Wet n dry vacuum cleaner

When sourcing for commercial or industrial use, prioritize Suction Power (measured in kPa) and Airflow (CFM). For heavy-duty tasks, a suction power of ≥20kPa is recommended. Additionally, evaluate the Tank Capacity, typically ranging from 15L to 80L; stainless steel tanks offer superior corrosion resistance for wet waste, while high-impact plastic tanks provide lightweight portability. Ensure the motor is a bypass-cooled type to prevent water from entering the motor housing during wet pickup.

For professional environments, a HEPA H13 filter is crucial as it captures 99.97% of particles as small as 0.3 microns, ensuring compliance with air quality standards. For wet applications, verify the inclusion of a washable foam filter or a float valve system that automatically shuts off suction when the tank is full to prevent motor damage. If sourcing for construction, look for M-Class or H-Class certification to meet silica dust safety regulations.

Check for an IPX4 waterproof rating or higher to ensure the machine can handle splashes from any direction. The power cord should be heavy-duty (SJT or H05VV-F) and at least 8-10 meters long for industrial reach. Furthermore, look for overheat protection (thermal cut-off) and anti-static hoses to prevent shocks when vacuuming fine dry dust in low-humidity environments.

In automotive detailing, a compact design with specialized crevice tools and a blower function is preferred. For hospitality and large venues, low noise levels (<75dB) and non-marking rubber wheels are essential to avoid disturbing guests and damaging floors. In industrial workshops, a synchronized power socket (Auto-start) is a high-value feature that allows the vacuum to turn on/off automatically when a connected power tool is used.

The biggest risk is voltage and plug incompatibility. Always specify the target market's voltage (e.g., 110V/60Hz for North America, 220V/50Hz for Europe/Asia) and plug type in the contract. To mitigate quality risks, use Made-in-China.com's Secured Trading services and request a Pre-Shipment Inspection (PSI) to verify that the vacuum's suction and water-lift height meet the advertised specifications.

Suppliers on Made-in-China.com often offer OEM/ODM services. Negotiate for custom branding (logo printing) and color customization at MOQs of 200-500 units. For bulk orders exceeding 1,000 units, aim for a 10-15% price reduction or request the inclusion of extra consumable sets (filters, carbon brushes, and floor nozzles) to increase the total value of the deal.

Ensure the products carry CE, GS, or ETL certifications depending on your region. For the European market, RoHS and REACH compliance for plastic components is mandatory. Be aware of Anti-Dumping Duties that may apply to certain household appliances in specific countries; always check your local Harmonized System (HS) Code (typically 8508.11 or 8508.19) for accurate tariff calculations.

Since vacuum cleaners are high-volume goods, Sea Freight (FCL or LCL) is the most economical method. To optimize costs, ask the supplier to provide SKD (Semi-Knocked Down) packaging, which reduces the box volume by detaching wheels and handles. For urgent samples, use Air Express, but ensure the supplier uses vacuum-sealed packaging for filters to save space.
