Tennant T391 Walk Behind Floor Scrubber

Upgrade to the Tennant T391 for Mid-Size Productivity With More Features, More Comfort, and More Cleaning Per Shift

When the T390's simplicity serves the job but you need ECO mode, a larger LCD display, and more ergonomic controls for operators running the machine across longer daily shifts, the Tennant T391 is the right step up.

This self-propelled battery-powered mid-size walk-behind scrubber delivers a 700mm dual disk cleaning path, dual 70L solution and recovery tanks, and up to 3.5 hours of run time — covering up to 2,147m² per hour in a machine designed for medium-sized retail stores, schools, hospitals, and commercial facilities where operator comfort and cleaning efficiency both matter. 

Key Features & Benefits of the Tennant T391

• 700mm dual disk cleaning path with dual 70L tanks for high productivity per shift — the wide dual disk cleaning path combined with equal 70L solution and recovery tanks means more floor covered per pass and more floor covered per tank fill, delivering significantly higher cleaning productivity than compact 500mm machines and fewer interruptions to the cleaning route across a full shift.

• ECO mode reduces noise and water consumption while extending run time to 3.5 hours — ECO mode lowers water usage and noise levels simultaneously while extending battery run time, making the T391 suitable for daytime cleaning in noise-sensitive environments and reducing the operating cost of each cleaning session compared to running in standard mode.

• Large LCD display with pre-programmed Standard and ECO cleaning settings — the clear LCD control panel displays machine status in multiple languages, alerts the operator when the solution tank is low or the recovery tank is full, and allows quick switching between Standard and ECO cleaning modes — reducing operator error and keeping cleaning routines consistent across different operators and shifts.

• No-tool, no-touch brush and squeegee change system for fast daily maintenance — the spin-on/spin-off brush and pad driver changes require no tools and no direct contact with worn consumables, while the no-tool squeegee attachment system makes post-cleaning routines fast and hygienic. The adjustable Linatex® squeegee blades deliver excellent water pickup to keep floors dry and safe after every pass.

• Water-resistant control panel and self-leveling brush for reliable daily performance — the water-resistant control panel protects electrical components from water ingress during cleaning, extending machine life in demanding environments, while the self-leveling brush automatically adjusts to maintain consistent contact across varying floor surfaces for a uniform clean every pass.

Why Choose the Tennant T391 Over Other Tennant Walk-Behind Models

The T391 sits alongside the T390 in the mid-range of the Tennant walk-behind lineup, sharing the same 700mm cleaning path but adding ECO mode, LCD display, a water-resistant control panel, and more ergonomic features — making it the right choice when the T390's simplicity isn't quite enough but the larger tanks and industrial capacity of the T500 and T600 are more than the job requires.

• More features than the T390 for operators running the machine across longer shifts — the T390 is a straightforward machine with basic indicator lights and no ECO mode. The T391 adds ECO mode, a large multi-language LCD display, a water-resistant control panel, and an optional integrated chemical dosing system — a meaningful upgrade for facilities where operators clean for extended periods and reducing fatigue, chemical use, and water consumption across the shift matters.

• Larger equal tanks than the T390 for fewer interruptions on bigger routes — the T391's dual 70L/70L tanks hold more than the T390's 65L/70L pairing, and significantly more than any compact model below it. For facilities with medium-to-large floor areas where the operator needs to cover as much ground as possible between tank refills, the T391's tank capacity is a practical advantage over the T390.

• The right mid-range choice before stepping up to the T500 or T600 — the T391 covers up to 2,147m² per hour with 70L tanks and up to 3.5 hours of run time — well suited to medium-sized facilities that clean daily. For facilities that need more than this — larger tanks, wider cleaning paths, or longer run times — the T500 (85L tanks, paths to 700mm) and T600 (121L tanks, paths to 900mm, up to 6.9 hours) are the natural next steps in the range.
