Shark PowerDetect Self-Empty vs Shark PowerDetect ThermaCharged RV2920XE

Vacuum-only against vacuum-and-mop within the same Shark family: Shark PowerDetect ThermaCharged RV2920XE wins this robot vacuum comparison against Shark PowerDetect Self-Empty by adding mopping, a bigger onboard dustbin, a higher rating, a longer warranty and longer battery life. Shark PowerDetect Self-Empty answers with only a lower price, which is the entire reason to consider it once mopping is off the table. Both robots share the same PowerDetect navigation and Alexa and Google Home support, so the choice really is about whether hot-water mop washing is worth paying for. Owners of the ThermaCharged model report a handful of docking and water-dispensing issues on some units, a wrinkle the simpler Self-Empty avoids by not having a mop system at all. Buyers who want mopping and are willing to pay more for it should pick Shark PowerDetect ThermaCharged RV2920XE; anyone who only vacuums should save money with Shark PowerDetect Self-Empty.
