Dyson V8 Cyclone Cordless Vacuum
A genuinely decent old vacuum at a genuinely bad price. The 3.4-star owner rating isn't about the machine breaking; it's about buyers doing the math after checkout.
Best for: Almost no one at this price. If it drops under $400 on sale, it becomes a defensible light-duty pick for small hard-floor homes that want the Dyson badge.

Dyson build quality carrying a wet-mop system owners find fussier than the badge promised. Better than the category's worst, priced like its best, rated like neither.
Best for: Dyson-committed hard-floor households who want one branded machine for dry and wet, understand roller-drying discipline, and catch it discounted.
