The Science of Cleanability

Cleanability is designed in, not cleaned in.

Cleanalytix quantifies how built-environment design determines cleaning effort, hygiene consistency, and sustainability outcomes — through a structured Cleanability Index.

Chapter 4 — Defining Cleanability

Cleanable vs Non-Cleanable Washroom

Low Cleanability

  • Floor-mounted fixtures
  • Tight corners & joints
  • Grouted surfaces
  • Hard-to-reach areas
  • Higher labour effort
  • Inconsistent hygiene outcome

High Cleanability

  • Wall-mounted fixtures
  • Open access geometry
  • Seamless surfaces
  • Easy reach cleaning
  • Lower labour effort
  • Consistent hygiene outcome

Chapter 6 — Productivity

CI defines potential. PI measures speed. COI validates outcome.

  • Training
  • Supervision
  • Equipment
  • Chemicals
COI

Cleaning Outcome

  • Audit scores
  • Hygiene levels
  • Consistency

Structured Measurement of Cleanability

The CI provides a repeatable score that ties design choices to operational reality.

Geometry

Open layout, wall-mounted fixtures, no tight corners

28/40

Surface

Seamless, non-porous, low grouting

22/35

Access

Reach, sightlines, equipment maneuverability

16/25

Cleanability Index

66

/ 100

Good

Solid cleanability with room for targeted improvements.
