iRobot Roomba 105X vs iRobot Roomba 705X

The iRobot Roomba 705X is the pick overall, leading on owner rating, WiFi connectivity, smart home integrations and a complete self-washing, self-drying mopping system with a long-interval self-emptying dock. The iRobot Roomba 105X remains a solid alternative for buyers who only want vacuuming and prioritize price.

The iRobot Roomba 105X is a vacuum-only robot with no mopping and no self-emptying dock, so its bin has to be emptied by hand. The iRobot Roomba 705X adds a PowerSpin roller mop that is washed with heated water and dried with hot air in its AutoWash dock, plus automatic detergent dispensing and a dock that empties the robot for up to 75 days between manual dumps.

Unusually for a same-brand step-up model, the cheaper iRobot Roomba 105X has the longer runtime at 200 minutes per charge, compared with 180 minutes for the iRobot Roomba 705X. Both recharge automatically, so the practical gap shows up mainly in how much floor each one covers before needing to return to the dock.

The iRobot Roomba 105X connects over 2.4GHz WiFi only and works with Google Home, Alexa and IFTTT. The iRobot Roomba 705X adds 5GHz WiFi and Matter support, and it also works with Apple HomeKit and Siri voice control, which the 105X does not offer. Neither model supports Samsung SmartThings.

Buyers who want dependable, LiDAR-mapped vacuuming for daily upkeep on mixed hard floors and carpet, without paying for mopping or self-emptying, and who value the longer battery life and lower price, should choose the iRobot Roomba 105X.

Buyers who want a hands-off routine, with a self-washing and self-drying roller mop, automatic detergent dispensing, a dock that empties itself for up to 75 days at a time, and Apple HomeKit and Siri support, should choose the iRobot Roomba 705X, accepting shorter battery life and a higher price in exchange.
