This dust collection bag with a moulded plastic cover plate is a replacement filter bag for robot vacuum auto-empty docks, cordless stick vacuums and commercial vacuum bins. It captures fine household dust at PM2.5 level, together with dust mites, pollen and hair, using a multilayer composite PP (polypropylene nonwoven plus meltblown) and antibacterial filter cotton. It is made by Jyntrel for appliance makers, vacuum brands and aftermarket suppliers who need a bag matched to a specific dock or bin geometry. The bag is built for the exhaust path: low resistance through the media, high dust holding, and a slide handle that closes the bag on removal.
In an auto-empty dock the bag sits downstream of the bin and upstream of the dock fan. When the dock runs its empty cycle, the bag sees a short, high-velocity burst rather than a steady flow. The media therefore has to pass that burst without collapsing, and it has to keep passing it as the bag fills. A multilayer PP meltblown structure gives the fine-fibre layer mechanical support on both sides, so the pleat-free bag wall stays open under pressure pulses and the motor does not have to work against a rising pressure drop.
In a stick vacuum or a commercial bin the pattern is different: longer run times at moderate velocity, with coarse debris arriving first. High porosity in the composite keeps initial resistance low, and the same high dust holding capacity means resistance climbs slowly across the service interval. Because the cover plate is a rigid injection-moulded part, the bag seats flat against the dock port; the interface does not deform when the dock pulls vacuum, which keeps leakage at the gasket line to a minimum.
Environment matters as much as airflow. In humid rooms the PP composite resists moisture take-up better than paper-based bags. The slide handle is operated by hand at change-out, so the bag closes before it leaves the dock and captured dust does not re-enter the room air.
Bag selection starts with the dock, not the bag. Send the device model, or a drawing or sample of the cover plate with its clip positions and port opening. Then tell us the airflow the dock fan delivers during the empty cycle and the expected dust load per cycle. Operating conditions complete the picture: room humidity, typical debris (fine dust, pet hair, sand), and whether odour control is required. From that we propose media grade, bag volume and plate format, and confirm with samples before tooling.
Dimensions and the cover plate are 100% customised to the equipment. We tool rigid cardboard collars and eco plastic injection-moulded plates, and can add the sliding self-seal and an activated-carbon odour-control layer. Logo printing, retail packaging and carton design are part of the same customisation scope.

Jyntrel runs multiple automated production lines with monthly output reaching millions of pieces, and has exported filtration products to Europe, the United States, Japan and Korea for more than 20 years. That combination supports stable supply when a dock programme scales. Production takes place in a 50,000 m² plant in Zhongshan, Guangdong, China, including 6 clean workshops totalling 20,000 m², which limits dust and fibre cross-contamination during bag assembly.
Quality control follows IQC, IPQC and OQC stages from incoming media to packed cartons. The in-house laboratory is CNAS-accredited and can issue reports on filtration efficiency, dust holding capacity and airflow resistance. The company holds ISO 9001, ISO 14001 and ISO 45001 certification and has held IATF 16949 since 2024. Materials meet REACH and RoHS requirements and compliance documents are available. More than 1,000 filtration solutions have been developed to date, which is the basis for our OEM/ODM work on dimensions, structure, media grade, collar material, logo and packaging.
To quote accurately, send us the device or vehicle model, the cover plate size or a drawing, the airflow during the empty cycle or the water flow if relevant to your system, the operating conditions (humidity, debris type, temperature) and the quantity you expect per order and per year. Our engineering team will respond with a proposed media grade, plate format and sample plan. Start here: contact Jyntrel.
Yes. The multilayer PP meltblown composite is supported on both faces, so the bag wall stays open through the short high-velocity burst of an auto-empty cycle. Initial resistance is low and rises slowly as the bag fills, so the dock fan keeps its collection suction across the service interval.
Send the airflow the dock fan delivers during the empty cycle, the expected dust load per cycle, and the room conditions such as humidity and typical debris. A drawing or sample of the cover plate with clip positions and port opening completes the picture, and we then propose media grade and bag volume.
Dimensions and the cover plate are 100% customised to the equipment. We tool rigid cardboard collars and eco plastic injection-moulded plates, and can add a sliding self-seal and an activated-carbon odour-control layer. Logo, retail packaging and carton design are included in the same scope.
The multilayer composite PP construction intercepts PM2.5-level fine dust together with dust mites, pollen and hair, and the sliding handle closes the bag on removal to prevent secondary contamination from the exhaust. Each batch is checked at our CNAS-accredited laboratory for filtration efficiency, dust holding capacity and airflow resistance.
Yes. We confirm media grade, bag volume and plate format with samples before tooling, using your drawing or a sample of the existing cover plate. Share your device model and operating conditions through the contact page and the engineering team will set up the sample plan.
Standard specifications typically start at 5,000-10,000 pieces, while customised products are agreed according to specification complexity. Standard stock orders ship in about 7-15 days; customised orders including tooling usually take 30-45 days, confirmed at order placement.
Replace the bag when the dock or vacuum indicates a full bag, or when suction noticeably drops, which depends on dust load and cycle frequency in your application. The high dust holding capacity extends the interval, and the sliding handle seals the bag so change-out stays clean.
Our bag library covers docks for iRobot Roomba (i, j and s9+ series), Shark, Roborock, Ecovacs, Xiaomi and Dreame models, and we can supply a compatibility list. For a new model our engineers can complete sampling within 2-3 weeks of receiving the device. Tell us your model and conditions via <a href="/en/contact">our contact page</a> to start an inquiry.
