Height Risk
Rope access and scaffolding place workers in hazardous high-rise environments.
More than a final year project. A complete building maintenance concept.
From design and fabrication to waterproofing, flight testing, and software integration, SkyScrub was developed as a practical engineering platform.

The Problem
Traditional façade cleaning is risky, slow, and labour-intensive.
Setup Time
Conventional methods require manpower, staging, permits, and long preparation windows.
Limited Data
Cleaning and inspection are often separated, making defect tracking slower.
The Solution
One drone platform. Cleaning, inspection, and reporting in a single workflow.
Ground-fed Cleaning
Water is supplied from the ground to reduce onboard drone mass.
Waterproof Protection
Protected electronics support operations around cleaning mist.
AI Inspection
CrackScan records crack evidence for future reporting.
Prototype
SkyScrub Mark I.
The first integrated prototype developed to validate high-pressure façade cleaning, waterproofing, structural integrity, and AI-assisted inspection.
Next Generation
SkyScrub Mark II.
The refined prototype integrates modular waterproofing, improved system packaging, LiDAR sensing, AI-assisted inspection and a ground-fed high-pressure cleaning system.
Software
CrackScan.
AI-powered crack detection software that stores inspection records with screenshots, timestamps, and location fields.
