Dyson - V15s Detect Submarine vs Shark - Stratos Cordless IZ862H

The V15s Detect Submarine is the clear pick on raw spec strength, leading by 21.4 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

Pick the V15s Detect Submarine if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are suction (aw), dustbin, weight.

The Stratos Cordless IZ862H similarly does not carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
