What we manufacture
Each product page states the platform range, MOQ and lead time up front, so you can tell in ten seconds whether it fits your programme.
Robot Vacuum Cleaners
A robot vacuum cleaner is an autonomous floor-cleaning appliance that navigates a room, suctions debris and can mop in the same pass. Youwang manufactures robot vacuum platforms from 1,000 to 4,000 Pa suction with LDS laser or gyroscope navigation, 90–170 minute runtimes and optional self-emptying dust collection, at MOQs from 500 units and lead times of 15–20 days..
Specifications and processElectric Spin Scrubbers
An electric spin scrubber is a handheld motorised cleaning brush that rotates interchangeable brush heads at 280–350 rpm to scrub bathrooms, kitchens and outdoor surfaces. Youwang manufactures five spin scrubber platforms from 30 W to 100 W with IPX4 or IPX7 water protection, 2–3 hour runtimes and brush head accessory kits, at MOQs from 500 units and EXW pricing from USD 10–21 per unit at 500+ pieces..
Specifications and processCar Vacuum Cleaners
A portable car vacuum cleaner is a compact cordless handheld vacuum for vehicle interiors, typically delivering 8,000 to 20,000 Pa of suction from a lithium battery. The Youwang CG2 platform produces 150 W of suction power in two modes (8,000 Pa ECO and 20,000 Pa MAX), runs 15–25 minutes per charge, recharges over Type-C in 2.5–3 hours and weighs 510 g, at an MOQ of 2,000 units..
Specifications and process
Pet Water Fountains
A pet water fountain is an appliance that circulates and filters drinking water for cats and dogs. The Youwang platforms separate clean and waste water into two physical tanks — 3 L to 4 L clean and 1.35 L to 3.5 L waste — with infrared-sensor or continuous circulation modes, WiFi app control, 24/48-hour automatic drain cycles and battery life up to 90 days on the P006, at MOQs from 500 units..
Specifications and processFour stages, one campus
Moulding, SMT, assembly and compliance run under the same roof, so a design change reaches the line in the same week — and the board behind a field fault is traceable.
Injection Moulding
17 injection moulding machines producing ABS, PP and PC housings for cleaning appliances, with in-house mould maintenance and custom colours from 500 units..
Capability details
SMT Assembly
8 SMT lines with 7 Yamaha YSM20R placers and a Siemens HS60 line, 0201 and BGA capability, verified by 5 AOI, 3 SPI and 1 X-ray machine in Shenzhen..
Capability details Assembly & Testing
4 finished-product assembly lines with 50+ test instruments: suction, sensor calibration, leak testing, charge cycles and WiFi pairing on every unit..
Capability details Battery Pack Integration
In-house 18650 pack assembly from 7.4 V to 14.8 V with protection boards, plus UN38.3, MSDS, drop and stacking transport documentation for air and sea freight..
Capability details Quality & Compliance
In-line electrical and functional testing plus CE, FCC, RoHS, CCC, PSE and UKCA compliance support; documents reviewable before you order..
Capability details Who we build for — and what each market demands
Home Appliance Brands
Home appliance brands outsource cleaning-appliance manufacturing to keep capital out of tooling and lines while controlling brand, colour and packaging. Youwang manufactures private-label robot vacuums (1,000–4,000 Pa, LDS or gyroscope) and electric spin scrubbers (30–100 W, IPX4/IPX7) on 4 assembly lines producing 600,000+ units a year, at MOQs from 500 units and 15–20 day lead times..
Requirements and partsPet Product Brands
Pet product brands increasingly sell powered appliances, and the hardest quality problem in pet hydration is stale water. Youwang manufactures dual-tank pet water fountains that separate 3–4 L of clean water from 1.35–3.5 L of waste water, with sensor-driven circulation, 24/48-hour automatic drain cycles and up to 90 days of battery operation, at MOQs from 500 units..
Requirements and partsAutomotive Accessory Brands
Automotive accessory brands need compact, dry-pickup vacuums that survive a hot car and charge from the same Type-C cable as a phone. The Youwang CG2 platform delivers 8,000 Pa (ECO) and 20,000 Pa (MAX) modes from a 150 W motor, runs 15–25 minutes per charge, weighs 510 g and carries CE, RoHS, FCC and KC documentation, at an MOQ of 2,000 units..
Requirements and partsRetail & E-commerce Programs
Retail and e-commerce programs differ from brand launches in one way: volume and repeat cadence. Youwang produces 600,000+ units a year across four appliance platforms with documented 20GP/40HQ container loading quantities per model, retail-ready colour boxes packed 2–36 units per carton, and repeat-order lead times of 15–20 days on approved configurations..

Read case studyWhat the factory actually looks like
Procurement teams get burned by suppliers whose website shows a showroom and whose shop floor is outsourced. Our facility pages list the equipment — 8 SMT lines with Yamaha YSM20R placers, 17 injection machines, 4 assembly lines and 50+ test instruments — so you can verify before you fly.
Sourcing reference, written for appliance buyers
Certifications, battery documents, MOQ mechanics and spec-sheet honesty — the questions that come up before a purchase order, answered with numbers rather than adjectives.

Read articleOrdering, lead times and documentation
What is your minimum order quantity?
It depends on the platform and configuration: 500 units on entry robot vacuum and pet fountain platforms, 1,000 units on LDS and self-emptying configurations, and 2,000 units on the car vacuum where aluminium finishing and fixed toolings are involved.
What is your production lead time?
15–20 days from deposit and packaging approval for standard configurations. First orders with custom colours or packaging run to the upper end because of the surface-treatment step.
Can you ship under our brand with our own app?
Yes. Housings are injection moulded in-house, so Pantone-matched colours carry no tooling surcharge, and the white-label WiFi app carries your brand name with Alexa and Google Assistant voice integration.
What certifications and test documentation do you have?
CE, FCC (with an FCC ID on file for the WiFi water dispenser platform), RoHS, CCC, PSE and UKCA documentation exists per product family, and every 18650 battery pack ships with UN38.3 and MSDS files. Documentation is available for review during supplier qualification.
What are your payment terms and incoterms?
30% deposit and 70% before shipment. We ship FOB Shenzhen by default, with EXW and DDP available by agreement.
Can I visit the factory before placing an order?
Yes, and we would rather you did. The plant is in Bao'an District, Shenzhen — a 5,000+ m² three-storey building where you can walk the injection moulding floor, the 8 SMT lines and the 4 assembly lines in one visit. Video audits are available if travel is impractical.
