Verdict

The BLACK+DECKER NSVA315J is a cordless, 4-in-1 stick and handheld vacuum cleaner powered by a 10.8V, 1.5Ah lithium-ion battery that delivers a suction power of 15.8 air watts and a dry airflow of 0.834 m³/min. Weighing just 1.3 kg, it features a 400 ml bagless translucent dust container, a washable cloth filter, and operates at a noise level of 76 dB. Its main characteristics and pros include its extreme lightweight portability, modular versatility to convert from a handheld to an extended stick vacuum, and a wide suction mouth for effortlessly capturing larger debris. However, its notable cons include a very limited runtime of only 11 minutes per charge and an exceptionally long battery recharge time of up to 10 hours.
