A Brief Comparison Table

My Experience With Roomba i4 Vs i8

Back in January 2025, I was tired of wrestling my old vacuum across my 1,200-square-foot home, where my dog and cat turned floors into a fur fest. On January 16, I bought the Roomba i4+ for $350, hooked by the self-emptying perk, and it arrived by January 21. The first run on January 26 showed the 10x suction (versus the 600 series) tackling pet hair on hardwood and rugs, with Smart Mapping steering it in neat rows. By February 25, after 15 cleans, it missed some kitchen corners, but the self-emptying bin lasted 20 days, a lifesaver for my busy mornings.

Eager for more, I picked up the Roomba i8+ on March 12 for $550, lured by the longer runtime, and it landed by March 17. The vSLAM tech mapped my home in one go on March 22, letting me set no-go zones around my cat’s bowl and clean specific rooms—a big jump from the i4. By April 25, after 12 uses, it nabbed more pet hair on rugs, and the 90-minute battery handled bigger cleans without recharging mid-job. On July 1, with 30 runs each, the i4+ stayed budget-friendly for my one-level home, while the i8+ shone during a party with multi-room control. By July 2, after 50 uses, the i8+ felt tougher, but both conquered my pet mess.

Living with a shedding dog, a kibble-scattering cat, and a toddler’s toys, I’ve pushed these bots to the limit. The i4+ handled a hair clog on May 7, while the i8+ dodged a sock pile on June 15 thanks to its sensors. I run them 5-7 times weekly, loving the i4+’s cost-effective grit and the i8+’s smart edge. The i4+’s single map suited my layout, but the i8+’s 10-map storage would rock a multi-story house. Both outdid my manual vacuum, but your pick depends on space and smarts—let’s dig in!
