Tennant T1, T1B, and Old Floor Scrubbers: 7 Questions I Answer Every Quarter

Eight years managing the equipment budget for a 260-person food distribution company. Roughly $340,000 a year across everything from forklifts to floor care — and floor care is where the surprises live. Two walk-behind scrubbers, one rider, one pressure washer, and a parts shelf I've rebuilt three times.

These are the questions I get from other facility and procurement folks, worded the way they actually ask them. Short answers. No sales pitch.

• Is a Tennant T1 or T1B right for a small facility?
• Which floor scrubber attachments pay for themselves?
• Old floor scrubber: repair or replace?
• Why do two identical quotes come out $3,000 apart?
• Can a pressure washer with a snow foam cannon replace a scrubber?
• What's hiding in a cheap scrubber quote?
• What should I check before I sign?

1. Is a Tennant T1 or T1B the right machine for a small facility?

Usually yes — but measure first. That's the step people skip.

We picked up a T1 in 2021 for what was then a 9,000 sq ft hard-floor area. Two years later we added a mezzanine and a second break room, and suddenly we were doing two tank dumps per shift. The machine was fine. Our estimate of the job was wrong.

So before you look at model numbers, measure three things: cleanable hard-floor square footage, the longest single run without a water source, and how many minutes your crew realistically spends per shift. Under about 10,000 sq ft with normal traffic, a compact walk-behind is basically a no-brainer. Past that, do the math on tank capacity and runtime against your actual area — not the brochure's.

Whichever letter suffix you're comparing, the questions are the same: square feet per tank, square feet per charge, and how fast can somebody swap a battery mid-shift.

2. Which floor scrubber attachments actually pay for themselves?

Four things, in my experience. Everything else is optional.

• The right squeegee blade compound. Cheapest performance upgrade there is. Wrong blade for your floor means streaks you'll blame on the machine for a year.
• Side skirts or splash guards. Keeps water out of aisles and away from pallets. Small cost, avoids a slip claim (which, honestly, is the expensive part).
• A second battery or a fast charger. This is a productivity attachment, not a maintenance one. Scrubber downtime is mostly charging time, not repair time.
• Pad drivers if you run mixed floor types. Pads and brushes aren't interchangeable in practice, even when the spec sheet suggests they are.

What doesn't pay back: the specialty kit for a floor type you see twice a year. We bought one in 2020. It's still in the box.

3. My scrubber is 11 years old. Repair it or replace it?

Two years ago I had this exact call. Repair quote came in around $1,850. Comparable new machine: ballpark $9,200. The old unit was worth maybe $1,500 as-is.

On paper, repair. Obviously.

But the upside of repairing was saving roughly $7,000. The risk was a mid-shift failure during our busiest week. I kept asking myself: is $7,000 worth potentially shutting down the pick line for a day? We repaired it anyway. It failed again five months later for another $700, and we bought the new one in Q2 2024.

The other machine in that same audit was 13 years old and still running fine. So it isn't an age thing. Here's the rule I use now: if the repair exceeds 25% of replacement cost and the machine has had two or more failures in the last 12 months, replace it. If it's had one clean failure and the rest of the machine checks out, repair is usually the right call.

4. Why do two quotes with identical specs come out $3,000 apart?

It's tempting to think you can just compare unit prices. But identical specs from different sellers can produce wildly different outcomes, and the gap is almost never in the machine itself.

We ran this on a mid-size walk-behind in 2023 — the regional dealer versus a national online seller. The online price was $2,900 lower. Then I built the three-year number.

• Freight and liftgate delivery: $420 on the online quote, included by the dealer
• Service labor rate: $148/hr through the online network, $112/hr at the dealer
• Travel charge per service call: $95 online, $0 at the dealer
• Battery replacement in year three: same part, 22% higher through the online channel

Three-year difference flipped to roughly $1,400 in the dealer's favor. Not dramatic. But it took me two weeks and a spreadsheet to find out, and the cheaper option had already been approved by someone above me.

I went back and forth on that one longer than I should have. The online price was real. So was the fine print.

5. Can a high pressure washer water gun with snow foam replace a floor scrubber?

No. Different jobs. Anyone who tells you otherwise hasn't had to re-mop a production floor at 6 a.m.

A high pressure washer water gun with a snow foam cannon is a vehicle and equipment tool. We use ours on the truck fleet and on dock equipment — the foam clings, dwells, rinses clean, and you use less water than bucket-and-brush. It's genuinely good at that.

Where a pressure washer earns its keep on a facility: dock aprons, dumpster pads, trench drains, exterior concrete. Not finished interior hard floors. Two reasons — water volume (a floor machine uses gallons; a pressure washer uses tens of gallons) and finish damage. High pressure strips sealer and can etch grout. We learned that on a 400 sq ft section in 2019 that cost $600 to redo.

One more thing. If a rep claims an attachment lets you "clean with water only" or that a chemical is "environmentally friendly," ask for the substantiation. Per FTC Green Guides (16 CFR Part 260), environmental claims have to be backed up. In my experience, about half of them aren't.

6. What's hiding in a cheap scrubber quote?

Seven things, ordered by how much they've cost us:

1. Battery replacement — often 20-30% of the original machine price, landing in year three or four when nobody's looking
2. Freight and liftgate fees on delivery
3. Service travel charges, per call
4. Proprietary parts you can't source anywhere else
5. Telemetry or fleet software subscriptions
6. Operator training, billed hourly
7. Wear items — squeegees, brushes, filters — at list price instead of contract price

That last one is the quiet deal-breaker. A squeegee blade you replace four times a year at $60 over contract price is $240 a year, per machine. Multiply by your fleet and it stops being a rounding error.

Bottom line: the sticker price is the least interesting number in the quote.

7. What should I check before I sign anything?

This is where the whole article lives, honestly. My checklist is six items and it takes about fifteen minutes:

1. Does the quote include delivery, setup, and an operator walkthrough — in writing?
2. What's the battery replacement cost, and what's the expected cycle life?
3. Is the service labor rate locked for the contract term?
4. Are wear items on a stated price schedule, or "market rate"?
5. What's the guaranteed response time for a down machine — hours or days?
6. Who does the work: a factory-trained tech, or a subcontractor?

Every one of those questions has a $500-plus answer attached to it. Five minutes of verification beats five weeks of arguing about a warranty claim.

The sixth one — who does the work — is the item people skip. Ask it.
