Comac CT5 vs T291 Floor Scrubbers: What I Learned After $30K in Mistakes

If you're trying to choose between the Comac CT5 and T291 floor scrubbers, the short answer is this: for most medium-to-large facilities, the CT5 is the better buy. The T291 only wins when narrow aisles, elevator access, or storage space are the deciding factors. And before you order either one, download the global industrial floor scrubber manual 641244 and check the part numbers against the actual machine. I learned that the hard way.

Yes, I know the name Comac also appears on an airplane. If you Googled 'comac c919 first commercial flight,' you're looking for the Chinese aircraft manufacturer—not the Italian floor scrubber company. This article is about the cleaning equipment Comac, and the advice below is still worth reading if you're responsible for floors.

Why my opinion isn't just an opinion

I've been handling floor scrubber orders for nine years. In that time, I've personally made and documented 14 significant mistakes, totaling roughly $30,000 in wasted budget. I now maintain our team's equipment checklist so other people don't repeat them. The biggest lesson from those mistakes? Never trust the marketing name. Trust the manual.

CT5 vs T291: what I actually think

Here's the thing: the CT5 and T291 are both solid machines, but they solve different problems. The CT5 is a compact ride-on scrubber built for large, open areas—warehouses, production halls, big retail floors. The T291 is a more compact unit for tight spaces, mixed aisles, and sites where the machine has to share space with pallet racks or loading docks.

If most of your facility is open, a CT5 floor scrubber will clean more square footage per hour and put less strain on the operator. The T291 floor scrubber makes sense when aisle width is under four feet or when storage space is laughably small. In other words: choose the machine based on your building's floor plan, not the maximum capacity on the spec sheet.

The manual 641244 mistake

The global industrial floor scrubber manual 641244 is a bulky document, but it's the one you need. It covers the CT5 and T291 global versions, and it includes the parts diagrams, pad driver sizes, and service intervals. It also tells you exactly which squeegee assemblies are compatible. That last part is where I failed.

A few years ago, I ordered 12 CT5 floor scrubbers for a client's warehouse. The quote said 'with pad holder.' The sales rep confirmed 'with pad holder.' What neither of us checked was the pad driver diameter. The machines arrived with 20-inch drivers, but the client had standardized on 17-inch pads across their other sites. In the manual 641244, the 17-inch driver is listed as a separate part number. I didn't open the manual. The client didn't open the manual. The result: $5,700 in replacement drivers, $600 in freight to return the wrong parts, and a client who started questioning my competence.

The 'budget freight quote' saved us $150. The correction cost $6,300. That's not budget—that's expensive math.

I still kick myself for that one. If I'd spent 30 minutes with the manual before signing the PO, the order would have been right the first time. Instead, I learned a rule: the part number goes on the purchase order. No part number, no PO.

The most frustrating part of this business is how easily the same mistake repeats. You'd think a written purchase order would be enough, but until a part number is in the manual and on the serial plate, it's just a suggestion.

Check the Comac logo before you accept delivery

Here's another thing I now check: the Comac logo on the motor plate. A decal on the front of the machine is easy to fake. The stamped or laser-etched logo on the motor plate is much harder to replicate. If the logo looks even slightly off, or the model number doesn't match the manual, don't sign the delivery receipt.

That advice came from a 2022 counterfeit parts scare. A 'dealer' was selling imported machines with a similar-looking logo, and customers were only catching it after the first service call. The genuine parts aren't that hard to identify once you know where to look. But most buyers never look past the front badge.

What changed in floor scrubber buying

Between 2020 and 2025, the way you buy these machines changed a lot. Five years ago, the best practice was to call your local distributor, take their word, and write a PO. Now you can search for the global industrial floor scrubber manual 641244 online, compare part numbers, and check the actual Comac logo against official product photos before you pay.

The fundamentals haven't changed. You still need to verify before you commit. But the execution has transformed. In 2020, 'trust your dealer' was normal advice. In 2025, it's a good way to end up with the wrong pad drivers and a late project.

The checklist I use now

Every order in our team goes through the same pre-check before money moves:

• Photo of the serial plate and the stamped Comac logo.
• Cross-check the model and part numbers against manual 641244.
• Pad driver and squeegee sizes written directly on the PO.
• Delivery date written as a calendar date, not 'in about two weeks.'

That's it. Five minutes of checking before the order saves weeks of fixing after it.

When this advice doesn't apply

Now the boundary conditions. If your facility is under 5,000 square feet, the CT5 is probably overkill. A T291 or even a standard walk-behind unit might be enough. This checklist also assumes you have access to Comac parts and service in your region. If there's no dealer nearby, the simpler machine is often the safer choice.

And if you're here for the 'comac c919 first commercial flight' story, stop. The airplane Comac and the floor scrubber Comac are different companies. My checklist won't help you board a flight. But if you're responsible for a commercial floor, start with the manual—and don't make my mistake.
