TT1840G Twintec Numatic Scrubber Dryer
The Numatic TT1840G is a compact mains-powered scrubber dryer for suitable commercial hard floors. Its 400mm brush width and 18-litre water capacity suit areas where furniture, counters or narrow access routes can make larger equipment awkward.
The machine combines scrubbing and liquid recovery for a planned cleaning route. Facilities staff can use its compact format for routine maintenance in shops, offices, cafeterias and other shared premises.
Compact Brush and Vacuum Systems
A 400W brush motor works with a vacuum motor rated at 300W maximum power. The brush rotates at 150rpm to scrub the floor while the recovery tool collects loosened soil and used cleaning solution.
The machine supports a 400mm brush or a compatible 360mm pad arrangement with the correct drive board. These separate dimensions help identify the appropriate working attachment for the model and floor-care task.
Mains Reach and Accessible Routine Care
The 20m cable provides working reach from a suitable power socket. An adjustable handle supports the operator’s working position, and its folding arrangement helps with storage and transport between jobs.
Colour-coded controls and access for brush or pad changes support everyday preparation and maintenance. The compact tank arrangement is practical for teams moving between commercial areas with restricted access.
Compare the TT1840G with other Numatic floor care machines when matching equipment to your premises, and choose compatible floor cleaning chemicals for the task. Trained operators should follow the supplied manual for setup, recovery-system care and safe isolation before maintenance.

- Routine scrubbing and dirty-water recovery.
- Facilities with suitable mains supplies and compact storage needs.
Directions for Use
- Prepare the floor and inspect the machine: Read and understand the operator manual before use. Sweep or dust-mop loose debris from the floor and place suitable warning signs around the working area. Check the cable, plug, brush, floor tool and hoses for damage, and plan a route that keeps the mains lead away from the cleaning action and passing traffic.
- Fit the cleaning accessory and fill the tank: Isolate the machine from the power supply before fitting or changing a brush, pad or floor tool. Choose a compatible accessory for the floor finish and follow Numatic's fitting procedure. Fill the clean-water tank to a maximum of 18 litres, including detergent, using a non-foaming chemical recommended for automatic scrubber dryers at its stated dilution.
- Scrub and recover the dirty solution: Adjust the handle for a comfortable working position, set the water flow and operate the brush and vacuum controls as described in the manual. Move methodically over the prepared floor while managing the cable. Check water pickup as you work and stop to inspect the recovery system if water is being left behind.
- Empty, clean and store after use: Switch off and unplug before cleaning or maintenance. Empty and rinse the waste-water tank after each use, and keep the brush, pad, floor-tool blades and filters clean. Inspect components for wear and replace damaged parts as required. Follow the manual's routine-care schedule, store the machine safely and do not steam-clean or pressure-wash it.
FAQs
Is the TT1840G powered by mains or battery?
This is the mains-powered TT1840G, designed for a suitable 220–240V, 50Hz supply. It uses a power cable during cleaning, so the working route and cable management should be planned before starting.
What size of floor area is it designed for?
Its compact layout is useful in smaller or congested commercial areas such as shops, offices and cafeterias. Consider the available turning space, power access, floor type and cleaning workload when selecting a machine; actual coverage depends on site conditions and the cleaning method.
How much water does the tank hold?
The stated water capacity is 18 litres. Numatic's filling instructions set an 18-litre maximum including any cleaning chemical. Use the fill indicator and keep dirt and debris out of the clean-water tank.
Can the machine use pads as well as a brush?
Yes. The TT1840G supports a 400mm brush or a compatible 360mm pad arrangement with the correct drive board. Choose accessories suited to both the machine and the floor, and disconnect the power before changing them.
What cleaning solution should I use?
Use a non-foaming detergent recommended for automatic scrubber dryers and suitable for the floor finish. Follow the chemical manufacturer's dilution and handling instructions. A detergent intended only for manual cleaning may be unsuitable for the machine's recovery system.
What routine care does the TT1840G need?
Empty and rinse the waste-water tank after use and keep the brush, floor-tool blades, hoses and filters clean. Check for wear or damage and follow Numatic's maintenance schedule. Always switch off and unplug before carrying out cleaning, maintenance or accessory changes.
