techTongBo Launches SourceVCP Guides: A Free Resource Center for Vacuum Parts Buyers
Nanjing, China — November 2026 — techTongBo, a wholesale supplier of replacement parts for robot vacuums, vacuum cleaners and air purifiers, has launched SourceVCP Guides, a free online resource center for distributors, repair centers, ecommerce sellers and private-label buyers.
Why we built SourceVCP Guides
Every week our sales team answers the same questions before a quote can even begin: Does this roller brush fit both the S7 and the S8? How do I find the right part when the customer only knows the model name? What should I check on samples before placing a bulk order?
Good answers to these questions are hard to find in one place. Brand manuals focus on end users, and marketplace listings rarely explain fitment differences between model generations. With 24,580 SKUs in stock and buyers in 103 countries, we have collected a lot of this knowledge internally — SourceVCP Guides is where we now publish it openly.
What buyers will find
The guides are written for people who buy parts in volume and need to get the order right the first time. The first articles cover three areas:
Model compatibility. Side-by-side fitment checks for popular models, such as the Roborock S7, S8 and Qrevo parts compatibility guide and the Tineco S6/S7 Pro and Dyson V8 roller and filter guide.
Quality control. How we approach sample approval, batch inspection and inventory traceability, explained step by step in Robot Vacuum Parts Quality Control: Sample to Shipment.
Sourcing basics. Practical help for newer buyers, from identifying replacement parts by model name to evaluating suppliers and arranging shipping.
How it connects to our service
SourceVCP Guides does not replace talking to our team — it makes that conversation faster. Buyers who check fitment and quality requirements in advance can send a precise inquiry, and we can respond with matching SKUs, samples and pricing sooner.
New guides will be added regularly, with a focus on the models and part categories our customers ask about most: roller brushes, side brushes, HEPA filters, mop pads, dust bags and cartridges.
“Building a digital content platform from scratch — one that we fully own and control — may be a step we are taking a little late, but it is a step worth working hard to take,” said Ma Lu, Head of Business at techTongBo. “Going forward, our team will keep publishing valuable content on this platform to help more entrepreneurs and business owners around the world.”
