The TASKI ULTIMAXX 1900 SD50 Gel MBU Kit, catalog number D1232821, combines a versatile 50 cm single-disc cleaning deck with a maintenance-free gel battery configuration and the modular flexibility of the ULTIMAXX 1900 platform.

Its 43-liter solution tank and 45-liter recovery tank provide useful capacity for commercial cleaning routes while the 20-inch deck remains maneuverable enough for corridors, retail areas, schools, healthcare facilities, and other environments with frequent turns or obstacles.

20-Inch Single-Disc Cleaning Deck

The SD50 configuration uses a 50 cm / approximately 20-inch single-disc deck.

This wider single-disc option provides more floor coverage per pass than the 43 cm SD43 configuration while retaining the maneuverability of a compact walk-behind scrubber.

The single-disc system is well suited for:

• Routine hard-floor scrubbing

• Daily maintenance cleaning

• Corridors and open areas

• Retail spaces

• Schools

• Healthcare facilities

• Office and hospitality environments

Gel Battery System

This configuration uses maintenance-free gel batteries.

Gel batteries are sealed and do not require routine watering, helping simplify battery maintenance compared with conventional flooded lead-acid systems.

43-Liter Solution Tank

The ULTIMAXX 1900 provides a 43-liter solution tank.

This gives operators practical cleaning capacity without requiring the footprint of a much larger walk-behind scrubber.

45-Liter Recovery Tank

A 45-liter recovery tank provides slightly greater capacity than the solution tank, supporting practical one-pass scrubbing and solution recovery.

TASKI Whisper Technology

ULTIMAXX incorporates TASKI Whisper vacuum technology.

The system is designed to provide effective dirty-water recovery while supporting quieter operation in occupied facilities and daytime cleaning programs.

IntelliTouch, IntelliKey and IntelliZone

Depending on installed options, the ULTIMAXX platform can support:

• IntelliTouch – Touchscreen operator interface and user guidance

• IntelliKey – Configurable machine access and controls

• IntelliZone – Stored cleaning parameters for repeatable cleaning programs

These capabilities should be considered platform-compatible unless specifically confirmed as included with D1232821.

IntelliTrail 2.0 and IntelliPredict

ULTIMAXX supports TASKI’s connected digital ecosystem.

Depending on configuration:

• IntelliTrail 2.0 can provide fleet-management and machine-use information.

• IntelliPredict can support proactive maintenance planning and equipment monitoring.

IntelliFlow and IntelliDose Compatibility

The ULTIMAXX platform can support IntelliFlow controlled water distribution and IntelliDose / IntelliDose+ chemical dosing on appropriately equipped configurations.

These technologies are designed to improve solution and chemical consistency while reducing unnecessary consumption.

IntelliScrub and EBU Compatibility

On compatible configurations, IntelliScrub allows mechanical cleaning pressure to be adjusted to suit floor conditions.

The optional EBU electronic brush-lifting system can reduce manual handling of brushes and pad drivers.

Optional HEPA H13 Filtration

The ULTIMAXX platform can be equipped with optional HEPA H13 filtration.

This system is designed to capture very fine particulates from the vacuum exhaust stream and may be useful where enhanced exhaust filtration is desired.
