New Tennant T681 Rider Scrubber - 90AH Li-Ion Battery
Our Take (from the SES Sales Team)
“This T681 package is built for facilities that scrub in shorter runs: a store that cleans before opening, a school wing, a clinic floor. It uses a single 24 V, 90 Ah lithium-ion battery, and Tennant lists up to 1.75 hours of continuous scrubbing on it, so plan the route around that number. You still get everything that makes the T681 a good small rider. The 32 in dual disk deck is set up with a brush driver for texture and grout lines, the tanks hold 26.4 gal of solution and 29.1 gal of recovery, and Tennant rates the machine at 33,982 sq ft per hour of estimated coverage. Lithium-ion means no battery watering, and the onboard charger plugs in wherever the machine parks. One-button start lowers the scrub head and squeegee together, and the V-shaped squeegee runs Linatex blades. If one charge needs to cover a longer shift, the 180 Ah lithium-ion package doubles the listed runtime to 3.5 hours.”
