If m²: Surface (cm²) = Surface (m²) × 10,000
2

Select Cleaning Efficiency Factor

Light = 4 | Moderate = 6 | Heavy = 8
3

Calculate Brush Head Area

Area = Surface Area ÷ Efficiency Factor
4

Calculate Handle Length

Handle (cm) = User Height (cm) × 0.6

Detailed Real-Life Example

Ex

Cleaning Outdoor Tiles

Given Data
  • Surface Area 4800 cm²
  • Cleaning Type Heavy (Factor 8)
  • User Height 170 cm
Calculation Results
Brush Area (4800 ÷ 8) 600 cm²
Handle Length (170 × 0.6) 102 cm
Final Recommendation:
  • Brush Head ≈ 20 × 8 cm
  • Handle Length ≈ 100 cm
  • Bristles: Hard or Stiff
  • Suitable Category: Large or Industrial Brush

Formula Summary

Brush Area (cm²) = Surface Area ÷ Cleaning Efficiency Factor

Handle Length (cm) = User Height × 0.6

Tips for Choosing the Right Scrub Brush

Bristle Selection

  • • Pressure: Avoid excessive pressure; let the bristles perform the scrubbing work.
  • • Multi-purpose: Detachable handles allow for versatile cleaning options.

Maintenance Tips

  • Rinse: Rinse thoroughly after each use to remove chemicals and debris.
  • Dry: Hang vertically to dry, ensuring bristles aren't bent.
  • Disinfect: Disinfect weekly using vinegar or a mild detergent solution.
  • Replace: Replace simple brushes every 3–6 months for hygiene.

Frequently Asked Questions

What size scrub brush is best for bathroom tiles?
For bathroom tiles, a medium brush around 15 × 7 cm with medium bristles is typically ideal to handle grout lines without being too unwieldy.
How do I calculate brush size for large floor areas?
For large floors, use the calculator to find the total area. Generally, you'll need a Large or Industrial brush (20 × 8 cm or larger) with a long handle to cover ground efficiently.
What bristle type should I use for outdoor cleaning?
Outdoor surfaces like concrete or stone require Stiff or Hard bristles to remove stubborn dirt and withstand the rough texture.
How long should a scrub brush handle be?
Ideally, the handle should be about 60% of your height to allow you to clean floors without excessive bending. For most adults, this is between 100 cm and 120 cm.
Can I use one brush for all cleaning tasks?
It's not recommended. You should separate brushes by area (e.g., bathroom vs. kitchen) for hygiene, and by bristle stiffness (soft for delicate, hard for durable surfaces) to avoid damage.
