Is a Dyson V15 worth the price over a cheaper cordless stick vacuum?

High-trust testing sources including RTINGS and Vacuum Wars consistently rank the Dyson V15 Detect at or near the top for sealed suction and carpet pickup, and verified-purchase reviewers cite battery life that covers a whole home. The trade-off is price and weight: even Dyson owners on r/dyson note the V15 can feel heavy and needs regular canister and filter maintenance. Budget alternatives clean hard floors well but specialist communities widely report weaker carpet performance and shorter battery life.
