Hivebotics' restroom-cleaning robot bet: US$6M Series A after 10,000 hours
NUS spinoff Hivebotics bets facilities operators will pay a robot to clean whole restrooms; Abluo hit 20+ sites, then a US$6M Vertex-led Series A.
Hivebotics
What the business is
Hivebotics builds Abluo, a mobile robot with an articulated arm that autonomously cleans commercial restrooms — toilets, urinals, sinks and floors — for malls, airports, hospitals and other facilities.
Starting capital：US$6 million Series A (September 2026), led by Vertex Ventures Southeast Asia & India with Fareast Land Development (part of Taiwan's Farglory Group) and smart-restroom maker Rigel.
How it started
During the COVID-19 pandemic, a cleaning-company operator told the founders his crews could not cope with restroom workloads. Convinced existing robots were useless in tight bathrooms, Rishab Patwari (computer engineering) and Nguyen Tuan Dung (mechanical engineering) spent days cleaning toilets and mixing solvents themselves. The pair built Hivebotics in 2021 as a spin-off from the National University of Singapore, developing it through NUS programs including the Innovation and Design Programme, the EDIC Entrepreneur Fellowship, NUS Overseas Colleges and the Graduate Research Innovation Programme.
What happened
Abluo launched commercially in 2024. Over its first 12 months it recorded nearly 10,000 operating hours across more than 20 sites in four regions — hospitals, airport terminals and shopping malls — cleaning to the same standard each cycle and replacing about 30 minutes of manual work with a five-minute human inspection. In September 2026 the company closed a US$6 million Series A led by Vertex Ventures Southeast Asia & India to fund volume production, expand its distributor network across four core markets and develop HiveIntelligence, its proprietary AI software layer.
How it ended up
Still running and scaling: as of September 2026 Hivebotics was moving Abluo from pilot deployments to volume production and expanding internationally, with a stated five-to-ten-year ambition of becoming an autonomous facilities-management provider running whole buildings from a remote command centre.
Background
Hivebotics bet that the way into facilities automation was the task nobody wanted: cleaning commercial restrooms. Founded in 2021 as a National University of Singapore spin-off by Rishab Patwari and Nguyen Tuan Dung, the company started from a cleaning operator's pandemic-era plea that his crews could not keep up — and from the founders' own days scrubbing toilets and mixing solvents to understand the job.
Its robot, Abluo, goes beyond floor-scrubbing machines by cleaning a whole restroom: toilets, urinals, sinks and floors, using non-contact high-pressure steam, a targeted chemical jet, vacuum extraction and blow-drying, with onboard cameras and real-time route planning. Launched commercially in 2024, Abluo logged nearly 10,000 operating hours in 12 months across more than 20 sites in Asia, Europe, the Middle East and North America, replacing about 30 minutes of manual work with a five-minute human inspection.
In September 2026 the company closed a US$6 million Series A led by Vertex Ventures Southeast Asia & India, with Fareast Land Development (Farglory Group) and smart-restroom maker Rigel joining. Vertex framed the demand as non-discretionary: cleaning cannot be deferred, while workforces age and wage floors rise. The capital funds volume production of Abluo, distributor expansion across four core markets and HiveIntelligence, the AI layer Hivebotics plans to extend far beyond bathrooms.
What has to be true
- Hivebotics chose the most avoided chore — commercial restroom cleaning — and made full-room automation the product, where floor-only robots had left a visible gap.
- The origin was grounded in a real operator's problem: a cleaning company unable to staff restrooms during COVID, which the founders validated by doing the work themselves.
- Cleaning is non-discretionary spending, so demand is resilient even as labour shortages and wage floors push operators toward automation.
- It raised a Series A on demonstrated product evidence — 10,000 operating hours across 20+ sites in four regions — rather than on pilots and promises.
What can be applied
Pick the task humans will not do — the dirtiest, least-staffable corner of a market — and automate the whole job, not the easy part; the product evidence then raises the money.
Aftermath
As of September 4, 2026, Hivebotics had closed its US$6 million Series A and was shifting Abluo from pilot deployments to volume production, widening its distributor network across four core markets and developing HiveIntelligence, its proprietary physical-AI software layer. The company's stated five-to-ten-year plan is to become an autonomous facilities-management provider: an ecosystem of integrated robots, including robots from other manufacturers, managing entire buildings from a remote command centre, with cleaning as the first pillar.
