New Tennant B7 24" Walk-Behind Battery Burnisher
Our Take (from the SES Sales Team)
“The B7 is the step up from a 20 in walk-behind when you have more floor to cover but don't need a rider. This 24 in version is rated at up to 24,000 sq ft per hour, and it is self-propelled, so the operator steers instead of pushing a heavy machine. The pad runs at 1,875 rpm, and Tennant says the battery power and pad speed deliver propane-like gloss without the fumes or tank storage. Active dust control with HEPA filtration at 99.97 percent at 0.3 micron comes standard, which helps keep burnishing dust out of the air in schools, hospitals and stores. It is quiet at 63 dBA. For pad changes, the head flips up and locks at 90 degrees, and it tilts and locks at 45 degrees for moving between areas. At 30 in wide, the 24 in model is the better fit for tighter corridors and elevators than the 27 in.”
A self-propelled 24 in battery burnisher with active HEPA dust control
The Tennant B7 is a battery-powered walk-behind burnisher for retail stores, schools, healthcare facilities and office buildings. A 24 in pad spinning at 1,875 rpm brings floors to a high-gloss finish, and the self-propelled drive does the pushing for the operator.
This is Tennant's B7 24 in base build: self-propelled transaxle drive, automated variable down pressure, active dust control with HEPA filtration and a 25 A on-board charger with a 15 ft (3 m) power cord. Tennant ships it with one burnishing pad, a paper filter bag, a HEPA filter and the operator manual.
Condition: New.

Questions
Tennant B7: common questions
Is the B7 safe to run in occupied buildings?
It is a battery burnisher, so there are no propane fumes or tanks to store. Tennant rates it at 63 dBA with active HEPA dust control.
How long does it run on a charge?
Tennant lists up to 3 hours. Runtime depends on the battery pack, down pressure and the pad used, so ask us which pack is on this unit.
How are pads changed?
The head flips up and locks at 90 degrees, so the operator can center and change the pad from a comfortable standing position.
Will it fit in elevators and tight halls?
This 24 in B7 is 30 in wide with a 62.5 in minimum aisle turn. Measure your elevators and tightest doorways before you order.
What does automated down pressure do?
The operator sets pad pressure from the controls and can change it while burnishing, instead of adjusting it mechanically.
Not sure the B7 fits your floors?
Tell our team about the floor, the building and the shift, and we will help you decide if this is the right machine.
