• 20 Metre Commercial Hose: Heavy-duty, wire-braided and dual-layered for extra durability around machinery and job sites.
• Five Quick-Connect Pro Nozzles: From a precise pinpoint jet to a broad spray—tackle grime, mud, and even algae build-up across vast areas.
• 13-Inch Flat-Free Tyres: Move over gravel, grass, or uneven surfaces with stability and ease, thanks to the robust tubular frame and real-world wheel design.

What’s It Like in Day-to-Day Use?

The TX870 shines brightest on jobs where ordinary washers give up. Contractors note its rapid cleaning on mining vehicles, tractors and stained concrete, while rural users appreciate the reach of the 20m hose and the reliability of the AR pump, even after hours on the job. Rugged brass connectors and a specially engineered chemical siphon enhance durability and flexibility, providing a real-world advantage on mixed-duty tasks.

Transport around-site is straightforward with its upright stance and big wheels—no awkward lugging or constant repositioning—and if you need a measured approach for more delicate areas, the variable pump and nozzle selection mean you’re prepared for both power and precision, whenever you need it.

Set-Up and Care Notes

• Initial setup requires fresh petrol and oil—run through safety checklists before first use.
• Choose an open, well-ventilated area for startup to ensure best performance and longevity.
• Familiarise with the safety lock, trigger operation, and low-oil feature—important for trouble-free ownership.
• Maintenance is hands-on but straightforward: keep an eye on hoses, connectors, and change engine oil as per manual guidance.
• If integrating with pre-existing spray lances or extended accessories, double check size and fitment details on Edisons for a smooth connection.
