The brief

Analyst view

• Invented the robot vacuum market with Roomba in 2002; went public in 2005 at $3.56B valuation by 2021.
• 46% tariffs on Vietnam-made vacuums ($23M cost impact in 2025) and cheaper Chinese rivals led to bankruptcy.
• Picea Robotics acquired it on January 23, 2026. iRobot maintains US product development and marketing.

Technical approach

As reported

Navigation

Autonomous mapping and route planning

Uses SLAM to build a floor plan and optimize cleaning routes, avoiding obstacles and returning home to charge.

Vacuum design

Dual brushes

Two counter-rotating brushes sweep dirt toward the center; a side brush reaches walls and corners. Newer models add mopping and auto-empty docks.

AI-driven scheduling

Learning cleaning patterns

Roomba learns home layout and adjusts cleaning schedules based on usage patterns, room traffic, and pet activity (in Roomba Plus models).
