Its 5 L dock bag stretches to about 150 days and it carries a three-year warranty, where the Shark PowerDetect ThermaCharged RV2920XE offers two and washes its mop pad with 185 F water the Dreame cannot match. The Dreame D20 Pro Plus also runs about 285 minutes against 180, though its 13,000 Pa suction is the weaker figure and its mop is a trailing pad rather than a washing system. The Shark brings heated mop washing and drying plus stronger mopping, but also recurring owner reports of dock and water faults. Pick the Dreame D20 Pro Plus for value and runtime, and the Shark PowerDetect ThermaCharged RV2920XE if heated mop care is the point.

What the differences mean

Mop care

The Shark PowerDetect ThermaCharged RV2920XE washes its mop pad with 185 F water and dries it, which owners say is the difference between a pad that cleans and one that smears. The Dreame D20 Pro Plus uses a trailing pad with no washing or drying at the base.

Runtime

The Dreame D20 Pro Plus is rated at about 285 minutes against 180 on the Shark PowerDetect ThermaCharged RV2920XE, so it covers a larger floor before it needs to recharge, though the Shark can finish a typical home on one charge when vacuuming only.

Warranty

The Dreame D20 Pro Plus carries three years of cover, longer than the two on the Shark PowerDetect ThermaCharged RV2920XE, which matters given the faults owners report on the Shark base.

Dock bag

The Dreame D20 Pro Plus empties into a 5 L bag rated for about 150 days. The Shark PowerDetect ThermaCharged RV2920XE also self-empties, but its base holds less, so heavy-shedding homes will empty it more often.

Onboard bin and child lock

The Dreame D20 Pro Plus carries a 500 ml onboard bin and a child lock, against 379 ml and no child lock on the Shark PowerDetect ThermaCharged RV2920XE, so the Dreame holds more between dock visits and is safer around small hands.

What owners say

Dreame D20 Pro Plus owners praise mapping that reads a mixed-floor home correctly on the first run, pet-hair pickup, quiet overnight running and the 5 L dock bag that stretches months. One operator runs four across a large facility on rough concrete, which speaks to durability under heavy use. Their complaints are uneven: several report weak suction, hair sticking in the brush, debris clumping on the mop pad, bags jamming in the base, charging failures and expensive parts. Shark PowerDetect ThermaCharged RV2920XE owners describe whole-home coverage on one charge when vacuuming only, outstanding mopping on wood and tile, heated mop washing and quiet, accurate mapping. Their recurring faults are failing to leave or return to the dock, false obstruction reports during mop self-cleaning and water dispensing stopping within months on some units.
