Setup
Getting Started
- Unpacking: Carefully remove all components from the packaging. Retain packaging for future storage or transport.
- Filling the Water Tank: Ensure the unit is unplugged. Unscrew the water tank cap. Using the provided measuring cup and funnel, fill the tank with up to 1.15 liters of regular tap water. Do not overfill. Securely replace the cap.
- Connecting Accessories: Attach the desired accessory (e.g., hose, extension tubes, floor tool) by aligning the connectors and twisting until secure.
- Powering On: Plug the power cord into a grounded electrical outlet. Turn the unit ON. The indicator light will illuminate, signaling that the unit is heating. Allow approximately 15-20 minutes for the water to heat and steam pressure to build. The ready indicator light will turn on when the unit is ready for use.
Operating Instructions
The Dupray One Steam Cleaner provides up to 50 minutes of continuous steam cleaning per fill-up. It features adjustable steam pressure directly on the hose for precise control.

Adjust steam pressure directly on the hose for optimal cleaning.
Cleaning Different Surfaces
Always test a small, inconspicuous area before cleaning the entire surface to ensure compatibility.
Floors and Grout

The Dupray One Steam Cleaner effectively cleans floors and grout lines.
Attach the floor tool with a mop pad. For general floor cleaning, move the tool slowly and evenly across the surface. For stubborn grout lines, use the grout brush attachment with short, concentrated bursts of steam.
Kitchens and Ovens

The steam cleaner is effective for deep cleaning ovens and kitchen surfaces.
Use the nozzle or a small brush attachment for countertops, sinks, and stovetops. For ovens, direct steam onto baked-on grease and grime, then wipe away with a cloth. The high temperature helps to loosen tough residues.
Furniture and Mattresses
Attach the fabric tool with a towel sleeve. Move the tool slowly over upholstery and mattresses to sanitize and refresh. The steam helps to kill dust mites and bacteria. Ensure fabrics are suitable for steam cleaning and allow to air dry completely.
Car Interiors
Utilize the small brush attachments or nozzle for car seats, carpets, and dashboards. Steam can help remove stains and odors from fabric surfaces and sanitize hard surfaces.
Windows and Mirrors
Attach the squeegee tool. Apply steam to the glass surface, then use the squeegee to wipe away moisture and dirt for a streak-free finish. Work from top to bottom.
Maintenance
Care and Storage
- Draining Water: After each use, ensure the unit has cooled down completely. Carefully unscrew the water tank cap and drain any remaining water. This prevents mineral buildup.
- Cleaning the Unit: Wipe down the exterior of the steam cleaner with a damp cloth. Clean accessories as needed. Mop pads and towel sleeves can be machine washed.
- Descaling (if necessary): If you notice reduced steam output or mineral buildup, consult the full user manual for descaling instructions.
- Storage: Wrap the power cord neatly around the designated posts on the unit. Store the steam cleaner and all accessories in a cool, dry place, away from direct sunlight and extreme temperatures.

The power cord can be neatly wrapped for compact storage.
