iRobot's Roomba Duo Debuts as a Vacuum-Within-A-Vacuum Concept at IFA 2026

iRobot unveiled the Roomba Duo at IFA 2026—a large base unit that can steam-clean floors and houses a smaller, disc-shaped companion robot stored in a top cavity that’s deployed for tight spots. The concept envisions a heavy-duty base for deep cleaning and longer runtime, with the companion bot essentially being a Roomba Plus 575. It’s a market-facing idea only in the concept stage, with no price or release date announced, and questions remain about whether steam cleaning will handle stubborn stains as hoped.
