iRobot Roomba 105 vs iRobot Roomba 205

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official iRobot site.
2026 verdict
Between these two entry-level LiDAR robot vacuums, the iRobot Roomba 105 pulls ahead mainly on battery life, running roughly 200 minutes per charge against the Roomba 205's 120 minutes, a real difference for anyone covering a larger floor plan in one pass. The Roomba 205 answers with dual-band 2.4GHz and 5GHz Wi-Fi (the 105 is 2.4GHz only) and its space-saving internal DustCompactor, which presses debris down inside the robot so it skips a bulky auto-empty dock entirely. Both are vacuum-only machines with no mopping, no self-emptying dock, and the same LiDAR mapping, no-go zones, and Google Home, Alexa and IFTTT support. Buyers who need more runtime per charge should lean toward the iRobot Roomba 105; those who want a smaller charging footprint and broader Wi-Fi coverage should pick the iRobot Roomba 205.
