The RSB140 cordless backpack vacuum cleaner from Numatic International is suitable for a wide range of commercial vacuuming applications around office spaces, congested areas, busy pedestrian zones and is perfect for cleaning aboard buses or even commercial aircraft. As the RSB140 is powered by a 36V battery rather than a mains power supply, there are no wires to restrict access to anywhere, making it extremely versatile. Worn like a back pack, this lightweight vacuum can go pretty much anywhere you can access, so it can even be used on stairways or up ladders. Featuring an easy to reach 'fly-lead' on off switch for safety and a easier user experience, the RSB140 comes complete with an accessory kit to get you cleaning straight out the box.
