How the Tennant 8300 Machine Works

Wednesday, May 1, 2013

After receiving a few e-mails back and forth, a customer finally said, “I want to know physically how a sweeper/scrubber works. Can you describe it? I am operating a Tennant Model 8300 machine and don’t know how it works.” I answered, “Okay, I will give it a try.”

The Tennant Model 8300 is a small riding sweeper/scrubber. It is an electric/battery unit; however, the functionality in describing a sweeper/scrubber is the same. So, if we were discussing an American Lincoln 7760 or a Power Boss TSS80 the description would be the same as the model 8300 Tennant.

A sweeper/scrubber is naturally a combination of #1 a sweeper and #2 a scrubber. These are separate components on the machine which means you are able to “sweep only” or “scrub only” or “both.” The components of the sweeper section are:

  • Main and side brooms
  • Debris hopper
  •  Hopper dust filter.

The components of the scrubber section are:

  1. Scrub brushes (they may be disc brushes or cylindrical brushes).
  2. Solution (clean water) tank
  3. Rear and side Squeegees
  4. Liquid vacuum system
  5. Recovery (dirty water) tank

In a simple path moving forward, the side broom sweeps debris into the path of the main sweeping broom. The main sweeping broom sweeps debris into the hopper. The large debris, approximately the size of soda cans, settle into the bottom of the hopper. A vacuum system then sucks the lighter debris and dust through a hopper filter where it is then trapped. This concludes the sweeping part of the machine.

A combination of water and detergent flows from the solution tank to the scrub brushes. These brushes are generally located directly behind the main sweeping broom. With the liquid solution on the floor, the scrub brushes agitate on the floor surface loosening debris from the surface. As the machine is moving in a forward motion, the side and rear squeegee wipes the dirty solution and debris up off the floor. It is vacuumed up usually through the rear squeegee tube up into the recovery tank.

The advantage of operating and/or owning a sweeper/scrubber is that you have options. These machines can also perform one of the two functions as well. So if you just need to sweep you can. If you need to scrub only, you can do that as well.

For those owners of sweepers only or scrubbers only, what I have described is the same individual functions. These are simply combined to make the sweeper/scrubber.

As always I appreciate you reading my articles and, until next time you can contact me at

Thanks for reading.
