Which is better for cleaning carburetor parts?

The Granbo. Its 400W power, 1000W heater and long timer handle heavy grease and metal parts well. The CREWORKS will work too but heats slower.

Which is gentler on jewelry and delicate parts?

The CREWORKS. Its 180W gentle mode and 40 kHz frequency are less aggressive than the Granbo's 33 kHz at up to 400W.

Is the CREWORKS worth the extra $45?

Only if weight and a gentle mode matter to you. The Granbo gives more power and heat for less money, but weighs 15.1 kg against 8.2 kg.

Do they have the same tank size?

Yes. Both list a 330 x 300 x 150 mm tank, about 15 L. The CREWORKS basket measures 29 x 27 x 11 cm.

Which heats up faster?

The Granbo, with a 1000W heater against 600W for the CREWORKS. Both top out at 80°C.

Can I leave parts soaking for a long time?

The Granbo's timer goes to 9999 seconds, far longer than the CREWORKS' 99 minute maximum. Neither is built for unattended overnight use.
