The iRobot Roomba Mini is a compact robot vacuum and mop made by iRobot, launched on March 10, 2026, priced at £379 in the UK and €399 in Europe, available via the iRobot official store. It is the smallest Roomba ever made, measuring just 24.5 cm in diameter and 9.2 cm tall — roughly half the volume of conventional models like the Roomba 105. After a debut in Japan where the black colourway sold out fast, the iRobot Roomba Mini has now landed in UK and European markets, and the case for a genuinely tiny robot vacuum is more compelling than it might first appear.
What Makes the iRobot Roomba Mini Different From Every Other Roomba
Size is the headline, but the engineering behind it is worth unpacking. At 9.6 inches across, the Roomba Mini slips under furniture and into corners that defeat larger robots. iRobot CEO Gary Cohen put it plainly: “Roomba Mini proves that small can be mighty. Designed to clean small, tight spaces better than larger robots, our mini, compact robot delivers full-strength cleaning power in a smaller form, so it reaches more of your home”. That is a marketing claim, but the hardware backs it up to a degree — the vacuum uses ClearView LiDAR for room mapping and obstacle avoidance, including the ability to detect people, furniture, and rugs during mopping mode, and it operates in complete darkness.
The dock is equally miniaturized. iRobot has shrunk its AutoEmpty dock to match, complete with AllergenLock bags that need replacing roughly every 90 days. That is a meaningful quality-of-life feature at this price point — self-emptying docks used to be reserved for premium models. The Roomba Mini also supports scheduling via the iRobot Home app, plus voice control through Alexa, Siri, and Google Assistant, with a manual button start for anyone who prefers to keep things simple.
iRobot Roomba Mini vs SwitchBot and the Compact Robot Vacuum Market
The source article positions the iRobot Roomba Mini as a direct challenger to SwitchBot in the compact robot vacuum space, and that framing makes sense. The compact robot vacuum segment has been dominated by budget-oriented brands targeting small apartments, and iRobot’s entry brings LiDAR navigation and a self-emptying dock to a size class that rarely sees either. SwitchBot has built a following on affordability and smart home integration, but iRobot’s ecosystem maturity and the inclusion of AllergenLock self-emptying technology represent a meaningful step up in convenience.
Within iRobot’s own lineup, the Roomba Mini punches above its size. Its suction rivals the mid-tier Roomba 505 series, which is a reasonable benchmark for a machine this compact. The comparison to the Roomba 600 series is less useful — that is an older baseline — but the directional point stands: this is not a toy vacuum squeezed into a small chassis. It is a capable cleaner that happens to be unusually portable. The Ecovacs Deebot T90 Pro Omni, which launched around the same period with its own mopping system, targets a different segment entirely — larger homes with more complex cleaning needs — making the Roomba Mini’s small-space focus a genuine differentiator rather than a compromise.
Where the iRobot Roomba Mini Falls Short
There are real trade-offs here, and glossing over them would do prospective buyers a disservice. The single-brush design — rather than a dual-brush system — is the most significant hardware limitation. On hard floors, this is unlikely to matter much. On carpet, particularly thicker pile, a single brush is a genuine disadvantage compared to robots that use counter-rotating brushes to agitate fibres. If your small apartment is carpeted throughout, the Roomba Mini’s case weakens considerably.
The mopping system also deserves scrutiny. The Roomba Mini uses single-use disposable mop pads placed over the suction inlet, similar in concept to the Braava Jet approach. The pads trap dirt and leave a citrus scent, which sounds pleasant, but the ongoing cost of disposable pads adds up — and the vacuum cannot mop and vacuum simultaneously. You pick one mode per run. For a machine marketed at busy urban apartment dwellers, that sequential approach is a friction point worth noting before purchase.
Availability is another issue for a global audience. The Roomba Mini launched first in Japan, then in the UK and Europe on March 10, 2026. There are no confirmed plans for a US, Australian, or North American release. If you are outside Europe or the UK, this product is currently not for you — and iRobot has not indicated when or whether that will change.
Is the iRobot Roomba Mini worth buying for small apartments?
For apartments in the 40 to 60 square metre range with mostly hard floors, the Roomba Mini makes a strong argument for itself. LiDAR navigation at this price is unusual in the compact segment, the self-emptying dock removes the most annoying maintenance task, and the four colour options — white, pink, mint, and black — mean it does not have to hide in a corner. It is genuinely designed to live in a small space rather than tolerate one.
Does the Roomba Mini work in the dark?
Yes. The ClearView LiDAR navigation system on the iRobot Roomba Mini is not dependent on visible light, so it maps and cleans effectively in complete darkness. This is a practical advantage for scheduling overnight cleaning runs without leaving lights on.
How often do you need to replace the AutoEmpty dock bags?
The AllergenLock bags in the Roomba Mini’s AutoEmpty dock need replacing approximately every 90 days under normal use. iRobot recommends keeping replacement bags on hand, as the dock will not self-empty once the bag is full.
The iRobot Roomba Mini is a genuinely interesting product that arrives at a moment when iRobot, now under Picea Robotics ownership, needed to prove it could still innovate. It does not replace a full-size robot vacuum for larger homes or carpeted spaces, but for the compact, hard-floor apartment market it is targeting, it is the most capable small robot vacuum iRobot has built — and one of the most thoughtfully engineered in its class. At £379 or €399, it asks for a premium over budget rivals, but the LiDAR navigation and self-emptying dock justify the gap for anyone who values convenience over upfront cost.
