Should I Repair or Replace My Vacuum?
Repair if the quoted repair price is under 50% of a comparable new vacuum's price and the unit is under 7 years old. Replace if both fail. That is the bench rule of thumb. The brand changes the math.
The 50% rule, with brand context
| Brand tier | Service-life expectation | Repair threshold |
|---|---|---|
| Miele, Sebo, Riccar, Kirby, Rainbow | 15 to 20 years | Repair at 60% or below, through year 14 |
| Dyson V-series | 6 to 10 years | Repair at 40% or below, through year 6 |
| Hoover, Bissell, Eureka | 5 to 8 years | Repair at 50% or below, through year 4 |
| Shark | 4 to 7 years | Repair at 50% or below, through year 3 |
The math worked example
A 6-year-old Miele Complete C3 Marin comes in with a $180 repair (motor brush rebuild and HEPA filter). Comparable new Marin at retail is $1,100. Repair is 16% of new. The unit has another 6 to 8 years of service life. Repair, no question.
A 4-year-old Shark Navigator comes in with a $90 repair (motor and switch). Comparable new Navigator is $200. Repair is 45% of new. Borderline by the 50% rule. The unit has maybe 3 more years of life. Depending on customer preference, either choice is defensible.
A 7-year-old Hoover comes in with a $120 repair (motor). Comparable new Hoover is $130. Repair is 92% of new. Replace.
What we factor in beyond the math
- Sentimental value. A 25-year-old Kirby that belonged to a grandparent gets a different math. Often worth fixing for its own sake.
- Environmental cost. Repair is almost always lower-carbon than replacement.
- Upgrade temptation. If you've been thinking about upgrading to Miele anyway, a repair on the old vacuum is a delay tactic.
- Specific model risk. Some models have known failure cascades. We will tell you if the next failure is likely to be expensive.
How to use this guide
- Bring the vacuum in for a free diagnosis.
- We tell you what's wrong and quote the repair.
- You compare to a new vacuum in the same tier (or one tier up).
- Apply the 50% rule and the 7-year cutoff. Decide.
- If you decide not to repair, no charge for the diagnosis.
Common questions
- What is the 50% rule for vacuum repair?
- If the quoted repair price is under 50% of a comparable new vacuum's price AND the unit is under 7 years old, repair. If both fail, replace. The rule is approximate; brand changes the math.
- Are some brands always worth repairing?
- Yes. Miele, Sebo, Kirby, Riccar, and Rainbow have 15 to 20-year service lives and rebuildable platforms. Repairs at year 14 are usually still worth it.
- Are some brands rarely worth repairing past a certain age?
- Yes. Mass-market Shark, Hoover, Bissell, and Eureka have 5 to 8-year service lives. Past year 5 with a major repair (motor, PCB), replacement is usually better.
- Does the brand of the new vacuum I'd replace it with matter?
- Yes, significantly. If you would replace with another mass-market unit, the 50% rule holds. If you would upgrade to Miele, almost any repair on a mass-market vacuum loses to upgrade.
- What about environmental cost?
- Repair is almost always lower-carbon than replacement. The motor and chassis on a 5-year-old vacuum represent thousands of dollars of materials and embodied energy. A $90 belt and brush rebuild keeps it out of landfill.
