iRobot Roomba 105 vs Shark PowerDetect ThermaCharged RV2920XE

The Shark PowerDetect ThermaCharged RV2920XE takes the overall win, since it self-empties its dustbin and mops with a dock that washes and dries its own pads with hot water, on top of a longer warranty than the iRobot Roomba 105. The Roomba 105 stays vacuum-only, so the decision mostly comes down to whether mopping and self-emptying are worth paying more for.

Mopping and dock automation. The Shark PowerDetect ThermaCharged RV2920XE mops with a dock that washes and dries its own pads and empties itself between runs, while the iRobot Roomba 105 has no mopping function and no self-emptying dock at all, requiring the bin to be emptied by hand.

The iRobot Roomba 105 runs longer per charge than the Shark PowerDetect ThermaCharged RV2920XE, which matters most in larger homes where a robot needs to cover more ground before returning to recharge.

Yes, both support Amazon Alexa and Google Home. The iRobot Roomba 105 goes a step further by also supporting IFTTT for custom automations, an integration the Shark PowerDetect ThermaCharged RV2920XE does not list.

Choose the iRobot Roomba 105 if you want a straightforward, budget-friendly vacuum-only robot with LiDAR mapping, strong battery life and no interest in paying for mopping or a self-emptying dock.

Choose the Shark PowerDetect ThermaCharged RV2920XE if you want a single robot that vacuums and mops, empties its own bin, and washes and dries its mop pads with hot water automatically, and you don't mind the higher price for that convenience.
