Dyson - Gen5detect Absolute vs Shark - Detect Pro Cordless IW1511

The Gen5detect Absolute is the clear pick on raw spec strength, leading by 21.5 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 Gen5detect Absolute if you care most about suction (aw) and battery. The biggest gaps in its favor are suction (aw), battery, dustbin, among others.
