Restrooms may not be the most glamorous frontier for robotics, but they are among the most revealing. In malls, airports, hospitals and office towers, they sit at the intersection of hygiene expectations, labour shortages and operational cost pressures. For facilities managers, they are also one of the hardest spaces to keep consistently clean.
Singapore-based Hivebotics is betting that this is precisely where robotics can prove its commercial worth.

The company has raised US$6 million in a Series A round led by Vertex Ventures Southeast Asia & India, with participation from Fareast Land Development, part of Farglory Group, and Rigel, an Asian manufacturer of smart and eco-friendly restroom products.
The funding will move Hivebotics’s flagship robot, Abluo, from pilot deployments into volume production. It will also support the expansion of the company’s distributor network across Asia, Europe, the Middle East, and North America, in addition to further develop HiveIntelligence, its software layer that plans, monitors, and verifies cleaning jobs.
Founded in 2021 out of the National University of Singapore by Rishab Patwari and Nguyen Tuan Dung, Hivebotics has spent the past year testing Abluo in more than 20 sites, including hospitals, airport terminals, and shopping malls. The robot has logged close to 10,000 operating hours across 12 months of deployment.
Why restrooms are a serious automation problem
Most cleaning robots in commercial buildings focus on floors. That is useful, but limited. Restrooms are far more complicated: they are wet, cramped, uneven environments filled with fixtures, cubicles, pipes, mirrors, and human traffic. Cleaning them involves more than moving in straight lines across open space.
Abluo is designed to clean a commercial restroom end to end, covering toilets, urinals, sinks and floors. The machine uses a mobile base and an articulated arm to reach around fixtures and under rims. Instead of brushes or cloths, which can transfer dirt and bacteria between cubicles, it relies on high-pressure steam, a targeted chemical jet, vacuum extraction and blow-drying.
The company says the system replaces around 30 minutes of manual work with a five-minute human inspection. That framing matters. Hivebotics is not pitching Abluo as a fully invisible robot worker, but as a way to reduce the most repetitive, unpleasant and labour-intensive part of restroom cleaning while keeping people in the loop for checks and exceptions.
Onboard vision allows the robot to identify fixtures. Its AI system then generates a cleaning route in real time. Each job ends with a scored before-and-after check, giving building operators a record of what was cleaned and to what standard.

That audit trail could become an important selling point. In facilities management, cleanliness is often judged by complaints, spot checks or subjective inspection. If robots can produce verifiable cleaning records, operators may be able to manage hygiene more like a measurable service level rather than a best-effort routine.
A labour crunch with regional relevance
The market Hivebotics is targeting is large, but the more immediate driver is labour. Soft facilities management, which includes cleaning, security, catering and related building 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.
Within that broader market, restroom cleaning is among the most difficult jobs to staff and retain. Kimberly-Clark has reported annual janitorial turnover of 200 to 400 per cent, a figure that reflects how physically demanding and often undesirable the work can be.
That pressure is especially visible in developed Asian markets such as Singapore, Japan, South Korea and parts of the Gulf, where ageing workforces and tighter labour supply are reshaping service industries. In Singapore, cleaning wages have also been rising under structured wage policies, adding pressure on building owners and contractors to improve productivity rather than simply hire more workers.
For Southeast Asia, the picture is more mixed. Labour costs remain lower in some markets, but major cities are dealing with higher hygiene expectations in airports, hospitals, retail centres and transport hubs. The pandemic also made visible something facilities operators already knew: cleanliness is not just a back-office function, but part of public trust.
“Within three years, teams of robots will do most of the repetitive, labour-intensive work of running a facility,” said Hivebotics co-founder and CEO Rishab Patwari. “We started with restrooms because they are the hardest: wet, cramped, and full of moving parts. Solve that, and the rest of the building follows.”
The ambition is broader than toilets. Hivebotics sees restrooms as a proving ground for what the robotics industry increasingly calls “physical AI”, systems that do not merely process information, but perceive and act in messy real-world environments. For years, robots have performed well in controlled settings such as factories and warehouses. Buildings, by contrast, are less predictable.
The competitive field
Hivebotics is entering a robotics market that has grown more crowded over the past decade. Companies such as Avidbots, Tennant, Gaussian Robotics, Pudu Robotics, SoftBank Robotics, and Singapore-based LionsBot have built machines for floor scrubbing, vacuuming and commercial cleaning tasks. Many are already selling into airports, malls, offices and industrial facilities.
The distinction Hivebotics is trying to draw is depth rather than breadth. While floor-cleaning robots are increasingly familiar in commercial buildings, restroom-specific automation remains a tougher category because of the need to manipulate fixtures, apply different cleaning methods and work in confined spaces. If Abluo can perform reliably across diverse layouts, the company may occupy a more specialised niche than broader cleaning robot makers. The trade-off is that niche hardware can be harder to scale: every new building type, fixture design and operating environment introduces complexity.
From pilots to production
The Series A round suggests investors believe Hivebotics has moved beyond the technical demonstration stage. Vertex Ventures Southeast Asia & India, which has backed companies such as Grab, Nium, FirstCry and PatSnap, is positioning the investment around labour scarcity and non-discretionary demand.
“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.”
The next test will be commercial rather than technical. Robots in facilities management must survive long deployment cycles, conservative procurement processes and demanding service expectations. A machine that works in a pilot still has to prove it can be maintained, supported and justified financially across hundreds of sites.

Hivebotics has strengthened its commercial bench for that phase. Vincent Sim, formerly head of Kärcher’s Singapore business, joined the company as Chief Sales Officer in 2025, bringing experience from one of the best-known names in cleaning equipment.
For Singapore’s startup ecosystem, Hivebotics also reflects a broader shift. The city-state has long pushed robotics adoption in public services, logistics and built environments, but hardware companies often face a harder fundraising road than software startups. They need capital for manufacturing, field support and inventory before revenue scales.
If Hivebotics can turn restroom cleaning into a repeatable, exportable robotics category, it will show that Southeast Asian hardware startups can compete in global industrial automation from highly specific starting points. The company’s bet is simple: solve the job few people want to do, in the room every building needs to maintain, and the market will listen.
