iRobot Roomba 415X vs iRobot Roomba Max 775 Combo Robot + AutoWash Dock

What owners say

Owners of the iRobot Roomba 415X consistently put the AutoWash dock first: it empties the dustbin and washes and heat-dries the mop pads, so an overnight schedule really is hands-off. They praise the 20000Pa suction for pulling dust from floor cracks and handling pet hair, the low 84 mm body that reaches under beds and sofas, and quiet enough runs to schedule at night. Their friction points are the app, which they describe as rough around renaming rooms and confusing error messages, and hair that sometimes tangles around the spinning mop module or roller and needs a weekly clean-out. A few also find the mop does not scrub as hard as a hand pass on set-in stains.
