LB4 Digital Pro Superleggera
Superlight backpack vacuum cleaner
LB4 is the "world's lightest" battery backpack vacuum cleaner, 3.8 kg (8.4 lb) only 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.
EXTREMELY POWERFUL!
The brushless motor of the digital vacuum cleaner ensures high performance and excellent cleaning results with low power consumption.
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 (450g only), 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.

Why choose it
LITHIUM BATTERY 36V
The 36V-6Ah battery allows work for 60 min. Replacement is very fast and without tools, even without taking the machine off the shoulders, allowing work with a second battery (optional). Total charging is very fast: 90 min. only. The batteries are specific for professional use and have a lifetime of 800 charging cycles.
ACCESSORIES PROVIDED
Blower kit, 2 m flex hose with nozzle and handle with suction, crevice tool, swivel brush, nozzle with bristles, aluminum telescoping hose, patented Lindhaus M28R universal brush. The P30 popcorn brush is optional.
The exuberant suction power can also be harnessed with the blowing function, thanks to the special kit (included) that allows air to be ducted out of the motor. By using a suction hose and an outlet hose, the machine can blow and suck at the same time.
MULTIFUNCTIONAL REMOTE CONTROL
Convenient remote control that clips onto the belt with ON/OFF functions, 3-speed control, full bag light, motor over temperature light, battery level. The remote control has a male metal connector screwed onto the female connector on the machine. The remote control can be easily removed to use the machine as a trolley.
The machine also works without remote control as all functions are duplicated on the machine.

Where to use it
FAQ
How much does the LB4 weigh?
The LB4 is the lightest backpack vacuum cleaner in its class: it weighs just 8.4 lbs, including the battery.
It is designed for extended use thanks to its low weight, adjustable shoulder straps, padded back panel and spacers that keep the machine away from the back, improving comfort and ventilation.
Is it comfortable to wear?
Yes. The backrest is padded, breathable and ergonomically designed to ensure comfort even during long working sessions.
How long does the battery last?
The Lindhaus lithium-ion battery provides up to approximately 60 minutes of runtime, allowing you to complete entire cleaning cycles without interruption.
Is it suitable for cleaning public transport?
Yes. LB4 is particularly well suited for buses, trains and planes thanks to its cable-free design, light weight and ease of manoeuvring in confined spaces.
Is it noisy?
No. The LB4 Digital Pro is designed to minimise noise emissions, in line with CAM requirements for use in sensitive environments.
The noise level ranges from 62 to 65 dB(A), depending on the selected power setting, making it suitable for environments such as hotels, offices, schools and healthcare facilities.
Furthermore, the Rotafil brushless motor helps to reduce vibrations and noise, improving comfort for both the operator and people in the area.
