Numatic RSB150NX 36V Cordless Backpack Vacuum
The Numatic RSB150NX supports everyday dry cleaning where a trailing mains lead would restrict movement. Its backpack format is useful around seating, along corridors and inside suitable transport interiors.
Numatic’s RSB declaration lists EN 60335-1, EN 60335-2-69, EN 62233, EN 55014-1 and EN 55014-2. The instructions also identify clause 20 of EN/IEC 60335-2-69 for stability and mechanical hazards. These are manufacturer declarations, with the exact editions retained in the specifications.
Cordless Power with Accessible Controls
The 36V NX300 system drives a 350W digital brushless motor. High and low settings are selected from the hand control, keeping operation accessible while the machine is worn.
Numatic’s product specification rates runtime at up to 50 minutes on high or 80 minutes on low per battery. Working conditions, ambient temperature and battery condition affect runtime, so plan charging and battery changes around the cleaning task.
Adjustable Harness and Bagged Collection
The adjustable harness and breathable mesh panel help the operator establish a suitable fit. Waistbelt storage keeps smaller tools accessible while the hose and selected attachment are guided around the work area.
The 5-litre collection system uses TriTex filtration and NVM-1AH HepaFlo bags for ordinary dry material. Inspect consumables regularly and maintain the air path so the machine is prepared for the next cleaning round.
The 5-litre collection system uses TriTex filtration and NVM-1AH HepaFlo bags for routine dry debris. Keep compatible consumables available and maintain the air path.

Directions for Use
- Inspect and prepare: Read the instructions and inspect the machine, hose, tools and battery. Fit a serviceable NVM-1AH bag and the correct filter before installing a charged battery. Use indoors and keep the equipment dry.
- Adjust the fit: Set the harness height and straps so the vacuum sits straight and level. Check clearance around seating and doorways, select a suitable floor or detail tool, and assess safe access before working on stairs.
- Select the power setting: Use the hand control to choose high or low. Work systematically and switch off before exchanging batteries. Do not collect liquids, hot ash, biological hazards, hazardous dust or explosive dust.
- Maintain and recharge: Remove the battery before maintenance. Check tools, tubes and hose for blockage, then the bag and filter. Charge batteries with the correct original Numatic charger, following its instructions. Store dry and do not use damaged batteries or chargers.
