If you've decided you want a HANTENCNC pulsed laser cleaning machine, two come up most often: the SEAGULL2 (200W or 300W) and the SEAGULL3 (500W). The price difference is significant — $8,888–$9,999 for the SEAGULL2 vs $21,999 for the SEAGULL3 — but raw power isn't the right question to start with. The right question is: what does your work look like, day to day? This article maps real workshop scenarios to the right machine, with full specs, the five features that genuinely separate them, and the honest cases where you should stay on the cheaper machine.
TL;DR — which one for what
| If your work is… | The right pick is… |
|---|---|
| Occasional cleaning, restoration shop, single bay, delicate detail work | SEAGULL2 200W ($8,888) |
| Most-days cleaning, small custom fabrication, mixed jobs | SEAGULL2 300W ($9,999) |
| Production-line cleaning, most of every shift, one operator | SEAGULL3 500W ($21,999) |
| Travel between customer sites — on-call restoration, mobile service | SEAGULL2 (either power) |
| Heavy coatings, large surfaces, sustained throughput pressure | SEAGULL3 |
| Pipeline yards, refinery prep, tank shells, industrial scale | Neither — step up to DOLPHIN 1000–2000W |
| Pure paint stripping, low budget, throughput over precision | Neither — the CW SEAGULL4 is the budget play |
The 30-second gut check: If you'll spend 6+ hours of every shift cleaning, the SEAGULL3 pays back in shorter cycles and workflow ergonomics. If your cleaning time is sporadic, the SEAGULL2 saves you $13,000+ for capacity you wouldn't use.

Five features the SEAGULL3 has that the SEAGULL2 doesn't
1. A touchscreen on the cleaning head itself
This is the single biggest workflow difference between the two machines. The SEAGULL2 has its touchscreen on the trolley body — if you're standing at the workpiece with the cleaning head in hand and realize you set the wrong scan pattern, you walk back to the trolley to fix it. The SEAGULL3 has a second touchscreen on the cleaning head itself, with the active scan pattern, real-time head temperature, and the distance-sensor reading visible in your hand. Change the pattern, see the temperature, watch the working distance, all without setting the gun down. For solo operators in larger workshops or anywhere the trolley isn't next to the bench, this is the feature you'll feel every single day.
2. Twelve scan patterns vs eight
The SEAGULL2 supports eight patterns (line, mesh, circle, raster lines, concentric circles, grid, flower, infinity ∞). The SEAGULL3 supports twelve (Line, Rec1, Sine, Spiral, Cycle ring, Revolve, Rec2, Cycle, Triangle, Rotating circle, Rotation Line, Linear Rotation Circle). The extra four are mostly rotation-class patterns useful for complex part geometries and edge blending. For 80–90% of jobs, both machines have what you need — the line/raster patterns cover most production cleaning. The 12 patterns matter when your work mix includes a lot of triangular gussets, rotating part features, or specific edge-blending requirements that the SEAGULL2's patterns don't address natively.
3. Distance sensors that prevent operator mistakes
The SEAGULL3's cleaning head has min/max safe-distance sensors. The laser only fires when the head is at the correct working distance from the part — too close, no fire; too far, no fire. This catches operator mistakes that would otherwise damage the protective lens or produce poor cleaning results. The SEAGULL2 relies entirely on operator skill for distance management. For a single experienced operator, that's fine; for a shop with multiple operators or where you'll train new staff on the machine, the SEAGULL3's sensors reduce the chance of expensive mistakes.
4. Temperature monitoring and scheduled shutdown
The SEAGULL3's System Settings expose features the SEAGULL2 doesn't have at the same level: live temperature monitoring with a 50 °C threshold, scheduled laser shutdown (set the laser to disable after X minutes for unattended runs or shift-end safety), idle auto-shutdown for the whole machine, and a resettable operating-hours counter for service tracking. Together these turn the machine from "a tool an operator uses" into "a tool that looks after itself between sessions." For production environments, that's significant. For a one-person restoration shop, it's nice-to-have rather than essential.
5. Process recipe storage (Process selection)
The SEAGULL3's top-level menu includes "Process selection" — pre-saved process recipes that combine power, scan pattern, frequency, and speed into a single tap. If you do the same five or six job types repeatedly (clean rust off gears, strip paint from wood cabinets, remove heat tint from stainless welds, etc.), you save each as a process and your operator just picks one. The SEAGULL2 doesn't have this layer of stored recipes — the operator dials the parameters every time. For repeat production work, the time saving compounds; for a shop where every job is different, less so.
What the SEAGULL2 has going for it (besides price)
Half the price isn't the only reason people pick the SEAGULL2. Real advantages over the SEAGULL3:
- Half the weight. 27 kg vs 50 kg. Both are technically one-person moves, but at 27 kg you can carry the SEAGULL2 up steps without thinking; at 50 kg you plan the route. If your work involves loading a vehicle for on-site service, the SEAGULL2 is genuinely easier.
- Simpler UI. One touchscreen, fewer menu levels, less to learn. For shops where the machine will be used by multiple operators at different skill levels, the SEAGULL2's interface is faster to train on.
- The 200W option for delicate work. 500W is overkill on thin sheet metal, classic-car panels, fine restoration work, and detail cleaning. The 200W SEAGULL2 forces you to operate in the gentle end of the parameter range, which on delicate substrates produces better, more consistent results than dialing a 500W machine down.
- Pure portability. Trolley-and-go without a second thought. For mobile service businesses or shops that move the machine between bays multiple times per day, this is the reason to stay on the SEAGULL2.
- Eight scan patterns covers most jobs. If you don't have rotating part geometries or triangular features in your work mix, the four extra patterns on the SEAGULL3 are paying for capability you won't use.
What both machines clean
One thing the choice isn't about: what gets cleaned. Both machines handle the same application categories — rust on steel, oil stains, wood paint, oxide layers and weld heat tint, paint and coatings, and stone-brick paint removal. The difference is throughput, not capability. If a SEAGULL2 can clean your parts at all, a SEAGULL3 can clean them faster; if a SEAGULL3 can't clean a substrate (highly reflective polished aluminum, copper without parameter tuning, etc.), a SEAGULL2 won't either. For a wider look at what laser cleaning does (and doesn't) do, see what materials can be laser cleaned and what contaminants can laser cleaning remove.
The decision framework: walk it backwards from your shop
Skip the spec sheet and answer these four questions:
- How many hours per shift will the machine actually run? Under 3 hours: SEAGULL2. 3–6 hours: SEAGULL2 300W is usually enough. Over 6 hours steadily: SEAGULL3 starts paying back through workflow efficiency.
- Who will operate it — one trained person, or several people across shifts? One trained person: either machine. Multiple operators / training new staff: SEAGULL3's distance sensors and lockout features earn their keep.
- Will the machine move — between bays, between sites, in and out of a van? Frequent moves: SEAGULL2. Stays in one bay: either.
- Is your typical contamination delicate or heavy? Delicate (thin coatings, fine restoration, classic-car panels): SEAGULL2 200W. Mixed: SEAGULL2 300W. Heavy industrial coatings: SEAGULL3 minimum.
Score 0–1 SEAGULL3-leaning answers: SEAGULL2 200W or 300W. Score 2–3: it's a real coin-flip, talk to us. Score 4: SEAGULL3.
When neither is the right answer
- Industrial scale — pipeline yards, refineries, large tank shells, shipyards. Step up to the DOLPHIN 1000–2000W industrial for sustained heavy-duty cleaning. Our pipelines, tanks, and oil & gas guide covers the use cases.
- Tank exteriors and tall ferrous structures. Add the magnetic wall-climbing robot for vertical-only work, paired with a handheld unit for everything else.
- Pure budget paint stripping where pulse precision isn't critical. The SEAGULL4 is a continuous-wave alternative starting at $4,699 — less precise on delicate substrates than pulsed, but cheaper and adequate for paint-stripping-focused work.

What to do next
If you've worked through the decision framework and landed on a clear pick, the product pages have the rest: SEAGULL2 200W/300W or 500W SEAGULL3. If you're between the two, that's the most common decision-stage place to be. Tell us your typical job mix, hours per shift, and whether the machine moves through our contact page — we'll recommend a specific power level instead of overselling you wattage you won't use, and we'd rather you bought the right machine than the more expensive one.
