## Product: iRobot Roomba i7+
**Brand:** iRobot

The Roomba j7+ is the direct successor to the i7+ — same form factor, same Clean Base, same AllergenLock bags — but with three meaningful upgrades and one tradeoff. If you've already narrowed your shortlist to these two, the answer almost always comes down to whether you have pets, kids, or an unpredictable floor.

What's the same. Both robots use the same three-stage AeroForce cleaning system with dual rubber multi-surface extractors, share the same 1,800 Pa suction rating, both have a roughly 75-minute runtime on a single charge, both auto-recharge and resume mid-job, both use the same 0.4-liter onboard bin, both ship with an identical Clean Base Automatic Dirt Disposal tower and the same proprietary AllergenLock bag. App control, voice assistants (Alexa and Google), Imprint Smart Mapping, room-specific cleaning, no-go zones, multi-floor maps (up to 10), and Carpet Boost mode are all identical. On hardwood, low-pile carpet, and basic edge cleaning the two robots produce essentially the same single-pass result.

What the j7+ adds. First, PrecisionVision Navigation — a forward-facing camera trained on a much larger object dataset that lets the j7+ identify and physically steer around obstacles in real time: power cords, charging cables, shoes, socks, and most importantly solid pet waste. iRobot backs this with the "Pet Owner Official Promise" — if your j7+ runs over solid pet waste during the first year of ownership, they replace the robot. The i7+ does not have any of this. It detects bumps after contact, like every Roomba before the j-series. Second, the j7+ ships with the slimmer, redesigned Clean Base (about 40% smaller in footprint and a few inches shorter), which fits under more pieces of furniture. Third, the j7+ asks via the app whether to add new obstacles it sees to permanent Keep Out Zones — useful for cord nests under desks, pet bowls, or a kid's toy bin.

What the i7+ has going for it. Price. At launch the j7+ retailed at $799 versus the i7+ at $799, but as the i7+ is a model older it now routinely sells for $399–$499 (refurbished sometimes $349) versus the j7+'s typical $599–$699 street price. If you don't have pets or small kids, the obstacle avoidance is a feature you'll never trigger, and the i7+ delivers identical day-to-day cleaning for several hundred dollars less.

Short version. Pets, kids, or messy cord situations — j7+. Tidy home, hardwood-heavy floor plan, want the cheapest auto-empty Roomba — i7+.
