What the differences mean

Suction power

The iRobot Roomba Max 775 Combo Robot + AutoWash Dock is rated at 30,000 Pa and the iRobot Roomba Plus 415 Combo Robot + AutoWash Dock at 20,000 Pa. The extra pressure helps the Max 775 lift embedded grit and pet hair from carpet pile, which is where suction is felt most.

Smart home reach

The iRobot Roomba Max 775 Combo Robot + AutoWash Dock is Matter certified and works with Apple Home, SmartThings and Home Assistant as well as Alexa and Google Home. The iRobot Roomba Plus 415 Combo Robot + AutoWash Dock stops at Alexa and Google Home and has no Matter, Apple Home or SmartThings support.

Detergent dosing

The iRobot Roomba Max 775 Combo Robot + AutoWash Dock mixes and dispenses cleaning solution automatically as part of its dock routine. The iRobot Roomba Plus 415 Combo Robot + AutoWash Dock works with solution too, but you pour it in by hand, and owners are advised to stick to iRobot-approved solution.

Battery life

The iRobot Roomba Plus 415 Combo Robot + AutoWash Dock is rated at 200 minutes per charge against 180 for the iRobot Roomba Max 775 Combo Robot + AutoWash Dock. Both recharge in about 6 hours and return to the dock on their own when the battery runs low.

Size and weight

The iRobot Roomba Plus 415 Combo Robot + AutoWash Dock is the much smaller robot, at 298 by 303 by 84 mm and 2.9 kg, against 372 by 366 by 105 mm and 5.72 kg for the iRobot Roomba Max 775 Combo Robot + AutoWash Dock, so it fits under lower furniture.

Which one to buy if

What owners say

iRobot Roomba Plus 415 Combo Robot + AutoWash Dock owners describe a machine that earns its place in a pet household. They report strong pickup of dog and cat hair on both carpet and hard floors, a slim body that reaches under beds and sofas older Roombas could not, and fast, orderly LiDAR mapping that avoids stairs and rarely gets stuck. The dock draws the most praise: it empties the bin, washes the spinning pads and heat-dries them, and owners say the drying keeps mildew and odour away. Their recurring complaints are an app they find clunky, small cords and cat toys still getting caught, a loud but brief self-empty cycle, and having to add cleaning solution by hand.
