Decision Framework: Step-by-Step Guide for Different Buyer Profiles

There's no single "best" power configuration – only the best fit for your specific situation. Use this framework to evaluate your needs systematically.

Step 1: Define Your Primary Application

Application Type	Typical Power Range	Priority Factors
Auto detailing shop	1-3 kW	Portability, ease of use, pad compatibility
Commercial floor cleaning	5-15 kW	Runtime, tank capacity, maneuverability
Furniture finishing	3-10 kW	Speed control precision, dust extraction
Metal fabrication	5-20 kW	Durability, continuous operation capability
High-volume contract polishing	20-50 kW	Throughput, automation integration, consistency

Step 2: Calculate Your True Production Requirements

Don't guess – calculate:

Daily/weekly volume: Square meters or number of parts to process
Cycle time per unit: How long does each piece take?
Operating hours: Single shift (8hr), double shift (16hr), or continuous (24hr)?
Growth projection: Will you need 20% more capacity in 2 years? 50% in 5 years?

Example calculation:

Need to polish 500 square meters daily
Machine processes 50 sqm/hour at optimal speed
Required operating time: 500 ÷ 50 = 10 hours
With 8-hour shift: Need machine with 500 ÷ 8 = 62.5 sqm/hour capacity
This likely requires 10-15kW equipment, not 3kW

Step 3: Assess Your Facility Constraints

Be realistic about limitations:

Electrical capacity: What voltage and amperage are available? Upgrading costs?
Floor space: How much room for equipment + material handling?
Ventilation requirements: Does your facility support dust extraction needs?
Operator skill level: Can your team operate complex automated systems?

Step 4: Evaluate Total Cost of Ownership

Create a 5-year TCO model:

Purchase Price: $X,XXX Electrical Upgrade (if needed): $X,XXX Annual Energy Cost: $XXX × 5 years = $X,XXX Annual Consumables: $XXX × 5 years = $X,XXX Maintenance (estimated 5% of purchase price/year): $XXX × 5 = $X,XXX Training & Setup: $XXX

5-Year Total Cost of Ownership: $XX,XXX Cost per unit (based on projected volume): $X.XX

Compare this across 2-3 equipment options before deciding.

Step 5: Consider Your Growth Trajectory

If you're a startup or small operation:

Start with 1-5kW equipment to minimize initial investment
Choose modular systems that can be expanded later
