New Tennant T500 26" Disk Walk-Behind Scrubber with ec-H2O NanoClean - 225AH Battery
Our Take (from the SES Sales Team)
“The T500 26 in with ec-H2O NanoClean fits facilities that want to cut back on daily floor chemicals without giving up a mid-size machine: schools, healthcare buildings, offices and retail with tight layouts. ec-H2O electrically converts plain water into a cleaning solution, so crews handle less detergent, and the machine can still switch to conventional scrubbing when a floor needs it. Tennant also rates ec-H2O at higher coverage: about 23,124 sq ft per hour on the 26 in deck, against 20,571 conventionally. The 26 in dual-disk deck is the most maneuverable T500 and turns around in 59 in of aisle, while the 22.5 gal solution and 27 gal recovery tanks keep it on long routes. This package adds the Pro-Membrane control panel with Zone Settings, four 6 V, 225 Ah wet batteries with Smart-Fill automatic watering and an on-board charger. One caution: Tennant notes ec-H2O isn't suited to heavy concentrations of fats and oils, so greasy kitchen floors may still need conventional chemicals. For more open floors, the 28 in and 32 in ec-H2O packages cover more ground.”
A mid-size 26 in scrubber with ec-H2O NanoClean
The Tennant T500 is a battery-powered, self-propelled walk-behind floor scrubber for schools, healthcare, grocery, retail and other mid-size floors. Two 13 in disks clean a 26 in (650 mm) path, and the 22.5 gal (85 L) solution and 27 gal (102 L) recovery tanks keep it on long routes between dump-and-fill stops.
This package (T500-3001D) has the Pro-Membrane control panel, four 6 V, 225 Ah wet batteries with Smart-Fill automatic battery watering, ec-H2O NanoClean cleaning, a 25 A on-board charger and a set of pad drivers.

Questions
Tennant T500 26 in: common questions
Do the batteries need watering?
They are wet batteries, but this package includes Smart-Fill automatic battery watering, which fills them correctly from an on-board 0.66 gal tank. The operator only refills that tank.
Does it come with pad drivers or brushes?
One set of pad drivers comes standard. Polypropylene or nylon 26 in disk brushes can be chosen in place of the pad drivers when you order.
How much floor can it clean in an hour?
Tennant estimates about 23,124 sq ft per hour with ec-H2O and 20,571 conventionally, with a theoretical max of 28,600 sq ft per hour.
Will it fit my aisles and doorways?
The 26 in T500 is 58.5 in long, 27.5 in wide and 43.3 in high, the squeegee is 38.3 in wide, and it needs 59 in of aisle to turn around. Measure your tightest doorway and aisle before you order.
Can I still use detergent?
Yes. ec-H2O machines have two scrubbing modes, so the operator can switch to conventional scrubbing with detergent for heavier soil. Tennant notes ec-H2O isn’t suited to heavy concentrations of fats and oils.
