2026 verdict
The less expensive Roomba of the pair is also the stronger one: the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock wins this matchup on suction and on the dock interval.
It is rated at 30000Pa against 13000Pa, empties into an AutoEmpty dock rated for up to 90 days instead of 75, and recharges in about 3 hours rather than 4.5. Both are vacuum-only Roombas with no mopping, the same 104mm body, LiDAR mapping, PrecisionVision obstacle avoidance and support for Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter over 2.4GHz or 5GHz Wi-Fi. The iRobot Roomba Max 705 is the one owners know, and it is a solid cleaner, but the newer robot simply gives more for less. Pick the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock unless you find the 705 at a price that closes the gap.

What the differences mean
Suction
The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock is rated at 30000Pa and the iRobot Roomba Max 705 at 13000Pa, more than double. On carpet and heavy pet hair that gap is the main reason to choose the newer robot.
Dock interval
The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock empties into a dock rated for up to 90 days and the iRobot Roomba Max 705 for up to 75. Neither number is a promise, but the newer dock asks less of you.
Recharge time
The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock recharges in about 3 hours and the iRobot Roomba Max 705 in about 4.5. On a large floor that is the difference between pausing briefly and pausing for most of an afternoon.
Onboard bin
The iRobot Roomba Max 705 carries a 275ml onboard bin, while the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock does not publish one. Both empty into the dock, so the onboard bin only matters for how often the robot tops itself up.
Everything else
Height, navigation and platform support are the same: both stand 104mm tall, map with LiDAR, add PrecisionVision obstacle avoidance, and work with Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. Neither mops, and both list Bluetooth.
Which one to buy if
- you want the strongest suction for carpet and pet hair
The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock is rated at 30000Pa against 13000Pa for the Max 705.
- you want the dock to go longest between changes
Its AutoEmpty dock is rated for up to 90 days, against 75 for the iRobot Roomba Max 705.
- you want the faster recharge
The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock recharges in about 3 hours, against about 4.5 for the Max 705.
- you already own a Max 705 that keeps up
Both are vacuum-only Roombas on the same AutoEmpty design, so a 705 that cleans well gains little beyond suction.
- you find the older robot at a much lower price
The iRobot Roomba Max 705 shares the mapping, avoidance and platform support, so a steep saving can make it the smarter buy.

What owners say
Owners of the iRobot Roomba Max 705 are clear about why they bought it: the LiDAR mapping is faster and more accurate than the Roombas they came from, so it bumps furniture less and needs rescuing less often. They call the AutoEmpty dock a real convenience, letting the robot run for weeks without a bin to empty, and they highlight strong pet-hair pickup from hardwood and carpet and quieter operation than earlier generations. The repeated complaint is Wi-Fi setup, where router passwords with special characters can stop the app connecting, and a few report the dock not fully clearing the bin or a false stuck error.
Upgrading from the iRobot Roomba Max 705?
Moving from the iRobot Roomba Max 705 to the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock buys three things: far more rated suction, up to 90 days between dock changes instead of 75, and a recharge in about 3 hours instead of 4.5. Everything else stays the same, from the 104mm body and LiDAR mapping to PrecisionVision obstacle avoidance, the vacuum-only design and support for every major smart home platform. If your Max 705 already keeps the floors clean, there is little to gain. If carpet and pet hair are a struggle, or the robot spends too long on the charger, the Max 715 is the step up that fixes it.
