Our Take (from the SES Sales Team)
"This 34" Disc floor scrubber is durable, powerful, and maneuverable. With the 25-gallon solution and recovery tanks, you can complete the assignment without needing to refill. The adjustable brush pressure up to 170 lbs. ensures that you can clean in the most severe environments. This machine is designed to be user-friendly. With its one-touch operation, paddle steering, and a 65" turning radius, it is easy to navigate through even the most congested areas. No matter the application, commercial or industrial, this is the scrubber for you."
A 34-inch disc walk-behind scrubber for large open floors
The Advance SC800™ 34D is a battery-powered, traction-drive walk-behind automatic floor scrubber with two 17-inch pad holders covering a 34-inch scrub path. Its 25-gallon solution and recovery tanks give up to 101 minutes of scrubbing per tank on low flow, which cuts down on dump and refill trips across big open areas. Scrub pressure runs at 80 lb for regular cleaning and 170 lb for extreme scrubbing, and the burst of power button adds more pressure, solution and detergent at a single touch. It is built for routine scrubbing of large hard-floor areas, and Advance offers it in a simplified ST version and a standard version with an onboard charger.
