One Thing Only:
Making Vacuum Motors Right

Founded in Suzhou in 2020, we make only the motor inside vacuums, floor scrubbers and polishers. Nothing else — so specs, processes and yield rates are all built around one thing.

All Our Focus
on One Motor

The motor inside vacuums, floor scrubbers and polishers. Two product lines: high-speed BLDC fans 120–240W, AC universal motors 550–1400W, covering all mainstream models from cordless handheld to wet & dry canister.

Nothing else, so every process and yield rate is built around this: winding, dynamic balancing, bearing selection, and the test bench every unit passes before shipping.

We are not the largest motor factory, but we are the one that makes only this motor.
