5 Key Differences Between the Roomba j7+ and i3+

The j7+ uses a camera and PrecisionVision to identify and avoid pet poop, cords, and shoes. The i3+ navigates by bumping into things and hoping for the best.

The j-series sees obstacles; the i-series feels them. This is the fundamental divide in the Roomba lineup.

The i3+ will plow through a phone charger cord and get tangled or drag it across the room. The j7+ will see the cord and go around it.

If you have pets, kids, or leave things on the floor, the j-series is worth the upgrade. The obstacle avoidance hardware makes the vacuum truly autonomous.

The j7+ (and newer j9) avoids pet poop, cords, and shoes. The i3+ has no such feature.
