Granbo ultrasonic cleaners
Granbo's catalog contains several lines with similar tank capacities and different controls. This collection starts with two manager-verified capacity listings, while keeping their manufacturer SKU mapping and usable dimensions unresolved. The useful comparison is the exact supported setup, not the largest liters label.

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.
