The Roomba i3 and i7 are both well-built robot vacuum cleaners with sophisticated aesthetics.
The Roomba i3 and i7 sport the same round design that has become synonymous to the iRobot’s brand of robot vacuum cleaners. On top, you’ll find a few physical buttons to manage the machine. These buttons are linked into the robovac’s body, minimizing issues of dust entering them. Meanwhile, most of the cleaning features are discreetly tucked underneath the Roombas.
The i3, however, comes with a silver, metallic finish whereas the i7 looks more premium, clad as it is in a charcoal gray top cover with a black plastic that surrounds the controls. Both brandish a wide black bumper that keeps the vacuum cleaners from damaging itself as well as any furniture it might accidentally hit.
