The Roomba i3+ is a Wi-Fi robot vacuum that empties itself into a sealed base, so you can go up to about two months without touching the bin. It cleans in neat rows using floor-tracking sensors rather than a camera, so it maps only lightly and cannot store named room maps like the j7 and s9 lines. Dual rubber brushes handle pet hair well and the three-stage system pulls debris from carpet and hard floors. Owners like the hands-off emptying and app control, but many report navigation quirks, getting stuck, and a loud, slow clean compared with lidar rivals.

Ratings are middling. Owners value the self-emptying base and pet-hair pickup, but many complain about navigation, getting stuck, and noise.
The Roomba i3+ (3550) is a Wi-Fi connected robot vacuum with Clean Base Automatic Dirt Disposal. It runs on iRobot OS, learns and maps your home room by room, and suggests cleaning schedules based on your routine. It cleans with a Premium 3-Stage Cleaning System that has 10X Power-Lifting Suction, compared to the Roomba 600 series cleaning system.
It navigates in neat rows using floor tracking sensors, and Reactive Sensor Technology helps it avoid getting stuck. Dual Multi-Surface Rubber Brushes resist tangling with pet hair. You can send it to clean a specific room on demand using Google Assistant or Amazon Alexa.
When the bin is full, the robot returns to the Clean Base, empties itself and resumes cleaning. The base holds enough debris for the vacuum to empty itself for up to 60 days. AllergenLock Bags capture and trap 99% of pollen and mold.
