Black & Decker confirms its position in the vacuum leaf blower market with the GWC3600L20. The wireless model competes with high-performance devices, choosing to switch to mains power in the majority of cases. Black & Decker’s GWC3600L20 is an exception to the rule by opting for a rechargeable lithium battery. This makes it one of the few in its category to offer this power supply mode, while at the same time offering a multitude of functions. To make the difference, the unit displays a small 36 volt, and two modes of operation. The first, in turbo, announces a suction capacity of 3.5 m per minute. The second, in eco, limits this performance to 2.7 m per minute.

The small suction performance is backed up by a blowing speed of 182 km/h to 218/km/h in turbo, compared to 145 km/h in eco. The Black & Decker GWC3600L20 also features a shredding option with a 7:1 ratio. Adapted to the small capacity of the filling bag, this capacity is more than enough for cleaning a terrace, a driveway, or a small garden. This is one of the only Black & Decker models to use a Lithium battery. Charging recommendation is spread over a few hours, and offers an autonomy of 32mn in turbo mode, compared to 60m in economy mode.

Battery life varies greatly depending on the charging time and the mode of use. The 17.5 l of the collection bag is significantly less than that of a mains operated model. However, the weight remains equivalent to that of a larger reference, with 3.5 kg in blowing mode. The weight increases slightly in suction, with concentrated power in a spiral pattern, following the flow of focused air that the device is equipped with. The GWC3600L20 from Black & Decker announces maneuverability and lightness, for maximum comfort of use.

Black & Decker puts forward proven functionality on this GWC3600L20. The vacuum leaf blower is equipped with a powerful battery, defying competing models that today are few and far between to offer equivalent features. The specificities are promising, and we can only succumb to what the brand offers. The unit announces an extended range of 60 m in economy mode, compared to 32 minutes in turbo mode.

It can be said that a frequent switch from turbo to eco can split the pear in half. The Lithium battery can last for more than 35 minutes, but not more than 60 minutes. The performance is notable, because Black & Decker manages to offer a much longer life span than other models that must be charged after a few minutes.

The tool becomes slightly heavier when the vacuum function is activated, especially when the user turns on the turbo mode. In spite of the power of the focused air flow, the noise generated by the device remains bearable… as long as it is not spread out. At maximized power, the sound output can be a source of discomfort for even the most insensitive ears. While hearing protection is not essential, it is strongly recommended.

The lithium battery, for its part, is easy to recharge, as you only need to plug in the device to get it to juice again. However, the charging time can be long, which is why users only charge it at night. The efficiency of the shredder, finally, is remarkable on a device of this trunk. While it is slower and less efficient than a model without batteries, it is still relevant enough to optimize the available storage. The ratio is only 7:1, but is still satisfactory for a small vacuum leaf blower-blower for household use. Dry leaves, as well as wet ones, are easily sucked up without the machine experiencing any difficulty during this task.
