Advanced lithium-ion battery technology and superior German engineering solutions make the AL-KO LBV 4090 Li a great cable- and exhaust-free choice for the discerning gardener.

The 40V battery (not included) gives you the power you need to tackle leaves and other small debris with nothing holding you back. A charge time of 1½ hours produces around 20 minutes of operation. The powerful blower produces a maximum of air speed of 200km/h which can be controlled via a rotary wheel.

Not just a blower, the LBV 4090 Li is also vacuum-capable when fitted with the 50 litre collection bag, reducing the volume of debris by a ratio of 10 : 1. Switching between blowing and vacuum functions is easily achieved using a rotary switch.


The EnergyFlex series of battery-powered machines for cable free and effortless garden enjoyment

The AL-KO Energy Flex platform revolves around a powerful 40V powerpack with 4.0Ah and high quality, efficient drivetrains. The range offers cordless performance across a wide range of products from a single battery. An optional 5Ah battery is available for increased run time.
