Comac Floor Sweeper or Floor Scrubber? A Quality Inspector's Guide (and a Quick C919 Clarification)

Let me clear up a name collision before we get to the actual equipment. COMAC is the Commercial Aircraft Corporation of China. Comac is an Italian commercial cleaning equipment manufacturer. One makes the C919 narrow-body jet. The other makes floor sweepers, scrubber dryers, and industrial dust collectors. They are not the same company, but the search engines don't know that.

I'm a quality/compliance manager for a distributor of commercial cleaning equipment. I review 200+ machines and parts orders a year, and in Q1 2024 I rejected 6% of first deliveries because of mislabeled components. I've also been the small-business customer who got ignored because I only wanted one motor. That's why I'm writing this the way I'd explain it to a friend: no fluff, no universal answer, just a way to figure out which problem you're actually solving.

When I was starting out, the vendors who treated my $200 orders seriously are the ones I still use for $20,000 orders. Small doesn't mean unimportant; it means potential.

There's no one 'right' Comac machine

A floor sweeper is not automatically better than a floor scrubber. It depends on what you're cleaning and why. Here's the shortcut I use when I'm on-site:

• If the floor is dry and the problem is debris, dust, or litter → you're looking for a floor sweeper.
• If the floor is hard, smooth, and needs to be visually clean without wet residue → you're looking for a floor scrubber.
• If you already have a machine and it's underperforming → you're looking for parts, not a new purchase.

That third one is the one I see most often. I've seen a $28,000 scrubber sit idle for three weeks because someone ordered the wrong brush motor from a generic supplier. It wasn't the machine's fault.

Situation 1: Searching for a floor sweeper in Ogden

If you searched for "floor sweeper Ogden," you're likely managing a warehouse, garage, workshop, or material handling area where dry debris is the enemy. In this situation, a sweeper is usually the right call because it leaves the floor dry and safe for the next lift truck.

What to check before you buy:

• Dust filtration: you don't want to sweep dust into the air. Ask for the filter class, not just a "HEPA-like" sticker.
• Brush access: if changing the side broom takes 15 minutes instead of 2, you'll start skipping it. I've seen that happen. (Note to self: always time the broom change during demos.)
• Hopper size vs. your route length. If you're stopping to empty every 15 minutes, you've bought the wrong machine.

I know I should have checked the dust filter seal on a demo sweeper before we bought it, but I thought "what are the odds?" The odds caught up with us at 10 a.m. Dust blew straight out the back seam and settled on the freshly waxed floor. We fixed it with a $30 gasket, but the embarrassment stuck.

Situation 2: Floor scrubber motor specs matter more than the sticker

If you're looking at a floor scrubber, "floor scrubber motor" is not one spec—and you're gonna want to know which motor matters for your symptom. A typical walk-behind scrubber has at least three motors: the brush motor, the vacuum motor, and the traction motor. Each has a different job, and each can fail in a way that gets misdiagnosed.

Here's what I check:

• Duty rating. A motor rated for continuous duty should run a full shift without thermal cutoff. A lot of budget machines quote the same amps but not the duty cycle.
• IP rating. In a wet scrubber, the brush motor is in the splash zone. If it's not rated for moisture resistance, you're buying a recurring repair.
• Brush speed, not just horsepower. Two motors with the same kW can have very different pad speeds, which changes the finish on polished concrete.

In that same audit, the most common failure wasn't mechanical—it was documentation. The motors said "24V," but the controller expected 24V at 30 amps, and the replacement was rated at 18 amps. It worked for five minutes. Then it didn't.

Dodged a bullet when I double-checked the amp draw on a used ride-on scrubber before approving the purchase. The seller said it was a 24V system. It was actually 36V, which would have meant swapping every battery and the charger. I was one click from a very expensive mistake.

Situation 3: Industrial floor scrubber parts Wisconsin buyers should check

If you're searching "industrial floor scrubber parts Wisconsin," your machine is probably down right now. I get it. You don't want a long essay on maintenance philosophy. You want to know whether to fix it or scrap it.

My rule of thumb: if the repair cost is under 50% of the machine's current value and the frame, tank, and main electrical harness are still solid, repair it. If the replacement cost is $30,000 and the repair is $12,000 on a machine worth $20,000, you need to run the math, not the emotion.

Before you order any part, check three things:

• Compatibility with your serial number, not just the model name. Manufacturers change components mid-production. I've been burned by this.
• Motor mounting dimensions. The same motor can have different flange patterns and shaft lengths. (I learned this the hard way with a $460 motor.)
• Return policy. If the supplier won't tell you what happens when it doesn't fit, assume you're keeping it forever.

I have mixed feelings about aftermarket parts. On one hand, they can keep an old machine alive for half the price. On the other, I've seen a $180 aftermarket motor draw enough current to fry a $500 controller. (Surprise, surprise.) The key isn't to avoid aftermarket; it's to buy from someone who can verify compatibility, not just match a photo.

Wisconsin buyers should also do a fifteen-minute frost check before ordering anything mechanical. A scrubber left in an unheated building overnight can freeze the recovery tank water, crack the pickup hose, or damage the vacuum motor. You might be paying for a new motor when the real fix is a heated storage space.

Wait, what about the Comac C919 engine manufacturer and price?

Now the search-term elephant in the room. You may have come here because you typed "Comac C919 engine manufacturer" or "Comac C919 price." That C919 is not a floor scrubber.

The Comac C919 engine manufacturer is CFM International, a 50/50 joint venture between GE Aerospace and Safran Aircraft Engines. The engine is the LEAP-1C, according to CFM's public product documentation. (Yes, that CFM makes aerospace engines. No, they don't make a floor scrubber motor.)

As for the Comac C919 price, public industry reports around the aircraft's certification cited a list price of approximately $99 million per aircraft. Actual transaction prices are negotiated and usually lower. If you're here for that, you don't need a floor scrubber buying guide. But if your boss asked you to look up "Comac" and you weren't sure whether it was aviation or cleaning equipment, now you know.

For cleaning equipment, the price question is different. A walk-behind Comac scrubber with battery and charger might run you $8,000-$20,000; a ride-on sweeper can be $25,000-$60,000. Those are ranges from quotations I've seen over the last 12 months, not a price list. The real cost is over five years: brushes, squeegees, batteries, motors, and downtime. That's why I keep saying the cheapest quote is usually not the cheapest machine.

How to know which situation you're in

Here's a five-minute self-check I give every buyer who asks "Which one should I get?"

1. Look at the floor at 7:50 a.m., before the first shift. Is it dry or wet? Dry and gritty → sweeper. Wet, sticky, or stained → scrubber.
2. Ask your crew which task eats more labor time. If they spend 90 minutes a day sweeping before the scrubber can run, you might need a better sweeper or a sweeper/scrubber combo.
3. Check the machine's newest symptom. Streaks are usually squeegee or vacuum. Missed debris near walls is usually side broom or brush speed. Dying mid-shift is usually battery or charging, not the main motor.
4. If you're still torn between a sweeper and a scrubber, consider a combination sweeper-scrubber. But it's heavier and more complex, so skip it if your operator isn't comfortable with routine maintenance.
5. If you actually need aircraft pricing, this is the wrong page. (Not that I'd blame you for double-checking.)

There's no universal answer, and anyone who tries to give you one before seeing your floor is selling, not advising. Start with the condition of the floor, then the motor specs, then the repair-versus-replace math. And if the search result says Comac C919, remember: one Comac builds jets, the other builds floor machines. Both are worth respect, but only one of them belongs in your facility.

If you're buying for a small shop, don't let a parts supplier make you feel like $200 is too small. Today's small order is next year's fleet order. I still buy from the people who treated me right when I was a nobody buyer.
