About Us

It started with a toddler on a clean floor.

In 2022, Sarah Mitchell was on her hands and knees scrubbing her Melbourne bathroom. Her 18-month-old daughter, Lily, was playing in the hallway — just metres away from the bleach spray Sarah had just used on the tiles.

She remembers thinking: "I've just made this floor spotless. And I'm terrified to let my daughter crawl on it."

It wasn't the first time she'd felt it — that quiet, nagging guilt that came with every clean. She'd tried switching to "natural" products, but the grout stayed grey. She'd tried eco sprays, but the stovetop stayed greasy. Every alternative felt like a compromise.

"I didn't want to choose between a genuinely clean home and a safe one for my kids. I wanted both. And I couldn't understand why that felt impossible."

A physiotherapist friend mentioned that hospitals had been using pressurised steam for surface sterilisation for years — killing bacteria as effectively as chemical disinfectants, with nothing but water. Sarah went looking for a home version that actually worked. What she found were either cheap, underpowered devices that disappointed — or commercial units that cost thousands.

So she decided to build what she couldn't find. Eighteen months of sourcing, testing, and refining later — SteamPure Pro was born. A 105°C, 1500W, 15-second-heat device purpose-built for Australian homes. Powerful enough to actually work. Safe enough that she'd let Lily crawl on a floor she'd just cleaned.

She named the brand Zennredi — a nod to the calm that comes from being ready. A home that's genuinely clean. A mum who's at peace with how she's cleaned it. Ready for whatever the day brings.

Our Mission. To make chemical-free the obvious choice.

The cleaning industry has spent decades convincing Australian families that powerful clean requires powerful chemicals. We're here to prove that's not true. Heat is more powerful than bleach. Water is more powerful than disinfectant. And your family deserves a home that's genuinely clean — not just chemically treated. Every product we build, every decision we make, is in service of that one belief.

The values behind everything we do.

  • 🌿Chemical-free isn't a compromise

    We reject the idea that you have to choose between a genuinely clean home and a safe one. 105°C steam cleans more thoroughly than bleach — and leaves absolutely nothing behind. Chemical-free isn't the weaker option. It's the smarter one.

  • 👨‍👩‍👧‍👦 Family first, always

    Every product decision we make starts with one question: would we be comfortable with a toddler on this floor five minutes after cleaning it? If the answer isn't an immediate yes, we go back to the drawing board. Your family's safety isn't a feature. It's the foundation.

  • AU Proudly Australian

    Zennredi was founded in Melbourne and built for Australian homes. We understand the Australian climate, the Australian home, and the Australian family. Our support team is local, our business is local, and we're committed to building a brand Australians can genuinely trust.

  • 🔬 Proof over promises

    We don't ask you to take our word for it. Every claim we make is backed by peer-reviewed, published research. Steam at 105°C has been clinically tested against bleach in hospital settings. The science is real. The results are real. We show you both.

  • 💚 Better for the planet

Built by a mum. For every mum.

Sarah spent twelve years working in healthcare operations before starting Zennredi. She is a mother of two — Lily (5) and James (3) — and a lifelong home-proud perfectionist who was never quite satisfied with the cleaning products available to her. After her hospital physiotherapist friend introduced her to the science of steam sterilisation, she spent eighteen months developing, testing, and refining SteamPure Pro in her own Melbourne home before launching it to the public.

She built Zennredi not because she saw a market opportunity — but because she genuinely needed the product and couldn't find it anywhere.

"I built the product I wished existed when Lily was a baby. I'm glad it exists now."
