iRobot Roomba 105 Combo vs Shark PowerDetect Self-Empty

Full Robot Vacuums comparison in 2026

Updated August 2026
Data from Amazon and official iRobot and Shark sites.
2026 verdict
Having a mop is not always enough: the iRobot Roomba 105 Combo can vacuum and mop in one pass, something the vacuum-only Shark PowerDetect Self-Empty cannot do at all, yet the Shark still comes out ahead in this comparison.
The Shark PowerDetect Self-Empty's self-emptying HEPA base and slightly longer runtime (110 minutes against 100) outweigh the iRobot Roomba 105 Combo's mopping and lower typical price. The iRobot Roomba 105 Combo's mop is water-only, with no detergent, auto-washing or auto-drying, and its bin must be emptied by hand every session, while the Shark PowerDetect Self-Empty needs no manual bin emptying and also reaches Home Assistant, which the iRobot Roomba 105 Combo does not support. If mopping matters more than hands-off maintenance, the iRobot Roomba 105 Combo is worth considering; if a self-emptying dock and longer runtime matter more than mopping, choose the Shark PowerDetect Self-Empty.
