Easy to assemble, no unnecessary (for someone) control functions from the phone, easy to operate and maintain, polisher (not broken, no water container). Got pros: It is easy to manage when you have adapted and intuitively figured it out. In use for 1.5 months, I run every other day, or even every one, and always collects dust. It's convenient that he is also a floor polisher. Got cons: The cloth needs to be dampened frequently. Peeped, then you can spray from a spray bottle. The mounts of the platform for the rag seem flimsy, it's scary to snap off. There is no virtual wall.
