The catch
AEOCKY Rhea-001
Far hotter and wetter conditions sit behind the 80-pint headline than behind the 24.5-pint certified rating.
Side by side
AEOCKY Rhea-001 vs Dreo 733S: At the same collected-water rate, Dreo’s larger tank cuts trips
Quick verdict
Rhea-001 comes out slightly ahead on certified capacity and efficiency. Dreo 733S counters with app control and a larger tank, which means fewer trips at the same collected-water rate.
Before you buy
Why, and what it costs you
About 11 percent is the gap in certified capacity
Under the listed test records, Rhea is ahead by 2.4 pints per day.
Where this comes from
24.5 minus 22.1 equals 2.4, and 2.4 divided by 22.1 times 100 equals 10.9 percent.
The catch
Dreo Dehumidifier 733S
Its 73-pint headline was set under hot, saturated conditions instead of the current federal test.
AEOCKY Rhea-001
- Why pick it
- Local controls with no phone account needed suit you.
- The higher certified water-removal and efficiency figures come first for you.
- The catch
- Far hotter and wetter conditions sit behind the 80-pint headline than behind the 24.5-pint certified rating.
Dreo Dehumidifier 733S
- Why pick it
- Remote schedules and humidity checks are what you want.
- You need a larger tank but do not want to step up to a 50-pint-class machine.
- The catch
- Its 73-pint headline was set under hot, saturated conditions instead of the current federal test.

In practice
Differences you will notice
About 11 percent is the gap in certified capacity
Under the listed test records, Rhea is ahead by 2.4 pints per day.
How we worked this out
24.5 minus 22.1 equals 2.4, and 2.4 divided by 22.1 times 100 equals 10.9 percent.
Dreo holds about 28 percent more water
Its tank advantage comes to 3.2 pints.
How we worked this out
1.85 minus 1.45 equals 0.4 US gallon. Multiplying by 8 gives 3.2 pints. 0.4 divided by 1.45 equals 27.6 percent.
Different models win on efficiency and on convenience
Dreo adds remote access, while Rhea needs about 5.9 percent less test energy per equal liter.
How we worked this out
1 minus 1.75 divided by 1.86 equals 5.9 percent when inverse IEF is used. Nothing is assumed about savings on a home electricity bill.
Option A
AEOCKY, RHEA-001 / RHEA-RCS25(Y)-N4-3-25
Rhea-001
A compressor dehumidifier in a narrow upright cabinet, with local controls, gravity drainage and a 24.5-pint certified rating.
- Best for
- Moderate moisture loads, provided local controls and a hose drain meet your needs
Facts we checked
- ENERGY STAR's figures are 24.5 pints per day and an integrated energy factor of 1.86 L/kWh.
- A 1.45-gallon tank and a 14.45 by 8.66 by 24.09 inch cabinet are what the exact Amazon listing specifies.
- Gravity drainage and humidity settings from 40 to 80 percent in 5-point steps are documented by the manufacturer.
Option B
Dreo, DR-HDH003S
Dehumidifier 733S
A generous seven-liter tank and tuning for quieter medium-room use define this newer compact smart model.
- Best for
- Medium rooms when you care about app control, low noise and tank size together
Facts we checked
- The current ENERGY STAR test result comes to about 22.1 pints per day and 1.75 L/kWh.
- Dreo's specifications give 163 CFM, sound as low as 42 dB and a seven-liter tank.
- R32 refrigerant is used, and Dreo app control is supported.
Spec by spec
Where they really differ
| Spec | AEOCKY Rhea-001 | Dreo Dehumidifier 733S | In practice |
|---|---|---|---|
| Certified capacity | 24.5 pints per day | About 22.1 pints per day | In practice the rated gap is 2.4 pints, whatever difference unrelated maximum headlines may suggest. |
| Integrated energy factor | 1.86 L/kWh | 1.75 L/kWh | Per unit of energy, Rhea removes more water under the certification test. |
| Tank | 1.45 gallons | 1.85 gallons | Dreo has room for 0.4 gallon more water. |
| Remote control | No Wi-Fi | Dreo app and voice support | Remote checks and schedules are possible with Dreo. |
| Humidity settings | 40 to 80 percent in 5-point steps | App and local humidity adjustment | Look at the exact target and mode, and do not assume the controls behave the same. |
Trade-offs
What each pick costs you
With AEOCKY Rhea-001
- Several smart alternatives have bigger tanks than its 1.45-gallon tank, and it lacks both Wi-Fi and a built-in pump.
With Dreo Dehumidifier 733S
- Drainage is by gravity, with no internal lift pump.
Change of plan
When the answer changes
The real constraint is an elevated drain
Neither model fits. Within its installation limits, Cube 50 with pump discharges condensate uphill.
Decision guide
How to decide
On certified capacity and efficiency, Rhea-001 holds a modest advantage. App control and a larger tank, meaning fewer trips at the same collected-water rate, are what Dreo 733S adds.
Skip the maximum-pint contest
Both the 80-pint and the 73-pint headlines come from hot, humid test conditions. In the certified records these models sit much closer together, at 24.5 and about 22.1 pints per day. That is where a like-for-like capacity discussion should begin.
Decide how you want to run the machine
Rhea is operated from its local panel and needs no app setup. With Dreo you can check humidity and schedules remotely. When the dehumidifier lives downstairs and you want to know when to go look at it, remote status can count for more than a modest difference in capacity.
Plan where the water goes
An internal lift pump is absent from both. The larger tank on Dreo gives more storage, yet both need emptying unless a downhill drain is available. Collected water is not moved by an app notification, and the notification will not catch every hose problem.
What this page can’t tell you
- Calculations come from published ratings and tank sizes, and no hands-on drying test was done. Actual collection falls with temperature and relative humidity.
- The tank-runtime examples assume steady output and a tank that can be filled completely. Shutoff level, cycling and real room conditions all change the result.
By the numbers
What the data shows
What we found across the dehumidifiers we compare, plus the checked facts behind each finding.
How many fit
Only 3 of the 31 models checked meet every need here: “The space I'm drying is a medium room or finished basement”, “Since it will run often, efficiency counts”, “I want to look at humidity on my phone”, and “A hose can run downhill to a drain in my setup”.
3 models fit, out of 31 checkedThe gap in numbers
AEOCKY Rhea-001 lists 24.5 pints/day for moisture removal under the current test, 11% more than the 22.1 pints/day on Dreo Dehumidifier 733S.

Show the facts and the math
How we countedThe count uses each product's current fit ratings for “The space I'm drying is a medium room or finished basement”, “Since it will run often, efficiency counts”, “I want to look at humidity on my phone”, and “A hose can run downhill to a drain in my setup”. A need with no documented match is not counted.
How we calculatedOnly figures stated as ENERGY STAR, Appendix X1 or official current-condition results count. When a current test figure exists, older hot-saturated labels are left out. For context, 9 of 31 models publish comparable figures.
