Battery Battle: BackPack vs Tub…

OSCS News 23-Jan-24 | By Steve

It appears that we are increasingly inhabiting a world without cords, where the allure of cordless convenience significantly impacts our purchasing decisions.

This trend extends to the realm of vacuuming. Cordless vacuum cleaners have gained immense popularity, particularly in commercial settings where time is at a premium.


Battery-powered vacuum cleaners do away with the need to search for power outlets, fostering a safer environment by consigning cords and their tripping hazards to history.

The advantages of cordless vacuum cleaners are evident, but have you pondered how these benefits can be significantly amplified when you introduce a backpack-style model into the cordless vacuum landscape?

Cordless backpack vacuum cleaners harness all the benefits of battery-powered vacuum cleaners and seamlessly meld them with the inherent merits of the backpack design. These merits encompass effortless manoeuvrability, enhanced control, user comfort, ergonomic design, and the ability to effortlessly clean confined spaces, reaching nooks and crannies, as well as areas like stairwells and elevators with ease.

Whilst a battery-powered vacuum may entail a slightly higher initial investment than a traditional corded-cleaner, many models are poised to recoup their costs within a few months, thanks to the substantial labour and time savings they offer.

The NX300 battery which features in both these vacuums now has a 3 year warranty.

Our two options for this battle are both from Numatic, and are the RSB150NX BackPack Vacuum, and the NBV240NX Tub Vac

RSB150 2 batteries

Numatic RSB150NX

This is the newest in Numatic’s battery backpack vacuum lineup and is equipped with their new NX300 36V Battery Technology and 350W digital brushless motor.

Delivering up to 80 minutes of cordless freedom, a 40% increase in airflow and suction, and maximum user comfort, the RSB150 provides optimum cleaning productivity with powerful and professional cleaning results.

The new backpack harness has been ergonomically designed with easy-adjust, posture-correcting harness and handy tool storage. Simple, integrated hand control, providing optimum user-comfort, meaning less stretching, bending down, twisting and full control always. The breathable mesh panel allows air to flow and to keep the user cool and comfortable.

With no cables – minimise the risk of slips, trips, and falls to the operator and the public.

Ideal for day cleaning and public areas with high footfall such as retail stores and public transport, or workplaces with plenty of stairs!

Numatic NBV240NX

This Numatic NBV240NX tub vacuum is equipped with the same NX300 battery and 350w motor as the backpack vacuum and also delivers up to 80 minutes of cordless cleaning and a 40% increase in airflow and suction from a compact, convenient and versatile design.

The NBV240NX is perfect for day cleaning and safe operation in public areas, maximising productivity with powerful and professional cleaning results.

The biggest difference between the two, is the capacity. With this tub vac featuring a 9L capacity, compared to the backpack version which only has 5L. This means more cleaning time without stopping to find somewhere to empty!

Check out the product page for more details.

On comparison you can see that it’s extremely close between the two machines, so it comes down to personal preference.

Do you need a larger capacity? The Tub vac is the best option for you.

Do you need to quickly traverse all those stairs? If so, the Backpack version maybe better…
