Granbo ultrasonic cleaners
Granbo offers several cleaner families with similar capacities. The two listings below differ in nominal size and advertised controls, but neither has a confirmed manufacturer model match. Compare what is stated and identify the manual and basket measurements still needed before purchase.

How to choose within the range
The 3.2 L and 6.5 L listings are distinct Amazon records, but capacity alone does not identify the corresponding GS, GW or other manufacturer line.
Ask for a nameplate model and matching manual before relying on a heater range, power mode or continuous-use claim.
Usable basket geometry is unconfirmed for the selected listings. The finder must keep them out of guaranteed-fit results.
Some official catalog pages contain inconsistent capacity or product-name fields. Preserve uncertainty instead of borrowing the most favorable number.
Tri-frequency, knob-operated and larger models remain research candidates until exact identity and operating evidence improve.
