Wet Vacuum Cleaner – Numatic WV1800DH Wet & Dry Industrial Vacuum

With its 70L wet capacity, robust StructoFoam construction, and easy-drain dump hose system, the WV1800DH offers exceptional performance for users who need to remove large volumes of water quickly, safely and efficiently. Built around a tough tubular steel chassis and equipped with a strong 1060W commercial-grade motor, this wet vac is ideal for demanding environments where reliability is essential.
