Kärcher B 90 R Compact Ride-On Scrubber Dryer

Consumables And Accessories


The Kärcher B 90 R is compact yet efficient with 90 degree steering which allows flexible on the spot turning. Easy to use, with a 90 litre water tank.  Available in both disc and roller, this machine is ideal for tight spaces within a large area.

Extremely easy to manoeuvre

Thanks to its very short and narrow construction, the B 90 R is very agile and easy to manoeuvre despite large water tanks. The 90° steering system allows you to turn on the spot and a low centre of gravity ensures excellent traction.

Long operating times

The generous battery compartment allows for large capacity batteries to be fitted. With maintenance-free or low-maintenance batteries in the pack variants. The speed of the vacuum and brush motors can be controlled to save energy and ensure even longer run times.

Simple operation

All machine operations are controlled with the single, EASY switch. Additionally, the brush heads are easy to charge meaning one machine can be used for multiple applications.

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.
