Underground Garages
- Zero Emissions: 100% electric and safe for enclosed subterranean parkades and ramps.
- Salt & Dust: Sweeps tracked-in winter salt, tire rubber, and fine grit before it enters lobbies.
Clear snow, slash salt, work year-round.
Frost-E is an autonomous electric rotary power sweeper engineered for continuous 24/7 campus operations. Strip pedestrian paths down to bare pavement in winter, slash salt consumption by 50%+, and maintain synthetic turf, autumn leaves, and spring hardscapes in the off-season.
- Bare pavement finish
- 50–75% Salt reduction
- Real-time ice detection
- 4-Season grounds care
Frost-E Clears Continuously to Bare Pavement.
Traditional snow clearing encourages ice formation, while superior rotary sweepers are too cost-prohibitive to employ continuously. Frost-E sweeps autonomously in continuous cycles throughout snowfall, bringing a superior clean at a lower cost.
Traditional Post-Storm Plowing
❌ The Scraping Dilemma
Delayed Deployment: Plows only run after accumulation builds up, allowing foot
traffic during the storm to pack snow into bonded ice sheets.
Compacted Glaze Sheets: Rigid steel blades skate over compacted footprints and
uneven pavers, leaving a 2–5mm slick sheet behind to freeze.
Heavy Chemical Dependency: Crews must dump tons of rock salt to burn through the
hard-packed crust, leading to high chemical costs.
Manual Sweeping Limitations: Rotary brooms provide the best finish but only work
on low snow depths, making 24/7 human sweeping impossible.
Frost-E Autonomous Power Sweeper
✅ Continuous Bare Pavement Sweeping
Clears During Snowfall: Deploys autonomously throughout the storm, continuously
clearing small amounts before foot traffic can compact it.
100% Bare Pavement Finish: High-speed polypropylene bristles flick snow out of
pavement micro-pores, allowing sun and air to dry the surface.
Cuts Salt by 50% (~1 Ton/km): Eliminating the ice bond cuts chemical use in half,
saving ~1 ton of salt per km of sidewalk each winter.
Zero Overtime Fatigue: Runs 24/7 resident clearing cycles automatically without
emergency 3:00 AM crew call-out premiums.
Detects ice like a human
A mechanical tactile ice detector mounted at the back physically feels surface resistance and friction same way a person does.
Real-Time Ice Detection
Immediately detects loss of surface traction behind the broom and sends an alert for surgical spot-treatment.
Autonomous Ice Patrols
The robot can patrol walkways for hazardous freeze conditions even when it isn't snowing.
Impeccable Documentation
Every patrol logs time-stamped surface friction telemetry and GPS paths, creating indisputable digital proof of maintenance to defend against slip-and-fall claims.
Excels at snow, works year-round
Single-purpose snow machines sit idle most of the year. Frost-E works every season to solve high-frequency, labor-intensive institutional grounds tasks.
Synthetic Turf & Track
- Infill Decompaction: Gently cross-brushes crumb rubber to maintain GMAX concussion safety.
- Track Care: Clears stones and grit off rubberized running tracks without surface damage.
Autumn Leaf Clearing
- Whisper-Quiet: Runs silently, replacing loud gas blowers near dorms and lecture halls.
- Wet Foliage: Lifts wet, decaying leaves and needles before they create slip hazards.
Spring Sand & Gravel
- Pavement Care: Gathers winter traction gravel before foot traffic grinds it into coatings.
- Drainage Protection: Clears perimeter curbs and gutters to prevent clogged storm drains.

Accessibility
80 cm Width
Fits All ADA Pathways
Compact 1.3m × 80cm footprint easily navigates courtyards, narrow breezeways, and ramps where tractors cannot go.
Smart, Safety-First Self-Driving Technology
Operating safely in busy pedestrian corridors requires absolute precision and multiple redundant systems. Frost-E utilizes a 360° LiDAR and the same type of self-driving AI used in commercial robotaxis like Waymo.
360° LiDAR Safety Bubble
High-resolution 360° LiDAR creates a strict 3-meter exclusion zone day and night, instantly halting if a person or obstacle approaches.
Adaptive AI Navigation
Unlike rigid robots repeating pre-set loops, onboard AI dynamically maneuvers around novel obstacles like parked bikes, delivery carts, and cones.
Calm Walking Speed
Moves at a controlled walking pace (~3.6 to 5.0 km/h), eliminating collision risk and ensuring seamless operation alongside pedestrians.
