The 705X adds a PowerSpin roller mop with a dock that washes, dries and doses it, on top of the self-emptying the pair share, and it is the more affordable of the two right now. On the vacuum side they are twins: both are rated at 13,000 Pa, both run 120 minutes, both use LiDAR with PrecisionVision avoidance and both reach Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The Roomba Max 705 counters with a far smaller AutoEmpty dock, about 213 x 170 x 282 mm against the much larger AutoWash station. Pick the iRobot Roomba 705X for mopping and the iRobot Roomba Max 705 if you want dry-only cleaning from a compact dock.

What the differences mean

Mopping

The iRobot Roomba 705X mops with a PowerSpin roller that its AutoWash dock washes, dries and doses. The iRobot Roomba Max 705 has no mopping hardware at all.

Dock size

The iRobot Roomba 705X AutoWash station is about 457 x 429 x 432 mm. The iRobot Roomba Max 705 AutoEmpty dock is roughly 213 x 170 x 282 mm, so it takes far less floor space.

Detergent

The iRobot Roomba 705X dispenses cleaning solution automatically. The iRobot Roomba Max 705 needs none, because it does not mop.

Onboard bin

The iRobot Roomba Max 705 carries a 275 ml onboard bin. iRobot does not publish that figure for the iRobot Roomba 705X, though both empty into their dock.

The vacuum side is shared

Both are rated at 13,000 Pa with Automatic Carpet Boost, both run 120 minutes, both use the same LiDAR navigation and PrecisionVision avoidance, and both support the same six platforms. Buying decisions here turn only on mopping and dock size.

Which one to buy if

What owners say

iRobot Roomba Max 705 owners, many upgrading from older Roombas, single out the LiDAR mapping as faster and more accurate than what came before, with less bumping into furniture and fewer rescues. They call the AutoEmpty dock a genuine convenience, since the robot runs for weeks without anyone touching the bin, and they report strong pickup of pet hair from both hardwood and carpet, running quieter than earlier generations. The most repeated complaint is Wi-Fi setup, where router passwords with special characters can stop the app from finishing, forcing a password change or a support call. A few mention the dock not fully clearing the bin and one a false stuck error.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
