Two Roombas, one a pure vacuum and one a combo: the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock takes this for homes that want mopping.

The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock answers with more suction, 30,000 Pa against 22,000 Pa, dual-band Wi-Fi, and Matter support that reaches Apple Home, SmartThings and Home Assistant, none of which the 515 offers.

What the differences mean
Mop or no mop
The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock mops, and its dock washes, heat-dries and lifts the pad. The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock has no mop or water tank at all, so it is strictly a dry-cleaning robot.
Suction
The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock is rated at 30,000 Pa and the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock at 22,000 Pa, so the vacuum-only model has the higher pull for deep carpet.
Runtime
The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is rated at up to 200 minutes, well above the 120 minutes of the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock, though the combo also takes longer to recharge at about 6 hours.
Height
The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is 84 mm tall and the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock 104 mm, so the combo gets under beds and sofas that stop the taller robot.
Smart home reach
The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock uses dual-band Wi-Fi and Matter to reach Apple Home, SmartThings and Home Assistant on top of Alexa and Google Home. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is 2.4 GHz only and works with Alexa and Google Home alone.
Which one to buy if
- you want vacuuming and mopping in one robot
The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is the only one of the two with a mop, and its dock washes and heat-dries the pads.
- you only ever vacuum and want maximum suction
The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock is rated at 30,000 Pa against 22,000 Pa, and its compact dock suits a hallway.

At 84 mm the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock clears more furniture than the 104 mm iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock.

What owners say
Only the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock has owner reviews behind it here. Its owners call vacuuming the clear strength: strong pickup on wood, tile, vinyl and low rugs, with pet hair a recurring success story, plus an accurate LiDAR map that handles stairs and room changes well. The dock draws consistent praise for emptying the bin and washing and heat-drying the pads, which removes chores owners expected to keep doing, and the low body gets under beds. The complaints are specific: setup demands a 2.4 GHz network and dual-band routers cause grief, mopping is only decent and the pads can snag on cords, the dirty water tank smells if it is left, the self-empty cycle is loud, and there is no automatic detergent dispenser.
