A Robot for the Hardest Room in the Building: Inside Hivebotics' $6M Series A

One of the most stubborn problems in commercial real estate is not glamorous: somebody has to clean the restrooms, and increasingly, nobody wants to. On September 4, Singapore-based Hivebotics closed a US$6 million Series A — led by Vertex Ventures Southeast Asia & India, with participation from Fareast Land Development (Farglory Group) and Rigel, an Asian manufacturer of eco-friendly smart restroom products — to take its restroom-cleaning robot Abluo from pilot deployments into volume production.

The round funds three things: manufacturing Abluo at scale, expanding the distributor network across the company’s four core markets, and further development of HiveIntelligence, the proprietary “physical AI” layer that plans, monitors and validates every cleaning job the robot runs.

Why restrooms are the wedge

Most commercial cleaning robots on the market today are floor scrubbers. They handle the open, flat, predictable parts of a building and stop at the first doorframe. Abluo is a mobile manipulator — a wheeled base carrying an articulated arm — that cleans a commercial restroom end to end: toilets, urinals, sinks, and floors, not the floor alone.

Hivebotics’ founding logic is that restrooms are the hardest case in facilities management. “We started with restrooms because they are the hardest: wet, cramped, and full of moving parts,” said Rishab Patwari, co-founder and CEO. “Solve that, and the rest of the building follows.”

The economics are driven by a labour market that keeps tightening. Soft facilities management — cleaning, security, catering and related services — was estimated at US$770 billion globally in 2024 and is projected to reach US$1.23 trillion by 2033, according to Grand View Research figures cited by the company. Restroom cleaning is its most labour-intensive line, and among the hardest to staff: Kimberly-Clark has reported janitorial turnover of 200 to 400 per cent annually.

“Restroom cleaning is one of the few labour markets where demand is non-discretionary and supply keeps tightening,” said Chan Yip Pang, Executive Director, Investment at Vertex Ventures Southeast Asia & India. “In Hivebotics’ key markets, the cleaning workforce is ageing and wage floors are rising, so operators need a way to hold hygiene standards without adding headcount they cannot find.”

How Abluo works

Abluo cleans without contact. Rather than brushes or cloths — which carry cross-contamination risk between cubicles — it combines high-pressure steam, a targeted chemical jet, vacuum extraction, and a blow-drying stage, delivered by an arm that reaches under rims and around fixtures.

Three technical choices stand out:

• Contactless cleaning. Steam and vacuum instead of wiping surfaces means no shared cloth moving microbes between stalls, and no consumables to restock beyond water and chemical concentrate.
• Onboard vision with real-time route generation. Onboard cameras identify each fixture, and a proprietary AI pipeline generates the cleaning route in real time rather than following a fixed map — necessary in rooms where layout, occupancy and soil conditions change constantly.
• Auditable outcomes. Every job ends with a scored before-and-after check, so cleaning quality can be verified rather than assumed — the kind of paper trail that matters in hospitals and airports, where hygiene compliance is regulated.

Under the hood, the arm’s motion planning runs on MoveIt Pro, the commercial robotics platform from PickNik Robotics built on the open-source MoveIt project. According to PickNik’s published case study, Hivebotics’ hardest engineering problem was planning consistent, intuitive motions when the robot’s base was parked imperfectly in cramped stalls. PickNik’s customization of MoveIt Pro’s path planning and the addition of detailed real-time simulation reportedly saved an estimated 10 months of product development time.

From pilot to production

Abluo is not a lab prototype. The robot has logged nearly 10,000 operating hours over 12 months of use across more than 20 sites in Asia, Europe, the Middle East and North America, including hospitals, airport terminals and shopping malls. The company says Abluo cleans a restroom to the same standard every cycle, replacing around 30 minutes of manual work with a five-minute human inspection.

Hivebotics was founded in 2021 out of the National University of Singapore by Rishab Patwari and Nguyen Tuan Dung, and traces its origins to a blunt piece of customer development: the founders applied for work attachments with cleaning service providers at NUS, malls and hotels in 2023 to learn the job from the inside before designing for it. Vincent Sim, formerly head of Kärcher’s Singapore business, joined as Chief Sales Officer in 2025 — a hire that signals the company’s sales motion is now aimed at professional cleaning contractors and facility operators rather than technology buyers.

The physical AI thesis

Patwari’s framing of where this goes is aggressive: “Within three years, teams of robots will do most of the repetitive, labour-intensive work of running a facility… The timing is right. Labour is scarce, physical AI is breaking through, and hardware is getting cheap. Robots are no longer productivity tools. They are essential services.”

That thesis — janitorial robotics as essential infrastructure rather than a cost-cutting gadget — is what makes a $6M Series A worth watching. The counter-arguments are familiar: robotics hardware is capital-intensive, sales cycles in facilities management are long, and incumbents like Kärcher have distribution networks that startups envy. But Hivebotics’ data point cuts the other way: its strategic round participants include a Taiwanese land developer (Farglory) and a smart-restroom hardware manufacturer (Rigel) — in effect, the robot’s future customers and channel partners buying equity in it.

Whether Abluo becomes the Roomba of commercial restrooms or a niche airport product, the $6M round is a small but concrete signal that “physical AI” investment is broadening beyond humanoid demos and into the unglamorous, high-turnover work that actually keeps buildings running.
