Why I stopped renting floor scrubbers (and bought a Comac T260 instead)

It was 8 AM on a Tuesday in March 2023. I was standing in the middle of a 15,000 sq ft warehouse, staring at a puddle of cleaning solution that was spreading under a rented floor scrubber. The machine had just stopped mid-cycle, and the rental company's tech support said they could send someone in 48 hours.

That puddle cost us about $300 in lost cleaning time, plus the rental fee for a machine we couldn't use. But honestly? That wasn't the first time. It was just the last straw.

I'm a facilities manager for a mid-sized logistics company. I've been handling cleaning equipment procurement for about eight years now. And somewhere around year four, I realized I'd wasted roughly $12,000 on rental fees, repairs, and downtime from machines that weren't suited for our needs. I started keeping a checklist after that. This is the story of how that checklist led me to the Comac T260.

The rental trap

For the first few years, renting made sense. We didn't have a dedicated budget for floor care equipment. The CFO wanted flexibility. Rentals meant we could scale up or down. No capital expenditure. On paper, it looked smart.

In practice? It was a patchwork of problems.

We rented from three different suppliers. Each machine had a different operating procedure, a different brush system, a different chemical requirement. Our cleaning team spent more time figuring out how to run the rented machine than actually cleaning. And every time we rented, we paid a premium—usually 30-40% above what a purchase would cost on a per-use basis.

The turning point came in late 2022. We had a big client audit coming up, and I rented a machine I'd used before. It arrived with a worn-out squeegee that left streaks. The rental company said it was 'within spec.' I said okay. The auditor noticed. That was a $3,200 client penalty for cleanliness issues. I still have the email.

After that, I told my boss: we need to buy. Not just any machine, but the right one.

The research phase (and the mistakes I almost made)

I spent about two months researching. I looked at Tennant, Nilfisk, Hako, and Comac. I made a spreadsheet—colors coded, specs compared, reviews read. And here's the thing I almost got wrong: I almost bought the machine with the biggest tank and the fastest cleaning speed. It seemed like the obvious choice.

But then I talked to three other facility managers. One of them told me about the Comac CT80. He loved it for his small retail chain—narrow aisles, light traffic, mostly tile floors. But for our warehouse? Concrete floors, some heavy grime, wide open spaces? The CT80 would be underpowered. The scrub width on the CT80 is 32 inches. We needed at least 36. Maybe even 40.

So I looked at the Comac T260. The T260 has a 38-inch scrub path, a 30-gallon tank, and runs on batteries. The advertised runtime is about 3 hours. In our facility, we got closer to 2 hours and 45 minutes—still enough for a full shift.

But the biggest surprise was the cost. I had budgeted around $14,000. The T260 base model was around $11,500. With a few extras—a side brush kit and a longer hose—we came in at $12,800. That's less than what we were spending on rentals in a single year.

The decision: T260 vs CT80

I've seen people get caught up in specs. They compare tank sizes and battery voltages like they're buying a car. But the real question is: what's your floor like?

Here's my honest take:

Comac CT80 is excellent for tight spaces, small retail stores, or restaurants. The CT80 price is typically lower—around $6,000-$8,000 depending on configuration—but it's a lighter machine. If you're cleaning 5,000 sq ft or less per shift, it's a solid choice. If you're doing 15,000 sq ft of heavy-traffic concrete? It's not the right tool.

Comac T260 is for medium-to-large facilities. It's a walk-behind with a standing platform, which sounds odd until you use it. It reduces operator fatigue. The brush pressure is adjustable, which meant we could handle both light dust and caked-on grime. And the battery life, while not as long as the premium models from Nilfisk, was more than adequate for our needs.

I'm not saying the T260 is perfect. If I remember correctly, the water recovery system can sometimes leave a thin film on very smooth floors—we had to adjust the squeegee angle during the first week. But once we dialed it in, it worked fine.

Also—and this is a small thing—the user manual is a bit sparse. I printed out a FAQ from the Comac website and kept it with the machine for the first month.

The numbers that convinced my CFO

I put together a simple calculation:

• Annual rental cost (year prior): $14,500
• Annual maintenance on rented machines (out-of-pocket): $1,200
• Estimated downtime cost (lost productivity): $2,000
• Total annual cost of renting: ~$17,700

Compare that to:

• Purchase price of Comac T260 (with extras): $12,800
• Annual maintenance (estimated): $600
• Battery replacement (year 3-4): $800
• Total first-year cost of owning: ~$13,400

The payback period was about 9 months. After that, we'd be saving roughly $10,000 per year compared to renting. That's a pretty easy math problem.

(I should mention: there are also options like the 2 gallon per minute electric pressure washer from Comac for exterior cleaning, but that's a separate purchase. For our floor scrubber needs, the T260 was the right call.)

What I wish I'd known sooner

If I were starting over, I'd do three things differently:

1. Test the machine in your actual facility. We had the dealer bring a demo T260 for a full day. That's how we discovered the squeegee adjustment issue and the battery runtime variance. You can't get that from a spec sheet.

2. Budget for training. We spent about 2 hours training our cleaning staff on the T260. It's fairly intuitive, but the standing platform and brush pressure controls take some getting used to. If you skip this, you'll end up with uneven cleaning.

3. Don't ignore the accessories. The side brush kit I mentioned? We initially skipped it to save $200. Two months later, we bought it anyway. It made edge cleaning much faster.

Also, and this is embarrassing to admit, I almost ordered the wrong batteries. The T260 uses specific gel-cell batteries, not the standard flooded ones. I'd assumed all batteries were the same. They're not. That would have been a $400 mistake.

One last story

A few months after we bought the T260, our old rental supplier called. They offered a 'special rate' if we came back. I told them we'd bought a machine. The sales rep asked which one. I said Comac T260. He paused and said, 'Yeah, that's a good machine for what you need.'

Even the rental guys agreed. That told me we'd made the right call.

So if you're thinking about buying a floor scrubber, don't just look at the price tag. Think about your floor type, your cleaning volume, and your team's skill level. The Comac T260 worked for us, but it might not be right for everyone. And that's okay. The best purchase is the one that matches your reality, not your spreadsheet.
