About this model

Nothing on the iRobot Roomba 104 2in1+ looks out for what lies in its path. Just A Dad Approved found that its front sensor serves docking alone, and gave it 1.5 out of 10 for avoiding obstacles on a list where 7.5 is ordinary. Cables, toys and anything low get driven over, which makes clearing the floor a chore before each outing.

What testers say about the iRobot Roomba 104 2in1+

Nothing on the iRobot Roomba 104 2in1+ looks out for what lies in its path. Just A Dad Approved found that its front sensor serves docking alone, and gave it 1.5 out of 10 for avoiding obstacles on a list where 7.5 is ordinary. Cables, toys and anything low get driven over, which makes clearing the floor a chore before each outing.

Mapping is a different matter. The lidar charted the tester's home quickly and accurately and kept working in the dark. Its mop is a pad dragged behind with no lift and no pressure, and with it clipped on the robot stays off carpet, so rugs go unvacuumed on a mopping run. Mopping scored 5.5, two points short of the lab's norm.

It is a small machine with a small station. The dock stands 11.5 inches high, 46 below what is usual among robots with a dust-only station, and tucks under a low shelf. The 240-milliliter bin is 65 short of the usual and the 120-minute runtime close to an hour under the 177.5 its peers get, so a flat is a better fit than a large house.

Where a row says “no (assumed)”, the maker's full product page for this model names the feature nowhere, so we take it as a no.
