit from the bucket takes strength.

How much water it pulls

RTINGS ran the exact MAD35S1QWT in its lab and scored it 7.6 for basements, 7.4 for large rooms, 7.2 for capacity and 7.0 for temperature stability. It measured 21.0 pints a day under its methodology and 393 W while operating, and it calls capacity “satisfactory”: enough for a larger bedroom or an office, not for open space.

PCMag put it at 4.0 and did the arithmetic in a real basement of a little more than 900 sq ft. Starting at 75% RH, the unit read 65% after 30 minutes and 58% after another 30, reaching a 50% target in a little over three hours, cross-checked against a separate thermostat in the same room. Consumer Reports rated it excellent and placed it second among 17 medium-capacity units.

The certified energy data belongs to the current “-A” revision, not to the base model: 35.82 pints a day and 378 kWh a year at an integrated energy factor of 2.01 L/kWh. Treat that as a ballpark for your power bill rather than a figure certified for the unit on the shelf. At the EIA’s July 2026 average residential rate of 18.31 cents/kWh, 378 kWh works out to about $69.21 a year (EIA, 2026). For scale, running at RTINGS’ measured 393 W for 12 hours a day would be about $315 a year, an intentionally conservative illustration rather than an expected bill.

Coverage, drainage and weight

Midea’s 3,500 sq ft rating is the top of its range, not a tested duty level. RTINGS’ own data contradicts it for open spaces: 35 pints limits how quickly it pulls moisture from a big open basement or an open-concept living area. A mid-size room, a finished basement under roughly 2,500 sq ft, or a closed garage sits inside what the testing supports. A large wet open basement is where you should size up instead.

Drainage is the other thing to check. There is no pump on this model, so the included hose needs a sink, floor drain or tub at or below the unit; RTINGS notes it can’t drain into a sink or high-walled tub otherwise. In bucketless mode the bucket comes off entirely and the unit sits over a floor drain.

Weight matters if you plan to empty it yourself. A full bucket comes to about 40.5 lb per Midea’s manual, and RTINGS flags the lift as a real problem for anyone with mobility issues. The fill presets (2.25, 3.0 and 3.75 gallons) let you trade tank capacity for a lighter carry. When it runs, the unit is 25.4 in tall, so it is compact only in storage.

Noise, sensors, parts and upkeep

Noise is this model’s weakest measured category, at 6.6 on RTINGS’ scale. In a larger space the sound fades into the background against a TV at normal volume or nearby conversation, but in a bedroom it stays moderate enough to notice if you’re a light sleeper. RTINGS measured 52.2 dBA on high and 50.4 on low; the 48 dBA figure in circulation comes from a dealer spec sheet. One design choice makes noise last longer: the fan doesn’t shut off at the humidity target, it runs until the bucket is full.

The 2026 reliability signal is the humidity sensor. In a July 2026 r/Dehumidifiers thread, several Cube owners reported brand-new units reading around 30–37% while separate hygrometers sat near 58–60%, and one was told to return the unit if the reading did not settle. A September 2026 r/Midea owner replaced the Smart Cube sensor and restored a believable mid-50s reading. Midea’s parts channel lists the compatible sensor as part 17120100000344 at $7.95. A low-reading humidistat can stop the compressor running in Set mode; Continuous mode is a workaround, not a fix. Nobody has published a failure rate, and the owner reports span several Cube sizes, so treat this as a known problem rather than a measured defect rate.

Other parts are cataloged: an air filter at $7.95 (part 12120100006533), a water tank at $72.95 (12120100006528), a main board at $52.95 (17120100004039), a fan at $11.95 (12100105001042) and a compressor at $102.95 (11103010023820). The filter is washable with a 250-hour reminder, so no filter is mandatory. Upkeep is what the manual describes: clean the air filter, keep the bucket properly seated, run the unit only between 41°F and 95°F, and fit the plastic cover on the drain hose outlet or it leaks. Separating the top unit from the bucket is the main physical service step. Warranty is 1 year.

Is it worth it?

At or below roughly $225 the sticker matches the evidence. Store checks in 2026 put it around $207 to $230 — Walmart at about $206.98, Consumer Reports offers from about $224.99, and Home Depot at $229.99. Above about $240, compare the 50-pint Cube models: Home Depot listed the MAD50S1QWT at $259.99 in 2026, and RTINGS recommends stepping up to 50-pint capacity when a 35-pint unit is too slow in large or open spaces.

Fit matters more than money here. If the drain sits above the unit, this is the wrong machine and you need a pump-equipped Midea model. If you are drying a large open wet basement, step up in capacity.

Durability evidence is thin and mostly adjacent. One owner describes cycling through three 50-pint units, each of which worked for a summer and then refused to restart in the spring; a Costco thread relays claims of a humidity sensor that doesn’t work and units that quit after about a year, and a 2026 thread describes a Cube freezing in its fourth season. Those are other Cube sizes or unnamed units. Wirecutter’s 2026 roundup recommends the 50-pint Cube and reports fewer problem reports for Midea dehumidifiers than for other major brands. Both are line-level signals, not evidence about this unit.

Which model this is

This page covers the white Midea Cube 35-pint, model MAD35S1QWT, UPC 810040942532. Several similar-looking Cube models are not this one: MAD35PS1QGR adds a built-in pump and a 6.25-gallon tank, MAD35S1WWT is a tall non-cube body, MAD35S1AWWT is the splash-guard bucket model, and MAD35C1AWS drops the smart control. The Canadian MC35 cubes are a separate line. A listing that pairs 35-pint capacity with a water pump is describing MAD35PS1QGR.

Two claims in circulation need correcting. This is ENERGY STAR Certified, not ENERGY STAR Most Efficient — ENERGY STAR’s record for the current version of the model family lists Most Efficient as No. And one Midea page bullet calls the Cube compact and good for up to 1,500 sq. ft.; that figure belongs to the 20-pint MAD20S1QWT, and the spec block on the same page says 3,500.

Whether the US unit currently shipping is still the R410A version or the HFC-32 “-A” revision is not established, and Midea’s published height is the nested height rather than the extended operating height.

The Amazon listing for this unit is ASIN B0GL7Q7173.
