Budget smart 20 L with app control
VonHaus 20L Smart Dehumidifier
Short answer: if you want a smart 20 L for less, the VonHaus gives you app control with Alexa and Google Home, a 4.5 L tank, a laundry mode and a hose in the box. The catch: it’s louder on paper, at 44 dB.

If you want a smart 20 L without paying for a big name, the VonHaus is worth a look. VonHaus rates it at up to 20 litres a day for rooms up to 30 m², with a 4.5 L tank, a drain hose in the box and a published power draw of 280 W. That wattage is handy, because it lets you work out roughly what it’ll cost you per hour at your unit rate.
It connects to the Tuya Smart Life app, so you can change settings, switch modes and check the humidity from your phone, or use Alexa or Google Home. There are three modes: Auto holds your chosen humidity, Laundry runs continuously for washing on an airer, and Sleep dims the display and lowers the noise. You also get a 24-hour timer, a child lock, four wheels and a colour-coded humidity light. Worth knowing: VonHaus says the app won’t tell you when the tank’s full.
Here’s the catch: VonHaus lists 44 dB, the loudest published figure of the 20 L machines we cover. In your lounge or utility room that’s unlikely to bother you. In your bedroom at night, it might, even with sleep mode on.
If you want a quieter smart 20 L, we’d compare it with the Duux Bora Smart 20L. If you want a bigger tank for heavy laundry weeks, the Pro Breeze 20L holds 5.5 litres. And if you want a published table showing what a 20 L pulls at 20 °C, we’d look at the MeacoDry Arete One 20L.
Published specification
Extraction figures and room sizes are what the maker claims, and they’re often measured at a warm, humid lab point. Your rooms in the UK are usually cooler, so that’s a lower real take. We haven’t run our own lab tests.

Common questions
Can you control the VonHaus 20L Smart from your phone?
Yes. It works with the Tuya Smart Life app, and with Alexa and Google Home.
How much does the VonHaus 20L cost to run?
VonHaus lists 280 W, so it uses about 0.28 kWh for every hour it runs. Multiply that by your unit rate to get your cost per hour.
Is the VonHaus 20L Smart quiet enough for a bedroom?
Maybe not if you’re a light sleeper. VonHaus lists 44 dB, and there’s a sleep mode, but quieter published figures exist.
