Floor Cleaning (Shared Areas, Sales Floors, After Hours)

Staff spent about 3 hours a day mopping floors.

An 18-day trial on two floors of a nursing home.

Estimated 90 staff-hours a month freed and cleaning costs cut 67% (¥103,000/month).

Hiring difficulties, an aging cleaning staff and rising minimum wages were eroding the economics of store cleaning.

Contractors sign for and run the robots: Whiz i on ceramic floors, wet-mopping Phantas on plastic-tile floors, now across 120 stores.

Cleanliness maintained at lower cost, contractor margins improved, and families with children respond well.

45% of cleaners were agency staff with frequent absences, and manual tank emptying took 7 minutes a cycle, so quality and efficiency were inconsistent.

From October 2022, 34 robots and 18 charging docks were deployed across check-in areas and airside.

1,760 staff-hours freed a year, up to 80% of water recycled; reported net savings of £124,175 over five years with a 64% ROI.

Reduce floor-cleaning work for store staff and standardize quality across a 4,000+ store network.

After a test phase, 200+ units were rolled out to German stores; distributor Philon provides an all-inclusive service package.

Cleans a whole store unsupervised in about 1.5 hours; standard in new stores, with a second phase planned.

Expanded fresh-produce ranges increased daily floor cleaning, while food retail demands high hygiene.

After a four-store pilot, rollout began in fall 2025; distributor Robobee handles training and maintenance.

200 units in service; more than double the cleaning productivity, up to 2,000 m² on about 15 L of water.
