What is the best vacuum cleaning robot brand? The answer is simple! all of them are great! I personally have tried them all and own three different types. Although I should say that Bobsweep is the most heavy duty one. But maybe it is a little too serious about cleaning. I personally think the innovation is more about how fun these robotic vacuum cleaners are rather than how good vacuum robots can clean. I guess maybe there is also a point in cleaning too, as they are called vacuum cleaning robots! eh
