iRobot Roomba Mini: World's Smallest Robot Vacuum Combines LiDAR Navigation with AutoEmpty Dock

iRobot has unveiled the Roomba Mini, claiming the title of world's smallest robot vacuum at just 24.5 cm (9.6 in) in diameter. The diminutive device, launched under new Chinese ownership by Picea Robotics, represents a significant departure from conventional robot vacuum design while maintaining core cleaning capabilities.

Compact Design for Tight Spaces

The Roomba Mini's reduced footprint makes it ideal for navigating between furniture legs and cleaning under low-clearance obstacles. At approximately 9.2 cm (3.6 in) tall, it matches the height of many competing models while its diameter is roughly half that of standard robot vacuums. This size reduction extends to the AutoEmpty Dock, which iRobot has downsized to minimize its footprint in small living spaces.

Performance Claims and Limitations

According to iRobot, the Mini generates up to 70 times more suction power than the older Roomba 600 series. However, this impressive claim comes with a notable trade-off: the Mini features only a single brush instead of iRobot's traditional dual-brush system. This design choice may impact cleaning effectiveness, particularly on carpets where the dual-brush configuration typically excels at agitating and lifting debris.

Hybrid Cleaning with Compromises

The Roomba Mini incorporates a mopping function that takes an unconventional approach. Rather than using an advanced self-cleaning roller system found in premium models, iRobot opted for single-use mop pads that attach over the suction inlet. This design means users must choose between vacuuming and mopping modes - the device cannot perform both simultaneously. While this approach simplifies the mechanism and reduces maintenance, it may limit cleaning efficiency for households that frequently require both functions.

Advanced Navigation in a Small Package

Despite its compact size, the Roomba Mini doesn't compromise on navigation technology. The device features a LiDAR (Light Detection and Ranging) scanner for precise mapping and obstacle avoidance. This advanced navigation system should enable efficient cleaning patterns and the ability to create virtual boundaries or no-go zones through the companion app.

Pricing and Availability

The iRobot Roomba Mini with AutoEmpty Dock is available immediately in European markets at €399 / £379. The package includes the robot vacuum, the compact AutoEmpty Dock, and comes in four color options: white, pink, mint, and black. The AutoEmpty Dock uses disposable dust bags that typically require replacement every 90 days, adding to the ongoing cost of ownership.

Target Market and Competition

The Roomba Mini appears designed for urban dwellers in small apartments where space is at a premium. Its combination of compact size, automatic dustbin emptying, and LiDAR navigation positions it against premium compact robot vacuums from competitors like Roborock, Ecovacs, and Dreame. The €399 price point places it in the mid-range segment, though the single-brush design and disposable mopping pads may make it less appealing to users prioritizing maximum cleaning performance over space savings.

The Roomba Mini represents an interesting evolution in robot vacuum design, prioritizing size reduction and space efficiency over some traditional performance features. Whether this trade-off proves worthwhile will likely depend on individual user needs and living situations.
