Earlier this year, we reviewed the SwitchBot S10, a vacuuming and wet mopping robot that uses a water-integrated docking system to autonomously manage both clean and dirty water for you. It’s a pretty clever solution, and we appreciated that SwitchBot was willing to try something a little different.

At CES this week, SwitchBot introduced the K20+ Pro, a little autonomous vacuum that can integrate with a bunch of different accessories by pulling them around on a backpack cart of sorts. The K20+ Pro is SwitchBot’s latest effort to explore what’s possible with mobile home robots.

What we’re looking at here is a “mini” robotic vacuum (it’s about 25 centimeters in diameter) that does everything a robotic vacuum does nowadays: It uses lidar to make a map of your house so that you can direct it where to go, it’s got a dock to empty itself and recharge, and so on. The mini robotic vacuum is attached to a wheeled platform that SwitchBot is calling a “FusionPlatform” that sits on top of the robot like a hat. The vacuum docks to this platform, and then the platform will go wherever the robot goes. This entire system (robot, dock, and platform) is the “K20+ Pro multitasking household robot.”

SwitchBot refers to the K20+ Pro as a “smart delivery assistant,” because you can put stuff on the FusionPlatform and the K20+ Pro will move that stuff around your house for you. This really doesn’t do it justice, though, because the platform is much more than just a passive mobile cart. It also can provide power to a bunch of different accessories, all of which benefit from autonomous mobility:
