iRobot used IFA 2026 in Berlin to unveil its most ambitious concept in years: the Roomba Duo, a dual-unit robot vacuum and mop system in which one robot physically carries and deploys a second robot. Announced on September 4, 2026, it is the company’s answer to a long-standing trade-off in floor care, and a clear statement that the Roomba inventor intends to fight back against Chinese rivals.
The idea is simple to describe and wild to watch: a tall main robot handles heavy-duty vacuuming and steam mopping across open floors, while a mechanical arm lowers an ultra-slim companion robot into the tight spaces the main unit cannot reach. No other consumer robot vacuum offers anything like it.
One System, Two Specialized Robots
The main robot has a cylindrical body that maximizes internal space for wet-dry cleaning hardware, including high-capacity water tanks, a powerful motor, and a large battery. It stands approximately 60 cm tall and weighs around 30 kg, carrying the companion unit on a top-mounted mechanical arm whose end stays level while moving to keep the smaller robot stable during transport.
The companion robot is based on the Roomba Plus 575 Combo that iRobot launched earlier in 2026. It measures just 8.35 cm tall and 29.8 cm wide, a profile slim enough to slide beneath beds, sofas, TV cabinets, and between dining chairs where larger robots cannot go.
Both units share a home map through the Roomba Home App and communicate in real time, using AI to divide cleaning tasks: the main unit covers large open areas while the companion handles edges, under-furniture zones, and narrow gaps.
Steam Mopping With Real Pressure
The main unit is designed for vacuuming, mopping, and tackling stubborn stains with steam. Its PowerSpin Max Roller Mop applies roughly 4.7 kg (about 10 pounds) of downward pressure to the floor, while an internal heating element generates steam intended to soften dried-on dirt before the roller washes and collects it.
During a demonstration at iRobot’s IFA booth, the robot passed over a pile of spaghetti, vacuumed the food remnants, and then mopped the soiled area. The company positioned the demo as an attempt to deliver cleaning performance closer to actual floor washing rather than simply dragging a damp cloth across surfaces.
The pair works with an autonomous mobile dock, so the system is designed to operate as one intelligent unit rather than two gadgets that happen to share an app.
Background: iRobot’s Comeback Attempt
The Duo arrives at a pivotal moment for iRobot. The company invented the robot vacuum category but has lost market relevance in recent years as Roborock, Dreame, and others outpaced it on hardware. iRobot is now owned by the Chinese robotics group Picea, and IFA 2026 was its chosen stage for a comeback.
The Duo was unveiled alongside two shipping products, the Roomba Max 875 Combo and Plus 678 Combo, which introduce iRobot’s SealForce vacuuming technology. The message is that iRobot is innovating on both the practical front (better carpet cleaning today) and the conceptual front (entirely new robot architectures for tomorrow).
Outlook
iRobot has not announced pricing or a ship date for the Roomba Duo, and it is best understood as a concept showcasing where the company thinks floor care is headed. The engineering challenges are obvious: a 30 kg main unit, a mechanical deployment arm, and coordinated two-robot navigation all add cost and complexity.
Still, the Duo reframes the debate. While rivals iterate on suction figures and mop designs, iRobot is asking whether the single-robot form factor itself is the limitation. Even if the Duo never ships as shown, expect its ideas, coordinated multi-robot cleaning, steam-first mopping, and ultra-slim companions, to influence the category in 2027.
