For professional cleaning equipment, product quality is not only determined by how a machine performs when it leaves the factory. What matters equally is whether every machine can be identified, every key component can be traced, and customers can continue to receive reliable after-sales support after delivery.
At YISHENG, strict quality control and standardized shipment procedures are applied throughout the production and delivery process to ensure that every machine supplied to our customers has a clear identity and a traceable service record.
Strict Quality Control Before Shipment
Before shipment, YISHENG machines undergo a series of inspections and functional tests covering key systems such as cleaning performance, water circulation, electrical control, motor operation, battery system, charging system and overall machine operation.
Our quality control team carefully checks the machine condition before packing to ensure that the equipment meets the required production and delivery standards.
Shipment is not simply a matter of packing the machine and sending it out. Each unit is inspected, confirmed and recorded before it leaves our factory.
Metal Nameplate with Unique Machine Code
Each YISHENG machine is equipped with a durable metal nameplate.
The nameplate contains the machine identification information, including a unique machine code / serial number.
This machine code serves as the identity of the equipment throughout its service life.
Through the machine code, YISHENG can trace relevant production and after-sales information, helping our team identify the machine accurately when customers require technical support, spare parts or warranty service.
This traceability system is especially important for distributors, rental companies, facility management companies and customers operating multiple machines.
One-Year Warranty for Core Components
YISHENG provides a one-year warranty for major core components, including key parts such as:
-
Motors
-
Electronic control systems
-
Batteries
-
Other major electrical and functional components covered by the warranty terms
If a technical problem occurs during the warranty period, our after-sales team can identify the machine through its serial number, review the relevant information and provide corresponding technical support or warranty solutions according to the actual situation.
Traceable After-Sales Support
Professional equipment should not become unsupported once it has been delivered.
YISHENG maintains machine identification and relevant service information so that after-sales support can be continuously tracked.
Whether customers need troubleshooting assistance, replacement parts, maintenance guidance or warranty support, the machine code allows our team to identify the corresponding equipment and provide more accurate support.
For overseas distributors and long-term partners, this system also makes fleet management and spare-parts support more efficient.
Quality Is a System, Not a Slogan
A reliable cleaning equipment supplier requires more than products and quotations.
It requires standardized production, quality inspection, machine identification, shipment records, spare-parts support and a responsible after-sales system.
From strict factory inspection to metal identification plates, from unique machine codes to one-year warranty coverage for core components, YISHENG continues to build a more standardized and traceable quality management system.
Our goal is simple:
Every machine has an identity.
Every shipment has a standard.
Every after-sales request can be traced.
Every customer can find the responsible team behind the product.
YISHENG is committed to providing professional cleaning equipment with reliable quality, standardized delivery and long-term after-sales support to customers around the world.
