Do not choose between Granbo lines by capacity alone
Granbo's official catalog contains GS0306, GW0306, GX0306 and GT0306 entries with similar nominal capacities but different control descriptions. A matching 6.5 L label does not establish which features or manual apply to this ASIN. We therefore keep the public product identity tied to the verified Amazon listing rather than assigning an unconfirmed SKU.
A search snippet suggested GW0306, but the underlying exact product page was not readable through the permitted source. We do not treat that incomplete record as enough to transfer heater ranges, dimensions or power modes.
The next useful measurement is the basket
For a larger part, obtain usable length, width and immersion depth before ordering. For a batch of smaller parts, consider the supported arrangement rather than assuming everything can be piled into the advertised volume. Neither case can be resolved from liters alone.
The title also includes 180 W without clarifying the measurement basis in the manager response. We retain that as a listing claim, not a tested output or a number to add to heater power. This page does not rank cleaning strength from unspecified wattage.
When to keep it on the shortlist
Keep this candidate if you can verify that the exact model supports your cleaning procedure and provides sufficient basket room. Move to a documented alternative if the necessary details remain unavailable. A larger machine would be wasted if your main obstacle were material compatibility rather than space.
Confirm the voltage, supplied accessories and operating instructions on the selected offer. No manual from a visually similar model should be used to improvise solvent, temperature or runtime settings. Our assessment identifies the decisions still to make; it does not claim hands-on cleaning tests or a guaranteed match.
Before you choose
- Exact manufacturer SKU is not confirmed.
- Working fill, basket dimensions and heater range remain unknown.
- 180 W is listing wording, not an independently measured output.
