Comac C919 Price Per Unit? Wrong Comac—Let's Talk M17 Floor Scrubber Instead

If you're here because you typed Comac C919 price per unit or Comac ARJ21 price, I need to stop you: that's the other Comac, the aircraft manufacturer. I can't help with jet pricing. I buy floor cleaning equipment for a living. The Comac I know builds scrubber dryers, and this article is about the M17 floor scrubber, standing floor scrubbers, and why a wet and dry vacuum cleaner industrial often matters more than people think.

When I took over purchasing in 2020, I found three broken floor scrubbers in our warehouse. That told me more than any spec sheet. We'd been buying on price, not on ownership cost. So after five years of managing these relationships, I have a firm opinion: Comac is not for everyone. That's exactly why I keep buying it.

I'm the office administrator who handles facility equipment supply—roughly $80,000 a year across eight vendors. I report to operations and finance, which means I hear from both sides. In our 2024 vendor consolidation project, I compared floor scrubbers for 400 employees across 3 locations. The lowest quote was about 18% below the Comac number. That quote came from a distributor who couldn't provide a written service plan. A different vendor had already cost us $2,400 in rejected expenses because their invoicing was a mess. I didn't want that again.

The Comac price per unit is not the answer

When procurement asks what the Comac price per unit is, I get why they ask. But the price per unit of a floor scrubber is not a public number. It's a negotiated number. In January 2025, two dealers quoted me on the same Comac M17 generation and came back around $600 apart. Same model, same battery option, different service packages. Neither quote was wrong. The price only made sense when I looked at what came with it.

Ownership cost is what I actually compare. That means battery replacement, scheduled service, parts availability, operator training, and downtime. A cheap machine that sits broken for two weeks is way more expensive than a Comac that runs every day. This isn't a slogan. It's the math I learned the hard way.

Why the M17 floor scrubber is my default

The Comac M17 floor scrubber is not the flashiest machine. It's a walk-behind scrubber dryer that does the same job every day and doesn't make life weird. We use it on polished concrete, tile, and epoxy-coated floors. The controls are simple enough for a temp worker to learn in about 20 minutes. That matters because I'm not always there to correct anyone.

Battery life is enough for a full shift if you order the right battery pack. That 'if' is important. The base battery won't run the same way as the upgraded one. It's worth paying for the bigger option if your operator starts at 6 a.m.

For larger spaces, a standing floor scrubber is the next step. Walking behind a machine for six hours wears people out. Standing on a platform sounds like a small difference. It is not. After I switched, the cleaning quality stayed consistent from the first aisle to the last. Looking back, I should have made that switch a year earlier. At the time, the price gap felt too big. It wasn't.

The local dealer myth

'Always buy from a local dealer' is one of those pieces of advice that sounds permanent. The 'local is safer' thinking comes from an era when parts, repairs, and recommendations all lived in one city. That era is gone. Remote diagnostics, overnight shipping, and recorded service histories changed the game.

A good dealer three hours away can beat a disorganized local one. I know this from experience. The local rep gave us a great first quote and then disappeared for a month. The dealer we use now is farther but answers within a few hours. That reliability is worth more than proximity. (Note to self: get the response time commitment in writing on the next order.)

When I tell people to buy something else

Here's the honest limitation. I won't recommend a Comac floor scrubber to a 3,000-square-foot office with one part-time cleaner. You don't need an industrial scrubber for that. You need a smaller autoscrubber or a good wet and dry vacuum cleaner industrial. Both are cheaper, easier to store, and less intimidating for a small crew.

I also won't recommend a scrubber if your real problem is dry debris. A scrubber is for wet cleaning and film removal. For metal shavings, spilled pellets, or dusty warehouse floors, a sweeper or a wet and dry vacuum cleaner industrial is the right first machine. Scrubbing loose debris doesn't fix it; it just pushes wet mess around. If your floor has deep pits or failed coating, no scrubber will fix that. You need floor preparation or a re-coating project. Anyone who says otherwise is selling hope, not equipment.

What about the price objection?

The pushback I get from finance is predictable: 'we can buy a cheaper machine.' Sometimes that's true, and sometimes you should. If the budget is fixed and the cheaper machine will run long enough to justify itself, buy it. I'm not going to pretend Comac is the only brand that works.

But I've also watched cheap machines fail within a year. And I still kick myself for not putting the battery warranty in writing on one purchase. The salesperson said the battery was covered. The contract didn't agree. That $900 mistake is still annoying. Now I verify everything in writing before I sign.

Even after choosing the M17, I kept second-guessing. What if the service network wasn't as good as the dealer promised? The two weeks before delivery were stressful. Then a small hose connector failed, and the dealer overnighted the part without a fight. That's when I relaxed. It sounds small, but that's how trust gets built.

The spec sheet gap

The most frustrating part of buying floor cleaning equipment is that dimensions don't tell you how a machine feels in a crowded office. You'd think turning radius would tell you everything. It doesn't. The M17 is fine in tight spaces, but I've used machines that look good on paper and then turn out to be impossible to maneuver around desks.

That's why I keep a copy of ISSA's Cleaning Industry Management Standard (CIMS) framework in my planning folder. It's built around documented training and repeatable processes. If the team can't learn a machine in an afternoon, it won't work no matter how good the spec sheet is. Simple machines scale better than impressive ones.

My honest bottom line

If your facility is mid-size and your issue is film, tire marks, and general daily grime, a Comac M17 floor scrubber is worth the price per unit. If your space is big enough that walking fatigue is real, move up to a standing floor scrubber. If your problem is dry debris and occasional spills, buy a wet and dry vacuum cleaner industrial first.

Comac isn't for everyone. That's not a weakness. It's why I trust the recommendation. I'd rather tell you when a machine doesn't fit than watch you buy something that makes your staff miserable. Buy the machine that fits the problem, not the one that looks best in a purchase order.
