Yes, R5 Floor is also suitable for use with robots and floor cleaners. Prepare the product as usual: pour the contents of a refill into a 750 ml bottle and add water. For use with a robot: follow your robot's instructions; if the use of detergents is permitted, use 6 ml of product per liter of water.

Yes. The home kits include the empty 750ml spray bottle and the concentrated refill. You buy the container once, then use only the refills.

No. Tap water is enough. It is not necessary to use filtered or purified water.

Our refills are formulated with 100% plant-based surfactants, produced by certified European suppliers. One of the surfactants is RSPO Mass Balance (Roundtable on Sustainable Palm Oil) certified, guaranteeing a controlled supply chain. The raw material supplier is certified according to the RSPO Supply Chain Certification standard (ICEA certificate no. 19/2024). The other surfactant is produced in France using an innovative process that utilizes waste from the cereal industry (wheat bran and straw). Its raw materials are approved according to the COSMOS v4 standard by the certifying body Ecocert Greenlife (certificate no. 115511). The ingredient contains no petrochemical components or non-natural ingredients.

Nickel is a metal that can be present in trace amounts in many common products, including cosmetics, detergents, and food. It is one of the most common causes of allergic contact dermatitis (about 10-15% of the European population is sensitive to nickel). To meet the needs of nickel-sensitive people, we subject some of our products to a specific analytical test to determine the nickel content. How the test was performed: Method: ICP-MS (Inductively Coupled Plasma Mass Spectrometry) Reference standard: EPA 6020B:2014 Laboratory: Innovhub SSI (Milan) — independent external laboratory Limit of Quantification (LOQ): 0.1 mg/kg What the result "< 0.1 mg/kg" (equal to <0.1 ppm) means: The value reported indicates that any nickel present in the product is below the instrument's limit of quantification (0.1 mg/kg, equal to 0.1 parts per million). ICP-MS is the most sensitive analytical technique available for the determination of trace metals. Technical note: there is currently no specific legal limit for nickel in detergents (EC Reg. 648/2004) or cosmetics (EC Reg. 1223/2009, Annex III) in Europe, but dermatological literature and associations for nickel-sensitive individuals suggest indicative thresholds between 1 and 5 mg/kg for safe products. The value found in our tested products is 10 to 50 times lower than these thresholds. The full test report is available upon request.

With the R5 refill system, you eliminate the repeated purchase of single-use bottles by reusing the same container over and over again.
