Inside GILAS: how a glass gets clean in about a minute
Press a button for water; return the glass and a biodegradable spray, 40 kHz ultrasound and 254 nm UV-C light get it ready for the next person. Here’s how, and what we’re still validating.

GILAS does two jobs in one unit. Press a button and it fills a sanitised steel glass with drinking water, without anyone touching a tap.
When the glass comes back, three cleaning stages run automatically, one after another. No staff and no sink are involved.
Stage 1: Eco-solution spray
High-pressure nozzles spray a biodegradable alkaline solution (pH 9.5–10.5) that dissolves sugars and organic residue, emulsifies oils and loosens mineral deposits.
Stage 2: Ultrasonic cleaning
40 kHz piezoelectric transducers create millions of microscopic cavitation bubbles that implode against the glass, lifting residue and biofilm from surfaces a spray can’t reach.
Stage 3: UV-C disinfection
254 nm UV-C lamps around a reflective chamber expose every surface of the glass, disrupting the DNA and RNA of microbes. The lamps switch on only after the rinse, which is designed to cut power use.
No plumbing needed
In the portable variant, drinking water, cleaning solution and wastewater are held in sealed tanks, so GILAS needs nothing but a wall socket. That’s what lets it sit at a school water point or beside a wedding counter. Other variants can connect to an existing drinking-water supply.
