One year ago, we demonstrated it. Today, Singapore is talking about it.
On 12 November 2025, our Singapore head office, Uni-Corp Singapore, showed PUB, Singapore’s national water agency, the Dotek rover at Pandan Garden: a remote-controlled, amphibious flood water pump on tracks that drives into flooded basements, carparks and tunnels and pumps them out. Exactly a year later, on 12 November 2026, PUB began a one-year trial of the rover as one of the new pieces of flood management technology it rolled out that day — and the story ran across Singapore’s national news.
Dotek designed the rover; Hoppt manufactured it for them as their OEM manufacturer. Uni-Corp Singapore introduced it to PUB, led the discussions and ran the live demonstration. Getting it from the factory to a national flood trial took both: Hoppt’s manufacturing and Uni-Corp Singapore’s business development.
With thanks to Dotek and Meizhuan Builders
We’re grateful to Dotek for trusting us to build their design, to Meizhuan Builders, the contractor working with PUB, and to everyone at Hoppt and Uni-Corp Singapore who built the rover and brought it to PUB.
Why a robotic pump
When a basement or tunnel floods, the conventional set-up is a lorry carrying pumps, a diesel generator and hoses. It can take an hour or more to set up, it is hard to get into tight spaces, and anyone wading in risks live electrics.
The rover goes in instead. One person fixes a hose to it, runs the other end to the nearest drain that isn’t flooded, and drives it in by remote control from up to 100 m away. PUB says it can also help with coastal flooding, when high tide and heavy rain arrive together and the tide gates have to stay shut. With flash floods in Singapore most likely in the November–January rainy season, PUB is starting the trial now.
What it can do
PUB’s figures, as reported by The Straits Times:
- Pumps 500 m³ an hour, twice PUB’s largest portable pump in the conventional set-up.
- Amphibious: works in flood water up to 70 cm deep.
- Runs on tracks, not wheels, so it crosses uneven ground and climbs stairs.
- Runs for at least seven hours; weighs 800 kg.
And from the 2025 demonstration:
- Runs 7–8 hours on a 70-litre fuel tank, pumping down to 10 cm of standing water.
- Stones up to 25 mm pass straight through the pump.
- Several units can be connected in series to push water up a 40 m head.
- The hose roller winds the hose back in and squeezes the water out as it goes, then folds small enough to carry on a truck.
Watch the 2025 demonstration
The film is from that day at Pandan Garden. PUB officers and contractors, Meizhuan Builders among them, watched the rover drive through a 12 m³ test pool, pump water 100 m away, take stones through the pump, and lay out and wind up its hose.
