1. Introduksjon
The LEHMANN Haddo Industrial Vacuum Cleaner 2000W is a versatile cleaning device designed for various tasks in industrial settings, workshops, and construction sites. It functions as a wet vacuum, ash vacuum, and dry vacuum, offering comprehensive cleaning capabilities. Equipped with a powerful 2000W motor and an efficient double filtration system, including a washable HEPA filter, it ensures strong suction and reliable impurity retention. Its 20-liter stainless steel tank provides extended operation without frequent emptying, and the integrated blower function adds to its utility for tasks like clearing leaves or inflating items. Mobility is enhanced by wheels, a 1.5m metallic hose, and a 3.5m power cable.
