Samsung recently rolled out yet another robotic vacuum cleaner to make sure your home remains free from dust bunnies automatically – of course, we do wonder why this model sports a circular form factor since the square one would do much better as that kind can reach the corners of your home. Guess until the day where robotic vacuum cleaners are able to sprout their own hands and clean all the nooks and crannies of your home, you’d best be happy with a mediocre job or do it yourself. One good thing about the Samsung Tango Stealth is that it lives up to its namesake, emitting a mere 50db of noise when working.
