How Do Touchless Restroom Cleaners Work?

Rod Michelini is the founder of OneUp Cleaning. We sell the Tornado, Clarke and EDIC machines named here and don't sell Kaivac, so where a mop still does the job better, this page says so.

A touchless restroom cleaner is a wheeled machine that sprays cleaning solution on fixtures, walls and floors, lets it dwell, pressure-rinses the loosened soil at roughly 400 to 550 psi, then vacuums the dirty water into a recovery tank. Nobody scrubs by hand, and the room is left clean and nearly dry, as long as the walls can take water.

If that's all you needed, you're done. Keep reading for the procedure and the part brochures skip: when your crew will find it slower than a mop.

What's inside a touchless restroom cleaner?

Kaivac says its founder built the first No-Touch Cleaning system by putting a pressure washer, chemical injection and a wet vacuum on one platform, and every machine in this category, including the ones we carry, still follows that design. The cart keeps your hands away from contaminated surfaces:

• Pump and gun: the low setting applies your chemical as a wide fan, and the high setting rinses it off.
• Chemical injector: colored metering tips control the dilution. On the Tornado, the pink tip meters 3 ounces per gallon, and you can match a tip to whatever chemical brand you already buy.
• Two tanks: clean water leaves one tank and dirty water returns to the other. Clarke's TFC 400 operator manual tells you to feed chemical only through the siphon, never into the tank, at a pH between 4 and 12.
• Wet vacuum, hoses and wand: the wand head carries a scrub brush on one side and a squeegee on the other.

Here's how the Clarke, EDIC and Tornado machines compare on their makers' own spec sheets, so you can see what each one gives you:

Suction is where these machines differ most. UCLA's ergonomics team rates it in airwatts, CFM times inches of water lift divided by 8.5, and recommends about 1,000 for a good result. By that formula the Tornado reaches 1,956 airwatts and the Clarke 924, just under that mark. EDIC doesn't publish an airflow figure for either CR2, but their 138 inches of water lift is the strongest here.

How does a no-touch cleaning system work, step by step?

Most no-touch cleaning follows the same routine, and Tornado teaches it as D.A.R.E., which stands for disinfect, agitate, rinse and extract. EDIC's four short training videos show every step on a real restroom, and they're worth watching before your first shift:

Set up and gear up

Pick up trash and loose debris, then test the GFCI on your cord before every use. Wear gloves and eye protection, because OSHA requires eye or face protection around liquid chemicals. Add waterproof shoes too, since people who run these machines warn that you will get wet.

Spray the solution on low pressure

Set your gun to a fan pattern and work one fixture at a time. On a urinal, EDIC's sequence runs from the chrome to the inside, the outside, the wall below and the floor. On a toilet, you coat the seat, hinges, underside, bowl, exterior and floor. Save mirrors for last so they don't streak.

Keep a quick pace, because every extra second on the trigger is water you'll vacuum later, and a custodial manager on Reddit says flooding the room is the usual reason a touchless clean drags on.

The manufacturers disagree on direction. Clarke's manual has you coat walls from the bottom up and spray the floor last on your way out, while EDIC starts at the top of each fixture, and either method works if your coverage is even.

Let it dwell, then brush the stubborn spots

Dwell time doubles as restocking time, and in one franchise's routine the chemical sits at least 10 minutes while technicians refill the dispensers.

This is also when disinfection happens, and the pressure has nothing to do with it. The EPA says to use a registered disinfectant, pre-clean visibly dirty surfaces and keep the surface wet for the label's full contact time. While you wait, flip the wand to the brush side and scrub under urinals and around toilet bases.

Rinse from the top down on high pressure

All three manufacturers agree on this step, so switch your gun to high pressure and rinse from the chrome down to the floor. On mirrors and sinks, open the spray back to a fan to reduce splashing and streaks. The first time you deep clean a restroom, run the stream along your grout lines as well. If the grout has gone dark over years, a spinner tool does more than a touchless rinse, and our professional tile and grout cleaning machine guide compares the options.

Vacuum the floor and dry the chrome

Squeegee the mirrors and counters so the water ends up on the floor, then vacuum with the squeegee side of the wand. EDIC and Tornado both have you start near the machine and work toward the back of the room, which keeps your vacuum hose clean and dry.

Finish by drying chrome and toilet seats with a blower tool, which the EDIC includes and Clarke sells as an option, or with a microfiber cloth. Skip that step and you'll find water spots on every fixture the next morning.

Is a touchless restroom cleaner faster than a mop and bucket?

For a deep clean, yes. For a light nightly clean, often not.

The industry figures look impressive. One cleaning franchise told CleanLink that a school restroom takes about 45 minutes by hand and about 15 with a touchless system, and Kaivac says your operators can clean one fixture per minute against an industry average of three.

Custodians who use these machines every night tell another story. In one r/Custodians thread, a school custodian said the machine consumed a third of his shift, about twice what hand cleaning took. Another building's trial took an hour on a restroom that normally takes 15 minutes, although the room looked amazing afterward. Across Reddit and YouTube, at least a dozen custodians describe running the machine weekly, on Fridays or during school breaks instead of every night.

Where both sides agree is the result. Custodians say the machine pulls urine odor out of grout and wall joints that a mop only wets, and one custodian in that thread suggests a test: mop a restroom, go over it with the machine, then look at what's in the recovery tank.

So who's right about speed? Both. A custodian with 17 years on the job says a trained operator finishes a 10 to 12 stall restroom in about 15 minutes, dwell time included, and another says it beats mopping once your crew learns the process. When your crew runs slow, look for these causes:

• Too much solution on the floor, which leaves more water to vacuum
• Hand wiping everything anyway, as if the machine were a mop
• A machine that's too big or too small for the room
• A floor that doesn't slope toward the drain

Your payoff grows with the size of your route. Cut a 30-minute restroom to 10 minutes and 20 restrooms give you back over six hours of labor, and our guide to whether a touchless machine is worth it works the payback math for your own restroom count. If you only have a handful of lightly used rooms, you'll get more from a weekly deep clean and a quick daily wipe in between.

Where won't a touchless machine work?

It won't work anywhere water causes damage, and it slows down wherever water can't drain away, so walk your restrooms and check for these conditions before you buy:

• Walls that can't take water: painted drywall, wood paneling and low exposed drywall around sinks and toilets rule the method out, according to both UCLA and Kaivac's own buying guide. Sealed walls such as tile are fine.
• Ceilings: even the franchise routine above covers everything except the ceiling.
• Floors that don't slope to a drain: the vacuum still picks the water up, but on an uneven floor the rinse water runs under partitions into stalls you've already finished, so you end up vacuuming the room twice. One custodian's fix is to close the next stall and angle the spray toward the one with the drain.
• Tiny single restrooms: laying out hoses can take as long as cleaning a one-toilet room by hand. There, a micro scrubber like the NaceCare 220NX handles your floor behind the toilet, and our guide to how to clean a restroom covers the rest of the routine by hand.

Which touchless bathroom cleaning system fits your restrooms?

Start with your rooms rather than the specification sheet:

1. Tank size: UCLA's equipment review says 8 gallons covers a 2 to 4 stall restroom, while rooms with about 8 stalls or showers need 15 gallons or more. The Tornado, the 17-gallon CR2 and the Clarke carry 15 or more, and the CR2 Jr carries 12.
2. Maneuverability: equipment specialists who sold these machines for years say a mid-size unit handles most restrooms, and the biggest are hard to park in a tight room. Weight runs from 86 pounds for the Clarke to 152 for the Tornado.
3. Power: all four are corded, and the 17-gallon CR2's 50-foot cord reaches twice as far as the 25-foot cords on the others.

Here's the route each one suits:

• Clarke TFC 400: the lightest machine with the largest solution tank, suited to schools and offices with many small restrooms on one floor.
• EDIC CR2: the highest pressure and the longest cord, with an optional carpet kit, suited to contract cleaners who move between buildings.
• EDIC CR2 Jr: the same pump, vacuum and tools as the CR2 in a 12-gallon body, suited to crews with a handful of restrooms per shift and a small closet to store it in.
• Tornado Touchless Cleaner: the strongest suction we can calculate, suited to locker rooms, stadiums and heavily soiled restrooms.

How do you keep a touchless cleaner working?

Empty and rinse both tanks at the end of every shift, and flush your hoses with clean water, especially after picking up stripping slurry. Check your metering tip for clogs and handle the wand head gently, since one retail custodian reports breaking four of the mounts that hold the squeegee and brush.

Frequently asked questions

Are restroom cleaning machines worth it?

Yes, if you clean many restrooms or deep clean on a schedule. Our guide to whether touchless restroom cleaning machines are worth it runs the payback math by restroom count.

Can you use any chemical in a touchless cleaner?

Mostly. The Tornado accepts any brand once you match the metering tip to your dilution, and Clarke limits you to a pH between 4 and 12. Your chemical's label must also allow spray application. Kaivac ties its longest warranty to its own chemicals, which is one reason buyers look at Kaivac alternatives.
