8 Robot Vacuum Manufacturers in China (2026)

Search “robot vacuum manufacturers china” and the results split into two groups: household names you see on Amazon and anonymous Shenzhen ODMs that actually build a share of the white-label robots sold under Western brands. The real question for a buyer is not who has the best-known consumer brand, but who will take your BOM, stick to the navigation spec, and ship a cert-ready product.

The supply base clusters in two places. Shenzhen and the Pearl River Delta host the ODM/OPM houses and the navigation-module ecosystem; Suzhou and Jiangsu are home to the large listed groups such as Ecovacs and Dreame. OEM/ODM pricing runs roughly $40–$200 at factory-exit depending on whether the unit uses random/gyro, vSLAM camera, or LDS LiDAR navigation, and whether it includes a self-cleaning mop station. The most common mistakes I see are paying LDS money for a vSLAM unit, treating a brand’s retail product as proof it accepts small OEM orders, and accepting a “series” certification that does not cover the exact model being shipped. Our robot vacuum OEM guide covers the technical vetting in more detail; this article is the factory shortlist.

I have sorted the list by scale and OEM openness, not by brand fame. For each entry I note what they actually build today, whether they still accept OEM, and where they sit on the LDS-vs-vSLAM map.

Quick comparison

How we evaluate

We score robot vacuum factories on six points:

1. Certification scope. CE, FCC, UKCA, and RoHS test reports must match the exact model, navigation configuration, and power supply you are buying. Generic “series” certificates are common in this category and often do not cover your SKU. Check CE Declarations against the EU’s CE marking framework.
2. Navigation technology. LDS LiDAR gives accurate mapping and works in the dark, but costs more and needs a taller deck. vSLAM uses cameras and is cheaper and slimmer, but struggles in low light. Gyroscopic/random patterns are the lowest tier.
3. Production scale vs. OEM focus. Large brand houses have capacity but are selective. Pure ODMs are more accessible but vary in export maturity.
4. Export experience. Prior shipments to the US, EU, or Japan show the factory understands labeling, documentation, and recall-readiness.
5. Sample-to-mass-production control. Robot vacuums are sensitive to component substitutions — lock the BOM, firmware version, brush motor, and battery cell after sample approval.
6. ODM openness. Some own-brand giants have closed or nearly closed their OEM doors; ILIFE exited OEM in 2024 and Roborock no longer takes third-party OEM/ODM. Treat the current stance as a hard filter.

The top 8 manufacturers

1. Ecovacs Robotics

Ecovacs Robotics is headquartered in Suzhou, Jiangsu, and is one of the largest listed robot vacuum groups in China. It sells the Deebot consumer line and operates a separate OEM/ODM division that builds for external brands at volume.

The engineering strength is in mapping and AI vision: AIVI object recognition and TrueMapping laser-based navigation are used on its premium Deebot models. For a buyer, the trade-off is access — Ecovacs will entertain serious programs rather than small test orders, and it expects buyers to bring distribution scale or a long-term forecast.

Key details:

• Base: Suzhou, Jiangsu
• Listed group with own-brand + OEM/ODM division
• Main lines: Deebot robot vacuums, AIVI/TrueMapping navigation
• Navigation tier: LDS / AI vision
• Typical OEM price band: $100–$200 for mid-to-premium LDS units
• Export focus: US, EU, Japan

Best for: large brands or retailers that need a high-volume, cert-ready manufacturing partner.

Not ideal for: small first orders or buyers wanting deep customization of the PCB layout.

2. Roborock / Beijing Roborock Technology

Roborock is headquartered in Beijing with R&D centers in Shanghai and Shenzhen. It started as a Xiaomi ODM in 2015, de-Xiaomified from 2017, and by 2021 Xiaomi-related revenue had fallen below 1%. Today it is a pure own-brand company focused on premium robot vacuums.

Roborock is not an active third-party OEM/ODM option in 2026. It is on this list as a reference point: its algorithmic LDS navigation, strong suction-to-noise ratios, and dock integration set the benchmark for what a premium Chinese robot vacuum can deliver. Buyers sometimes assume a brand with manufacturing scale will white-label — in Roborock’s case, that assumption is wrong.

Key details:

• Base: Beijing HQ; R&D in Shanghai and Shenzhen
• Main products: LDS robot vacuums, all-in-one dock systems
• Navigation tier: LDS / advanced SLAM
• OEM stance: own brand only
• Typical price band: $120–$200+ (brand retail, not OEM)
• Export focus: US, EU, Japan, Korea

Best for: understanding the premium benchmark and competitive positioning.

Not ideal for: buyers looking for any form of white-label or OEM partnership.

3. Dreame Technology

Dreame Technology is based in Suzhou, Jiangsu, and makes smart home cleaning appliances including robot vacuums and stick vacuums. It shares the same manufacturing corridor as Ecovacs and has built a large supply chain for high-speed digital motors and battery systems.

Dreame is primarily an own-brand play today, with robot vacuums positioned as feature-rich alternatives to Roborock and Ecovacs. Its production scale is real, but external OEM access is limited and typically tied to strategic partnerships rather than catalog white label.

Key details:

• Base: Suzhou, Jiangsu
• Main products: robot vacuums, stick vacuums, high-speed motors
• Navigation tier: LDS / high-suction platforms
• OEM stance: own brand, selective/strategic OEM only
• Typical OEM price band: $100–$180 for mid-range LDS units
• Export focus: Global, strong in Europe and Southeast Asia

Best for: brands that can align with Dreame’s motor and battery technology in a partnership.

Not ideal for: small importers looking for a standard white-label LDS robot.

4. Shenzhen Silver Star Intelligent Technology

Silver Star is one of the largest dedicated robot vacuum ODM/OPM houses in Shenzhen, with more than 1,600 employees. It builds for major home-appliance brands, including SEB and Bissell, and can carry a project from industrial design through final assembly.

Because it is a pure ODM rather than a consumer brand, Silver Star is more accessible than the listed giants for mid-size buyers. The product range spans LDS and vSLAM robots, and the company has the tooling and test labs to support regional certifications.

Key details:

• Base: Shenzhen, Guangdong
• Scale: 1,600+ staff
• Customers: SEB, Bissell, and other home-appliance brands
• Navigation tier: LDS and vSLAM
• OEM stance: ODM/OPM open
• Typical price band: $60–$150
• MOQ hint: 1,000–2,000 units

Best for: mid-to-large brands that need a full ODM partner with Western retail experience.

Not ideal for: very small first orders or buyers who want only a simple logo-swap SKU.

5. Shenzhen Picea Robotics / 3irobotix

Picea Robotics, previously known as 3irobotix, was founded in 2016 in Shenzhen and focuses on robot vacuum R&D and manufacturing. The company specializes in LDS navigation platforms and has supplied major Western brands including iRobot, SharkNinja, and Eufy. In December 2025 the relationship with its biggest customer inverted: following iRobot’s Chapter 11 restructuring, Picea — through its subsidiary Santrum HK — converted debt to equity and took 100% ownership of iRobot, making the former supplier the owner of the category’s best-known brand.

Its relative youth shows in agility: Picea is usually faster to sample than the big brand factories and willing to work with lower MOQs. The caveat is that certification management and export documentation may require more buyer oversight than at a retail-experienced ODM.

Key details:

• Base: Shenzhen, Guangdong
• Founded: 2016
• Main products: LDS robot vacuums
• Navigation tier: LDS
• OEM stance: ODM open
• Customers: iRobot, SharkNinja, Eufy (per public ITC and supply-chain records)
• Typical price band: $50–$120
• MOQ hint: 500–1,000 units

Best for: startups and Amazon sellers launching a first LDS robot vacuum.

Not ideal for: buyers who need turnkey certification for major retailers.

6. ILIFE / Zhiyi Innovation

ILIFE, operated by Zhiyi Innovation, is one of the early Shenzhen pioneers in robot vacuums and built much of its early volume through OEM work. In 2024 the company exited OEM to focus on its own ILIFE brand, so it should not be treated as an active contract manufacturer today.

The current catalog is budget-to-mid robot vacuums, mostly using gyroscopic or vSLAM navigation. For buyers, ILIFE is useful as a reference for what an experienced Shenzhen brand can deliver at low price points, not as a partner for your white-label project.

Key details:

• Base: Shenzhen, Guangdong
• History: early OEM pioneer, exited OEM in 2024
• Main products: ILIFE brand robot vacuums
• Navigation tier: gyro / vSLAM
• OEM stance: brand only
• Typical price band: $40–$90 (brand retail, not OEM)

Best for: buyers studying budget brand positioning and feature sets.

Not ideal for: anyone looking for an active OEM/ODM partner in 2026.

7. Mamibot

Mamibot is a smart cleaning brand whose Asia-Pacific headquarters is in Putuo District, Shanghai (Mamibot Manufacturing (Shanghai) Co., Ltd.). The company sells robot vacuums, window-cleaning robots, and stick vacuums under its own brand globally.

Mamibot is primarily an own-brand company, not a reliable contract manufacturer for third-party robot vacuums. It appears on this list as a category reference for mid-market feature sets, not as a recommended OEM partner. If you see a supplier claiming to be the “Mamibot factory” for white-label production, verify the entity and current OEM policy before paying a deposit.

Key details:

• Base: Shanghai, China (Asia-Pacific HQ, Putuo District)
• Main products: robot vacuums, window-cleaning robots, stick vacuums
• Navigation tier: vSLAM / LDS depending on SKU
• OEM stance: brand only
• Typical price band: $60–$130 (brand retail, not OEM)

Best for: understanding mid-market smart cleaning brand positioning.

Not ideal for: buyers who need a dedicated robot vacuum ODM.

8. Narwal / Cloud Whale

Narwal, also known as Cloud Whale, is a Shenzhen-based brand famous for self-cleaning mop robots that wash their own mopping pads. It created a distinct category around mop-first cleaning and has expanded into vacuum-and-mop combos.

Narwal is an own-brand company, not an open ODM. The technology is relevant because it shows where the self-cleaning dock segment is heading, but you cannot walk in with a white-label request and expect the same access you would get from a Shenzhen ODM.

Key details:

• Base: Shenzhen, Guangdong
• Main products: self-cleaning mop robots, vacuum-and-mop combos
• Navigation tier: LDS + mop AI
• OEM stance: brand only
• Typical price band: $150–$200+ (brand retail)

Best for: brands researching the self-cleaning mop category.

Not ideal for: buyers looking for an OEM partner to produce a generic robot vacuum.

How to verify any supplier on this list

Robot vacuum certifications are easy to fake on paper, and a sample that maps the office beautifully may drift in mass production. Before you pay a deposit, do four things:

1. Match the certificate to the SKU. The CE, FCC, UKCA, or RoHS report must list the exact model name, navigation type, battery voltage, and dock configuration. A “series” certificate that covers ten products is usually not valid for your specific unit.
2. Confirm the navigation hardware. Ask for the bill of materials or a PCB photo. LDS should show a rotating laser module; vSLAM should show a forward-facing camera and sufficient ambient-light handling. Do not pay LDS pricing for a gyro or vSLAM build.
3. Lock the BOM after sample approval. Record the firmware version, brush motor part number, battery cell supplier, and LDS module model. Substitutions in any of these change suction, mapping accuracy, and safety.
4. Audit the production floor. Check whether the factory has dedicated assembly lines, aging test racks, and a dust/suction test station. A hands-on factory audit is the fastest way to separate an assembly trader from a real manufacturer.

Frequently asked questions

Who manufactures robot vacuums for Western brands?

Chinese ODMs and the selective OEM divisions of own-brand giants. Shenzhen Silver Star Intelligent and Shenzhen Picea Robotics (formerly 3irobotix) are pure ODMs that build for Western labels; Silver Star lists SEB and Bissell among its customers, and Picea has supplied iRobot, SharkNinja, and Eufy. Ecovacs runs a genuine OEM/ODM division for external brands at volume. Roborock is a pure own-brand reference today — it does not offer third-party OEM/ODM. Dreame is primarily own brand with selective strategic partnerships. ILIFE exited OEM entirely in 2024, and Mamibot and Narwal are own-brand companies. Geography matters: Shenzhen and the Pearl River Delta host the ODM specialists, while Suzhou/Jiangsu is home to the large listed groups. For a buyer, the practical split is simple: if you need a white-label or ODM partner, start with Silver Star or Picea; if you have the volume to co-develop with a tier-one brand house, Ecovacs is the realistic conversation.

What is the price range for OEM robot vacuums from China?

Factory-exit pricing for OEM/ODM robot vacuums generally falls between $40 and $200. At the low end, gyroscopic or basic vSLAM units with simple dustbins land around $40–$80. Mid-range LDS LiDAR robots with mapping, no-go zones, and app control usually run $80–$150. Premium configurations — LDS with AI obstacle avoidance, self-emptying docks, or self-cleaning mop stations — push $150–$200. The navigation system is the biggest cost driver: adding LDS over gyro can raise the unit cost by $15–$25, and a self-cleaning dock can add $40–$80. MOQs and mold costs sit on top of that, so treat the $40–$200 band as the unit price for an existing platform, not the landed cost of a fully custom project.

LDS vs vSLAM: which navigation do Chinese ODMs offer?

Both. LDS (laser distance sensor, or LiDAR) is the mid-to-premium standard: it maps rooms accurately, works in the dark, and supports multi-floor maps, but it adds cost and requires a taller robot deck. vSLAM (visual simultaneous localization and mapping) uses a camera and is cheaper and slimmer, but performance drops in low light and it can miss dark furniture. Entry-level units may still use gyroscopes or random-bounce patterns. Most Chinese ODMs offer LDS on orders of 500+ units, while vSLAM is common in the $40–$80 OEM band. If your market values mapping accuracy and night cleaning, specify LDS. If the buyer is price-sensitive and the home has good lighting, vSLAM can keep the retail price down.

What MOQ do robot vacuum ODMs require?

MOQs depend on whether you are using an existing platform or adding custom tooling. For standard LDS or vSLAM robots from a Shenzhen ODM, expect 500–1,000 units for a first order. Custom shell colors, packaging, and private-label app skins usually keep the same band. If you need a new mold, a self-cleaning dock, or a flagship LDS+AI configuration, the factory will likely ask for 1,000–2,000 units. Ecovacs typically expects 3,000+ units or program-level volumes for its OEM/ODM division. Roborock does not run third-party OEM/ODM. Silver Star, as a large ODM/OPM, typically sits in the 1,000–2,000 range, while Picea Robotics (formerly 3irobotix) can go lower for startups testing the category.

Final word

The right robot vacuum manufacturer depends on your order profile, not on brand fame. If you need an open ODM for a mid-volume white-label launch, Silver Star or Picea Robotics are the practical starting points. If you can commit container-level volumes and want co-development with a tier-one engineering house, Ecovacs is the realistic conversation. Roborock, ILIFE, Mamibot, and Narwal are on this list as category references — not as default OEM partners — so confirm current OEM policy directly before treating any brand-only company as a supplier.
