Verdict

The BLACK+DECKER Dustbuster Slim DVC320B21 is a lightweight 12V cordless handheld vacuum featuring a high-performance digital brushless motor, a 24Wh/35Wh lithium-ion battery, and a dual-speed cyclonic system that provides up to 35 Air Watts of suction power. Key advantages include its ultra-slim 600-gram ergonomic design for tight spaces, a hygienic one-touch empty 120ml transparent dustbowl, washable components, and a versatile charging base with an intelligent, eco-friendly energy-saving system that delivers a runtime of up to 24 minutes on low or 11 minutes on high. However, its downsides include a relatively small 120ml dustbin capacity requiring frequent emptying, a moderate noise level of up to 80 dB on high speed, and a lengthy 4-hour recharge time.
