Buyer's Guide: Your 7-Year Cost Projection

Durability Checklist

Verify these features during purchase:

• Motor Warranty: ≥5 years (indicates brushless design)
• Seal Rating: IP68 or better
• Material Codes:
• 316 stainless (not 304)
• UV-stabilized polymers (look for "HDPE" or "PP-Copolymer")
• Service Network: ≤50-mile radius for authorized techs

Cost Calculation Formula

7-Year Cost = (Initial Price ÷ 7)

+ (Annual Maint. × 7)

+ (Initial Price × Replacement Probability*)

+ $120 (avg. energy)

+ $35 (disposal)

*Replacement Probability:

• Budget: 89% at Year 5
• Premium: 12% at Year 7

Residual Value Advantage

Premium models retain value for trade-ins:

• Year 5: 35% of MSRP (vs. 3% for budget)
• Year 7: 22% of MSRP (vs. 0% for budget)
