This battery-powered vacuum cleaner features a domestically pioneered detachable tank design for easy cleaning. It uses a lithium battery as the power source, with three DC bypass motors providing strong suction. One charge can provide 3-4 hours of continuous use, and it works with a high-quality intelligent charger, making it the ideal choice for cleaning in factories, properties and other places. The cordless design greatly improves work efficiency, completing suction of dust, iron filings, water, welding slag and metal particles in one pass. The metal motor head is a luxurious head with good heat dissipation; the 1500W strong suction can handle both dust and water for dry and wet use. The battery pack uses a lithium battery as the power source, with a 100Ah large-capacity battery providing a runtime of up to 3-4 hours. It is a major brand, offering more stable performance. The filtration system adopts primary filtration with polyester non-woven fabric combined with a high-efficiency HEPA filter, with a filtration area of up to 25000cm², effectively filtering 0.3 micron dust at 99.9%. The dust collection tank is a 100L upper-lower detachable tank; simply pull the handle to take out the dust bucket, fast and convenient. The suction inlet adopts a 76mm-to-50mm aluminum die-cast inlet with stainless steel reducer, and the hose never kinks. The cyclone separator side-suction design combined with the cyclone separator effectively reduces clogging and prevents liquid, dust and iron filings from blocking or damaging the filter.
