Proper use
The steam cleaner is only designed for removing dirt with water vapor. For example, it is suitable for cleaning the following areas: smooth surfaces (e.g. work areas, tiles, glazed tiles, windows or mirrors), hard-to-reach areas (e.g. corners, grouting, blinds, WC, fittings), and textiles (e.g. curtains, cushions, articles of clothing and car seats).
The steam cleaner is only intended for private use and is not suitable for commercial purposes. The steam cleaner is not intended for use outdoors or for use with liquids other than water. Only use the steam cleaner as described in this user manual. Any other use is deemed improper and may result in damage to property or even personal injury.
The steam cleaner is not a children’s toy. The manufacturer or vendor accepts no liability for damage caused by improper or incorrect use.

Attention:

− Let the accessories used cool off first before you remove them.
− Do not use the steam cleaner if it has fallen down, if there are any apparent damages or if it is leaky.
− Keep the steam cleaner away from children if it is switched on or is cooling down.
− Wear gloves, protective goggles, and respiratory protection when attempting to remove substances that are harmful to health.
− Do not point the steam jet at other persons or animals. Hot steam can cause serious injury!
− First, check an inconspicuous area as to whether the material you intend to clean is suitable for cleaning with a steam cleaner e.g.:

Steam could cause lacquered wood or leather to fade.
Unprotected wood could swell up.
The steam could remove protective layers of wax.
Plastics could tint if exposed to steam.
Soft plastics could deform if exposed to steam.
Cold glass or mirror surfaces could burst if exposed to hot steam.

− If you would like to clean windows, you must first warm them up, e.g. by applying steam to a larger area at a greater distance and then from a closer distance.
− Acrylic, velvet and satin are sensitive to hot steam as are plastic fibers.
− Ensure that the main cord does not come into contact with hot parts.
− Never expose the steam cleaner to high temperatures (heaters etc.) or to effects of the weather (rain etc.).
− Never fill the steam cleaner with liquids other than water.
− Never immerse the steam cleaner in water to clean it and do not use a steam cleaner to clean it. Otherwise, the steam cleaner could be damaged.
− Do not in any case place the steam cleaner or the individual parts in the dishwasher. It would be destroyed. Checking the steam cleaner and package contents 13
− Stop using the steam cleaner if its plastic parts exhibit cracks or breaks or are deformed. Only replace damaged parts with corresponding original spare parts.
− Do not operate the steam cleaner with an empty tank. Once the water reservoir has been used up, pull the mains plug to avoid overheating it.

Operation:

Put the steam cleaner on the platform and open the safety cap.
Use the measuring cup to fill the water. The maximum volume is 400ML. We suggest you only fill water 300-350ML to get the dry steam. If more than 350ml water, there may some water in the steam at the first 2 minutes.

Special attention:

Please use clean water (small solid particles may block pipe or make machine failure)
Please do not pour any chemicals such as alcohol, cleaning agents into the steam cleaner. (some chemical solvents can easily cause machine failure, and even endanger the user’s personal safety in serious cases)
If the tap water in your area is very hard, it is recommended that you mix the tap water with distilled water. Otherwise, the steam cleaner could calcify prematurely and clog the steam nozzle.
Please do not add water less than 150ml.
3. Close the safety cap anticlockwise.
4:Insert the mains plug into the socket, the red light will light up indicating heating.
As soon as the steam cleaner is operational, the green indicator light will be on. The red indicator light will be on/off during usage.
Attention:
− Only use the product once the green indicator light is On for the first time. Otherwise, hot water drips or sprays.
5. Turn the children’s lock to the “on” position, then press the steam trigger. Steam will be released directly. Remember you should always press the steam trigger. Once you released the steam trigger, the child’s lock will turn back to the “OFF” position auto, and steam stopped.
Attention: Without pressing the child’s lock, there is no use to steam the trigger.
If there is no more water in the water tank, no more steam will be emitted when you push the steam trigger .The water must be refilled as follows:
1. Pull the main plug out of the socket.
2. Push the steam trigger until no more steam is escaping.
3. Wait for cooling at least 12-18 minutes.
4. Slowly unscrew the safety cap and wait a few seconds
5. Slowly refill the water tank with water.
6. Close the safety cap again.

If the tap water in your area is very hard, it is recommended that you mix the tap water with distilled water. Otherwise, the steam cleaner could calcify prematurely and clog the steam nozzle.
6. After usage, please turn the power off, release all the residual steam and wait for the machine to cool down.
The steam cleaner has to overheat protection. It will automatically switch off if it overheats (e.g. when the water tank is empty).
Instructions of accessories:

1: Extension hose
If the steam cleaner is hard to reach the cleaning area, it can be used with an extension hose. The operation method is as follows: connect the end of the hose to the steam outlet until hearing a clicking sound.

2: Big nozzle
The big nozzle can be used to clean the corners easily by connecting with a steam outlet like an extension hose.

3: Glass brush
Insert the big nozzle into the notch of the glass brush (below picture 1), and turn it clockwise until it clicks (below picture. 2). After use, take out the glass brush by turning it anti-clockwise. For cleaning desk and chair, bookcase, or ironing clothes, put a white towel into the glass brush.

4: Nylon and stainless brush
Insert the big nozzle into the notch of the round brush (below picture 1), and turn it clockwise until it clicks (below picture. 2). After use, take out the round brush by turning it anti-clockwise.

5: Extension tube
If the steam cleaner is hard to reach some cleaning areas or is used to clean floor and glass in a high place, it can be used with an extension tube. The operation method as follows: connect the end of the extension tube to the steam outlet until the fixed lock is fully buckled into the hole of the extension tube, and hear a sound of clicking means installation completed.

6: Floor brush (floor brush towel)
When cleaning the floor, connect two or three extension tubes together to the steam machine. The other end of the extension tube is installed with a floor brush. The extension tube directly connects to the connector of the floor brush, open the clips on the two sides of the floor brush and fix the towel.

Steam temperature:
The below data is for users’ reference, we can adjust the operation method in order to reach better cleaning performance.

Attention: The above data are measured by the laboratory, and there will be a little deviation in practice.

Cleaning:

Before cleaning, pull the mains plug out of the socket.
Let the steam cleaner cool off completely.
Wipe the steam cleaner and the accessories off with a damp cloth. Then let all parts dry completely.

Storage:
All parts must be completely dry before being stored.
− Always store the steam cleaner in a dry, clean, and dust-free place.
