In detail: Princess Smart Air Cooler 358670, app control
The Princess 358670 stands out among evaporative air coolers with a feature its rivals lack: connectivity. On top of the on-unit display and included remote, it can be controlled via the free Princess Home app (iOS and Android) or by voice thanks to Siri compatibility, for remote switching or adjustment without getting up.
Under the hood, it sticks to the classic evaporative cooling principle: water poured into the 3-litre tank soaks a membrane that a built-in fan draws air through, with no compressor or refrigerant gas. The advertised airflow, up to 1566 m3/h, is the highest in our mini air cooler lineup, for a power draw of just 60 W. Three operating modes (normal, natural, night) and three speeds allow the intensity to be adjusted to the time of day, backed up by 75° oscillation to spread the air across the room.
The retractable 3-litre tank is more modest than the family-sized units in this lineup, meaning more frequent refills, but the unit ships with two freezable ice blocks to drop into the water for a temporary cooling boost during heat spikes. A small fragrance box also lets you add a few drops of essential oil to lightly scent the room. A timer programmable up to 24 hours prevents the unit being left on by mistake, a practical detail reinforced by the reminders and automations available from the app.
A tower design 97.5 cm tall with a 29 x 29 cm footprint, it moves around easily thanks to its pivoting castors. Its noise level of 62 dB sits around the average for this product category, more noticeable on the top speed. Like any evaporative cooler, its effectiveness depends on ambient humidity and cannot rival a compressor-based air conditioner, a trait shared across this entire product family.
For anyone who values the comfort of remote control and the ability to schedule cooling in advance, the Princess 358670 brings a practical dimension that few evaporative rivals offer at this price point.

Comparison
Two compact evaporative air coolers often come up together in comparisons: the connected Princess 358670 versus the more classic OneConcept MCH-2 V2 FreshLine, which has a notably larger tank. Here is how the two compare.
| Criterion | Princess 358670 | OneConcept MCH-2 V2 |
|---|---|---|
| Water tank | 3 litres, retractable | 8 litres, with cooling blocks |
| Airflow | Up to 1566 m3/h | 403 m3/h |
| Power consumption | 60 W | 65 W |
| Control | Display, remote, app, Siri | Control panel, no app |
| Timer | Up to 24h | Up to 2h |
| Weight | 4.35 kg | 6.7 kg |
In short, the OneConcept MCH-2 bets on a notably larger tank and cooling blocks for a stronger cooling effect, while the Princess 358670 stands out for its connectivity (app, voice control) and a much longer timer, at the cost of a smaller tank that needs refilling more often. The choice mostly comes down to how much weight you put on remote control versus tank runtime.
Our tester's verdict: Christophe Delpuech
The 358670's strong suit comes down to one word: connectivity. The Princess Home app lets you schedule routines, mute the beeps or turn off the display at night, a level of comfort no other cooler in our lineup offers. Siri voice control is a genuine plus for switching it on without leaving the sofa. The advertised airflow (1566 m3/h) is the highest of the bunch, noticeable at start-up on the top speed, though that comes with a bit more noise (62 dB). The 3-litre tank stays modest compared with the family-sized units in this lineup, meaning more frequent refills, even though the 2 included ice blocks help boost the cooling effect when needed. The tower shape (97.5 cm tall) takes up little floor space but is fairly tall. Once again, real-world effectiveness in humid air remains the main caveat for this product category, worth keeping in mind even for a model this well equipped electronically.
Frequently asked questions: Princess Smart Air Cooler 358670, app control
The free app (iOS and Android) connects to the unit over 2.4 GHz WiFi and lets you set modes, speeds and timer remotely, create schedules matching your routine, turn off the display or mute the beeps. Siri voice control is also available.
It's more modest than the family-sized units, meaning more frequent refills, especially on the top speed. The 2 included ice blocks help boost the cooling effect temporarily without using more water.
Its noise level is rated at 62 dB, around the average for this category of evaporative coolers, more noticeable on the top speed. Night mode reduces the sound intensity for bedroom use.
Yes, like most evaporative coolers, it can run as a plain fan with no water in the tank, although the evaporative cooling effect is then no longer active.
The Princess 358670 cools the air through water evaporation, with no compressor or refrigerant gas, for much lower power draw (60 W) but a more limited cooling effect than a portable air conditioner, especially in already humid air.
