Verdict

The BLACK+DECKER SVJ520BFSP-QW is an 18V bagless, cordless 2-in-1 stick vacuum cleaner equipped with a 2.0Ah lithium-ion battery (36Wh) that delivers up to 30 air watts of suction power and features a 0.5-liter dust container. Main characteristics and pros include its versatile detachable handheld unit, specialized motorized pet hair beater bar, built-in cotton-fresh fragrance filter to eliminate odors, and intelligent Smart Tech sensors that automatically adjust suction based on floor type, alert you to a clogged filter, and show real-time battery status. However, it suffers from a relatively short maximum runtime of 25 minutes paired with a long 5-hour charge time, and it operates at a loud maximum noise level of 80 decibels.
