DREO 711S: problems, parts and running costs
Checked: 2026-10-17
Summary
The 711S is a 110-pint smart dehumidifier for spaces up to 4,500 sq ft, with app and voice control, a 2-gallon tank and a drain hose in the box. The usual complaints are that the 110-pint rating assumes 86°F and 90% humidity, there is no built-in pump, the full tank is awkward to carry, and the unit is not a sleep-mode bedroom pick. Running costs are electricity plus occasional filter replacements, and it is a good buy at or below about $220.
Common problems and fixes
- No built-in pump — continuous drainage relies on gravity, so the included hose needs a downhill run to a floor drain. [2]
- Full tank is awkward — the 2-gallon tank is large for the class but awkward to carry when full, and the water level is hard to judge between empties. [2]
- Heat and noise — the unit gives off noticeable heat in warm rooms and OneSmartCrib says it is not a sleep-mode bedroom pick; the 46 dB figure is a manufacturer claim with no independent measurement. [1][2]
- No instrumented test — no established outlet has tested this exact model, so the capacity, noise and efficiency figures stay unverified, and Good Housekeeping’s 2026 lab testing did not include it among its top picks. [5]
- Warranty terms unknown — DREO’s warranty pages were rate-limited during research, so length and terms are unconfirmed. [4]
Parts and consumables
- Air filter — replacement pricing and availability were not published during research; DREO lists electricity and occasional filter replacements as the recurring costs. [4]
Yearly running cost
Electricity is the main recurring cost. The manufacturer claims up to 4 pints/kWh, above the ENERGY STAR 2024 level of 3.8 pints/kWh, but power draw in watts is not published, so a yearly figure cannot be computed. Add occasional filter replacements, for which DREO publishes no price. [4]
When it is a good buy
At $215.99 from dreo-shop.com, 40% off the $359.99 MSRP on dreo.com, the 711S is a strong-value buy for large-space dehumidification with smart features. OneSmartCrib listed it at $299.95 in June 2026, which is fair value; above $300 it is weak value unless the Dreo app ecosystem is the reason for buying. Frigidaire, GE and Midea are the alternatives with deeper test coverage and known reliability records. [1][2][3][5]
