Baoxing Custom Lubrication Solutions Help Home Appliance Manufacturers Improve Quality & Efficiency


As the smart home cleaning industry continues to boom, robot vacuums have become essential household appliances, driving a new wave of mass production and quality upgrading across the sector. The planetary gear reducer acts as the core power unit of the robot, operating under frequent start-stop cycles, alternating high and low temperatures, and continuous heavy-load conditions. Its lubrication performance directly determines the robot’s noise level, battery efficiency, and overall service life, making professional grease selection a key factor for brand quality iteration.


Planetary reducers in robot vacuums must perform reliably under extreme working conditions, including smooth cold startup at -25°C and long-term thermal endurance up to 200°C. Continuous high-speed gear meshing friction inevitably leads to tooth surface wear, transmission stuttering, and gradually increasing abnormal operating noise. In addition, the precision hybrid structure of plastic and metal gears requires lubricants to meet strict environmental safety standards and long-term stability requirements. Ordinary greases quickly lose their noise-dampening effect, increase running resistance, and accelerate gear wear over time. This results in loud operational noise, shortened reducer lifespan, and failure to meet the original 5–10 year long-term service design standard.


Targeting the core lubrication pain points of robot vacuum planetary gearboxes, Baoxing launches two tailor-made professional lubrication solutions:

BX-303/3(A)-WY Multi-Purpose Noise-Reduction Grease (Low-Viscosity Formula)Features strong adhesion and excellent shock-absorbing performance.

It effectively reduces gear meshing noise and mechanical wear, ensuring smooth and jitter-free startup even in low-temperature environments.

BX-800/C-WY High-Temperature Noise-Reduction GreaseDelivers extreme wide-temperature performance, maintaining stable lubrication from -25°C to 190°C.

It resists high-temperature oil bleeding, provides waterproof protection, and prevents corrosion inside the gearbox.

Both Baoxing lubricants offer outstanding permeability and long-lasting oil retention, keeping the entire planetary gear reducer running smooth, quiet, and stable for years.


With 20 years of expertise in domestic specialty lubricant manufacturing, Baoxing focuses on custom industrial lubrication solutions for the home appliance industry. 

Both BX-303/3(A)-WY and BX-800/C-WY fully comply with RoHS and REACH environmental standards, supporting global export requirements. The performance of Baoxing greases matches well-known imported brands, realizing reliable and cost-effective domestic substitution.

Baoxing provides free sample testing, personalized formula customization, and one-on-one full-process technical support. 

We help robot vacuum manufacturers pass strict lifespan reliability tests, achieve stable 5–10 year equipment operation standards, greatly reduce after-sales repair rates, 

and enhance core product competitiveness in the global smart home market.
