iRobot Roomba Combo i5+ Robot Vacuum — Prices & Offers

Is there a current UK price for the Roomba Combo i5 Plus?

We don't have a tracked UK retailer price for the iRobot Roomba Combo i5 Plus in our current dataset. Rather than guess at a figure, this page explains what typically drives the price of a model in this class and what to look at once retailer prices become available on our site.

The short version: this is a mid-to-upper-tier robot vacuum and mop with an automatic dirt disposal dock, which puts it well above entry-level robot vacuums and above the plain Roomba i5 (vacuum-only, no auto-empty) on price. As soon as we have verified retailer offers for this exact model, they'll appear here alongside the price history.

What you're actually paying for

The iRobot Roomba Combo i5 Plus sits above a basic robot vacuum because of what comes in the box and what the machine does on its own:

• Clean Base Automatic Dirt Disposal — the dock empties the robot's bin automatically and is rated for around 60 days between manual emptying, which is the single biggest cost driver versus a robot that ships with just a charging stand.
• Combo (vacuum + mop) bin — a 0.276L interchangeable bin lets the same robot vacuum and mop without swapping the whole unit, adding mechanical complexity that basic vacuum-only models don't have.
• Imprint Smart Mapping — the robot builds and remembers a map of your home, which supports room-specific cleaning and no-go zones.
• Dirt Detect and the 4-Stage Cleaning system, paired with dual multi-surface rubber brushes and an edge-sweeping brush, which together are aimed at pulling in more debris on carpets and hard floors and reaching into corners.
• HEPA filtration, useful for households wanting finer dust and allergen capture from the exhaust air.
• A 1.8Ah lithium-ion battery giving up to 180 minutes of runtime per charge, and a working weight of 3.18kg.

Each of these adds cost over a bare-bones robot vacuum, and together they explain why models with an auto-empty dock and mopping function generally sit in a higher price bracket than single-function robot vacuums, even before you factor in brand and retailer margins.

Combo i5 Plus vs plain Roomba i5: why the price differs

It's easy to conflate this model with the plain Roomba i5, since the two names are close and — coincidentally — they share the same 3.18kg weight and 1.8Ah battery figures. Don't read anything into that overlap; they're genuinely different products at different price points, not a data discrepancy.

The plain Roomba i5 ships with a Home Base charging station only — no automatic dirt disposal and no mopping capability, just vacuuming. The Combo i5 Plus reviewed on this page adds the Clean Base Automatic Dirt Disposal dock and an interchangeable combo bin that lets it mop as well as vacuum. That extra dock and the mop hardware are the main reasons the Plus variant costs more than the standard i5, not a difference in motor power, weight, or battery capacity. If you're comparing the two on price, weigh whether hands-off bin emptying and mopping are worth the premium for your home, or whether the plain i5's simpler, cheaper setup covers your needs.

Where UK shoppers typically check for deals

Without a tracked offer for this specific model right now, the most useful thing we can do is point to the categories of retailer worth checking rather than name a specific price:

• Major UK electricals retailers — the large high-street and online electronics chains typically list current-generation iRobot models and run periodic sales events.
• iRobot's own UK store — manufacturer sites sometimes carry certified refurbished units or bundle offers not available elsewhere.
• General online marketplaces — useful for comparing multiple sellers, but check seller ratings and confirm the listing is for the Combo i5 Plus (with the Clean Base dock and mopping bin) rather than the plain i5 or a different Combo variant, since naming across the range is easy to mix up.

Once we have verified pricing for this model, it will be tracked and shown here rather than requiring you to cross-check listings manually. In the meantime, our comparison tool lets you weigh this model's specification against other robot vacuums and mops while you wait for pricing to firm up, and our other iRobot vacuum cleaners page covers where the rest of the current Roomba range sits on features.

What to check before you buy

When a price does appear for the Combo i5 Plus — here or elsewhere — a few checks are worth doing before you commit:

1. Confirm the exact model. "Combo i5 Plus" (mopping, auto-empty dock) is a different, more capable product than the plain "Roomba i5" (vacuum-only, basic charging stand) — make sure the listing matches the specification you actually want.
2. Check what's included. Confirm the Clean Base Automatic Dirt Disposal dock is part of the bundle, since some listings sell the robot alone.
3. Compare against the full specification. Our full iRobot Roomba Combo i5 Plus review covers the complete feature set, so you can judge whether a given price reflects genuine value for what the machine does.
4. Look beyond the headline price. Factor in replacement bin bags for the auto-empty dock, mop pads, and filters as ongoing costs, since these add up over the life of the machine.
5. Check for bundle or trade-in offers, which can sometimes bring the effective price down even when the sticker price looks similar across retailers.

If you're still deciding between this model and other robot vacuum-and-mop options, browsing other robot vacuum and mops side by side can help confirm whether the auto-empty and mopping combination here is worth prioritising for your home.
