Le défi

AB Vassilopoulos is one of Greece’s most recognized supermarket brands and a subsidiary of Ahold Delhaize, one of the world’s largest food retail groups. With an extensive network of over 600 stores across the country and a strong e-commerce presence through AB Eshop, the chain serves millions of Greek households every week.

Maintaining consistently high standards of hygiene and cleanliness across such a large store network is a demanding operational challenge. Supermarket floors endure continuous foot traffic, shopping cart wear, and frequent spills throughout the day. Manual cleaning availability was inherently limited to specific shifts and hours, making it difficult to guarantee uniform results across all locations and times of day. Beyond pure efficiency, AB Vassilopoulos also wanted to strengthen its brand image through visible modernization of in-store operations — reinforcing its position as an innovation leader in Greek retail. The company sought a technology-driven solution that could deliver consistent daily cleaning quality and operational efficiency, while freeing staff to focus on higher-value tasks such as customer service and store operations.

La solution

AB Vassilopoulos selected Gausium based on Gerobo’s expertise and after-sales support, Gausium’s AI-powered cleaning technology, the autonomous Workstation capabilities, a modern and cost-effective approach to cleaning, and a shared commitment to continuous improvement.

Gausium Omnie is Gausium’s advanced autonomous floor scrubber, purpose-built for complex, high-traffic environments. Powered by 3D LiDAR with full 360° coverage and a panoramic camera system, Omnie delivers centimeter-accurate navigation and real-time obstacle avoidance — enabling it to operate safely alongside shoppers, staff, and shopping carts in busy retail aisles. The robot integrates scrubbing, sweeping, and dust mopping in a single unit, offering a generous 780 mm cleaning width supported by dual roller brushes and dual side brushes for thorough edge-to-edge coverage. Its AI-powered Spot Cleaning mode intelligently identifies and targets both dry and wet waste on the floor, ensuring precision cleaning rather than simply following rigid pre-programmed routes. With a 33L clean water tank for extended autonomous operation and full remote monitoring and scheduling via the Gausium cloud platform, Omnie is the ideal solution for retail environments that demand consistent cleanliness at scale.

Gausium Phantas is Gausium’s compact, all-in-one commercial cleaning robot, engineered for narrow aisles, tight corners, and the everyday layout constraints of supermarket environments. It combines sweeping, scrubbing, vacuuming, and drying in a single pass, giving each store consistent cleaning results with minimal supervision. Paired with the Gausium Workstation, each Phantas unit can autonomously dock, refill clean water, drain wastewater, and recharge — enabling true around-the-clock operation without manual intervention. Together with Omnie, Phantas covers the full spectrum of cleaning needs across the AB Vassilopoulos store network, from main shopping floors to back-of-house and high-density aisle areas.

Gerobo International managed the deployment under a cobotics philosophy, where autonomous robots and human teams work together in complete harmony. The implementation introduced collaborative AI cleaning robots into AB Vassilopoulos stores nationwide, enabling the chain to maintain spotless floors around the clock while preserving a safe, comfortable shopping environment for customers.

Les résultats

The deployment of Gausium Omnie and Phantas robots, supported by their autonomous Workstations, across AB Vassilopoulos stores has delivered meaningful improvements across multiple dimensions:

• 20% Reduction in Manual Floor Cleaning Time: By automating routine floor cleaning, AB Vassilopoulos reduced the time staff spend on manual floor cleaning by 20%. That reclaimed time is now redirected to the rooms and areas of each store that need the most attention, raising overall cleaning quality without adding headcount.
• Consistent Cleaning Quality: Autonomous operation ensures uniform floor cleanliness regardless of shift changes, peak hours, or store location. The robots deliver the same high standard every cycle, eliminating the variability inherent in manual processes.
• Reduced Resource Consumption: The robots’ efficient cleaning systems and intelligent path planning help lower energy and water usage compared to traditional methods, supporting AB Vassilopoulos’s sustainability goals.
• Data-Driven Operations: The Gausium cloud platform provides real-time cleaning statistics, remote operation control, and performance analytics, giving store managers full visibility into cleaning performance across all locations.
• Optimized Workforce Allocation: With robots handling routine floor maintenance, store personnel are freed up to dedicate more time to customer-facing activities and core retail operations. The visible result is a noticeably cleaner-looking floor, with both employees and customers reporting an improved perception of in-store cleanliness.

“We reduced the time spent on manual floor cleaning by 20%. The cleaning staff now spend more time looking after the rooms and areas that require the most attention, improving cleaning quality. The way in which employees and consumers perceive the cleanliness of the store has improved (the floor looks cleaner).”
