First announced at IFA last year, Switchbot’s new humidifier uses cold evaporation and a 4.5-liter tank that you’ll never have to refill yourself — if you own the Switchbot S10 robot vacuum. The latter can automatically bring water to the humidifier when it’s running low.

The SwitchBot Mini Robot Vacuum K10 Plus Pro ($600) arrives today with better navigation, more suction power, quieter operation, and increased corner cleaning ability over the K10 Plus.
