Which is better for pet hair?

The Shark Detect Pro is the stronger pick: HEPA filtration, DirtDetect suction boosts and a 60-day self-empty base aimed at pet owners. The j7+ counters with PrecisionVision and the P.O.O.P. promise, which matter if pet waste is a risk.

Which handles clutter better?

The Roomba j7+. PrecisionVision recognizes cords, socks, shoes and pet waste and steers around them. The Shark relies on Detect and React sensors without listed camera object recognition.

Is the Shark worth the extra money?

At $159.99 versus $119.99, the Shark buys HEPA filtration, longer runtime and stronger suction boosts. Pay the difference only if allergies or pet hair matter more than obstacle avoidance.

Which lasts longer per charge?

The Shark, at about 120 minutes on normal power. iRobot does not publish a runtime figure for the j7+, and it is typically shorter than two hours.

Do both empty themselves?

Yes. The Shark uses a bagless 60-day HEPA base; the j7+ uses the Clean Base with enclosed bags, so you buy replacement bags.

Which is better on carpets?

The Shark lists carpet among supported surfaces and boosts suction on detected dirt. The j7+ uses dual multi-surface rubber brushes and an edge-sweeping brush, with 10x the suction of the Roomba 600 series.

Shark Detect Pro Self-Empty Robot Vacuum vs iRobot Roomba j7+

Buy the Roomba j7+ if obstacle avoidance matters most: it uses PrecisionVision to steer around cords, socks and pet waste, and its best new price is $119.99 at Woot as of November 7, 2026. Buy the Shark Detect Pro if you want stronger suction, a HEPA-sealed self-empty base and longer runtime, at $159.99 at its lowest recent price (October 30, 2026). The Shark is the better cleaner on paper; the Roomba is cheaper and smarter about clutter.
