Quick Answer: “Roomba Combo” isn’t one product. It is a family sold under three overlapping naming schemes: the letter-suffix line (Combo j9+), the standalone Combo 10 Max, and the three-digit Plus/Max tier: Plus 415 → Plus 515 → Plus 575 → Plus 678 → Max 775 → Max 875. On November 5, 2026, iRobot’s US store priced the current combos from $269.99 (105 Combo + AutoEmpty, on sale) to $1,199.99 (Max 875). The best value that day was the Plus 575 at $499.99: it has LiDAR plus the PrecisionVision AI camera and a dock that washes pads at 167°F, for less than the camera-free Plus 515 ($699.99).
Last updated: November 5, 2026. Prices re-checked on iRobot’s US store; several had changed by $100 to $300 since September.
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
- 7 combo models were listed on iRobot’s US Robot Vacuums + Mops shop page on November 5, 2026: the 105 Combo, Plus 415, Plus 515, Plus 575, Plus 678, Max 775 and Max 875.
- $269.99 to $1,199.99 was the price range on that page, a 4.4x spread within one product line.
- 3 of the 7 were on a limited-time sale: the 105 Combo (save $200), the Plus 415 (save $220) and the Plus 575 (save $300, ending November 7, 2026).
- 3.5x: the suction iRobot claims for the Plus 575 compared with the Plus 505 Combo. iRobot rates the Plus 515 at 3x and the Plus 678 at 4x the same baseline.
- 46%: how much slimmer by volume iRobot says the Plus 415 is than the Plus 405 it replaced. It makes the same 46% claim for the Plus 515 and Plus 575 against the Plus 505.

- Only the Plus 575 and up pair ClearView Pro LiDAR with the PrecisionVision AI obstacle camera. The Plus 415 and Plus 515 navigate with ClearView LiDAR alone.
- Every model from the Plus 415 up has an AutoWash dock that empties the bin and washes and dries the mop pads; the 515, 575, 678 and 875 also wash with hot water.
- iRobot's US pages rate suction as multiples rather than Pa: the Plus 415 has 2.8x the Plus 405, and the Plus 515, 575 and 678 have 3x, 3.5x and 4x the Plus 505.
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+, which predate the numeric refresh and are still sold through retailers. Our full Combo j9+ review covers its real-world pricing and the one gap (no self-washing mop pad) worth knowing before you buy.
- The standalone flagship name — just Combo 10 Max, with no letter or Plus/Max prefix. It predates the numeric Max tier, navigates with a camera instead of the newer models’ LiDAR, and no longer appears on iRobot’s US combo shop page. Our full Combo 10 Max review covers when a discounted unit still makes sense.
- The three-digit Plus/Max scheme — Plus 415, Plus 515, Plus 575, Plus 678, Max 775, Max 875 — the going-forward 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. The first wave of this scheme, the Plus 505 and its retail variant the Plus 507, is still sold, but the 507’s $999.99 list price is twice the Plus 575’s sale price.
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.
Which one should you actually buy?
For most buyers, the Plus 575 is the pick at its November 2026 price. At $499.99 it costs $200 less than the Plus 515 and adds the PrecisionVision AI camera, which the 515 lacks, while keeping the 167°F mop wash. Even at its $799.99 list price it undercuts the Plus 507 and the Max 775. Pick the Plus 415 ($379.99 on sale) if your floors are usually clear and you want the cheapest mop-washing dock. Step up to the Plus 678 or Max 875 only if you want a roller mop and SealForce carpet sealing; neither had published lab results in early November 2026. Budget shoppers who don’t mind rinsing a mop pad by hand can stop at the 105 Combo + AutoEmpty. 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” covers seven models on iRobot’s US combo shop page, from the $269.99 105 Combo + AutoEmpty to the $1,199.99 Max 875, plus older models such as the Combo j9+, Combo 10 Max and Plus 507 that are still sold elsewhere. Price no longer tracks the tier name: on November 5, 2026 the Plus 575 cost less than the Plus 515 and half as much as the Plus 507. Compare the exact model number, navigation (LiDAR only or LiDAR plus camera) and dock temperatures side by side, rather than assuming “Combo”, “Plus” or “Max” tells you what you’re getting.
