Key takeaways
- iRobot unveiled Roomba Duo at IFA 2026: a two robot floor care concept in which a roughly 66 pound main cleaner carries and deploys a slim companion for low furniture, edges, and narrow spaces.
- The main unit is designed for larger areas and tougher wet and dry messes, using vacuuming, controlled steam, a self cleaning roller mop, and hot air drying; the companion takes over where the larger machine cannot fit.
- At the same show, iRobot introduced the $1,199 Roomba Max 875 Combo and $899 Roomba Plus 678 Combo, both with an AutoWash Dock.

Roomba Duo is iRobot’s answer to a basic robot-vacuum trade-off: the hardware needed for intensive washing is bulky, while the best way to reach under furniture and into tight gaps is a low-profile robot. Unveiled at IFA 2026 in Berlin, the concept combines both approaches in one coordinated two-unit system. 3

Two specialized robots, one cleaning plan
The large main robot is built to vacuum and wash broad, open floor areas and tackle heavier wet-and-dry messes. It carries a much smaller companion robot in its body. When the main unit reaches an area it cannot enter, a top-mounted mechanical arm lowers the companion to the floor. The smaller robot can then clean beneath low furniture and work around edges, corners, and narrow spaces. 4

The two machines share a home map and are intended to coordinate tasks as a single system. iRobot’s premise is that assigning different jobs to differently shaped robots can avoid the compromises of trying to make one machine both powerful enough for deep washing and slim enough for every hard-to-reach area. 1

What the main Roomba Duo robot can do
The main unit is reported to weigh roughly 66 pounds and combines dry-debris pickup with steam-assisted floor washing. Its 60 mm PowerSpin Max Roller Mop is claimed to apply 46 newtons of downward force—about 4.7 kilograms-force. 6
Before the roller passes over the floor, an internal heater delivers controlled steam intended to loosen dried-on grime. The roller is designed to clean itself continuously while removing spills and loosened dirt, and a hot-air component dries the floor afterward. The main robot also vacuums dry debris such as crumbs and pet hair. 1
6
That hardware explains the larger chassis: the main unit is meant to bring greater washing capability and onboard capacity to open rooms, rather than squeeze all of that equipment into an ultra-slim robot.
Why the companion robot matters
A single heavy-duty floor washer can be effective in the middle of a room but still leave the places where dirt often accumulates: under beds, sofas, cabinets, and tables, plus along walls and in corners. Roomba Duo’s compact companion is intended to close that coverage gap after being mechanically deployed by the main unit. 4
6
The concept therefore treats navigation, mapping, cleaning assignments, and mobile-dock functions as shared infrastructure rather than as two separate products. The result is less a conventional robot vacuum with an accessory and more a coordinated cleaning team. 4

Is Roomba Duo coming to stores?
Not yet—and it may not. Roomba Duo was shown as a concept prototype at IFA, not announced as a retail model. iRobot did not provide a price or release date; its Japanese announcement states that sales are not planned. Reporting from the show also described the concept as a way to assess reaction to the two-robot design. 3

For buyers who want an available product rather than a concept, iRobot separately launched two conventional robot vacuum-and-mop models at IFA 2026: the Roomba Max 875 Combo for $1,199 and the Roomba Plus 678 Combo for $899. Both include an AutoWash Dock. 2
The practical takeaway
Roomba Duo is notable because it tries to solve a physical design problem with specialization rather than another incremental sensor or suction upgrade. The big robot handles forceful vacuuming and washing; the small one is built for clearance and coverage. Whether that architecture becomes a product will depend on iRobot’s next steps, but the IFA prototype makes the intended division of labor clear. 3
