iRobot’s September 2026 update is unusually important because it includes two real retail launches and one forward-looking concept. The Roomba Max 875 Combo and Roomba Plus 678 Combo are products shoppers can order now, while Roomba Duo is a prototype that shows where iRobot may take floor care next.

Keeping those statuses separate matters. The Max 875 and Plus 678 are buying decisions today. Duo is news and technology direction, not a product recommendation or purchase target.

Roomba Max 875 Combo Robot + AutoWash Dock

Availability: Available – launched September 2nd, 2026

Launch Price: $1,199.99

What makes it different

The Max 875 Combo is iRobot’s new flagship and the clearest statement of what the company considers its top hands-free cleaning package. It combines SealForce vacuuming with heated mopping and an AutoWash dock.

The appeal is system-level automation: vacuuming, mopping and dock maintenance are designed to work together rather than treating the robot as a vacuum with a basic wet pad attached.

Who should consider it

Shoppers who want the strongest current Roomba package and are comfortable paying flagship pricing for both vacuuming and mopping automation.

What to keep in mind

At $1,199.99, the Max 875 needs to justify its premium through features you will actually use. Buyers who mainly want current-generation combo cleaning should compare it closely with the Plus 678.

Roomba Plus 678 Combo Robot + AutoWash Dock

Availability: Available – launched September 2nd, 2026

Launch Price: $899.99

What makes it different

The Plus 678 brings much of iRobot’s new-generation combo concept down to a lower launch price. It still centers on vacuuming, mopping and dock automation, but it costs $300 less than the Max 875.

That price gap makes the Plus 678 especially important because it may be the more rational choice for buyers who want a current Roomba without paying for the top configuration simply because it is the flagship.

Who should consider it

Buyers who want a new Roomba with vacuuming, mopping and dock automation while staying below the Max 875’s four-figure price.

What to keep in mind

Do not assume the lower price automatically makes it the better buy. Compare the specific flagship features you care about before deciding.

Roomba Duo

Availability: No Date – prototype shown September 4th, 2026 at IFA

Launch Price: Not announced

What makes it different

Roomba Duo is a dual-unit concept built around a larger floor-washing robot carrying or deploying a smaller companion robot for lower-clearance areas. It is a very different idea from the normal one-robot-one-dock formula.

That makes Duo worth covering in a new-release hub because it signals where iRobot may take floor care next. But it should remain completely separate from the retail models: there is no announced price, preorder or consumer release date.

Who should consider it

No current buyer. This belongs in the article as a future-facing announcement, not as a recommendation or monetized product block.

What to keep in mind

Do not present Duo as coming soon unless iRobot later confirms a consumer launch. Prototype hardware can change substantially or never reach retail.

Which New Roomba Should You Choose?

For actual buyers, the decision is between the Max 875 and Plus 678. Roomba Duo belongs in the comparison only as a future-facing concept.

Model	Cleaning focus	Best reason to choose it	Main tradeoff
Roomba Max 875 Combo	Flagship robot vacuum, heated mopping and dock automation	Most complete current hands-free Roomba package	Four-figure launch price
Roomba Plus 678 Combo	Robot vacuum and mop with AutoWash dock at a lower price	Current-generation combo cleaning for $300 less than the flagship	Does not carry every Max 875 flagship feature
Roomba Duo	Dual-unit future floor-care concept	Shows iRobot experimenting with a two-robot architecture	Prototype only with no consumer release date or price

What Changed in iRobot / Roomba’s Fall 2026 Lineup

• iRobot now has a clearer premium and step-down combo structure in the Max 875 and Plus 678.

• Heated mopping and dock automation are central to the new retail story.

• Roomba Duo signals experimentation with multi-robot architectures, but it remains a prototype.

Buy Now or Wait?

The Max 875 and Plus 678 are real buying decisions today. Choose between them on budget and feature need, not on the assumption that the flagship must automatically be better for every home.

Roomba Duo should not affect a purchase decision unless you are willing to wait for a concept that may change substantially or never reach retail in its current form.

The Bottom Line

The new Roomba lineup is easier to evaluate when retail products and concept hardware are kept separate. The Max 875 is the premium buy-now option, the Plus 678 is the more approachable new combo, and Duo is simply a glimpse at what iRobot may build next.

For many buyers, the Plus 678 deserves the closest look because it keeps the new combo-and-dock direction while cutting $300 from the flagship launch price.
