Our Verdict
If cleaning performance is your top priority and budget is not a constraint, the Dyson V15 Detect is the superior vacuum. The laser detection and piezo sensor genuinely change how you clean — you can see dust you would otherwise miss.

For most UK households, the Shark offers better value for money.
