Wyze has made its name in the US by offering competent smart home hardware for startlingly little money—$20 for a camera, $50 for a smart thermostat, and so on. The $250 Wyze Robot Vacuum is by far its most expensive product, but it's still cheap compared to the competition. This device sports full 3D mapping, scheduling, and it's got an app that isn't terrible. Most importantly, it does a very good job cleaning, assuming you don't mind a little noise. Unfortunately, you can't control this device with Google Assistant, but that's one of the few drawbacks.
Wyze has made a name for itself by selling smart home products at unusually-cheap prices, with varyingsuccess. The company started teasing a robot vacuum recently, and now the product is official. In typical Wyze fashion, it's also cheaper than most of its competitors.
