It brings a longer warranty, longer battery life, wider smart-home reach and a bigger onboard bin. The Shark PowerDetect ThermaCharged RV2920XE answers with a lower price and its own well-regarded heated mop washing, plus whole-home coverage on a single charge when vacuuming only. Buyers who want the longer warranty and broader smart-home support should choose the Dreame X50 Ultra; those drawn to a lower price with equally strong heated mop washing may prefer the Shark PowerDetect ThermaCharged RV2920XE.
