iRobot Roomba 415X vs Shark PowerDetect ThermaCharged RV2920XE

The Roomba 415X adds 5GHz alongside 2.4GHz Wi-Fi and pairs IFTTT with Google Home and Alexa, and combined with a considerably longer 360-minute battery against the Shark's 180 minutes and a lower price, that's enough to make it the stronger overall pick. The Shark PowerDetect ThermaCharged RV2920XE counters with a longer two-year warranty against the Roomba's one year, and its NeverTouch Pro dock still washes the mop pad in water heated to 185F, a detail owners specifically credit with lifting dirt rather than smearing it. Both robots dock, self-empty, and wash and dry their own mop pads automatically, so neither demands much daily attention. Buyers who want to cover a larger home on one charge and get broader Wi-Fi and smart home hookup should choose the iRobot Roomba 415X; those who prioritize the longer warranty and hot-water mop washing should consider the Shark PowerDetect ThermaCharged RV2920XE.
