| Battery Chemistry | Lithium-ion rechargeable battery, commonly using cylindrical or pouch cells | Provides higher energy density and lower weight than many traditional rechargeable battery formats. | Review the battery datasheet, cell type, production batch records, and safety test reports. |
| Nominal Battery Voltage | Approximately 18 V to 25.2 V for many cordless household models | Higher voltage can support stronger motor performance, but may increase component and certification requirements. | Confirm nominal voltage, maximum charging voltage, motor rating, and charger compatibility. |
| Battery Capacity | Usually about 2.0 Ah to 4.0 Ah; energy is approximately 36 Wh to 100 Wh depending on voltage and capacity | Capacity affects operating time, shipping classification, product weight, and replacement-battery cost. | Calculate watt-hours using Wh = nominal volts × amp-hours and compare with measured capacity. |
| Operating Time | Approximately 20 to 60 minutes per charge, depending on power mode and attachment | Longer runtime improves user convenience but normally requires a larger battery or lower motor power. | Conduct runtime tests in standard, high-power, and floor-head modes using a fully charged battery. |
| Charging Time | Commonly about 3 to 5 hours with a standard charger; faster charging depends on battery design | Charging speed influences customer satisfaction and may affect charger thermal performance. | Measure full charging time, charger output, charging temperature, and automatic charge termination. |
| Suction Performance | Performance should be compared using consistent airflow, suction pressure, and cleaning-load tests rather than motor wattage alone | Motor wattage by itself does not accurately indicate cleaning effectiveness across different designs. | Request measured suction pressure, airflow data, and independent tests on hard floors and carpets. |
| Filtration System | Multi-stage filtration is common; some models include a washable fine-particle filter | Effective filtration can reduce particle re-emission and supports different household and regional market requirements. | Check filter material, sealing design, replacement interval, airflow restriction, and particle-retention test results. |
| Dustbin Capacity | Approximately 0.3 L to 0.8 L for many lightweight cordless models | A larger dustbin reduces emptying frequency but may increase product size and shipping volume. | Verify usable capacity, emptying mechanism, dust leakage, and cleaning access during inspection. |
| Product Weight | Approximately 1.5 kg to 3.5 kg for the handheld or stick-vacuum configuration | Lower weight improves portability, ergonomics, and suitability for frequent cleaning. | Weigh production samples with the battery, dustbin, filter, and standard floor head installed. |
| Battery Management System | Protection against overcharge, over-discharge, short circuit, overcurrent, and abnormal temperature | A reliable battery management system reduces safety risks and helps maintain battery life across different climates. | Review circuit diagrams, protection thresholds, thermal sensors, and fault-condition test records. |
| Battery Cycle Life | Often specified at approximately 300 to 800 cycles, depending on cell quality, depth of discharge, and operating conditions | Cycle life affects warranty exposure, replacement demand, and long-term ownership value. | Request cycle-test conditions, remaining-capacity criteria, sample size, and laboratory records. |
| Global Transport Requirements | Lithium batteries are regulated as dangerous goods for many air and sea shipments | Incorrect documentation or packaging can cause shipment delays, extra fees, or customs problems. | Confirm UN 38.3 test summary, battery classification, packaging instructions, labels, and transport documents. |
| Electrical and Product Safety | Household vacuum cleaners commonly require assessment against applicable IEC 60335 safety requirements | Safety compliance supports market access and reduces the risk of recalls or rejected shipments. | Obtain test reports for the complete vacuum cleaner, charger, battery pack, insulation, heating, and abnormal operation. |
| Battery Cell Safety | Rechargeable lithium cells and batteries are commonly evaluated under IEC 62133-2 or equivalent local requirements | Cell-level safety evidence helps assess thermal, mechanical, and electrical abuse resistance. | Check cell certification scope, test laboratory accreditation, traceability, and consistency between samples and production. |
| Charger Compatibility | Input voltage may be designed for a specific region, while some chargers support approximately 100 V to 240 V AC | Regional charger compatibility simplifies international sourcing and reduces the number of product versions. | Verify input range, plug type, output voltage, efficiency, temperature rise, and local electrical approvals. |
| Environmental Compliance | Material and chemical compliance may include RoHS, REACH, battery-marking, and recycling obligations, depending on the destination | Requirements vary by market and can affect materials, labels, documentation, and end-of-life responsibilities. | Prepare a destination-market compliance checklist and review declarations, material records, and technical files. |
| Replacement Parts | Key service parts include batteries, filters, chargers, brush rolls, adapters, and dustbin components | Accessible replacement parts improve after-sales support and extend product service life. | Confirm part availability, lead times, interchangeability, packaging, and service instructions before placing an order. |
| Quality Control Priorities | Critical checks include battery capacity, charging behavior, suction performance, noise, assembly fit, and electrical safety | A product-specific inspection plan helps control performance variation between samples and mass production. | Use an approved sample, defined acceptance criteria, production inspection, and random pre-shipment testing. |
