Dreame D30 Ultra vs Shark PowerDetect Self-Empty

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official Dreame and Shark sites.
2026 verdict
Why pay for a vacuum-only robot when a mopping one costs less?
That is the question Shark PowerDetect Self-Empty runs into against Dreame D30 Ultra, which wins this robot vacuum comparison on price, warranty, battery life, mopping and dustbin capacity all at once. Shark PowerDetect Self-Empty does not answer with a spec win here, leaning instead on its NeverStuck lifting and dedicated pet-hair pickup for buyers who genuinely never want mopping in the mix. That is a real use case, not a weakness, since some households would rather skip the water tank and consumables entirely. But for anyone comparing the two on paper, Dreame D30 Ultra covers more ground for less money and adds a hygiene routine the Shark cannot match. Choose Shark PowerDetect Self-Empty only if mopping is a feature you would rather not have.
