iRobot Roomba Max 775 Combo review

I haven't used this robot. I'm working from Gizmodo's review, published September 27, 2026, and iRobot's own product page. The 6.8 is my opinion from those two.

One test is thin ground for a verdict, so keep that in mind.

On iRobot's US store it costs $699.99£799€529 with the AutoWash dock, checked November 13, 2026.

Where it sits

iRobot launched the Max 775 in summer 2026 with four other Roombas, per Vacuum Wars. Vacuum Wars calls the Max 875 the flagship of that batch, so the 775 sits one step below it. The Plus 678 and Plus 515 are the cheaper combos with a washing dock.

So you're paying for the middle. That only makes sense if the middle does something the cheaper ones don't.

The slow part

Gizmodo ran it through a 750 sq ft apartment, vacuuming and then mopping. It took about two and a half hours. The Roborock Qrevo 2 Pro did the same apartment in about two, with 40% battery left against the Roomba's 36%.

Half an hour doesn't sound like much. It is if the robot runs while you're home, because of the noise (more below).

Mapping was quick: about 11 minutes, per Gizmodo. The first vacuum pass after that took about 39 minutes and only covered part of each room. I'd plan on a few runs before trusting it with the whole place.

The battery is a 6000 mAh LFP pack, according to iRobot. Ending a 2.5-hour job with 36% left suggests it won't die mid-apartment in a space that size. iRobot doesn't print a run time, so that Gizmodo number is all I have.

The mop is the good news

This is a roller mop, which iRobot calls PowerSpin with PerfectEdge. Gizmodo says it left a streak-free shine on hard floors. It also did a ketchup test without much smearing, which is the kind of lab science I respect.

The dock washes that roller with hot water. iRobot's page says 165 °F (75 °C) in one place and 167 °F (75 °C) in another. Two degrees won't change your floors, but I'd like a product page to agree with itself. The dock is also rated for up to 3 months hands-free, per iRobot.

The annoying part

Gizmodo didn't publish a decibel figure. It did call the high-pitched whine annoying. That's a whine you'd hear for two and a half hours.

Then the smaller failures. The app lost connection on long runs. The robot got stuck under a child's bed. And it mopped a rug it should have skipped, which is the one mistake I'd least forgive in a mopping robot.

iRobot says its PrecisionVision AI recognizes cords, shoes and pet waste. Gizmodo's write-up doesn't contradict that. It just shows the robot still has blind spots that aren't on the list.

At 4.1 in tall, per iRobot, it won't fit under every low bed either. Measure yours.

Against the Max 875

The 875 ($1,199.99Not verified€699) is the model above it. Nobody has published a test of it yet, so check the gap between the two prices before you decide. If it's small, I'd lean to the flagship. If it's large, I wouldn't pay it blind.

Against the Plus 678

This is the one I'd actually compare. The Plus 678 ($899.99Not verifiedNot verified) is also a roller-mop combo in the same price band, and it adds SprayForce pre-treatment. If the 775's mop is the reason you're here, the 678 deserves a look first.

I'd skip the 775 if you vacuum more than you mop. A 2.5-hour run with a whine, as Gizmodo describes it, is a lot to sit through for mostly carpet.

What iRobot doesn't tell you

There's no suction rating in pascals on the product page. There's no run time either. For a robot at this price, I'd expect both. Without them, Gizmodo's single run is the only performance number I can point you to.
