iRobot’s dual‑robot vision unveiled at IFA 2026
During the IFA trade show in Berlin, iRobot used a live demo to illustrate its newest home‑cleaning concept – the Roomba Duo. Unlike the single‑unit vacuums that dominate the market, this system pairs a full‑size robot capable of both dry vacuuming and steam‑mopping with a miniature companion that can slip into the tightest gaps. The two units communicate via the Roomba Home app, share a single floor plan and return to a common docking station that washes, dries and empties them automatically.
"the most powerful vacuum we have ever made," said Adam Pope, iRobot’s senior vice‑president of product development, referring to the larger robot.
How the two robots work together
The primary robot is a cylindrical machine roughly the size of a traditional Roomba but packed with a wet‑and‑dry cleaning system, a high‑output motor and a larger battery than most current models. It can vacuum carpet and hard floors, then switch to a steam‑mop mode where a roller presses the mop head onto the floor with about 46 newtons (≈4.7 kg) of force. An internal heater produces a burst of steam that loosens stubborn grime before the roller scrubs it away. A hot‑air dryer follows, helping wooden floors dry quickly and reducing the risk of water damage.
Mounted on top of this robot is a small mechanical arm. The arm stays level as the robot moves, allowing it to pick up the secondary unit and place it where the larger robot cannot reach – for example, under a low‑profile sofa or behind a kitchen island. Once positioned, the companion robot takes over, using its slimmer chassis to glide beneath furniture and clean edges that would otherwise be missed.
The companion robot – a specialised sidekick
The secondary unit is based on the Roomba Plus 575 Combo, a model that iRobot launched earlier this year. At just 8.3 cm tall and 30 cm wide, it can navigate between dining chairs, under beds and through narrow doorways. Its mop pad extends to 31 mm, and an edge‑sweeping brush tackles corners and baseboards. Air‑lifted omni‑wheels give it the ability to climb thresholds up to 3.5 cm, meaning it can move from room to room without getting stuck on carpet edges.
Both robots rely on iRobot’s ClearView Pro dual‑line LiDAR and PrecisionVision AI to map the home, detect obstacles and plot efficient cleaning routes. The shared dock, dubbed AutoWash, not only recharges the units but also washes and dries the mop pads, handles dirty water and empties a large dust bag that is claimed to last for months before needing replacement.
What this means for UK shoppers
For consumers in the United Kingdom who are already looking at smart‑home ecosystems that tie into Android phones, the Duo could be an interesting addition. The Roomba Home app runs on Android and iOS, allowing users to start, pause or schedule cleaning from their smartphones – a feature that aligns well with contract‑deal seekers who often bundle devices with data plans.
If iRobot decides to bring the Duo to market, it will likely sit above the current premium Roomba i7+ and s9+ models, both of which already support mapping and automatic dirt disposal. The added steam‑mop capability could appeal to households with mixed flooring (tiles, laminate, hardwood) that struggle with traditional wet‑mopping. However, the dual‑robot approach may also push the price well beyond the £600‑£800 range of today’s top‑end Roombas, potentially limiting its appeal to budget‑conscious buyers.
Comparison with existing iRobot line‑up
| Feature | Roomba Duo (concept) | Roomba s9+ (2023) | Roomba i7+ (2022) |
|---|---|---|---|
| Vacuum power | Near‑upright strength (claimed) | Strong, 40 Pa suction | Strong, 40 Pa suction |
| Mop type | Steam‑mop with 46 N pressure | Dry‑mop attachment | Dry‑mop attachment |
| Mapping | Dual‑line LiDAR + AI | vSLAM + Imprint™ | vSLAM + Imprint™ |
| Companion robot | Yes, dedicated slim unit | No | No |
| Auto‑empty bag | Yes, shared dock | Yes, separate dock | Yes, separate dock |
| Estimated price | TBD (likely premium) | £749 (approx.) | £649 (approx.) |
The biggest differentiator is the second robot, which could dramatically improve coverage under low furniture – a common complaint among Roomba owners who find the main unit repeatedly misses those spots.
Potential hurdles and unanswered questions
- Price and availability – iRobot has not disclosed any cost or launch window. Given the added hardware (mechanical arm, second robot, larger dock), the retail price could be substantially higher than current flagship models.
- Reliability of the arm – Carrying a robot on a moving platform introduces mechanical complexity. Early adopters will be watching for durability issues, especially on carpeted floors where the arm must stay level.
- Maintenance – While the AutoWash dock handles mop cleaning and dust disposal, users will still need to replace the mop pads and possibly the water tank. The frequency of these tasks could affect the overall value proposition.
- Integration with smart home hubs – iRobot already supports Google Assistant and Amazon Alexa. A clear roadmap for deeper Android integration (e.g., Matter compatibility) would make the Duo more attractive to Android‑centric households.
Bottom line for the UK market
The Roomba Duo showcases a bold step forward in robotic cleaning, merging vacuum power, steam‑mopping and a dedicated under‑furniture robot into a single ecosystem. For tech‑savvy homeowners who already rely on Android devices to control smart appliances, the concept hints at a future where a single app can manage multiple cleaning agents across the whole house.
Until iRobot releases pricing, availability and a concrete launch date, the Duo remains a tantalising glimpse of what could become the next premium offering in the UK. If the company can keep the price competitive and prove the reliability of the dual‑robot system, it may well set a new benchmark for automated home care.
Keep an eye on iRobot’s announcements over the coming months – the next IFA or a dedicated UK launch event could bring more concrete details, including whether the Duo will be offered through carrier bundles or as a standalone purchase.
