Its higher rated suction decides it, at 35,000 Pa against 30,000 Pa for the iRobot Roomba Max 775 Combo Robot + AutoWash Dock, and the newer model adds a heated roller mop that sprays hot mist onto dried messes before it scrubs and reaches further into edges. Everything else is shared: LiDAR mapping with obstacle and cliff detection, no-go zones, a self-emptying AutoWash dock that washes, dries and doses the mop, and Alexa and Google Home support, with the iRobot Roomba Max 775 Combo Robot + AutoWash Dock already live on Matter and the iRobot Roomba Max 875 Combo Robot + AutoWash Dock still waiting on certification. The iRobot Roomba Max 775 Combo Robot + AutoWash Dock is the more affordable of the pair and publishes a 180 minute battery rating, so choose it when the newer mop and the extra suction do not justify the step up.

What the differences mean

Suction power

The iRobot Roomba Max 875 Combo Robot + AutoWash Dock is rated at 35,000 Pa against 30,000 Pa for the iRobot Roomba Max 775 Combo Robot + AutoWash Dock. That gap matters on carpet, where higher pressure pulls embedded grit and pet hair out of the pile instead of skating over it, and it is the clearest reason the newer model is the pick.

Mopping

The iRobot Roomba Max 875 Combo Robot + AutoWash Dock adds a heated ThermaMist spray that loosens dried spills before its PowerSpin roller scrubs, and the roller extends along edges. The iRobot Roomba Max 775 Combo Robot + AutoWash Dock relies on its spinning pads for the same job without the heated pre-treatment.

Brushes

The newer model carries a hair-cutting main brush and an anti-tangle edge-sweeping brush aimed at long hair, while the iRobot Roomba Max 775 Combo Robot + AutoWash Dock lists a side brush without that wording. If shedding hair is your problem, that detail favours the iRobot Roomba Max 875 Combo Robot + AutoWash Dock.

Body and dock size

The iRobot Roomba Max 875 Combo Robot + AutoWash Dock is the slimmer and lighter of the two, at 99.8 mm tall and 5.45 kg against 105 mm and 5.72 kg for the iRobot Roomba Max 775 Combo Robot + AutoWash Dock, so it slips under slightly lower furniture.

Smart home timing

Both are premium iRobot robots with a self-emptying dock, but the iRobot Roomba Max 775 Combo Robot + AutoWash Dock is already a live Matter device that reaches Apple Home, SmartThings and Home Assistant now, while the iRobot Roomba Max 875 Combo Robot + AutoWash Dock is still going through Matter certification and works through Alexa, Google Home and Siri Shortcuts today.

Which one to buy if

Upgrading from the iRobot Roomba Max 775 Combo Robot + AutoWash Dock?

Moving up from the iRobot Roomba Max 775 Combo Robot + AutoWash Dock to the iRobot Roomba Max 875 Combo Robot + AutoWash Dock buys more suction and a more advanced mop, not a different routine. Both map with LiDAR, avoid obstacles, empty, wash, dry and dose their own mops, and answer to Alexa and Google Home. What changes is the cleaning hardware: 35,000 Pa against 30,000 Pa, a heated ThermaMist pre-spray, and a roller that scrubs and extends further along edges. If the iRobot Roomba Max 775 Combo Robot + AutoWash Dock already keeps your floors clean, there is little to gain. If carpet pickup or set-in stains are what you want more of, the step up is the part that adds it.
