Corded floor scrubber: the alternative when a battery is not needed
Choosing a corded power supply offers real advantages over a battery-powered scrubber dryer: the purchase price is 20 to 35% lower than an equivalent battery-powered machine, and the corded power supply allows for greater power development, resulting in higher brush motor torque and more powerful suction, at the cost of a noisier machine and reduced freedom of movement due to the cord. However, this point should be put into perspective: in most cases, the layout of the premises and the availability of sufficient electrical outlets make this a minor inconvenience.

Case of self-propelled and autonomous robotic floor scrubbers
Of course, in the case of ride-on machines (ride-on scrubber-dryers) or robotic machines, a battery is essential. You will never see this type of machine with cable power supplies.
New generation Numatic NX1K and NX300 Lithium batteries
Numatic, like Nilfisk and Taski, now equips all its new compact scrubber-dryers and even ride-on scrubber-dryers with Lithium batteries which offer many advantages and thus reduce the handicap of old lead or gel batteries versus cable models.
These new batteries offer fast charging , longer lifespan and flexible power thanks to their modular design.
The NX1K battery, featured on ride-on scrubber dryers, brings the latest lithium technology to the battery-powered scrubber dryer range, offering extended runtime with faster, more flexible charging and long-lasting power while delivering the same professional results and reliability. It boasts a lifespan four times longer than lead-acid batteries. Advanced and safe lithium-phosphate technology provides 4,000 charge cycles.
Battery types and power
Today, most floor scrubbers are designed and delivered with maintenance-free gel batteries. However, caution is advised, as there are also traditional lead-acid batteries that are cheaper to buy but require tedious daily maintenance.
It is also possible on some floor scrubbers to choose the power and therefore the battery life. You will then need to check the amperage in Ampere Hours (Ah). The voltage can be 12 or 24 volts.
Case of lithium Li-Ion batteries: These batteries are subject to specific storage and transport conditions.
Li-ion battery, one battery for multiple machines
The advantage of the new generation of Li-Ion batteries is their reduced size, allowing for compact and autonomous scrubber dryers like the Taski Swingo 150 or the Numatic 244NX.
The battery used in the Taski range is compatible with several devices, including the Taski Aero BP backpack vacuum cleaner , the Swingo 150, and the Taski Aero UP. A single battery model allows for compatibility with a wide range of equipment, simplifying fleet management.
Maintenance and recommendations on battery use.
Taski floor scrubbers are delivered without batteries and some without chargers. These options should therefore be purchased separately.
Nilfisk floor scrubbers are presented as a package with battery and on-board charger.
The entire current range of Numatic battery-powered scrubber dryers is equipped as standard with maintenance-free gel batteries in order to ensure the highest possible level of safety and convenience.
Quality batteries and a suitable charger are components that will determine the lifespan of your equipment.
But understanding the rules for using and storing batteries allows you to optimize and extend the performance of your machine.
Tips on using batteries
1 - Never leave your machine uncharged.
2 - Fully recharge the batteries after each use, regardless of the duration for which the machine is used.
3 - If the machine is not to be used for a period of 30 days or more , isolate the batteries by removing the fuses or disconnecting them.
4 - During prolonged storage, recharge the batteries every 3 months(*) and the day before putting the machine back into service.(*) The fuses will be put back in place during charging.
Special case of Li-Ion batteries
The storage of Li-Ion batteries requires special attention.
Li-Ion batteries must be stored in a protected, dry area, away from any direct heat source and out of direct sunlight.
It is best not to exceed 35°C. In any case, the storage temperature should never exceed 50°C.
Li-Ion batteries must be stored away from any accidental shock which could lead to fires with serious consequences.
