Shark Detect Pro Self-Empty Robot Vacuum vs Roborock QV 35S Robot Vacuum and Mop

The Shark Detect Pro RV2820AE is the stronger pick for most homes: it self-empties into a bagless HEPA base, runs about two hours, and adapts suction to debris with DirtDetect. The Roborock QV 35S adds mopping and is built around a heavier, larger chassis, but the listed specs are thin and it supports only Alexa. Owners rate the Shark well at 4.5 from 212 ratings; the Roborock's reputation rests on its mapping and mop, not on the details shown here.

• Choose the Shark Detect Pro if you want a self-emptying vacuum with HEPA filtration and long runtime for pet hair and allergies.
• Choose the Roborock QV 35S if you want one machine that vacuums and mops and you already use Alexa.
