What the differences mean

Mopping

The iRobot Roomba Plus 505 vacuums and mops with DualClean spinning pads and SmartScrub, so one run covers hard floors and rugs. The iRobot Roomba 105 is vacuum-only, with no mop, no water tank and no detergent support, so hard-floor mopping stays a separate job.

Self-emptying dock

The iRobot Roomba Plus 505's AutoWash dock empties the bin and washes and dries the mop pads on its own. The iRobot Roomba 105 has no self-emptying dock, so its onboard bin is emptied by hand after runs, which is the chore the Plus 505 removes.

Wi-Fi bands

The iRobot Roomba Plus 505 supports both 2.4 GHz and 5 GHz Wi-Fi, while the iRobot Roomba 105 is 2.4 GHz only. On a modern dual-band router that rarely changes setup, but the 105 can fight a 5 GHz only band.

Smart home support

The iRobot Roomba Plus 505 supports Matter, which brings it into Apple Home, SmartThings and Home Assistant alongside Alexa and Google Home. The iRobot Roomba 105 stops at Alexa, Google Home and IFTTT, so Apple and SmartThings households lose the integration entirely.

Runtime

180 minutes on the iRobot Roomba Plus 505 against 120 minutes on the iRobot Roomba 105. In a larger home that is the difference between one clean pass and a mid-job recharge, and owners of the 105 regularly mention needing that top-up.

Noise

Owners of the iRobot Roomba Plus 505 report it running loud, especially during the dock's self-cleaning cycle, while the iRobot Roomba 105 is described as quieter than older non-mapping robots. In an open-plan home that is worth weighing against the mopping and dock features.

What owners say

Owners of both Roombas praise LiDAR mapping that cleans in organized rows rather than bumping around, easy app scheduling with saved maps and no-go zones, and strong pickup of pet hair for the price. iRobot Roomba 105 owners like the larger dustbin that needs less frequent emptying and quieter running than older robots, but warn that the battery can fall short in larger homes and that suction weakens on medium to high pile carpet. iRobot Roomba Plus 505 owners highlight how fast it maps a floor, its pet-hair pickup on mixed floors and the AutoWash dock that washes and dries the mop pads, while a meaningful share report it runs louder than expected and some hit navigation or mechanical issues after a few months.

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.
