Bottom line
The workhorse that built a thousand laser-hair-removal businesses — and on the 2026 used market, arguably the best dollars-per-treatment-hour deal in aesthetics: ~$12k-30k buys the same vacuum-assisted HS concept Lumenis still sells at flagship prices. It's 805nm only, so darker skin types need conservative settings and real operator skill. Units are 10-15+ years old: buy on handpiece pulse counts and service history, not cosmetics.
Overview
High-speed vacuum-assisted large spot
How it works
The science
Single-wavelength 805nm diode — melanin absorbs, heat destroys the follicle's regenerative structures. Sweet spot is Fitzpatrick I-IV; V-VI treatable with longer pulses, lower fluence, and an experienced hand. Cleared for hair removal/permanent reduction; also treats pseudofolliculitis barbae well — a meaningful niche in diverse markets.
Patented tech
Two handpieces define it: the HS 22x35mm vacuum-assist (gel-free, fast, lower-pain) and the ET 9x9mm with ChillTip sapphire cooling for precision and darker skin. The vacuum-assist concept was genuinely innovative in 2009 and still holds up.
Origin
Yokneam, Israel (Lumenis).
FDA & regulatory status

510(k) numbers
K053628
Regulatory data is compiled from public FDA 510(k) records and may lag recent clearances. Always confirm status with the manufacturer before purchase.
Treatment economics
What practices charge
Same menu as any diode: ~$75-150 small areas, ~$250-450 legs/back, 6-packs at 20-30% off. A $20k used Duet doing 15 sessions/week at a $120 average grosses ~$90k/year — that's why they still sell. Patients don't pay less because your laser is older.
Consumables & recurring cost
None per treatment. The real cost is aging diode stacks — a dead HS handpiece rebuild runs ~$6k-12k third-party, and vacuum pump repairs come up. Ask for pulse counts on both handpieces before wiring money.
Ideal for
Best-fit practice
Budget-conscious startups, laser bars, second-room additions in Fitzpatrick I-IV markets. If your base is heavily V-VI, buy an Nd:YAG or dual-wavelength machine instead and skip the liability.
Compliance
Medical director & delegation
Class II prescription device; same medical director and state-variable operator rules as any hair laser, regardless of age.
Contraindications & screening
Recent tan (higher stakes at 805nm-only), isotretinoin, pregnancy, photosensitizers, active infection, keloid history; honest counseling on gray/white/blonde hair.
Ownership
Warranty & service
Factory warranty long gone; you're in third-party service land — a strength, since Duet parts, techs, and refurbished handpieces are plentiful. Dealer refurbs include 90 days-1 year; contracts ~$5k-8k/year. Buy from a dealer who stocks handpieces.
Resale & used market
One of the most liquid used lasers in existence — constant trade at ~$10k-30k. Prices drift down slowly; liquidity means you can exit in weeks.
