Do I need to use detergent with the machine?


Detergent is recommend to give the most effective cleaning performance for operator, machine and environment. We have a wide selection of detergent available dependant on the task in hand which can be viewed in the detergents section, or alternatively if you contact us we will be able to advise on more specific applications.

Do I need a disk or a roller machine?


A scrubber dryer with a roller brush head is especially suitable for extensive deep cleaning of structured and heavily soiled floors thanks to its high brush speeds and a higher contact pressure per cm². This brush head technology also offers substantial advantages when dealing with coarse dirt as the contra-rotating rollers absorb the particles, which are then fed back to the coarse dirt container. This means that pre-sweeping as a previous work step is no longer needed. Scrubber dryers with disc brush heads are generally used for maintenance cleaning and light soiling. These floor cleaning machines are especially popular for smooth floors and noise-sensitive areas, such as in hospitals or the hotel and gastronomy sector.

What happens when I am finished with the machine?


It is your responsibility to off hire the equipment when you no longer need it. To avoid aborted journey’s we do not accept auto off hires and you must contact the hire team to obtain an off-hire reference. An off-hire reference will be provided to confirm the off hire and a collection date will be scheduled. To off hire please contact us.
