Quick Answer: “Roomba Combo” isn’t one product — as of 2026 it’s a family that spans roughly $169.99 to $1,399.99 across three overlapping naming schemes iRobot has never fully retired: the original letter-suffix line (Combo j9+), the standalone flagship Combo 10 Max, and a newer three-digit Plus/Max tier running Plus 415 → Plus 515 → Plus 575 → Plus 678 → Max 775 → Max 875. All of it vacuums and mops in one pass; the differences are suction, mop mechanism, whether the dock empties and washes itself, and whether it navigates with a camera or LiDAR. Below is what each tier actually gets you.
If you’ve searched “iRobot Roomba Combo” and landed on five different-looking product names, you’re not imagining the confusion — iRobot is genuinely running three naming generations side by side right now.
By the numbers
iRobot’s own combo shop lists ten distinct Combo models on sale simultaneously as of this writing, spanning a $169.99–$1,399.99 price range — an 8x spread within one product line, according to iRobot’s official product pages. The newest mid-tier model, the Plus 415 Combo, replaced the Plus 405 Combo with a chassis iRobot describes as 46% slimmer, letting it clean under furniture the outgoing model couldn’t reach.
The current lineup, tier by tier
| Model | Price (2026) | Navigation | Dock |
|---|---|---|---|
| Roomba 105 Combo (no dock) | ~$169.99 | Basic | None — empty and refill by hand |
| Roomba 105 Combo + AutoEmpty | ~$469.99 | Basic | Auto-empty, 75 days |
| Roomba 205 DustCompactor | ~$469.99 | Basic | Compacts debris, 60 days |
| Roomba Plus 415 Combo | ~$499.99 | ClearView LiDAR | AutoWash (empty + wash + dry) |
| Roomba Plus 515 Combo | ~$599.99 | ClearView LiDAR | AutoWash (empty + wash + dry) |
| Roomba Plus 575 Combo | ~$699.99 | ClearView LiDAR | AutoWash, 46% smaller base |
| Roomba Plus 678 Combo | Varies | LiDAR + PrecisionVision AI | AutoWash (empty + wash + dry) |
| Roomba Max 775 Combo | ~$799.99 | ClearView Pro LiDAR + AI | AutoWash, PowerSpin roller mop |
| Roomba Max 875 Combo | ~$1,299.99 | ClearView Pro LiDAR + AI | AutoWash, PowerSpin roller mop |
| Roomba Combo 10 Max | ~$1,399.99 list | Camera only (PrecisionVision, no LiDAR) | AutoWash (empty + wash + dry) |
- The Plus 415 through Max 875 all use ClearView (Pro) LiDAR plus PrecisionVision AI obstacle avoidance — a real upgrade over the camera-only Combo 10 Max's navigation.
- Every tier from Plus 415 up carries an AutoWash dock that empties its bin and washes and dries the mop pad automatically.
- Suction climbs with price: the entry Plus 415 is rated at 20,000 Pa; the Plus 515 steps up to 22,000 Pa, per iRobot's own listings.

Three naming schemes, still all on sale
This is the part that trips people up. iRobot has not fully retired any of its Combo naming generations, so all three are live at once in 2026:
- The letter-suffix line — models like the Combo j9+, still sold on iRobot’s own site, Amazon, and Best Buy as of this writing. This was the naming pattern iRobot used before the 2026 numeric refresh.
- The standalone flagship name — just Combo 10 Max, with no letter or Plus/Max prefix. It predates the numeric Max tier and, unusually, is still iRobot’s most expensive Combo at $1,399.99 list despite navigating with a camera instead of the newer models’ LiDAR — a tradeoff our full Combo 10 Max review breaks down in detail.
- The new three-digit Plus/Max scheme — Plus 415, Plus 515, Plus 575, Plus 678, Max 775, Max 875 — introduced as the going-forward replacement pattern. The Plus 415 has already replaced the Plus 405 we reviewed in August, and the Max 775/875 pair now sits above the Max 705 tier we covered at launch.
None of that is an accident of bad naming — it’s the normal result of a hardware company selling through a long product cycle without pulling older SKUs the moment a new one ships. The practical takeaway: if you’re comparing prices across sites, match the exact model number, not just the tier name, since “105 Combo” and “105 Combo + AutoEmpty” are $300 apart on four extra words.
Which one should you actually buy?
For most buyers weighing this whole family at once, the Plus 515 or Plus 575 hit the useful middle: AutoWash docks, real LiDAR, and 22,000+ Pa suction well under $700. Reach for a Max model only if you specifically want the PowerSpin roller mop’s edge-cleaning, and reach for the older Combo 10 Max only if you find it heavily discounted — our review found its vacuuming, not its now-dated camera navigation, is the reason to consider it at a markdown. Budget shoppers who don’t mind emptying a bin by hand can skip the AutoWash tier entirely with the base 105 Combo. For a side-by-side against iRobot’s non-mopping “Vac” models and full brand ranking, see our best Roomba guide; if you’re cross-shopping outside the iRobot ecosystem entirely, our Roomba vs. Roborock comparison covers the other side of that decision.
The bottom line
“Roomba Combo” now covers ten simultaneously-sold models across three separate naming conventions, running from a $169.99 no-dock base unit to a $1,399.99 camera-navigating flagship. The safest way to shop the lineup in 2026 is to ignore the marketing tier name and compare the exact model number, suction rating, and dock type side by side — not assume “Combo” alone tells you what you’re getting.
