What the differences mean

Mop washing

The Shark PowerDetect ThermaCharged RV2920XE washes and dries the mop, including 185 F water, and it lifts the pad on carpet. The Dreame D20 Air Plus mops with a flat pad and does not wash, dry or lift, and its 0.28 L tank is refilled by hand. If the mop is why you are shopping, only the Shark is maintaining it. The Dreame is a vacuum that can damp a floor.

Runtime and onboard bin

The Shark PowerDetect ThermaCharged RV2920XE is rated for 180 minutes with a 379 ml bin on the robot. The Dreame D20 Air Plus is rated for 150 minutes with 220 ml on the robot. The Dreame's dock is the larger one, at 4 L, so bag changes can still be rare. The Shark's longer run is what matters before the robot ever reaches that dock.

Warranty and price

The Dreame D20 Air Plus is covered for 3 years and is the more affordable robot. The Shark PowerDetect ThermaCharged RV2920XE is covered for 2 years. Both support Alexa, Google Home and Home Assistant, and neither supports Apple Home, SmartThings or Matter. Warranty and price are the Dreame's case. A washed mop is the Shark's.

Child lock and noise

The Dreame D20 Air Plus has a child lock and lists 76 dB. The Shark PowerDetect ThermaCharged RV2920XE has no child lock. Shark owners still describe the robot as quiet, while 76 dB sits in the loud class of published figures. The lock is unambiguous: a toddler can start the Shark, and cannot start a locked Dreame.

What owners say

Owners of both want pet hair gone with less daily work, then they inherit different maintenance. Dreame D20 Air Plus owners praise 20,000 Pa, an anti-tangle brush, accurate maps and a 4 L dock they leave alone for a long stretch, while they say the flat pad does not wash, dry or lift, the small tank is a hand refill, and the turret blocks some furniture. Shark PowerDetect ThermaCharged RV2920XE owners single out 185 F washing on wood and tile and quiet, accurate mapping, and they complain the robot fails to leave or return to the dock, reports false obstructions while the mop cleans, and sometimes stops dispensing water within months.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
