Founded in 1933, Universidade Federal de São Paulo (UNIFESP) is ranked among the top-five public research universities in Brazil. Its five campuses sprawl across 7 km² of São Paulo State, enrolling 25,000 students and operating the country’s largest tertiary-care teaching hospital.

• Buildings range from 1950–1980 heritage blocks to new glass-walled laboratories, mixing terrazzo, PVC and polished tile floors
• The campus is open 24 h; laboratory corridors, outpatient passages and teaching wings share the same traffic spine, receiving 60,000 users a day
• In QS 2024 the university lists both “Green Campus” and “Zero Slip Accidents” in its five-year strategic plan

Pain Points

Multi-surface floors, one machine hard to fit all

• Medical-department corridors use scratch-prone old terrazzo; new research blocks have high-gloss porcelain
• Traditional mop + dust-mop sets required four tool changes and left streaks

Time and noise constraints

• OR floors may be wet-cleaned only 01:30–04:00; noise must stay ≤ 68 dB(A)
• Although the old variety carried 70 L, its chassis has no elevator wheels and the handle sits too low. Maneuvering it through the medical building’s narrow lifts and turning ramps is awkward; each cross-floor trip to dump and refill takes an average of 30 minutes and requires two operators, eating up the already short after-midnight cleaning window

Budget & staff “double squeeze”

• Public-university budget freeze cut cleaning staff from 186 to 142
• Needed one unit that could replace 3–4 workers and pay for itself within three years

Solution: GIYO X6 Walk-Behind Floor Scrubber

In November 2023 UNIFESP’s asset office invited five brands for a field test; 12 GIYO X6 units were chosen as the flagship machines for a “zero-slip demo” in the busiest medical tower, the central library and the coastal Santos Medical Sciences campus.

Core Highlights

One machine, multiple brushes – soft and hard brush sets supplied; 30-second tool-free change. Soft bristles for terrazzo (no scratches), hard bristles for porcelain stain removal

Large tanks + snap-change battery – 45 L solution / 50 L recovery, 3 h continuous run; 10-second drawer-style battery swap meets 24-hour shift work

Quiet brushless motor – 68 dB, quieter than library HVAC; approved for post-midnight OR floors

IoT slot – optional 4G module uploads water level, battery SOC and location to campus CMMS for data-driven scheduling

Corrosion-resistant body – rotomoulded PE shell passes 1,000 h salt-spray test, ideal for the salty coastal Santos campus

Week Milestone

Results & Benefits

Productivity boost

• One X6 replaces 3.3 staff; annual payroll savings BRL 384 k (≈ US $75 k)
• Medical-tower 4-hour window shortened from “5 staff + mops” to “2 staff + X6”

Safety & compliance

• Zero slip incidents in six months; 2024 insurance premium reduced 12 %
• Passed TÜV Süd on-site audit; awarded “Zero-Slip Demonstration Campus” certificate

Green campus

• Chemical consumption ↓ 30 %, water use ↓ 28 %, 1,100 t less wastewater per year
• Over its 3-year life cycle the fleet will save the university approx. BRL 1.2 million in OPEX

Reputation

• QS Sustainability 2024 indicator “Campus Facilities” score improved 8 %
• UNIFESP included GIYO X6 in its public “Carbon Neutral Roadmap 2030” report

User Voice

“The same machine switches between terrazzo and tile without leaving marks. We push it through surgical wards at 2 a.m. and receive no complaints. The dashboard even shows real-time water use—perfect transparency for researchers.”

— Carlos Eduardo Silva, Campus Asset & Maintenance Manager
