The Roomba Duo is a floor-cleaning behemoth that can pull a tiny robovac from its hat — and it's iRobot's attempt at rejecting the 'spec wars' and trying 'something different, something new'

Robovac makers need their bots to be powerful, but also small enough to get into tight spots. The two things are often incompatible. </p><p>iRobot has come up with an imaginative solution. The iRobot Roomba Duo is a two-in-one bot in the truest sense. In its full form, it's a big, chunky floor cleaner, with a bulky body is large enough to contain everything you need for serious cleaning oomph. Then, in the upper part hides a regular robot vacuum that's compact enough to take care of detail work. </p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:2560px;"><p class="vanilla-image-block" style="padding-top:56.25%;"><img id="emnsd4NQCpyLdFriX3YaFF" name="20260904_155034 copy" alt="iRobot Roomba Duo robot vacuum being demoed at IFA" src="https://cdn.mos.cms.futurecdn.net/emnsd4NQCpyLdFriX3YaFF.jpg" mos="" align="middle" fullscreen="" width="2560" height="1440" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Future)</span></figcaption></figure><p>I spoke to Adam Pope, Chief Engineer & Vice President of Product Planning & Development at iRobot, to get some more insight into the unusual creation. </p><p>"The large base robot is really for heavy-duty cleaning," he tells me. "It's big enough to be able to have lots of water inside, and it can also have stronger vacuum. It's designed for heavy-duty cleaning and more open spaces and high-traffic areas in your home. You get that heavy-duty clean that you might use a stick vac or a wet-dry vac on today."</p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:2560px;"><p class="vanilla-image-block" style="padding-top:56.29%;"><img id="Lt3zGz5mALtQA4aDybFsmE" name="20260904_154827 copy" alt="iRobot Roomba Duo robot vacuum being demoed at IFA" src="https://cdn.mos.cms.futurecdn.net/Lt3zGz5mALtQA4aDybFsmE.jpg" mos="" align="middle" fullscreen="" width="2560" height="1441" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Future)</span></figcaption></figure><p>He explains that on top of all that, the base also deploys the companion bot — which is similar to the <a href="https://www.irobot.co.uk/en_GB/roomba-plus-575-series/575MASTER.html" target="_blank">Roomba Plus 575 robot</a>. That smaller robovac will clean under furniture, around chair legs, in corners and essentially "all those other spaces that the larger robot can't get to". </p><p>"They work together," he adds. "They each have their own job, and they kind of split the job up and go do those activities."</p><p>I saw a demo of the iRobot Roomba Duo in action at <a href="https://www.techradar.com/tag/ifa" target="_blank">IFA 2026</a>. The dock was lifted off the top of its cleaner base — like someone taking their hat off — and lowered gently to the ground, where the smaller robot vacuum exited. This then went on to successfully complete an obstacle course that looked far too tight for it to navigate, before returning to its hutch, to be lifted back to its charging home on top of the base bot. </p><figure role="gallery"><figure><img src="https://cdn.mos.cms.futurecdn.net/HiVuFmfukeAZAQT3z8cw3F.jpg" alt="iRobot Roomba Duo robot vacuum being demoed at IFA" /><figcaption><small role="credit">Future</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/ubbgdXpzaYuBQ4EazGxY9F.jpg" alt="iRobot Roomba Duo robot vacuum being demoed at IFA" /><figcaption><small role="credit">Future</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/BWJSfm5JXLdhKEpJvTSWsE.jpg" alt="iRobot Roomba Duo robot vacuum being demoed at IFA" /><figcaption><small role="credit">Future</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/Jz6tCgUHbCPREgfMCYS6yE.jpg" alt="iRobot Roomba Duo robot vacuum being demoed at IFA" /><figcaption><small role="credit">Future</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/5s427xcyAsf3fhBqZJGhxE.jpg" alt="iRobot Roomba Duo robot vacuum being demoed at IFA" /><figcaption><small role="credit">Future</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/6dogCcnq2PrHTgZwzjZPBE.jpg" alt="iRobot Roomba Duo robot vacuum being demoed at IFA" /><figcaption><small role="credit">Future</small></figcaption></figure><figure><img src="https://cdn.mos.cms.futurecdn.net/dqERL6HFDH2ruHUCkZwMzD.jpg" alt="iRobot Roomba Duo robot vacuum being demoed at IFA" /><figcaption><small role="credit">Future</small></figcaption></figure></figure><p>Unfortunately, for those who like the sound of this, the iRobot Duo isn't going on sale quite yet. "It's a cool little innovation concept we're just showing here at IFA to see how the market reacts to it and if there's interest in that type of product," Pope tells me. </p><p>I suggest it's quite difficult to stand out in the robot vacuum market these days, given the speed at which brands are releasing new models. "There's a lot of spec war in that category," he responds. "Not as much innovation as we'd like to see. So this was our way of trying to get something different, something new. But it still does the job — the job that customers actually need."</p> </article> ]]>
