After hours, the robots clock in: CHASING’s event-grade pool cleaner keeps World Games pools on pace

CHENGDU, China — At 10 p.m., after the final medal photos, the natatorium goes quiet. Lights dim to a cool blue, lane lines settle—and CHASING’s pool-cleaning robots slip under the surface. Through the night, they trace disciplined paths along tile and waterline so the morning’s heats can start on time.

Built for multiple scenarios: from event standards to household needs

As the 12th World Games wrapped in Chengdu, CHASING’s pool cleaner drew notice for handling elite demands while fitting everyday life. According to the company, two units deployed at the Chengdu Sport University and Jianyang Donglai Impression Sports Center ran 16 consecutive days with zero failures, a result the team credits to an event-grade design built for reliability, strong suction and high cleanliness.

International event assurance (sports venues/resorts)

The World Games sets a high bar for aquatics operations: 24/7 adherence to World Aquatics (formerly FINA) competition standards (turbidity at or below 0.5 NTU; pH 7.2–7.8), 90-minute cleaning windows between training and competition, and no downtime during events. In Chengdu, the company highlights three advantages:

• Reliability. Logs from the two venues show two robots ran 16 straight days without failure, serving more than 2,000 athlete uses per day without a minute lost to equipment issues, according to the company.
• Cleaning performance. Dual 1,500 pascal (Pa) water pumps pull up grit and hair from the floor, while a high-density nylon brush scrubs walls and the waterline. Within a 90-minute window—the typical turnover—the company reports about a 67 percent efficiency gain versus manual crews, with residual impurities below 1 percent.
• Intelligent dispatch. For large venues, the platform supports multi-robot collaboration, automatically allocating zones over 500 to 2,000 square meters of pool surface. An event emergency mode lets a technician trigger a precise spot clean in about 10 seconds to handle dropped caps, goggles or other debris.

Home-pool optimization (villas/yards/private pools)

For private pools sized 20 to 500 square meters, CHASING “lightens” the same technology so pro-level cleaning slots into daily routines. A simplified app offers one-tap, fully automatic cleaning with scheduled runs (for example, Saturdays at 8 a.m.), plus manual remote passes for corners and steps. The unit is compact and agile at about 8 kilograms, with a storage footprint under 0.2 square meters. Noise is rated to about 55 decibels (dB) — about the same level as a normal conversation — and power draw is about 150 watts. By the company’s estimate, households can save more than $3,000 a year (based on a $70 weekly cleaning service) by shifting to scheduled robotic cleaning.

What users say

Venue operations staff in Chengdu described moving from a six-person rotation to two robots over the 16-day meet, with water quality meeting competition standards and labor being redirected to lifeguard coverage. In Phuket, a five-star resort manager reported a 45 percent drop in pool operations costs and guest feedback that water looked clearer after deployment.
Homeowners echoed the gains: a California family said weekly $150 cleaning bills—$7,800 a year—were eliminated by scheduled runs visible in the app; a Melbourne household pointed to cleaner step areas and quiet nighttime operation that didn’t bother neighbors.

From professional to everyday: event-grade quality at global scale

The World Games deployment served as a stress test and a springboard. According to the company, CHASING now serves sports venues in 32 countries and plans in 2025 to expand to 15 additional large multi-sport complexes across Europe and the Middle East. 

In high-end hospitality, the cleaner has rolled out to 12 flagship resorts—including Australia’s Gold Coast and the Maldives—where guest satisfaction with water quality rose about 28 percent. 

For households, the home series ships to 56 countries, supports 100 to 240 volts (V) worldwide and automatically adjusts cleaning modes for soft or hard water with no retrofits.

Standards

The product line is ISO 9001 certified and CE/RoHS compliant. Unless noted otherwise, figures above are according to CHASING and on-site venue staff.

“Our aim isn’t to build only for professionals,” said the chief product officer at CHASING. “We want the competition-grade cleaning you see at world events to be a simple, safe and efficient everyday experience at home.”
