Powerkleen Floor Machines has been in the janitorial services and equipment business for over four decades. Our family-owned company has a wealth of knowledge when it comes to commercial and industrial floor scrubbers. Common questions we get from customers are listed here. If you have further questions, please don’t hesitate to reach out!
Industry-wide, frankly, not much of anything, but in our family-run shop, it’s different. We know what it costs to own and operate a business. We know how frustrating weeks of downtime can be. We know how expensive factory-authorized service is. We know money is hard-earned and value is hard-created.
We know when you pay more for refurbished, it’s because you rightfully expect a lasting result. WE DELIVER. In our shop, refurbished means we take only the cleanest, newest floor scrubbers that are in the best physical, electrical and mechanical shape, and we give them a full and complete processing for performance, durability and aesthetics.
We only sell a few models that we know very well, and we service every serviceable component on each of those units. Our service includes:
Grease all fittings
Verify & update all connections, cables & wire harnesses
Replace all wearable components, service drives & motors
Disassemble & test gearboxes, motor windings, commutators, carbon brushes, magnets
Replace worn actuators
Test all switches & buttons under load
Bench-test the battery charger Install new batteries
Change all the squeegees & hoses
Service the hydraulic & water feed solenoid systems
Inspect & service the wheels
Replace the seat
Change filters
Steam-clean the whole assembly
Remove & treat any corrosion
Touch-up & performance test
And much more!

Two of the reasons we focus on Tennant floor scrubbers, and these models in particular, is parts availability and ease of diagnostics. Anything on these machines that is user-serviceable can be done with no or minimal tools. Any necessary diagnostics can be done rapidly over the phone or with an in-person service call as needed with the onboard diagnostics and a simple voltmeter.
We offer a “reasonable warranty”. We ask that an operator or other capable person give several minutes on the phone with our technician to define the problem. Most of the time, it’s a very simple matter or adjustment. If we cannot reasonably diagnose and resolve the issue by phone, we will send a technician out and/or return the machine to our shop for rapid service.
If you are out of warranty, our technical phone support is free, and the parts are provided at cost with no markup. We get 10-75% off most parts and we always pass that savings on to you.
If you require more field support, reach out to us to see what we can do to help. We love our customers and will do all we can for the lifetime you own the equipment. However, please note that we do NOT pay or reimburse for rental floor scrubbers. We also do NOT pay or reimburse for technicians or repairs we have not arranged for. These costs are often astronomical and exaggerated, and are not part of our business plan nor our warranty. If you are in a mission-critical application, ask us about arranging a low-cost backup machine.
Our Terms & Conditions outline important information including:
* Order processing, shipping, and delivery
* Payments, financing, and deposit policy
* Warranty coverage and service support
* Limitation of liability

Maintenance and Efficiency:
– Lead-Acid batteries are an older technology that requires regular physical “watering” (adding distilled water to cells) and long, uninterrupted charging cycles.
– Lithium (LiFePO4) batteries are “set it and forget it.” They are lighter, charge faster, and require zero internal maintenance.
We believe your team should spend their time cleaning floors, not managing battery chemistry. We specialize in lithium because it offers the lowest Total Cost of Ownership. While the upfront cost is higher, the lifespan is 3–5 times longer than lead-acid, and you eliminate the labor costs (and safety risks) associated with battery watering and acid spills.
Yes. Lead-acid batteries lose water during the charging process. If you forget to refill them, the internal plates dry out and the battery fails prematurely. Lithium batteries are completely sealed and never require water.
• Lead-Acid: Usually requires 8–10 hours for a full charge. They also suffer from “memory effect,” meaning you shouldn’t stop a charge halfway through.
• Lithium: Can be fully charged in 2–3 hours. They also support opportunity charging—you can plug them in during a 30-minute lunch break to get extra run time without damaging the battery.
Lithium provides a consistent power output throughout the entire cycle. A lead-acid battery often loses “omph” (voltage drop) as it gets lower, causing the scrubber motors to run slower. Lithium stays at full power until the battery is nearly empty.
“If your cleaning crew is juggling multiple shifts, Lithium is the only way to go. You can charge the machine between tasks, effectively giving you a 24-hour cleaning window with a single machine.”
The T7 Standard is our primary recommendation for most facilities and comes in the traditional Tennant configuration. The T7 AMR manual version uses the same industrial T7 chassis and scrubbing system, but the autonomous robotics software has been professionally disabled so it operates as a standard ride-on scrubber.
We believe your team should spend their time cleaning floors, not managing battery chemistry. We specialize in lithium because it offers the lowest Total Cost of Ownership. While the upfront cost is higher, the lifespan is 3–5 times longer than lead-acid, and you eliminate the labor costs (and safety risks) associated with battery watering and acid spills.
We acquire these machines in large volume lots, which allows us to offer them as manual ride-on scrubbers once the autonomous system is disabled. This provides customers access to the proven T7 platform in a configuration that fits more operational requirements.
In most cases, autonomous functionality would require Tennant software activation, mapping, and service agreements through Tennant or an authorized AMR partner. If your facility plans to use robotics in the future, you may want to discuss that directly with Tennant.
This option works well for facilities that:
Prefer a traditional operator-controlled scrubber
Want the proven Tennant T7 platform
Do not need autonomous navigation features
Common environments include warehouses, manufacturing facilities, distribution centers, and large commercial buildings.
Yes. Each unit is professionally refurbished, tested, and inspected before delivery to ensure reliable operation in demanding commercial environments.
If you want the traditional Tennant configuration, the T7 Standard is our top recommendation.
If you prefer a streamlined manual configuration built on the same T7 platform, the T7 AMR manual version is an excellent alternative.
If you’re unsure which is right for your facility, our team can help guide you.
