Lindhaus LB4 L-ion Digital Backpack Vacuum

The Lindhaus LB4 L-ion Digital (SKU 192364681) is billed as the world's lightest backpack vacuum, weighing just 3.8 kg (about 8.4 lb) with the battery installed. Built in Italy as the Superleggera Digital Pro, it gives commercial cleaning staff cordless freedom and all-day comfort for stairs, theaters, vehicles, and crowded spaces where uprights and cords get in the way.

A 36V 6Ah lithium-ion battery powers a brushless digital motor that cuts consumption by roughly 50% versus the standard brush motor, extending continuous service to as much as 60 minutes; the battery swaps out in seconds with no tools and recharges in about 90 minutes. This configuration ships with one battery and a charger. The vacuum delivers 400W of motor power, 50" of water lift, and 63 CFM of airflow.

Six levels of filtration finish with a HEPA H13 filter for 99.97% net efficiency at 0.3 microns—ideal for healthcare, hospitality, and allergen-sensitive environments. The ergonomic harness distributes the light load across the back for fatigue-free operation. Supplied as a genuine Lindhaus machine by an authorized Lindhaus dealer with full factory warranty and parts support.
