Tennant T390 Walk Behind Floor Scrubber

The Tennant T390 Delivers Dual Disk Productivity in a Mid-Size Machine

When the compact 500mm single-disk models aren't covering enough ground and you need a proper step up in cleaning path width and tank capacity without moving to a large industrial machine, the Tennant T390 delivers.

This self-propelled battery-powered walk-behind scrubber combines a 700mm dual disk cleaning path with a 65L solution tank, 70L recovery tank, and steel scrub deck with roller guide wheels — covering up to 2,503m² per hour in a machine that's still compact and manoeuvrable enough for schools, hospitals, retail stores, and medium-sized commercial facilities. Overall, the T390 is a straightforward, reliable machine built to get the cleaning done quickly without unnecessary complexity.

Key Features & Benefits of the Tennant T390

• 700mm dual disk cleaning path for significantly higher productivity than compact models — the dual disk 700mm cleaning path covers 40% more floor per pass than a 500mm single disk machine like the T291 or T290, delivering noticeably faster cleaning across medium to large facilities and reducing the total time operators spend scrubbing the same area each shift.

• 65L solution and 70L recovery tanks for fewer stop/refill cycles — the large tank pairing means operators can cover significantly more floor before stopping to empty and refill, reducing cleaning interruptions and keeping productivity high across larger floor areas that would require multiple tank cycles on a smaller compact machine.

• Steel scrub deck with roller guide wheels protects the facility and the machine — the tough steel scrub deck withstands the rigours of sustained daily commercial use, while roller guide wheels protect walls, racking, and fixtures from accidental contact during cleaning — an important practical feature in congested environments like retail stores, school corridors, and healthcare facilities.

• No-tool brush and squeegee blade replacement for fast, simple maintenance — brushes and squeegee blades change out without tools, keeping daily maintenance quick and accessible for any operator. The four-sided Linatex® squeegee blades can be rotated before replacement, extending blade life and reducing ongoing consumable costs.

• Tilt-back recovery tank for easy access to internal components — the recovery tank tilts back to give clear, unobstructed access to batteries and internal components for maintenance and servicing, reducing the time and effort involved in routine upkeep and making it easier for technicians to service the machine on site.

Why Choose the Tennant T390 Over Other Tennant Walk-Behind Models

The T390 sits above the T291 and T290 in the Tennant walk-behind range — a meaningful step up in cleaning path width and tank capacity for facilities that need more productivity per shift without the additional features, complexity, or price of the T391, T300, T500, or T600.

• The cleaning area has grown beyond what a 500mm compact machine can handle efficiently — the T291 and T290 cover up to 1,436–1,822m² per hour with a 500mm path. The T390's 700mm dual disk path covers up to 2,503m² per hour — a 38–75% productivity increase that makes a real difference in facilities where scrubbing large open floor areas like retail floors, school halls, or hospital corridors takes longer than it should with a compact machine.

• You need more tank capacity but not the advanced features of the T391 or T300 — the T390's 65L/70L tanks hold significantly more than the T291's 50L/50L setup, reducing refill frequency on larger routes. Unlike the T391, the T390 doesn't add an LCD display, ECO mode, or additional technology settings — keeping the machine straightforward and simple to operate while delivering the tank capacity and cleaning path upgrade the job requires.

• Robust construction is a priority but advanced technology isn't required — the T390's steel scrub deck and roller guide wheels deliver a level of construction robustness suited to demanding daily commercial use in schools, hospitals, and retail environments. For facilities where the floor area and soil load justify a wider machine but Quiet-Mode™, ec-H2O NanoClean®, or multiple scrub head options aren't required, the T390 delivers the right productivity at the right price point.
