Our verdict
This particular i8 listing ships with a basic Home Base rather than the auto-emptying Clean Base, so despite the HEPA filter and swappable vacuum/mop bin, it won't suit anyone buying specifically for hands-off, self-emptying convenience — check the box contents carefully before assuming otherwise. With suction power, runtime and noise levels all unpublished by iRobot, it's also a difficult one to judge against competitors on hard numbers alone.

Filtration and cleaning
The Combo i8 has a HEPA-rated filter, and an extra High-Efficiency Filter is included in the box as a spare. The dust bin is compact at 0.4L, which fits the "small-apartments" use case iRobot lists for this model but will need emptying more often in a larger, heavily-carpeted home. Suction power (in watts or Pa) and per-charge runtime are not published on iRobot's UK product page, so we can't state figures for either - treat any number you see elsewhere as until confirmed by the retailer.
Mopping: a bin-swap system, not simultaneous vacuum and mop
This is a combo model rather than a machine with separate water and dust tanks running side by side. You switch between vacuum-only and vacuum-and-mop modes by swapping the Interchangeable Roomba Combo Bin, using the included Microfibre Mopping Pad and Drip Tray for mopping runs.
Self-emptying dock: not included with this SKU
This is worth knowing before you buy: this configuration ships with a standard Home Base charging dock, not iRobot's auto-emptying Clean Base. So the Combo i8 as listed here does not empty its own bin - the Clean Base is a separate purchase if that's a feature you want.
Smart features and app control
The Combo i8 uses Imprint Smart Mapping and Dirt Detect Technology, runs on iRobot OS software, and is app-controlled with voice assistant compatibility (Alexa, Siri, Google Assistant).
Weight, size and warranty
At roughly 3.37kg, the Combo i8 sits in the "standard" weight band for robot vacuums. This figure, along with the 338 x 338 x 86mm dimensions reported by third-party listings, was not found on iRobot's official UK page and was converted from imperial units, so treat it as. The unit comes with a 2-year limited warranty.
Who this model suits
The Combo i8 fits multi-surface homes (carpet and hard floor) and smaller living spaces, based on iRobot's own use-case tagging, and its bin-swap mopping keeps the price down compared with models with a built-in auto-empty dock. If self-emptying, confirmed suction figures, or per-charge runtime are must-haves for you, check other iRobot vacuum cleaners or browse other robot vacuums to compare models with published performance data.
Does the iRobot Roomba Combo i8 empty itself automatically?
No. This SKU (I817840) comes with a basic Home Base charging dock rather than iRobot's auto-emptying Clean Base, which is sold separately, so the 0.4L dust bin needs to be emptied by hand after cleaning runs. This is worth checking carefully before buying, since other iRobot Combo listings do bundle the self-emptying Clean Base as standard. Skipping the auto-empty dock keeps this particular configuration's price down compared with bundles that include it. If hands-off bin emptying matters to you, factor in the extra cost of a separate Clean Base purchase, or compare other iRobot Combo models that include it out of the box.
What is the battery runtime of the Roomba Combo i8?
iRobot's UK product page does not publish a per-charge runtime figure for the Combo i8, so it cannot be confirmed here with the retailer if runtime is important to your decision. This gap sits alongside unpublished suction power and noise level figures for this exact SKU, meaning several specs shoppers commonly compare aren't available on iRobot's official listing. The robot does run on a Li-ion battery and uses Imprint Smart Mapping to navigate efficiently, which may offset some runtime concerns through smarter route planning rather than raw battery capacity. Buyers who need a confirmed runtime figure before purchasing should check directly with iRobot or a retailer rather than assume a figure from similar models in the range.
Does the Roomba Combo i8 have HEPA filtration?
Yes, the Roomba Combo i8 includes a HEPA-rated filter, plus a spare High-Efficiency Filter in the box, so you have a replacement ready without an immediate separate purchase. This filtration works within a compact 0.4L dust bin, which iRobot positions for the "small-apartments" use case, though it will need emptying more often in a larger or heavily-carpeted home. Since this particular SKU ships with a standard Home Base dock rather than the auto-emptying Clean Base, you'll be handling both filter and bin maintenance manually. With a 2-year warranty, HEPA filtration is one of the more clearly confirmed specs on this listing, unlike suction power and runtime, which iRobot hasn't published.
How much does the iRobot Roomba Combo i8 weigh?
The Roomba Combo i8 weighs around 3.37kg, based on third-party listings rather than the official UK page, so this figure should be treated as unconfirmed. That places it in the "standard" weight band for robot vacuums, alongside dimensions of roughly 338mm length by 86mm height reported by the same third-party sources, with width unconfirmed. This weight matters less for day-to-day use than for a robot vacuum, since it moves itself rather than being carried, though it's relevant if you're lifting it for bin emptying given this SKU's standard Home Base dock rather than a self-emptying one. Confirm exact dimensions with iRobot directly if fitting it under specific furniture is a concern.
What warranty comes with the iRobot Roomba Combo i8?
The iRobot Roomba Combo i8 comes with a 2-year limited warranty from iRobot, backing a machine with a HEPA-rated filter, a 0.4L dust bin and Imprint Smart Mapping navigation. That coverage applies regardless of the fact this particular SKU ships with a standard Home Base charging dock rather than the auto-emptying Clean Base, so the warranty covers the robot itself rather than a bundled self-emptying dock you'd need to buy separately. Given that suction power, runtime and precise weight aren't fully confirmed by iRobot's official UK page for this listing, the 2-year warranty is one of the more concrete, verifiable commitments available when deciding whether to buy.
