A Brief Comparison Table

My Experience With Roomba i4 Vs i6

Back in January 2025, I was fed up with hauling my old vacuum around my home, a 1,200-square-foot space with hardwood floors and low-pile rugs, thanks to my dog and cat’s constant shedding. On January 14, I snagged the Roomba i4+ for $350, lured by the self-emptying feature, and it arrived by January 19.

The first run on January 24 showed the 10x suction (versus the 600 series) handling pet hair and dust like a champ, with Smart Mapping guiding it in orderly rows. By February 20, after 15 cleans, it missed some kitchen corners, but the self-emptying bin lasted 20 days, easing my morning routine.

Curious about the upgrade, I picked up the Roomba i6+ on March 10 for $550, drawn by the advanced navigation, and it showed up by March 15. The vSLAM tech mapped my home in one go on March 20, letting me set no-go zones around my cat’s food bowl and clean specific rooms via the app—a leap from the i4.

By April 20, after 12 uses, it nabbed more pet hair on rugs, though the 75-minute battery needed a recharge mid-clean on bigger days. On July 1, with 30 runs each, the i4+ stayed budget-friendly for my one-level home, while the i6+ rocked multi-room control during a party. By July 2, after 50 uses, the i6+ felt sturdier, but both handled my pet chaos well.

Living with a shedding dog, a cat that scatters kibble, and a toddler’s toys, I’ve tested these bots hard. The i4+ powered through a hair jam on May 5, while the i6+ dodged a sock pile on June 12 thanks to its sensors. I run them 5-7 times weekly, loving the i4+’s cost-effective ease and the i6+’s smart features.

The i4+’s single map worked for my layout, but the i6+’s 10-map storage would shine in a bigger house. Both beat my manual vacuum, but your choice hinges on space and control—let’s explore!
