LESSEAU® Solid Hand Wash Solution Wins Hygiene Solution Innovation of the Year; TASKI ULTIMAXX 360 Recognized as Category Honoree for Automation & Equipment Innovation
WILMINGTON, Del. (USA) — Diversey, a Solenis company and global leader in hygiene, infection prevention and cleaning solutions, earned two major recognitions at the 2025 Innovative Leaders Award Program during ISSA Show North America. LESSEAU®, the solid hand wash technology brought to you through a partnership between Diversey and Slimstones B.V., while the TASKI ULTIMAXX 360 automatic cleaning machine was recognized as an honoree in the automation and equipment innovation category.
The awards, presented at the Innovation Showcase & Theatre on the ISSA expo floor, highlight breakthrough technologies that enhance cleaning performance, sustainability and operational efficiency across commercial, institutional and residential environments.
LESSEAU’s win underscores the growing market demand for environmentally responsible hygiene solutions. The solid hand wash platform eliminates plastic packaging and reduces transportation emissions by replacing traditional liquid soaps with compact, water-efficient solid formulations.
Honored for pioneering a new class of compact mechanized cleaning, the TASKI ULTIMAXX 360 replaces manual mopping with 5× better soil removal, immediate drying and cutting-edge technologies. Built with recycled plastics, IntelliBac antimicrobial protection and energy-saving digital motors, it brings professional hygiene, agility and sustainability into the tightest spaces.
“These two recognitions highlight the strength of our innovation pipeline across institutional solutions,” said Gaetano Redaelli, executive vice president of institutional solutions, Solenis. “LESSEAU shows what’s possible when sustainability and user experience are designed together. At the same time, the recognition of the TASKI ULTIMAXX 360 reflects our commitment to developing smarter, more efficient technologies that elevate cleaning standards for customers worldwide.”
Winners and honorees were selected by a panel of industry executives and experts from leading sector organizations. Entries were evaluated on innovation, usability, environmental impact and their ability to address key operational challenges.
