Roomba j7/j8 vs standard robot vacuums: PrecisionVision avoids pet waste and cables

The j7 and j8 use an on-device camera to spot and steer around obstacles like phone chargers and dog poop, while standard vacuums will eat cables or smear waste across your floor. PrecisionVision runs locally for privacy and speed, making the j7/j8 worth the premium for anyone who doesn’t want to clean up a pet disaster.
