iRobot Roomba 105X vs iRobot Roomba Plus 505

The iRobot Roomba Plus 505 wins overall because it mops as well as vacuums, with a dock that washes and dries the mop pads and empties the bin on its own, and it reaches further into the smart home with Apple HomeKit, Samsung SmartThings, Home Assistant and Matter. The iRobot Roomba 105X counters with a lower price and, notably, a longer runtime per charge.

No. The iRobot Roomba 105X is a vacuum-only robot; mopping, detergent compatibility and every auto-mop feature are unsupported. The iRobot Roomba Plus 505 vacuums and mops in the same pass and washes its own mop pads.

It runs for 200 minutes per charge against 120 minutes on the iRobot Roomba Plus 505, likely because it doesn't need to power a mopping system, water pump or auto-mop-washing dock, all systems the Plus 505 carries.

Yes. Both use Laser (LiDAR) navigation with obstacle detection, cliff detection, multi-room mapping and no-go zones, so the iRobot Roomba 105X isn't giving up any mapping accuracy by being the cheaper, simpler model.

Buyers who only want vacuuming, not mopping, and who value a lower price and a longer runtime between charges over dock automation and broader smart home support.

Buyers who want vacuuming and mopping handled in one robot, with a dock that washes and dries the mop pads and empties the bin automatically, plus support for Apple HomeKit, Home Assistant and Matter.
