A Brief Comparison Table

My Experience With Roomba i4 Vs j7

Back in January 2025, I was done wrestling my clunky vacuum across my 1,200-square-foot home, especially with my dog and cat turning it into a fur factory. On January 12, I picked up the Roomba i4+ for $350, excited about the self-emptying feature, and it arrived by January 17.

The 10x suction (versus the 600 series) handled my hardwood floors and low-pile rugs well during a test on January 22, with Smart Mapping steering it in orderly rows. By February 15, after 15 cleans, it grabbed most pet hair, though it missed some kitchen corners. The self-emptying bin lasted about 20 days, a game-changer for my busy mornings.

Eager for an upgrade, I snagged the Roomba j7+ on March 8 for $550, drawn by the obstacle avoidance hype, and it landed by March 13. The vSLAM tech mapped my place in one go on March 18, letting me set no-go zones around my cat’s food bowl—a feature the i4 lacks.

 By April 15, after 12 uses, it picked up more pet hair on rugs and dodged a toy my kid left out, though the 75-minute battery needed a recharge mid-clean on bigger days. On July 1, with 30 runs each, the i4+ kept costs low for my single-level home, while the j7+ excelled with multi-room control during a party. By July 2, after 50 uses, the j7+ felt more robust, but both tackled my pet mess like champs.

Living with a shedding dog, a curious cat, and a toddler’s toys, I’ve put these bots through hell. The i4+ handled a hair jam on May 3, while the j7+ avoided a sock pile on June 10 thanks to its camera.

 I run them 5-7 times weekly, loving the i4+’s budget-friendly reliability and the j7+’s smart navigation. The i4+’s single map sufficed for my layout, but the j7+’s 10-map storage would shine in a multi-story house. Both outclassed my manual vacuum, but your choice depends on space and smarts—let’s break it down!
