What UK Retail Can Learn from Tesco's 600-Store Autonomous Floor-Cleaning Rollout

Tesco's rollout of autonomous cleaning robots across 600 Express stores is a clear sign that robotic floor cleaning is moving from isolated trials into everyday retail operations.

The programme was reported in June 2026 and reached its 600-store milestone by the end of July. Tesco worked with industrial cleaning equipment specialist ICE, with the robots intended to work alongside store colleagues rather than replace them. Their role is to handle routine floor cleaning, provide cleaning data and help teams maintain consistent standards across multiple locations.

What happened in Tesco's 600-store rollout?

According to Retail Gazette, Tesco introduced autonomous cleaning robots across 600 Express stores in partnership with ICE.

A later report confirmed that the initial phase had been completed and described the deployment as one of the largest of its kind in the UK convenience sector. The programme involved:

• Routine autonomous floor cleaning across 600 stores.
• Robots working alongside Tesco colleagues.
• Cleaning data and performance reporting.
• Training, maintenance and ongoing support.
• Feedback from store employees using the technology.

The important point is not simply the number of robots involved. It is the operational model behind the rollout: the robot is treated as part of the cleaning process, not as a standalone technology experiment.

For retailers considering automation, that is the first practical lesson.

Lesson one: Start with a repeatable operational problem

Autonomous floor cleaning is most useful when it addresses a task that is:

1. Repetitive.
2. Carried out frequently.
3. Time-consuming for staff.
4. Important to customer experience.
5. Suitable for a predictable route.

Retail floor cleaning fits these criteria particularly well. The same aisles, concourses, entrance areas and open floor spaces need to be cleaned repeatedly, often within a limited overnight or early-morning window.

Manual cleaning remains essential for spills, edges, corners, fixtures, toilets and detailed work. However, routine floor coverage can take up a large part of a cleaning shift. A robot can handle that repeatable work while staff concentrate on tasks that require judgement and attention.

This is the practical meaning of a “co-bot”: technology that supports the team rather than replacing it.

Lesson two: Choose the robot according to the floor

Not every retail floor needs the same type of cleaning robot. The right choice depends on the surface, the cleaning method required and the size of the area.

Keenon KLEENBOT C30: dry cleaning for mixed retail environments

The Keenon KLEENBOT C30 is a three-in-one dry floor cleaner. It sweeps, vacuums and dust-mops in a single pass.

It is suited to:

• Hard floors such as tile, vinyl, stone and wood.
• Short-pile carpet, subject to the manufacturer's limits.
• Retail stores with mixed flooring.
• Department store areas where dry cleaning is preferred.
• Smaller or medium-sized commercial floor areas.
• Overnight cleaning where water use is unsuitable.

The C30 is not a replacement for a heavy-duty wet scrubber. It is a dry-cleaning model designed to remove dust, debris, crumbs and everyday floor contamination consistently.

Keenon KLEENBOT C40: wet and dry cleaning for larger hard floors

The Keenon KLEENBOT C40 is designed for larger commercial spaces and combines sweeping, scrubbing, vacuuming and drying.

It is more suitable for:

• Supermarket and large-store floors.
• Shopping centre concourses.
• Retail parks and food courts.
• Large hospitality and leisure venues.
• Hard floors that need regular scrubbing.
• Sites with a defined overnight cleaning window.

The C40 can clean at up to 1,100 square metres per hour, according to Fresh Mango Robotics' product information. It can scrub for up to approximately five hours or sweep for longer, depending on the selected cleaning mode and operating conditions.

The figures are useful for initial planning, but actual coverage depends on the floor layout, obstacles, cleaning settings, traffic and the amount of detail work required.

Lesson three: Customer traffic must shape the schedule

A retail robot should not simply be switched on and left to operate without a plan. Scheduling is one of the most important parts of a successful deployment.

Most retailers will schedule cleaning:

• After closing.
• Before opening.
• During quieter trading periods.
• In sections of the store that can be temporarily managed.
• Around deliveries, replenishment and maintenance activity.

Some robots can operate safely around people using sensors, LiDAR navigation and obstacle detection. Even so, customer traffic can slow the route and make cleaning less efficient. A busy store may also require the robot to pause more frequently.

A site survey should therefore consider:

• Opening and closing times.
• Busy and quiet periods.
• Delivery schedules.
• Stock replenishment routes.
• Checkout and queue areas.
• Promotional displays.
• Temporary obstacles.
• Emergency exits and restricted areas.
• Charging and storage locations.

The objective is not necessarily to clean while customers are present. Often, the most effective approach is to use the robot during a defined out-of-hours window and keep staff available for spot cleaning and exceptions.

Lesson four: Safety depends on deployment, not just sensors

Autonomous navigation is an important part of a cleaning robot, but safety also depends on how the site is prepared and how staff are trained.

Before installation, the retailer and supplier should agree:

• Where the robot can operate.
• Which areas are excluded.
• How spills and obstructions are handled.
• What happens if the route is blocked.
• How staff stop or redirect the robot.
• Where the robot docks and charges.
• How cleaning chemicals and consumables are stored.
• How the system is monitored during its operating window.

Retail staff should understand that the robot is a working piece of commercial equipment. They need simple instructions for starting a route, pausing the machine, clearing minor obstacles and reporting issues.

Good training also helps the team see the robot as part of their workflow rather than an unfamiliar machine competing for space on the shop floor.

Lesson five: Consistency matters as much as labour efficiency

The strongest reason to consider autonomous floor cleaning is not always a headline cost saving. For many retailers, the more valuable benefit is consistency.

A robot can be programmed to follow the same route and cleaning schedule repeatedly. This can help reduce variation between shifts and locations.

Useful operational outcomes include:

• Clean and dry floors before opening.
• Fewer routine cleaning tasks on the staff rota.
• More consistent coverage across departments.
• Better use of cleaning staff time.
• Recorded routes and cleaning activity.
• A clearer standard for multi-site operations.

For a retailer with multiple stores, consistency can be particularly valuable. A defined cleaning routine is easier to review, improve and replicate than an informal process that depends entirely on who is working that night.

Maintenance and support should be part of the plan

A cleaning robot is not maintenance-free. Brushes, filters, squeegees, batteries, tanks and other components need regular attention.

The supplier should explain:

• What staff need to clean after each shift.
• How often consumables are replaced.
• How faults are diagnosed.
• What response times apply.
• Whether spare parts are held in the UK.
• How software updates are delivered.
• Who provides on-site engineering support.
• What happens if a robot is temporarily unavailable.

Fresh Mango Robotics supplies and supports the Keenon C30 and C40 with site surveys, installation, mapping, staff training, software updates, maintenance and UK-based support.

That ongoing service is important because the value of a cleaning robot comes from regular operation. A machine that is difficult to maintain or left unused after a minor issue will not deliver the expected operational benefit.

Robotics as a Service can make adoption easier

Retailers do not necessarily need to purchase a cleaning robot outright.

Fresh Mango Robotics offers the Keenon C30 and C40 through:

• Outright purchase.
• Robotics as a Service (RaaS).
• Hybrid ownership and support arrangements.

With RaaS, the retailer avoids a large initial capital outlay and pays a predictable monthly operating cost. Maintenance and servicing are included, along with software updates and UK-based support.

This can make it easier to test autonomous cleaning at one store before considering a wider rollout. It also allows cleaning automation to be budgeted alongside other operational services rather than treated solely as a major equipment purchase.

RaaS is not automatically the cheapest option over the full life of a robot. Its value is in reducing upfront risk, simplifying support and making costs more predictable.

A practical checklist for retailers

Before choosing an autonomous cleaning robot, ask:

1. What floor types need cleaning?
2. Is dry cleaning or wet scrubbing required?
3. How many square metres need to be covered?
4. What is the available cleaning window?
5. How busy is the site during that period?
6. Are aisles and access routes wide enough?
7. Where can the robot charge and, if required, refill?
8. Who will manage daily checks?
9. How will spills, displays and temporary obstacles be handled?
10. What maintenance and support package is included?

A supplier should be able to answer these questions through a site survey and live demonstration, rather than relying only on a product brochure.

Conclusion

Tesco's 600-store rollout shows that autonomous floor cleaning is becoming a practical operational tool for UK retail.

The technology is not about removing people from the cleaning process. It is about assigning repetitive floor coverage to a reliable machine so retail teams can spend more time on customers, replenishment, detail work and the tasks that require human judgement.

For retailers considering the next step, the priorities are straightforward:

• Match the robot to the floor type.
• Plan around customer and delivery traffic.
• Complete a proper site survey.
• Train staff before deployment.
• Build maintenance and support into the commercial model.
• Start with a manageable pilot if required.
• Choose between purchase, hybrid support and RaaS based on your budget and operating model.
