iRobot Roomba Max 775: Specs, Features, Pros & Cons
This is iRobot's answer to a question its customers had been asking for two years: when would a Roomba get the roller-mop-and-station treatment the Chinese flagships made standard?
This is that machine, and some of it is genuinely distinctive. The roller washes itself with heated water while it mops, not only back at the dock, which is a real hygiene difference on a long run. The battery uses an unusual chemistry that typically survives far more charge cycles than the usual cells.

Editor’s note
The Max 775 is iRobot's answer to a question its customers have been asking for two years: when would a Roomba get the roller-mop-and-station treatment the Chinese flagships made standard? This is that machine – a 200 RPM self-washing roller mop, a dock that scrubs it with 75 C water, PerfectEdge pad extension into corners, and LiDAR navigation – at $999.99, squarely against the Roborocks and Dreames it imitates.
Some of it is genuinely distinctive. The roller washes itself with heated water while it mops, not just back at the dock, which is a real hygiene difference on a long run. The battery is lithium-iron-phosphate, an unusual chemistry choice that typically survives far more charge cycles than the usual cells. And over carpet the roller hides behind a retracting cover rather than lifting a wet pad a few millimetres – a different answer to the damp-carpet problem, though iRobot publishes no measurement for it.
What iRobot will not tell you is suction. Amazon's listing shouts 30,000 Pa; iRobot itself claims only '4X more power-lifting suction' than a Roomba 105 and publishes no pascal figure anywhere. I have left the suction cell empty, and I would treat the Amazon number as marketing until iRobot stands behind one. No dustbin, tank or noise figures are published either.
Be realistic about the dock, too: roughly 45 cm wide, 43 cm tall and 8.6 kg – it needs a dedicated corner, not a gap under a console.
With six Amazon reviews so far, nobody can honestly tell you how it holds up. I would buy it if I wanted this class of machine and Roomba's app and parts ecosystem specifically; if brand is open, the equivalent Roborock publishes the numbers iRobot keeps to itself.

The bottom line
The iRobot Roomba Max 775 earns a VS Score of 49, a solid mid-pack result among the 50 robot vacuums we compare here.
- Who it’s for
- Committed Roomba households wanting the full self-maintaining flagship – roller mop, heated wash, corner-reaching pad – inside iRobot's app and parts ecosystem.
- Who should look elsewhere
- Spec-sheet shoppers. iRobot publishes no suction, bin, tank or noise figures, so on paper the $999.99 flagship loses arguments its hardware might win.
- The trade-off that matters
- You accept iRobot's silence on the numbers – and a 19 lb dock needing a dedicated corner – in exchange for a genuinely self-cleaning roller mop and an LFP battery built to last.
- The main alternative
- Roborock's Qrevo Curv delivers the same roller-mop-and-dock formula with every specification published, and a longer track record in this class.
The VS Score is calculated from the weighted specifications above, measured against every other robot vacuums we track — a shortlisting guide, not a substitute for your own priorities. See how we score.
