LB4 Digital Pro Superleggera

Superlight backpack vacuum cleaner

This machine has been designed down to the smallest details to achieve high performance, large filter bag capacity, filtering at the highest level while still being extremely small in size and weight.
LB4 is the "world's lightest" backpack vacuum cleaner, only 3.8 kg battery included!

This obvious advantage combined with the comfort provided by the padded, breathable backrest and fully adjustable padded straps, allows use for many hours a day without fatiguing the operator.

The brushless motor of the digital vacuum cleaner ensures high performance and excellent cleaning results with low power consumption. The accessories with which the model is equipped and the additional options available make the LB4 a multifunctional professional appliance, suitable for both floor and carpet cleaning.

Description

LB4 is a multifunctional machine, and thanks to its tapered shape and compact size, it lends itself perfectly to transformation into a trolley vacuum cleaner. It is sufficient to disassemble the shoulder strap kit (4 screws) and screw on 4 pivoting wheels (optional). The machine rotates on itself and perfectly follows the direction desired by the operator without any effort. A convenient handle is placed on the top of the machine for carrying it or parking it in an upright position.

The brushless digital motor is the result of long development work hand in hand with the development of electronic management. The result in terms of size, weight(only 450g), performance and noise is truly outstanding when compared with the best brushless motors on the market today. We were able to reduce consumption by about 50% for the same performance compared to the excellent Rotafil brush motor mounted on the LB4 L-ion, this resulted in the machine, working 60 min. at continuous duty. We also fine-tuned the “turbo” function on each speed so as to have 1 min. of super suction if needed.

ThePB14e L-ion cordless power brush is available for deep vacuuming on carpets.
