Introduction
Using only water, a steam mop will clean your household floors without the need for harmful or toxic chemicals, leaving you with peace of mind that your family's wellbeing is taken care of.
In addition to this, steam mopping cleans and dries the flooring simultaneously, providing a nicer finish on smooth or shiny flooring as it ensures that streaks or marks aren't left behind.
Steam cleaning with the STM15 steam mop will bring a completely new level of cleanliness to your home. From the kitchen to bathroom, this lightweight steam mop will take care of the hard cleaning work so that you don't have to.
It is ideal for cleaning hard floors such as sealed wood, lino or tiles. Thanks to its simplistic design, it is easy to manoeuver along every edge and corner, blitzing away bacteria, dirt and scum along the way, leaving you with beautifully clean floors.
DURONIC
Before First Use
- Remove all of the packaging materials. Check that there are no parts missing.
- Assemble the steam mop following the steps below.
IMPORTANT:
- This steam mop operates by emitting steam at an increased temperature of 100^ C.
• Always test on an inconspicuous area of the floor first. - Never use it on flooring which cannot resist this temperature, or on floorings with coatings, polishes, or that are plastic or antique.
- If in any doubt, please check carefully on a part of the floor surface where minor marks will not matter.

Place the mop on the carpet and move it slowly back and forth, allowing the steam to penetrate the fibers. Avoid leaving the mop in one spot for too long.
Please Note:
• Not suitable for wool carpets or rugs.
- Not suitable for delicate, antique, or non-colorfast rugs.
DURONIC
How to Use
- Before using the steam mop, ensure that the floors are swept or vacuumed to remove any surface dirt or debris.
Note:
We recommend to not use the steam mop on bare wooden floors, unsealed flooring or on any surfaces where wood is exposed (as it will absorb moisture and may distort).
- Attach a mop pad to the mop head by aligning the hook & loop pads.
- Pull the water tank upwards to release the water tank from the main unit.
- Remove the cap from the tank, fill the tank with deionised or distilled water. Fill up to 500ml. Close the cap on the water tank.
- Place the water tank back into the main unit and ensure that it clicks into place as this means the tank is securely back in the right place.
Note:
If you are using this mop for the first time, or for the first time after a period of not using it, you will need to wait a minute or two for the water to start traversing through into the main unit.
- Unwind the power cable from the cable management hooks. A quick way to release the cable is to rotate the top cable management hook inwards as this automatically releases the whole cable at the same time.
- Plug in the power cable to a mains outlet. On the mop main unit, press the power button. The power indicator light will light up and the unit will start to preheat.
DURONIC
How to Use
- When the preheating is done, the light will turn green. The water pump will start working and you will start to see steam start to come out of the mop head.
- Push and glide the mop over the floor surface to clean it. Try to use up all the water in the tank at one time. Do not use the mop just in one place, or on the same place over and over again. Depending on the material of the floor, it may deform or fade it over time. If there is any water left in the water tank, empty the remaining.
- After you have finished mopping, press the power button to switch the mop off.
- Unplug the power cable from the mains outlet socket and wind it around the cable management hooks to secure in place.
Using on Carpets
With the mop cap attachment fitted, the steam mop can be used to refresh and sanitize carpets and rugs. Place the mop on the carpet and move it slowly back and forth, allowing the steam to penetrate the fibers. Avoid leaving the mop in one spot for too long.
Suitable Carpets:
- Low-pile and medium-pile carpets
- Most rugs that can tolerate heat and moisture
Unsuitable Carpets:
• High-pile or shag carpets
- Wool carpets or rugs
• Delicate, antique, or non-colorfast rugs
- Carpets made of materials sensitive to heat or water
Always check the carpet manufacturer's cleaning instructions before use.
DURONIC
Cleaning and Maintenance
Before cleaning, turn off the steam mop and allow it to cool down completely.
To clean the main unit, use a dry cloth to remove any dust or dirt. If there are stubborn areas of dirt, use a damp well-wrung cloth to wipe over the body.
Leave to air dry or use a dry cloth afterwards to dry it.
IMPORTANT:
- Do not immerse the power cable, plug or the mop itself into water or any liquid.
- Do not pour water or any liquid over the mop.
- Do not use detergents, abrasive cleaning products or any kind of cleaning solutions in the water tank as this may damage the mop.
- Do not use alcohol or solvent-based cleaners on the plastic components, as this will cause the cracking and ageing of these parts.
Cleaning the Mop Pads
Please wash the mop pads immediately after use. The mop pads should be cleaned separately from other fabrics. Machine or hand wash and air dry naturally. Lay flat to dry.
The mop pads can be machine washed at 40^ C max. For heavy soiling, soak the mop pads in warm water and detergent or a mild stain remover, then wash as normal in the washing machine.
IMPORTANT:
- Do not use bleach or fabric softener when cleaning the mop pads.
Each mop pad can be used 70 to 80 times under normal circumstances.
When the mop pad appears damaged or the cleaning effect is weakened, it is recommended to replace the it with a new mop pad.
DURONIC
Cleaning and Maintenance
Decalcifying the Water Tank
To clean calcium deposits that build up inside the Water Tank;
- Remove the water tank from the steamer.
- Add one or two tablespoons of white vinegar to a full Water Tank. Close the Water Tank Cap and shake the contents.
- Rinse out the water tank with clean water when clean.
WARNING:
- Do not turn the steam mop on when the water tank is removed or being cleaned.
Removing Internal Limescale
If your steam mop produces steam more slowly than usual or stops producing steam, limescale may have built up inside. Limescale forms on internal metal parts over time and can reduce performance.
To keep your steam mop working properly, remove limescale regularly every 25-50 full tanks of water or at least once a month, especially in hard water areas.
- Mix a solution of 1/3 white vinegar and 2/3 tap water.
- Pour the solution into the water tank.
- Place the mop in a secure position so the steam is directed away from the floor, furniture, or other surfaces.
- Plug in the unit and switch it ON. Allow it to run until the vinegar solution is completely used up.
- Repeat the process if needed until steam flow returns to normal.
- Empty the tank, rinse thoroughly, and refill with fresh water.
- Run the mop again with only fresh water until the tank is empty, to flush out any remaining vinegar.
DURONIC
Cleaning and Maintenance
Cleaning Blocked Accessories
In some areas, tap water has a high mineral content. This can cause calcium buildup inside the nozzle, reducing the amount of steam that comes out of the handheld accessories.
Wipe the water outlets with a damp cloth. If that does not clear the debris;
- Spray a small amount of spray lubricant (1–2 bursts) into the tip of the Jet Nozzle.
- Fill the steamer with water as instructed in the manual.
- Run a continuous jet of steam through the blocked accessory for several minutes to ush out the deposit.
- Once steam ows freely, aim the nozzle at a neutral surface or a cleaning cloth to ensure no debris is released.
Storage
Let the steam mop cool completely before storing.
Store in a cool dry place.
Position the mop in such a way that it is rested against something stable, like a wall, ensuring that it will not fall at any time.
Remove the mop pads from the mop before storing it away.
Ensure the power cable is wrapped around the cable management hooks with the upper hook facing upwards so that it is securely holding the cable in place.
DURONIC
Troubleshooting
| Problem Possible Cause and Solution | |
| The mop won’t start | Check the mains power outlet, the fuse on the plug and if the switch is pressed on or off. |
| There is no steam coming out | Check the water level in the water tank.Check if the steam holes are blocked. If they are, clean the blocked holes with a damp cloth. |
| There is a lot of moisture after use | The mop pad is either too wet or installed incorrectly. Remove it, wring it out and place it back onto the mop head. |
| It is difficult to move whilst in use | The mop pad may be too dirty. Wash and wring out the pad before continuing to use it. Alternatively, change the mop pad for a new one. |
| The mop pad is too dry. Allow the steam to pass through it for a short while to dampen it before attempting to use it again. | |
If you are still experiencing issues, please contact Duronic.
