Combi - handwashing station - Fully automatic handwashing station consisting of water soap and air are mixed optimally: ensuring extreme hygiene, whilst saving water and soap.

Washing your hands with Smixin uses 90% less water and 60% less soap compared to a normal hand washing cycle. The Product Combi is a unique 3-in-1 hand washing system designed to be used inside or outside the washroom. Water, soap, and paper are dispensed optimally and the system is connected to an external monitoring platform. Hygiene levels after washing your hands with Smixin (12-15 seconds) are comparable with washing your hands for a full recommended WHO guideline with a normal faucet and soap dispenser (30-60 seconds) – as confirmed by a leading testing institute.
