What customers like about iRobot Roomba i3+

  • Automatic dust emptying through the included Clean Base reduces routine maintenance.
  • Strong suction and deep-cleaning performance, especially useful for collecting pet hair.
  • Intelligent navigation cleans in orderly straight rows with back-and-forth movements.
  • Excellent value compared with other high-end models.
  • Supports voice commands and is easy to set up and control through the app.

What customers don't like about iRobot Roomba i3+

  • The self-emptying base is quite loud when it pulls dirt out of the robot.
  • It lacks advanced smart mapping with the option to define specific no-go zones.
  • The app cannot be used to select and clean individual rooms in a personalised way.
  • Basic camera-free navigation can occasionally lead to bumps against furniture.

Verdict

The iRobot Roomba i3+ is a mid-range robot vacuum featuring a 13.26-inch wide and 3.63-inch tall chassis, equipped with a 3-Stage Cleaning System that delivers 10X the power-lifting suction of the Roomba 600 series, dual multi-surface rubber brushes, and a high-efficiency filter trapping 99% of allergens. Its primary advantage is the included Clean Base Automatic Dirt Disposal tower (12.2 x 15.1 x 19 inches) that stores up to 60 days of debris, alongside floor-tracking sensors for efficient row-by-row navigation and a recharge-and-resume capability supporting its 75-minute battery life. However, notable drawbacks include its lack of an integrated optical camera which limits advanced navigation and multi-floor mapping, noisy operation reaching up to 74dB, and the recurring cost of proprietary disposal bags.
