The machine is the small cost.
The hours behind it are the big one.
If you are pricing a Tennant T1, a T7 or a Karcher walk-behind, you already know the floor needs scrubbing every night. The question is who runs the machine. A walk-behind or ride-on scrubber cleans only while a person drives it. A robot scrubber drives itself on a route you map once.
At the Utah median janitor wage of $15.48 an hour before benefits (Bureau of Labor Statistics, May 2025), 2 hours of scrubbing a night, 5 nights a week, is about $8,050 a year in wages for the floor alone. The robot still needs a person to fill it, empty it and start it, which takes minutes, not hours. That gap is what you are buying.

The CC1 Pro against the two Tennant machines people search for most and Karcher's current walk-behind. Where a manufacturer does not publish a figure, we say so rather than guess.

When each one
is the right buy.
Tennant T1: small, tight, occasional
A 15 inch micro scrubber for restrooms, small kitchens, break rooms and spill response. If the floor is small or the cleaning is not nightly, a T1 is cheaper and a robot is the wrong buy. We say so on site.
Tennant T7: huge floors with an operator on staff
A ride-on covers more floor per hour than any of these, with a 29 gallon tank. If you already pay an operator to ride the floor and the floor is very large, a ride-on makes sense. For big floors without the operator, look at our BG1 robot at 21,528 sq ft an hour.
See the BG1 →CC1 Pro: the same floor, every night, nobody driving
Schools, retail, offices, clinics and warehouse aisles cleaned on a schedule. It scrubs, sweeps, vacuums and dust mops in one pass, works the dirty spots with AI Spot Cleaning and hands the manager a cleaning report.
See the CC1 Pro →Already own a walk-behind? Keep it. Most sites run the robot on the long open floors and keep the walk-behind for edges, restrooms and spills.
Which one fits your building.
- ✓You clean the same floor every night. That is where the robot pays: the hours repeat, so the saving repeats.
- ✓Hiring and keeping night staff is hard. The robot shows up every night and does not need training twice.
- ✓Someone asks you to prove the floor was done. The CC1 Pro cleaning report shows what was cleaned and when, for the building manager or the client.
- ✓Your floor is under a few thousand square feet. Buy a T1 or similar. We would rather tell you now.
Buy it outright,
or spread the cost.
A CC1 Pro is $24,000 to buy, plus a one-time $1,000 setup fee, or 12 payments of $2,400 on the Robo Pro payment plan with no bank in the middle. Plan on the $2,899 self-cleaning dock. Leasing is a pilot program approved case by case.
RoboCare is required: $240 a month covers next business day on site response, quarterly maintenance, wear parts and firmware.
Installed and serviced
from Provo.
We survey the site, measure the floor, map the building, install the robot, train your staff and keep it running. Every visit is by our own technicians out of our Provo shop.
RoboCare, our service plan, covers next business day on site response, unlimited covered visits, quarterly preventive maintenance, wear parts, firmware and remote monitoring. A priority tier adds same-day and after-hours cover. We serve all of Utah and Las Vegas, and six states across the Intermountain West.
Where we place them,
and what else we place.
Questions we get asked.
How much does a Tennant T1 cost?
One US online listing on 18 October 2026 showed $5,394 for the corded T1 and $6,779 for the battery T1B. Tennant does not publish a list price. You also pay the operator for every hour it runs.
Is a robot scrubber worth it compared to a walk-behind?
When the same floor is cleaned most nights, usually yes, because the robot removes the hours of someone walking the machine. At $15.48 an hour, the Utah median janitor wage, 2 hours a night 5 nights a week is about $8,050 a year in wages before benefits. On a small floor cleaned now and then, a walk-behind is the better buy.
Can a robot replace a ride-on scrubber like the Tennant T7?
On very large open floors a ride-on covers more per hour, as long as someone drives it. For big floors without an operator, the Pudu BG1 robot covers up to 21,528 square feet an hour. We size it on a site survey.
Does the robot still need a person?
Yes, for minutes, not hours: filling clean water, emptying the dirty tank and starting the route. With the self-cleaning dock, even that drops.
Do you sell Tennant or Karcher machines?
No. We install and service Pudu and Keenon robots from Provo. This page compares them so you can choose with the published numbers in front of you.
