It is the more affordable of the two and the only one that is Matter certified now, reaching Apple Home, SmartThings and Home Assistant and adding 5 GHz Wi-Fi.

What the differences mean

Navigation

The iRobot Roomba Plus 678 Combo Robot + AutoWash Dock maps with LiDAR, which works in the dark, while the iRobot Roomba Combo 10 Max robot + AutoWash dock uses a camera that needs the lights on. In dim rooms or on evening schedules the newer robot has the edge.

Smart home reach

The iRobot Roomba Combo 10 Max robot + AutoWash dock is Matter certified today and reaches Apple Home, SmartThings and Home Assistant, on 2.4 and 5 GHz Wi-Fi. The iRobot Roomba Plus 678 Combo Robot + AutoWash Dock is waiting on Matter certification and stays on 2.4 GHz, working through Alexa, Google Home and Siri Shortcuts for now.

Mopping

The iRobot Roomba Plus 678 Combo Robot + AutoWash Dock pre-treats stains with a pressurized spray, scrubs with a heated roller and dispenses its own detergent. The iRobot Roomba Combo 10 Max robot + AutoWash dock uses a retracting pad and has no automatic dispenser, which owners describe as more of a wet wipe.

Brushes

The iRobot Roomba Plus 678 Combo Robot + AutoWash Dock documents a hair-cutting multi-surface main brush and an anti-tangle edge-sweeping brush, aimed at long hair. The iRobot Roomba Combo 10 Max robot + AutoWash dock lists a side brush without that wording.

Which one to buy if

What owners say

iRobot Roomba Combo 10 Max robot + AutoWash dock owners report a machine that shines at first and then sours: a strong opening few weeks give way to unfinished jobs, a robot that cannot find its dock, and recurring bin and dirty-water errors, with support slow to resolve them. What they praise is consistent, mapping ahead of recent Roombas, a dock that empties, washes and dries the mop without help, and smart home support that reaches Apple Home. Their cautions are the camera navigation that needs the lights on, mopping that wipes more than it scrubs, and a pad that can stay damp and turn musty.
