It runs up to 285 minutes against 110, carries a 3-year warranty against 1 year, holds 500ml in its onboard bin against 189ml and adds a trailing mop pad the Shark does not have. The Shark PowerDetect Self-Empty is a vacuum-only machine whose owners credit it for rarely getting stuck, thanks to NeverStuck lifting over thresholds, and for keeping up with heavy pet shedding. Both map with LiDAR, work with Alexa, Google Home and Home Assistant and empty into their base. Pick the Dreame D20 Pro Plus for long runs and a light mop, and the Shark PowerDetect Self-Empty for a pet home with thresholds and rug edges to cross.

What the differences mean

Mopping

The Dreame D20 Pro Plus drags a mop pad from a 0.35L tank, enough for a light pass on hard floors that you rinse by hand. The Shark PowerDetect Self-Empty does not mop at all.

Runtime

Up to 285 minutes on the Dreame D20 Pro Plus against 110 on the Shark PowerDetect Self-Empty. In a large home the Shark will head back to recharge mid-run where the Dreame finishes in one go.

Onboard bin

The Dreame D20 Pro Plus holds 500ml between dock visits and the Shark PowerDetect Self-Empty 189ml. Both empty into their base, so the gap mostly shows on a big, hairy floor where the small bin fills before the run ends.

Warranty

3 years on the Dreame D20 Pro Plus against 1 year on the Shark PowerDetect Self-Empty.

Suction

The Dreame D20 Pro Plus is rated at 13000Pa. Shark does not publish a figure for the Shark PowerDetect Self-Empty, which boosts power where DirtDetect senses more debris, so the two cannot be ranked on paper.

Which one to buy if

What owners say

Owners of both robots agree on pet hair: households with dogs and cats say each one keeps up with shedding on carpet and hard floors. Dreame D20 Pro Plus owners single out a first map that gets every room right, quiet overnight runs in a bedroom and a dust bag that lasts for months, while their complaints split between weak suction reports, hair wrapped in the brush, debris clumping on the mop pad, bags jamming in the base and charging failures. Shark PowerDetect Self-Empty owners talk about a robot that does not get lost or wedged under furniture, but they call the SharkClean app plain, describe registration and Wi-Fi pairing trouble on day one, and some report missed patches or bumping into walls.

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.
