New Tennant T300 17" Disk Walk-Behind Scrubber
Our Take (from the SES Sales Team)
“The 17 in T300 is the one to look at when the space is tight but you still want Tennant's better-equipped walk-behind: restrooms, clinics, small retail, restaurants and classrooms crowded with desks. The body is only 20 in wide, so it slips between fixtures and through doorways, yet it carries the same 11 gal solution tank and 14 gal recovery tank as the 20 in model. What separates the T300 from the T300e is the work it takes off the operator. The Insta-Click magnetic head makes pad and brush changes quick, the stronger vacuum pulls 42 in of water lift, and Quiet-Mode drops it to 57.8 dBA, which makes daytime cleaning in occupied buildings realistic. This page is the build-to-order base machine, so you choose the batteries, pad assist or self-propel drive, and options like ec-H2O NanoClean when you order. For most routes, the wet 150 Ah batteries make sense; Tennant rates the pad assist model at up to 3.4 hours on them. If your floors are more open, the 20 in T300 covers more ground per pass.”
A 17 in T300 for tight, crowded floors
The Tennant T300 17 in disk is a battery-powered walk-behind floor scrubber for restrooms, clinics, classrooms, restaurants and small retail. A single 17 in (430 mm) disk scrubs while the 30 in squeegee dries, the 11 gal (42 L) solution and 14 gal (53 L) recovery tanks keep it working, and Tennant rates it at up to 17,000 sq ft per hour theoretical.
This listing is Tennant's T300 17 in disk base machine (T300-430-D), built to order. It has the Insta-Click magnetic pad and brush head, Quiet-Mode and a 13 A on-board charger. Batteries, drive type, the pad driver or brush, the control panel and options such as ec-H2O NanoClean are chosen when you order.

Questions
Tennant T300 17 in: common questions
Does this T300 come with batteries?
This listing is the build-to-order base machine, and batteries are chosen when you order: two 12 V wet 130 Ah or 150 Ah batteries, two sealed AGM 140 Ah batteries, or a single 90 Ah lithium-ion battery. Tennant recommends the wet 150 Ah batteries to get the most runtime from lead-acid.
What is the difference between the T300 and the T300e?
They share the 11 gal and 14 gal tanks and the 30 in squeegee. The T300 adds the Insta-Click magnetic head as standard, a stronger vacuum with 42 in of water lift (34.5 in on the T300e), Quiet-Mode and Supervisor QA Controls lock-out settings.
Should I choose pad assist or self-propel?
On pad assist, the rotating pad helps pull the machine forward while the operator guides it. Self-propel adds a 0.23 hp drive motor, and Tennant’s estimated coverage rises from 9,340 to 12,453 sq ft per hour, so it suits longer routes.
Will it fit my doorways and aisles?
The 17 in T300 is 51.25 in long, 20 in wide and 43.1 in high, and the squeegee is 30 in wide. Measure your tightest doorway and aisle before you order.
Can I add ec-H2O NanoClean?
Yes. ec-H2O NanoClean is a factory option that electrically converts water into a cleaning solution, and the machine can still scrub conventionally. Tennant notes it isn’t suited to heavy concentrations of fats and oils.
