Product FAQ's

🔍 Numatic WVD1800DH: Frequently Asked Questions

❓ What does the "DH" stand for in WVD1800DH?
💬 The "DH" stands for Dump Hose. This signifies that the machine is equipped with a rear-mounted discharge hose, allowing you to empty the 70L tank using gravity. This is a massive advantage over the "Tipper" models, as it eliminates the need to lift or tilt the heavy drum when full of water.

❓ What is the difference between the WV1800DH and the WVD1800DH?
💬 The "D" in WVD stands for Duplex (Twin Motor). The WV1800DH has a single 1000W motor, while the WVD1800DH features two 1000W TwinFlo motors. This provides significantly higher airflow (98 L/sec vs 49 L/sec), making it much faster at clearing large-scale floods and heavy industrial spills.

❓ Is the WVD1800DH suitable for use on construction sites?
💬 Yes, provided you select the 110V version. While the standard 230V model is perfect for commercial use, the 110V variant is specifically designed for site safety compliance. Its Structofoam construction is also impact-resistant, handling the "rough and tumble" of a busy building site.

❓ Why has the suction power dropped on my machine?
💬 Suction loss is usually caused by one of three things:

Full Tank: The safety float valve has activated to prevent overfilling. Empty the drum via the dump hose.

Dirty Filter: The internal trash basket or secondary filter is clogged with debris.

Blockage: Check the 38mm hose and the extra-wide floor tool for obstructions like stones or rags.

❓ Can I use the WVD1800DH for dry vacuuming?
💬 Technically, this is a dedicated Wet Vacuum. While some Numatic models are "Wet & Dry," the 1800DH series is optimized for liquid recovery. If you need to switch to dry use, you would need to fit a completely different dry filter and a dust bag, but it is highly recommended to keep this machine specifically for wet tasks to protect the motors.

❓ How does the safety float valve work?
💬 The WVD1800DH contains a spinning ball safety float cage. As the water level rises, the ball floats upward. Once the tank is at its 70L capacity, the ball seals the motor inlet, causing a noticeable change in the motor's pitch (it will sound higher-pitched). This tells the operator to stop and empty the machine.

❓ What should I do if the dump hose gets blocked?
💬 The machine is fitted with an internal trash basket filter specifically to prevent this. It catches large debris before it can enter the discharge path. If the hose does block, ensure the rubber bung is removed and use a flexible drain rod or water pressure to clear the obstruction.

❓ Is the power cable easy to replace if damaged?
💬 Yes. This model features the NuCable system, which uses a simple plug-and-play connection on the power head. This allows you to replace a frayed or cut cable on-site in seconds without needing an electrician or opening the motor housing.

❓ What tools are included in the BS7 kit?
💬 The BS7 kit is a professional 38mm stainless steel accessory set. It includes a 2.4m Nuflex hose, a three-piece stainless steel tube set, and the 400mm ProFlo wet pick-up tool, which features durable rubber blades for streak-free water extraction.

Numatic WVD1800DH Industrial Twin Motor Wet Vacuum Cleaner

The Numatic WVD1800DH is the ultimate powerhouse for heavy-duty liquid recovery. Engineered for the "rough and tumble" of industrial environments, this machine combines a massive 70-litre capacity with a high-performance Duplex Twin-Motor setup. Whether you are managing flood recovery, cleaning up workshop spills, or maintaining large commercial facilities, the WVD1800DH delivers unrivalled suction and durability.

The "DH" designation stands for Dump Hose, a critical feature that allows for effortless, no-lift emptying via a rear-mounted discharge hose—saving time and reducing operator strain.

Numatic WVD1800DH Key Features & Performance

Dominate large-scale liquid extraction with the WVD1800DH. Built with Numatic’s legendary Structofoam technology, this industrial wet vacuum provides professional-grade power that never quits.

  • Twin-Motor Performance: Equipped with two 1000W TwinFlo™ 2-stage bypass motors, providing a combined 2000W of extreme suction for rapid water removal.
  • Massive 70L Wet Capacity: The giant drum allows for long cleaning cycles without constant interruptions, making it ideal for large flood events or deep cleaning tasks.
  • No-Lift Dump Hose Emptying: Features a simple, rear-mounted dump hose that uses gravity to drain the tank directly into floor drains or waste points.
  • Heavy-Duty Structofoam Construction: Both the head and the body are made from Structofoam—a unique composite material that is as strong as steel but as light as plastic, ensuring it won't dent, rust, or crack.
  • Spinning Ball Safety Float Valve: An internal safety cage prevents the machine from overfilling, automatically cutting off suction when the tank reaches capacity to protect the motors.
  • Trash Basket Inlet Filter: An innovative internal basket catches larger debris (like mops strands or stones) to prevent the dump hose from clogging during drainage.
  • NuCable Replaceable Cable System: The 10-metre power cable can be swapped in seconds without an engineer, minimizing downtime if the cord is damaged on-site.

🏠 Who and Where is the WVD1800DH Best Suited?

Specifically designed for contractors and facility managers, the WVD1800DH is a high-mobility workhorse that excels in the toughest environments.

  • Flood Recovery & Salvage: The twin-motor suction is powerful enough to lift deep standing water quickly, preventing long-term property damage.
  • Construction & Roofing: Durable enough to handle the debris of a building site and the outdoor demands of clearing flat-roof runoff.
  • Warehouses & Factories: Perfect for maintaining large concrete floors and clearing wash-down areas after industrial shifts.
  • Workshops & Garages: Rapidly extracts oil, coolant, and water spills, keeping floor surfaces safe and compliant.

🛠️ Industrial Durability & Serviceability

Built in the UK to last a lifetime, the WVD1800DH is an investment in maximum uptime and low maintenance costs.

  • Full Accessory Kit (BS7): Supplied with a professional 38mm stainless steel tube set and a wide-track ProFlo wet pick-up nozzle for edge-to-edge efficiency.
  • Site-Ready Mobility: Mounted on a robust tubular steel chassis with giant non-marking rear wheels and heavy-duty front castors for easy transit across uneven floors.
  • Simple Maintenance: Features an easy-access head design and a tool-free brush/filter check system to keep the machine operational 24/7.
