The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is rated for 200 minutes per charge against 120 on the iRobot Roomba 705X, a gap that shows up on any larger floor plan in a single run.
iRobot lists 22000Pa for the Roomba Plus 515 Combo Robot + AutoWash Dock and 13000Pa for the Roomba 705X, so the mid-range model actually has the stronger rated motor.
The iRobot Roomba 705X adds 5 GHz Wi-Fi and Apple Home, SmartThings, Home Assistant and Matter. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock stays on Google Home and Alexa over 2.4 GHz.
The iRobot Roomba 705X dispenses cleaning solution automatically at the dock. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is detergent compatible but the solution is added to the tank by hand.
At 84 mm the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is slimmer than the 105 mm iRobot Roomba 705X, and it is the lower priced of the two, so it also wins on reach and cost.
The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock runs 200 minutes against 120 and is the cheaper robot, so it covers more floor for less.
The iRobot Roomba 705X adds Apple Home, SmartThings, Home Assistant and Matter plus 5 GHz Wi-Fi, none of which the Plus 515 Combo has.
The iRobot Roomba 705X dispenses cleaning solution automatically, while on the Plus 515 Combo the solution is poured in by hand.
The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is 84 mm tall, against 105 mm for the iRobot Roomba 705X.
Owners of the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock lead with the vacuuming: 22000Pa that lifts pet hair off wood, tile, vinyl and low rugs, an accurate LiDAR map, and a battery that covers a full floor before it returns to recharge. They appreciate the AutoWash dock for emptying the bin and heat-drying the mop pads, and the app for room selection and no-go zones. Their warnings are about mopping, which they rate only decent, the round pads that can snag on cords or pop off, a dirty water tank that smells if not emptied promptly, and a loud self-emptying cycle. Many also mention the 2.4 GHz-only setup as the first hurdle, and a handful returned the unit over the connection alone.
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
