The j7 sees charging cables and pet vomit — things most vacuums just eat

The Roomba j7 series has a front-facing camera and PrecisionVision object avoidance, and it genuinely changes what you can expect from an autonomous vacuum. Shoes, dog toys, charging cables — it identifies them and steers clear. Even pet vomit, which is about the worst thing a robot vacuum can encounter, gets flagged and avoided.

That last point is the real test. A vacuum that eats pet vomit doesn’t just ruin the vacuum — it spreads the mess across the entire floor. The j7’s ability to recognize and avoid biohazards is the feature that separates “I trust my vacuum to run while I’m out” from “I only run it when I can supervise.” If you have pets, the j7 series is the baseline, not the upgrade.
