iRobot Roomba Combo 10 Max robot + AutoWash dock vs iRobot Roomba Plus 505

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official iRobot site.
2026 verdict
These two iRobot combos share nearly the same spec sheet, and the iRobot Roomba Plus 505 is the robot vacuum that makes more sense to buy, mainly on price.
Both vacuum and mop, self-empty through an AutoWash dock that washes and dries its own pads, map with no-go zones, run about 120 minutes, and connect to the same Google Home, Alexa, Apple HomeKit, Samsung SmartThings, Home Assistant and Matter lineup. The one real technical difference is navigation: the iRobot Roomba Combo 10 Max robot + AutoWash dock uses a camera-based VSLAM system that needs the lights on to map reliably, while the Roomba Plus 505 uses LiDAR, which works in the dark. Beyond that, the Combo 10 Max typically carries a higher price for essentially the same cleaning routine. Buyers who specifically want this dock design and don't mind camera-based navigation can consider the Combo 10 Max; for most people the Roomba Plus 505 delivers the same vacuum-and-mop automation for less.

Frequently Asked Questions

Which is better overall: iRobot Roomba Combo 10 Max robot + AutoWash dock or iRobot Roomba Plus 505?

The two are nearly identical on specs, both mopping and self-emptying through an AutoWash dock with the same smart-home support. The iRobot Roomba Plus 505 comes out ahead mainly because it is typically the more affordable of the two.

What is the biggest difference between them?

Navigation technology. The iRobot Roomba Combo 10 Max robot + AutoWash dock uses a camera-based VSLAM system that needs the lights on to map accurately, while the iRobot Roomba Plus 505 uses LiDAR, which can map and navigate even in the dark.

Do both robots mop and self-empty the same way?

Yes. Both use an AutoWash dock that empties the dustbin and washes and dries the mop pads automatically, and both support multi-room mapping and no-go zones, so their mopping and self-emptying routines are effectively the same.

Does the iRobot Roomba Combo 10 Max robot + AutoWash dock need the lights on to work?

Its camera-based VSLAM navigation performs best with the lights on and can struggle in the dark. The iRobot Roomba Plus 505 avoids this issue entirely by using LiDAR laser navigation instead of a camera.

Who should buy the iRobot Roomba Combo 10 Max robot + AutoWash dock?

Consider it if you specifically want this AutoWash dock model and are comfortable with camera-based navigation that works best with the lights on, and typical pricing is not a concern.

Who should buy the iRobot Roomba Plus 505?

Choose the iRobot Roomba Plus 505 for essentially the same vacuum-and-mop automation and smart-home support, with LiDAR navigation that works in the dark and typically a lower price.
