BLACK+DECKER 20V MAX* Cordless Sweeper with Power Boost (LSW321)

The BLACK+DECKER 20V MAX Cordless Sweeper (LSW321) is designed for clearing leaves, dirt, and outdoor debris from hard surfaces around your property. It provides a lightweight, cordless solution for homeowners who need to clean driveways, sidewalks, decks, and patios without dragging around an extension cord.

This sweeper delivers air speeds up to 130 MPH, giving you enough force to move dry leaves and grit efficiently. For tougher spots, the integrated POWERBOOST function temporarily increases air power to dislodge stubborn debris stuck in crevices. Its quiet operating design helps keep noise levels low while working outdoors. Power comes from an included 20V MAX lithium ion extended runtime battery, which is compatible with other tools in the BLACK+DECKER 20V MAX tool system.

A main constraint to keep in mind is the 25-minute maximum runtime, which makes this sweeper best suited for short cleanup jobs rather than extensive lawn work. Additionally, the feature set is tailored specifically for hard surfaces, so it may not be suitable for heavy, wet yard debris on deep grass.

Verdict: The BLACK+DECKER LSW321 is a practical, low-noise choice for quick outdoor maintenance on driveways, walkways, and decks. It is ideal for existing users of the 20V MAX tool system or anyone needing a compact sweeper for light clearing tasks.
