Frequently Asked Questions
What is the difference between a cylindrical scrubber and a disc scrubber?
A cylindrical scrubber like the ULTIMAXX 1900 RB55 uses dual roller brushes that scrub while picking up light debris, reducing or eliminating the need for pre-sweeping. A disc scrubber focuses only on scrubbing and typically requires floors to be swept first.
Does the TASKI ULTIMAXX 1900 RB55 include a battery and charger?
Yes. All configurations include a battery system, charger, and dual cylindrical roller brushes.
How long does the battery last?
Runtime is typically 2 to 4 hours depending on battery configuration, floor conditions, and cleaning mode. IntelliScrub technology can help extend runtime by automatically adjusting brush pressure based on cleaning needs.
What types of facilities is this machine best for?
This scrubber is ideal for schools, warehouses, retail stores, healthcare facilities, and commercial buildings where debris pickup and deep cleaning are required.
Do I still need to sweep before using this machine?
In most cases, no. The cylindrical brush system allows the machine to scrub and pick up light debris in one pass. Heavy debris should still be removed beforehand.
Is this machine self-propelled?
Yes. The RB55 features a powered drive system, reducing operator fatigue and making it easier to clean larger areas.
What size area is this machine designed for?
The ULTIMAXX 1900 RB55 is best suited for medium to large commercial spaces, especially facilities with open floor areas and textured surfaces.
What is the solution tank size?
The machine features an 11.5-gallon (43 L) solution tank, allowing for longer cleaning cycles and improved productivity.
