Comac Scrubber Dryer Buying Checklist: How to Pick a Small Walk-Behind Industrial Floor Scrubber (2025)

Before you start: what comac c919 price per unit has to do with this

If you arrived from a search for comac c919 price per unit, take a second to check what you're pricing. Comac S.p.A. makes commercial cleaning equipment. The C919 is a passenger aircraft from a separate manufacturer with a similar English name. This article is about the floor scrubber side. If that's what you need, keep reading. If you're pricing the plane, this checklist will not help.

I manage purchasing for a 400-person facility. About $150k a year in cleaning supplies and equipment runs through my desk. I'm not a technician, and I'm not a salesperson. I'm the one who gets called when a machine leaves streaks in the warehouse aisle.

This is the checklist I use now. It has six steps, plus the mistakes that show up in almost every project.

Step 1: Match the machine size to the floor, not to the brand

Start with the floor, not the logo. In my experience, a small walk-behind industrial floor scrubber handles cleaning areas of roughly 10,000 to 25,000 square feet per day in a normal facility. If you're cleaning more than that in one shift, a stand-on or ride-on machine is more realistic.

Last year we consolidated orders for three locations. One manager was convinced he needed a ride-on machine because the warehouse felt big. Measured it: 14,000 sq ft. The added speed wouldn't pay for the extra cost. A walk-behind was enough.

If you're replacing a mop-and-bucket setup, 'mop floor scrubber' is sometimes used to describe these small walk-behinds. The point is the machine scrubs and picks up the water in one pass. It's not a mop. A mop still has a place, but not for 30-foot warehouse aisles.

Step 2: Spend time on floor scrubber squeegees

Here's the thing: the machine is only as good as its squeegee. You can spend a lot on a Comac scrubber dryer and still leave a wet film if the squeegee is worn or adjusted wrong.

Floor scrubber squeegees are the rubber blades that sit behind the brush and pull the water off the floor. When I took over purchasing in 2020, I treated them as an afterthought. Then I approved a machine without an extra squeegee set. The machine was down for three days while we waited for a blade. Three days of a wet floor in the middle of a production floor. That's not a maintenance issue; that's a purchasing issue.

Buy a spare squeegee set with the machine. If the vendor says you won't need it for months, remind them that months always come. The cost is small. The downtime isn't.

Check the squeegee setup before you sign. Does it angle the blade correctly? Are the floor scrubber squeegees available from a local dealer, or do they have to ship from another country? Can you flip or replace the blades without tools? That last one matters more than you'd think.

Step 3: Match the battery to the shift, not just the longest runtime

Batteries are where people get excited about numbers. I get it. But runtime should match how the machine is used, not the maximum spec on the brochure.

A small walk-behind industrial floor scrubber with a 4-hour runtime sounds great. In a real shift, you'll stop to fill water, empty dirty water, move pallets, maybe let a manager test-drive it. I've learned to look at the charge cycle instead: can it charge in a normal overnight window without a special outlet? Is the charger compatible with your facility voltage? If you run multiple shifts, do you need a spare battery or a lithium option?

In 2024, we swapped a walk-behind from AGM to lithium because the operator had to stop an hour before the end of shift to charge. That hour of lost cleaning cost us more per month than the battery upgrade did. It took me five years of managing this stuff to understand that the 'best' machine is highly context-dependent. This is one of those contexts.

The fundamentals haven't changed—clean water, charged battery, maintained squeegee—but the execution has. As of 2025, the small walk-behind market is quieter and more battery-friendly than it was in 2020.

Step 4: Ask for a spare parts price list before you order

This is the step most buyers skip. Ask the dealer to email a spare parts price list with the quote. Not the operator manual—the price list.

In Q3 2024, I asked five vendors for the same thing: a Comac scrubber dryer quote and a list of the top ten spare parts with lead times. One vendor couldn't provide a list until after the order. Another sent a list with no prices and said 'call us' (which, honestly, was all I needed to see). The vendor we chose had the list in the quote package. It included floor scrubber squeegees, brushes, filter, drain hose, and a few common electrical parts.

Why does that matter? Because the cheapest machine can become the most expensive one if the squeegee costs $180 and takes eight weeks to arrive.

This is also where I made my classic rookie mistake. In my first year of buying, I ordered from a vendor because the unit price was about 15% lower. The machine was fine. The support wasn't. We couldn't get a straight answer on lead times, and the invoice came through with a handwritten receipt. Finance rejected the expense report. I ended up paying part of that out of the department budget. Now I verify invoicing, support, and parts before I order. Actually, let me rephrase that: before I even ask for a quote.

Step 5: Test the service story, not just the machine

You can't test a service network at a trade show. But you can ask a few specific questions:

• Who repairs this in my area? Is the service tech an employee of the dealer or a subcontractor?
• What's the expected response time for a machine down?
• Do they stock the most common consumables on-site?
• Will they train my staff on basic adjustments?

The answers tell you more than the brochure. A machine that's reliable in a warehouse is only reliable if the local dealer can support it. Don't ask if the machine is 'good.' Ask who fixes it when it's not.

One more thing: get it in writing. When I had two hours to decide before budget-year-end in 2024, I bought from a dealer we already used. Normally I'd want three bids, but there was no time. The machine worked out, but only because we had the support agreement in writing. If I hadn't pushed for that, I could have been standing over a wet floor with nothing to show for it.

Step 6: Calculate the total three-year cost, not the purchase price

Here's a simple way to compare machines. Use the sticker price, plus labor, battery replacement, squeegees and brushes, and service over three years. Then divide by the square feet cleaned yearly.

Small walk-behind industrial floor scrubbers generally run from about $6,000 to $18,000, depending on battery, brush system, and dealer setup. That's based on manufacturer and dealer quotes I reviewed in March 2025. Verify current pricing before you make a decision—prices move.

A mop-and-bucket setup costs far less upfront. It also costs more labor. If a small walk-behind saves 10 hours a week in a facility where labor is $25/hour, that's $250/week. The payback is real, but only if the machine is actually used. That's why the steps before this matter. A machine that's too big, with the wrong squeegee, and no service plan, is an expensive clothes rack.

Common mistakes that keep coming up

• Buying floor scrubber squeegees only after the streaks start. You will need them. Order them early.
• Forgetting width constraints. Measure doorways and racking widths. A small walk-behind can still be wider than an aisle.
• Believing a mop floor scrubber replaces every mop. Keep a mop for tight corners and under furniture. The machine is for open floor.
• Ignoring water quality. Hard water kills squeegee performance faster than wear. Softening or filtration is not optional if your water is hard.
• Choosing batteries without checking the charger voltage. This sounds like a simple issue until you're paying an electrician to rewire.

Look, I'm not saying you need the most expensive option. I'm saying you need a machine that fits the floor, is backed by a real support network, and has squeegees you can get quickly. What was 'best practice' in 2020 may not apply in 2025. But the fundamentals are still the same: keep the floor dry, keep the machine clean, and buy the spare squeegee before you need it.

That's the checklist. It's not glamorous. It works.
