Tennant T7 AMR

[cam2s]

One of the accounts I service for work has one of these Tennant Floor scrubbers. I call it the “giant store Roomba.” For those unfamiliar it is a ride on floor scrubber than has an Automatic robotic mode. I was curious as to how the machine was programmed so I looked it up. You do have to teach it routes, though it can react to obstacles and stuff like a home Roomba can. I was a bit taken aback by the fact that it cost as much as a new Mercedes-Benz E class. I know it’s suppose to save labor but I think it would take quite a long time to recoup that much upfront capital cost on it. Has anyone ever seen or used one of these?

All industrial equipment can cost as much as the company wants to charge for it, because they know the business has zero choice in the matter. They either buy it or don't.

They depreciate like a rock and you can often get these at industrial auctions for $200 +/-.

I have seen a lot of the command nodes stuck to the walls in stores, but never actually seen one in use.

I'd

Do a hard pass unless your contracts are for 100 thousand square foot areas and up. It's like something an airport would use.
I was manager at Walgreens and had to stay while floor crews came. There's no way it's an investment that will help your business maybe bankrupt but not make you money.

Looks like some future "riding" automated mower.Like the strap that discourages someone from climbing aboard while the scrubber works.Wish in the videos they would CAN the CRAPPY music and have a narrator tell about the machine and how it works.Does it go to its charger station automatically like a Roomba can?

Based on reading the instruction manual, the only automated part is it can be programmed to drive a pre-planned route and not require paying an employee. This has to be manually programmed by placing lidar codes all over the store for it to read and follow, or manually driven to set up a route and then put into automated mode to follow that path.

It still has to be mounted and driven to the charger when its battery is low. It can take up to 12 hours to charge the batteries. You also have to top off the batteries with distilled water as needed, as the water level gets consumed by charging.

My high school had one of these machines a decade ago; the custodians used it in the large "commons" space to scrub the floor after all 3 lunch periods were over. Sadly, I never got to use this myself, but I always found it fascinating to watch whenever I was walking to and from classes.
