The ML‑B009 2‑in‑1 cordless blower vacuum handles heavy‑duty yard and workshop jobs effortlessly. Switch between blow mode for clearing fallen leaves and suction mode for collecting dust & debris.

Powered by a 3820 brushless 400W motor, this lightweight 21V power tool is built for long‑time use. But even robust blow‑vac units will suffer premature wear without regular upkeep — especially the suction passage which easily clogs with leaves, wood chips and dust. Below is complete maintenance guidance for end‑users, contractors and B‑side distributors.

Quick Reference: ML‑B009 Key Specifications

Regular cleaning of both blowing and suction channels keeps performance stable.

✅ After‑use Routine (Critical for 2‑in‑1 Blower Vacuum)

1. Clean air‑inlet grilleRemove stuck leaves, sawdust and debris. Blocked intake will cause motor overheating and reduced power.

⚠️ Never wash the machine with water. Use dry brush or compressed air only.

2. Clear suction & blow passagesWhen you frequently use suction function, debris may jam inside the internal channel. Detach nozzle and suction adapter, clear clogs completely. Blockage will hurt both blowing and suction performance.
3. Check dust collection bag / portIf you work under suction mode, empty and clean the dust collecting bag after each job. Do not run suction with a full bag.
4. Wipe outer housingUse soft dry cloth to wipe dust and grease off shell and handle.
