Solid Lithium-Ion Battery

This Black & Decker sweeper packs a solid 40-volt lithium ion battery which is much stronger than other types of batteries, allowing for longer operation times and longer battery life. In a single full charge, this sweeper can work for at least an hour or so, depending on the power setting that is used. For instance, when the power setting is set to the highest, the sweeper will work for around 20 to 30 minutes before running out of charge. It comes with an LED battery indicator to let users know how much battery power is left.

All-around Sweeping Equipment

At 120 mph of wind power, this sweeper is strong enough to clear most kind of dirt and debris. Many use it to clean their patios and decks, as well as walkways and driveways. It also sports a built-in scraper which is used to unstuck or loosen stuck dirt and debris. At this power rate though, it can be a challenge to remove heavier debris like large, wet leaves and trimmings like small branches or twigs.

Compact and Lightweight Design

At less than 5 pounds, this is definitely one of the most lightweight sweepers on the market today. This compact and lightweight feature makes it ideal for all-around home use and is perfect for seniors who prefer to do their own cleaning. This feature, along with its comfortable and soft grip, allows the user to use it for extended periods without having to suffer much from strain on their arm and wrist.

Low Noise

This machine creates low noise levels while being operated, thanks to the battery-powered electric motor which is much quieter than gas-powered versions. This then reduces the noise impact on the user’s ears and keeps complaints low from disturbed neighbours.

Frequently Asked Questions

Q: Can the 40-volt lithium ion battery be swapped with a 20-volt battery?
A: No, the voltage difference is too big. Most users were able to use a 36-volt lithium ion battery though from other Black & Decker tools.

Q: Does it have a dual voltage selection?
A: No. It should only be used with 110-volts and is not compatible with 220-volts.

Q: Are there nozzle extensions available?
A: There are no attachments or accessories available for this sweeper.

Final Verdict

This Black & Decker cordless sweeper is a great choice for homeowners who have very modest needs for their outdoor cleaning. With air speeds of up to 120 mph, it is able to effectively blow away most types of dirt and debris. In line with this, it is not recommended for commercial use and large outdoor cleaning projects, given that the air speed is not as strong as those created by gas-powered units. In addition, the battery life of an hour or so will not be enough to clear acres of leaves or debris, unless the user has an extra battery pack. Still though, depending on the volume of debris to be used and size of the area to be cleaned, this sweeper should be more than enough to handle small tasks.
