Maybe, like their standup and push counterparts, you think all robot vacuums look essentially the same. They cary the same cylindrical shape, are very low to the ground and generally buzz quietly around a floor plan without much of a problem. If these are your initial thoughts, then you would be correct. However if you used these not so different characteristics to draw the conclusion that they are all equally good or band, then you would be wrong. Just like standing vacuums no two models are built exactly a like.
With all of the technology that goes into a self-propelled, self-guided vacuum, little differences can mean large degrees in variation of quality. This is a fact that a quick look at some robotic vacuum cleaner comparisons will c
