Have you put water in the blue container?

I don't know. I would ask Dyson directly.

The appliance is suitable for all types of hard floors, including sensitive parquet (wooden floors). It is specially designed for hard floors such as parquet, linoleum, tiles, vinyl and laminate and cleans both wet and dry dirt gently and effectively.

Cleaning agents are not required to use the Dyson WashG1. Clean water is all you need to effectively clean hard floors. The WashG1 is specially designed to work without additional detergents, making cleaning more hygienic and easier.

The brushes (rollers and dirt brush rollers) of the Dyson WashG1™ wet cleaner should be replaced depending on use. Here are some important points to note: - Replacing the rollers: The rollers should be replaced after about 6 months of use. The device warns you with a warning message and displays a QR code that you can use to order spare parts. - Replacing the dirt brush rollers: The dirt brush rollers should also be replaced regularly when they are worn out. The replacement instructions can be found in the operating instructions and on the Dyson website. If the brushes are not available, here are some steps you can take: - Check the delivery status: make sure you order the replacement parts through the official Dyson website or authorised dealers. - Contact customer service: If the spare parts are not available, contact Dyson customer service for further assistance and possible alternatives. - Maintenance and cleaning: Until replacement parts are available, you can clean the existing brushes regularly to prolong their life. Wash the rollers and dirt brush rollers in warm water and detergent and allow them to dry.

I don't know what the Italian sockets are like, but on the product I received there was only a Swiss socket.

You can't win them all ;)
