iRobot Sells 10 Roombas; Roller Mops Start at the Plus 678

iRobot’s US store lists ten Roombas with a price: two that only vacuum, three Plus Combos with spinning pads that lift, three roller-mop robots from the Plus 678 up, and two cheaper Combos that drag a microfiber pad and avoid rugs. PrecisionVision AI, iRobot’s name for its obstacle recognition, is listed on five of them: the Plus 575, the Plus 678 and all three Max models.

Prices below are as irobot.com showed them on 20 October 2026, with the list price first and any sale beside it. Specs and claims are iRobot’s, from each robot’s own product page.

All from iRobot’s US pages on 20 October 2026. The Plus 678 page said “Will ship in approximately 2 weeks”; the others showed “In Stock”. The Roomba Combo 10 Max still has a product page, but it showed no price or availability, so it is not in the table.

How to read the names

Vac means vacuum only; Combo means it mops too. Beyond that, the numbers and the Plus and Max labels do not map neatly onto one feature. The Plus line runs from a spinning-pad robot with ClearView LiDAR (415) to a roller-mop robot with PrecisionVision AI (678). Every Max lists ClearView Pro LiDAR with PrecisionVision AI, and the two Max Combos use rollers.

The cheapest pair, the 105 Combo and 205 DustCompactor Combo, differ mainly in where the dirt goes. The 105 Combo comes with an AutoEmpty dock; the 205 has none and, iRobot says, compacts debris and holds it inside the robot for up to 60 days.

Mops: pad, spinning pads or roller

Rugs are the first thing the mop column decides. The 105 Combo and 205 list “Carpet Detect avoids mopping rugs”, and name no lift; the Plus 415’s feature list, in the same place, names “auto-pad lift”. From the Plus 415 up, every Combo lifts its mop when it detects carpet. On the roller models, the Max 775 also covers the roller and the Max 875 (affiliate link to Amazon, opens in a new tab) lowers a shield.

Above that, the split is spinning pads (Plus 415, 515, 575) against a roller rinsed as it turns (Plus 678 (affiliate link to Amazon, opens in a new tab), Max 775, Max 875). How robot mop types differ sets out what each mechanism asks of you, using makers’ figures across brands; here the point is only which Roomba has which.

Obstacles: what iRobot claims for each

All ten list LiDAR. The difference is what iRobot says they recognise. The 105 Vac’s page says ClearView LiDAR “avoids obstacles”, and the Plus 415’s that LiDAR and obstacle detection steer around “cords, shoes, and toys”. The Plus 575, Plus 678 and three Max pages add PrecisionVision AI: the Max 715 Vac and Max 775 Combo say it recognises pet waste, and the Max 875 says “300+ common objects”.

These are iRobot’s descriptions, not test results; a robot that recognises cords still has to recognise yours.

Suction claims use five different yardsticks

All ten Roomba pages state suction as a multiple of an older Roomba, and their footnotes name five different ones. Two “4x” claims on the same store are not the same claim.

Robot	iRobot’s suction claim	Compared with
105 Vac (affiliate link to Amazon, opens in a new tab), 105 Combo, 205	70X	Roomba 600 series
Plus 415 Combo	2.8x	Roomba Plus 405 Combo
Plus 515 Combo	3x	Roomba Plus 505 Combo
Plus 575 Combo	3.5x	Roomba Plus 505 Combo
Plus 678 Combo (affiliate link to Amazon, opens in a new tab)	4x	Roomba Plus 505 Combo
Max 715 Vac	4X	Roomba 105
Max 775 Combo	4X	Roomba 105 Combo
Max 875 Combo (affiliate link to Amazon, opens in a new tab)	5x	Roomba Plus 505 Combo

The Plus 515, 575, 678 and Max 875 share a yardstick, so within those four the order is 3x, 3.5x, 4x, 5x. The Max 715 and 775 are measured against the 105 robots, which are themselves measured against the 600 series, and iRobot gives no absolute figure, in pascals or air watts, that would let the two groups be joined.

Who each one suits, by the specs

• Hard floors stay dry, or someone else mops: the 105 Vac (affiliate link to Amazon, opens in a new tab) or Max 715 Vac; the 715 adds PrecisionVision and a 90-day dock rating.
• Light mopping with rugs you are happy to have skipped: the 105 Combo, or the 205 if you would rather not have a dock.
• Rugs and mopping in one run: from the Plus 415 up, where the mop lifts and the dock washes it.
• A roller mop: the Plus 678, Max 775 or Max 875.

Questions people ask

What is the difference between Roomba Combo and Vac?

A Vac only vacuums; a Combo vacuums and mops. iRobot’s US store lists two Vacs, the 105 Vac and the Max 715 Vac, and eight Combos. The cheapest Combos drag a microfiber pad and avoid rugs; the Plus Combos lift spinning pads, and the 678, 775 and 875 use a roller.

What is the difference between Roomba Plus and Max?

On iRobot’s current pages, the Max models (715 Vac, 775 Combo, 875 Combo) all list ClearView Pro LiDAR with PrecisionVision AI. The Plus range splits: the 415 and 515 list ClearView LiDAR, while the 575 and 678 add Pro LiDAR and PrecisionVision. The Plus 678 uses a roller mop like the Max Combos.

Which Roomba has a roller mop?

The Plus 678 Combo, the Max 775 Combo and the Max 875 Combo. All three lift the roller when they detect carpet: the 678 by 10 mm, while the 775 and 875 also cover or shield it. iRobot rates the 875’s roller at 300 rpm and 18 N of downward pressure.

Which Roomba avoids pet waste?

iRobot’s pages say PrecisionVision AI recognises pet waste on the Max 715 Vac and Max 775 Combo, and the Max 875’s page says it recognises more than 300 common objects. PrecisionVision is also named on the Plus 575 and Plus 678. The 105 models, 205, Plus 415 and Plus 515 list ClearView LiDAR.

Is the Roomba 205 self-emptying?

Not into a dock. iRobot says the 205 DustCompactor Combo compacts debris and keeps it inside the robot for up to 60 days. The 105 Vac and 105 Combo come with an AutoEmpty dock that iRobot rates for up to 75 days, and the Max 715 Vac’s for up to 90.

Can I compare Roomba suction numbers?

Not directly. Each multiple is against a different older Roomba: the 105’s 70X is against the 600 series, the Plus 678’s 4x against the Plus 505 Combo, and the Max 715 Vac’s 4X against the Roomba 105. iRobot gives no absolute suction figure on these pages.
