It has a longer battery at 220 minutes against 180, a 3-year warranty against 2, an automatic detergent dispenser and Matter, Apple Home and SmartThings support that the Shark lacks. The Shark PowerDetect ThermaCharged RV2920XE answers with 185F mop washing and drying, mopping on wood and tile that owners call outstanding and a reputation for quiet, accurate mapping, though Shark leaves its suction rating, tank size and dimensions out of the spec sheet. Both self-empty and use LiDAR navigation. Choose the Dreame X50 Ultra Complete for smart home reach and capacity, and the Shark PowerDetect ThermaCharged RV2920XE for a quiet hard-floor mopper.

What the differences mean

Smart home support

The Dreame X50 Ultra Complete supports Alexa, Google Home, Home Assistant, Matter, Apple Home and SmartThings. The Shark PowerDetect ThermaCharged RV2920XE works with Alexa, Google Home and Home Assistant only, so an Apple Home household is limited to the Dreame.

Battery and warranty

The Dreame X50 Ultra Complete lists 220 minutes and 3 years, against 180 minutes and 2 years for the Shark PowerDetect ThermaCharged RV2920XE. Shark owners say it covers a whole home when it only vacuums, and needs a recharge if it mops in the same run.

Detergent and child lock

The Dreame X50 Ultra Complete has an auto-detergent dispenser and a child lock. The Shark PowerDetect ThermaCharged RV2920XE has neither.

Published specs

The Dreame X50 Ultra Complete states 20000Pa of suction, a 4.5 L water tank and its dimensions. The Shark PowerDetect ThermaCharged RV2920XE does not publish its suction rating, water tank, dimensions or weights, so those cannot be compared. Its onboard bin is 379 ml against 395 ml.

What owners say

Owners of both robots like the hands-off dock, which empties and washes the mop with hot water, and both groups praise accurate mapping. Dreame X50 Ultra Complete owners single out strong pickup of pet hair from carpet, easy zones and schedules and a robot quieter than they expected, while a minority mention glitches after software updates, uneven edge cleaning and shorter real-world battery life. Shark PowerDetect ThermaCharged RV2920XE owners are happiest about mopping on wood and tile, whole-home coverage on one charge when only vacuuming, a quiet run and floor-type detection, including parents running it nightly for a crawling baby. Their complaints are failures to leave or return to the dock, the mop self-clean falsely reporting an obstruction and water dispensing that stops on some units within months.
