Comac Floor Scrubber FAQ: M30, Lavor, Soap, and the ARJ21 Price Confusion

I'm the office administrator for a 300-person operations center, and I manage all facility purchasing—roughly $240,000 annually across a dozen vendors. I report to operations and finance, so equipment decisions have to survive two very different kinds of scrutiny. When I took over in 2021, our supply closet had three unlabeled detergents and a stack of brushes that didn't fit half the machines. This FAQ is about the real questions I had when comparing Comac floor scrubbers, M30 specs, and cleaning chemicals—plus a few answers I wish I didn't have to learn the expensive way.

Is Comac the airplane company or the floor scrubber brand?

Both. Comac is an Italian floor scrubber manufacturer that has been around for decades. The other Comac is the Commercial Aircraft Corporation of China, the company behind the ARJ21 and C919 airliners. Same spelling, completely different industries. If you're searching for a ride-on scrubber for a warehouse, you're in the right place. If you typed 'Comac ARJ21 price' or 'Comac c919,' you're not the first person to land here. Our scrubbers don't come with wings.

What does a Comac floor scrubber cost?

The honest answer: it depends on the class. When I replaced our old walk-behind, I looked at three options and got quotes from roughly $8,000 for a basic model to over $30,000 for an autonomous unit. The compact ride-on we eventually picked landed in the middle. As of early 2025, that's the range I'd expect from a local dealer in our market.

But the purchase price is not the whole story. I'd estimate the machine itself was maybe 30% of what the first year ended up costing. Batteries, charger, pads, squeegee blades, detergent, maintenance, and operator training all add up. One quote looked great until I realized it didn't include the onboard charger, and the brush head didn't fit the pads we already stocked. I don't mean every expensive option is worth it; I mean the lowest upfront bid needs extra scrutiny before it becomes a decision. A dealer's job is to present a number that looks comparable to other quotes. My job is to check what the number includes.

Then run the labor math. If a ride-on saves two hours per day at an assumed internal rate of $35/hour, that's roughly $17,500 in avoided labor a year. Suddenly a $5,000 price gap between a walk-behind and a ride-on looks different.

What about the Comac ARJ21 price?

That's a different Comac. I can't give you a reliable ARJ21 list price because commercial aircraft deals aren't published the way floor scrubber prices are. The Commercial Aircraft Corporation of China negotiates each sale based on configuration, volume, and financing. If you typed 'comac arj21 price' while researching floor scrubbers, don't worry—you're in the wrong place, but you're not crazy. ARJ21 pricing is a completely different procurement universe, and not one I know well.

Comac vs. Lavor floor scrubbers: which is better?

I spent four weeks on this comparison before ordering. Both are established Italian manufacturers, and both make serious commercial machines. Rather than pick a 'winner,' I looked at which brand offered faster parts access in our region. Lavor has a solid dealer network and some well-regarded battery-powered models; Comac has a broad lineup that includes compact ride-on machines like the M30. In our case, the Comac dealer stocked the brushes and squeegees we needed locally, so we went that way. A colleague at a nearby facility runs a Lavor unit and has no complaints.

Here's the comparison checklist we used: brush width, tank capacity, battery runtime, noise level, pad availability, and dealer response time. The brand name only entered the conversation after those numbers were close. Local support should drive the decision more than brand loyalty.

Is the M30 floor scrubber worth it?

The M30 is one of those model names that gets searched often. I'll speak to our experience with the M30 class of compact ride-on scrubber-dryers. For a facility like ours—about 60,000 square feet of hard flooring—a full-size ride-on felt like overkill, and a walk-behind took too long. We demoed the smaller ride-on for a week, and the immediate reaction from the crew was 'when does this arrive?' It cut our daily cleaning time from nearly three hours to under an hour.

The trade-offs: smaller tanks mean more refills, and the cleaning path is narrower. If your space is mostly wide-open aisles, you'd want a wider machine. But a machine the team actually wants to use ends up being better than a bigger, heavier one they avoid. If you're looking at a used or ex-rental M30, factor in battery age. A new set of batteries can cost a third of a small used machine. We paid a little more for a new unit and didn't inherit someone else's battery chemistry problem.

What industrial floor scrubber soap should I use?

Use what the scrubber manufacturer specifies—and ignore the first cheap option. Our manual calls for a neutral pH, low-foam concentrate with a dilution ratio that looks too small to matter. I still kick myself for buying a generic floor soap once to save maybe $80. It foamed through the recovery tank, tripped the shutoff sensor, and cost me a full morning plus a $180 service call. The approved concentrate costs more per bottle but works out to under a dollar per cleaning cycle because you use so little of it.

Dilution matters too. If the machine has an auto-fill system, check the flow rate settings. We initially set the concentrate too high and went through chemical twice as fast. The manual's 'use half a cap per two gallons' isn't just a suggestion; it's a cost control.

Also, when a soap says 'green' or 'eco-friendly,' ask for the substantiation. Per FTC Green Guides (ftc.gov, 16 CFR Part 260), environmental claims need evidence behind them. That's a useful screen when cleaning chemical salespeople start using sustainability words loosely.

What hidden costs matter more than the sticker price?

Here are the ones that bit us:

Batteries: lead-acid packs need water checks, equalization charges, and replacement every few years. Lithium adds upfront cost but removes much of the daily maintenance.

Brushes and pads: they wear faster than expected, and the wrong pad can scratch or dull a floor.

Water hardness: hard water scales up the recovery tank and can turn a simple rinse into a service visit. A softener is worth pricing.

Downtime: our old walk-behind died in March 2023, mid-week. The rental was $450, and the shift supervisor still mentions it. The stalled cleaning schedule cost more than the repair.

Service: a dealer who answers the phone beats one who undercuts everyone by 5%. Operator training is also a hidden line item. A scrubber left with a dirty squeegee or the wrong pad eventually costs you a floor refinishing job. (Mental note: I still owe our rep lunch for the emergency battery delivery.)

The conventional wisdom is to minimize purchase price. My experience after 60+ cleaning equipment orders says the opposite: minimize the total cost of having a clean floor. I ended up with Comac not because it was the flashiest brand, but because the support, parts, and chemical setup made the total equation work.
