facility cleaning equipment

Most buyers compare the Jiechi A7 and the M20 the same way they compare anything else: price on one side, cleaning width on the other. Both numbers mislead you here. The A7 — a dual-brush ride-on floor scrubber — is not the cheap option, and the sweeper-scrubber combination machine is not the wide one. They are the same machine with one component added, and that component decides whether your floor gets worked once or twice. Below: the three real spec differences, what the hopper picks up and jams on, how throughput changes with debris on the floor, and a ten-minute test you can run tonight. Quick Answer The A7 and the M20 share the same chassis, battery, brush motors and 5,500 m²/h rating, so either one fits the same site survey. The only real choice is whether you need the M20's 20 L front hopper. If dry, loose debris lands on your floor every shift — cardboard dust, stretch wrap, grit, wood chips — the M20 sweeps it up before scrubbing and removes an entire pass from your routine. If your floor stays dry-clean or is wet by nature, buy the A7 and keep 10 L more water capacity. Key Takeaways Identical 165 × 90 × 130 cm chassis, 330 kg, 24 V / 200 Ah battery, 560 W × 2 motors, 5,500 m²/h rated — every site constraint (doors, lifts, ramps, charging bay) applies equally to both. Three real differences: the M20's deck is 40 mm wider, its tanks hold 10 L less each, and it carries the 20 L debris hopper. The hopper's value is pass removal, not width: on a debris floor the A7 needs a sweep pass and a scrub pass, while the M20 finishes in one. On normal warehousing debris the bin is emptied far less often than the tank is refilled — the hopper rarely becomes the machine's limiting cycle. The hopper cannot be retrofitted onto an A7 later, so decide before you buy, not after the first season of complaints.

Read the last five rows first — they are identical, and that is the point. Specification A7 — scrubber M20 — sweeper-scrubber Brush deck width 860 mm 900 mm Solution / recovery tanks 140 L / 150 L 130 L / 140 L Debris hopper — 20 L Rated coverage 5,500 m²/h 5,500 m²/h Battery 24 V / 200 Ah 24 V / 200 Ah Brush motors 560 W × 2 560 W × 2 Machine weight 330 kg 330 kg L × W × H 165 × 90 × 130 cm 165 × 90 × 130 cm Same chassis, same battery, same rated output. The M20 adds a sweeping roller and a 20 L bin ahead of the brush deck. Three differences, no more: a brush deck 40 mm wider, tanks 10 L smaller, and a 20 L hopper. Everything the site survey hinges on — doors, lifts, ramps, charging bay, mezzanine load limit — is unchanged, and a 90 cm doorway rules out both in exactly the same way. The parts picture is almost as tight: brushes, pads and squeegee blades sit in the same deck family, so a storeroom stocking for one largely covers the other. The hopper assembly — roller, bin, filter — is the only stock the M20 adds. That matters at negotiation time too: the supplier's cost difference is one component, not a machine class, so ask for itemised quotes. The 20 L debris hopper and what it really picks up The hopper sits ahead of the brush deck. A roller lifts loose material into a 20 L bin, and only then does the deck lay down solution and scrub. That order matters more than the capacity number, because it means debris leaves the floor dry, as debris, instead of being wetted, crushed and smeared into a slurry your squeegee then has to chase. The hopper's home turf: dry, loose material that a sweeping roller can lift before the deck ever touches it. What goes in and what does not is the honest part of the decision, so here it is without marketing: Debris on your floor 20 L hopper Note Cardboard dust, paper, cores Picks up The main warehouse case Stretch film, pallet wrap Picks up Light film can tangle; clear it before it balls up Wood splinters, pallet chips Picks up Up to roughly 30 mm Entrance grit, small gravel Picks up The reason retail floors stay scratch-free Wet leaves, mud, caked soil Partial Sticks to the bin; needs a manual clear Standing water, oil, slurry No That is the deck's job, and both models do it String, cable, twine, wire No Wraps the roller — the one real operating risk Fine sand under 1 mm Partial Needs a slower pass, do not run at full speed Read that table against your own floor and the decision usually becomes obvious. Dry and loose most of the time, and the hopper works every shift; wet by nature — a washdown area, a bottling line — and it sits empty. In textile, packaging and cable operations the roller will pick up strapping within minutes — that is what a sweeping roller does, not a defect. Plan a two-minute check at every water stop. Throughput on a clean floor vs a debris floor Both machines are rated at 5,500 m²/h. On a clean, sealed floor that rating is the whole story: same speed, same deck class, same result — and paying extra for sweeping capacity you never use buys nothing. On a debris floor the rating stops meaning the same thing, because the A7 now needs two passes. Either a second operator takes a walk-behind sweeper ahead of it, or the scrubber pushes debris into a wet strip the squeegee drags along. Whichever way you arrange it, the work happens twice. One visit or two: the debris that forces the A7 into a second pass is gone before the M20's deck touches the floor. Across a shift, the debris row is the only one that matters: the M20 finishes in one pass what the A7 finishes in two. Even when a walk-behind sweeper handles the pre-sweep, its pace is slower than a ride-on's, so the gap narrows but never closes. Debris problems are rarely solved by buying a wider scrubber — a 1,060 mm deck still needs the debris gone first. Width buys speed on clean floors; only the hopper removes the pass. Water and hopper stops: two cycles instead of one Now the cost side, and it is smaller than the throughput gain. Because the hopper occupies volume inside the same envelope, the M20 carries 10 L less solution and recovery water — slightly shorter runs between refills, usually the only operating penalty of the combination. In practice, on normal warehousing debris the bin is emptied far less often than the tank is refilled, so the M20 does not add a stop to your shift — you empty the bin while you refill the tank, one stop doing two jobs. On a genuinely filthy floor the rhythm can flip. That is not a reason to reject the machine — just check the bin rhythm in week one, not month three. Which floor type makes the decision for you Most buyers do not choose on economics — they choose on what is on the floor at 7 a.m. Match your situation to the row below and the answer is usually settled before the quote arrives. Your floor Buy Why Sealed concrete warehouse, cardboard dust, wrap M20 The debris is the whole problem, not the floor Food plant, washdown area, wet slurry only A7 Nothing dry to pick up; keep the 140 L Supermarket or mall, entrance grit and paper M20 Grit at the doors scratches the finish Showroom, polished floor, dust only A7 A dust mop handles the dry work for less Mixed multi-tenant industrial park M20 You cannot control what tenants drop Textile, packaging, cable operations A7 plus manual sweep String wraps any sweeping roller Cold store below −10 °C Neither Battery and ice behaviour differ — spec separately If you are still undecided, run a ten-minute test that settles it better than any brochure. Mark three 2 × 2 m squares — one at your busiest doorway, one mid-aisle, one where your worst mess happens. Sweep each into a dustpan and look at what you collect. Dry and loose in two of three, and the hopper earns its premium; sticky, wet or greasy in two of three, and the A7 is the better machine for the money. Whichever way the test goes, specify both machines the same way: brush type matched to your floor finish, squeegee blade material matched to your chemistry, spares quoted with the machine rather than after the first failure. Those details move lifetime cost more than the model choice. If your aisles are tighter than a ride-on allows, the walk-behind M16 combination machine does the same sweep-then-scrub job in a smaller footprint — the same logic, half the turning circle. Common Questions How much more does the M20 cost than the A7? The M20 adds a sweeping roller, a 20 L bin and a filter to an identical chassis, so the price gap should reflect that hardware, not a different machine class. Ask for both quotes itemised so the hopper appears as its own line — a premium with no breakdown deserves an explanation before you sign. Can I add a sweeping hopper to an A7 later? No. The hopper is built into the chassis ahead of the deck, with its own drive and bin, so it is not a bolt-on accessory. If debris is likely to become a problem within two years, decide now rather than buying twice. Will a 20 L hopper keep up with a large warehouse? On normal warehousing debris, yes: the bin fills far less often than the tank empties, so it is rarely the limiting cycle. On heavily loaded floors it fills faster — check it at every refill during week one. Does the M20 clean a wet floor as well as the A7? Yes. Both run twin 560 W brush motors on the same deck family, with a 900 mm deck on the M20 against 860 mm on the A7. The only wet-side difference is 10 L less solution and recovery capacity, which shortens the refill cycle slightly. Why does the M20 carry 10 L less water? The hopper and its bin occupy volume inside the same 165 × 90 × 130 cm envelope, and nothing was added to compensate, so the tanks gave up 10 L each — a deliberate trade for a shorter water cycle. Can one machine cover both a warehouse and the office area? It can, if office flooring is hard and sealed — though it will not replace a carpet extractor, and the hopper is unnecessary there. If offices make up more than a third of the total area, a smaller walk-behind alongside often costs less to run than forcing one machine to do both. Conclusion The A7 and the M20 are one machine and one component. Judge them on a single question: is there dry, loose debris on your floor every day? If yes, the 20 L hopper removes an entire pass and roughly doubles the floor you finish per shift on debris days. Ten litres of water is a fair price for that. If no, buy the A7 and keep the larger tank. The most common mistake here is not buying the wrong machine — it is paying for sweeping capacity that never gets used. Not sure which one fits your floor?

Choosing a floor scrubber isn't just about picking the most expensive model or the one with the flashiest features. The single most important factor is matching the machine to your facility's size. Get this wrong, and you either overpay for capacity you don't need or end up with a machine that can't finish the job before running out of battery or water. In this guide, we break down the three critical specs — tank capacity, cleaning width, and battery life — and show you exactly how to calculate what your facility needs. Why Facility Size Matters for Floor Scrubber Selection Every cleaning manager has faced this scenario: a brand-new scrubber that runs out of water halfway through the warehouse, or a machine that takes twice as long as expected because the cleaning path is too narrow. The root cause is almost always the same — the machine was chosen without matching its specs to the actual floor area. Here's a quick decision framework based on facility size: Small (retail shops, offices, clinics, under 5,000 sq ft): Walk-behind scrubbers (16–20 inch), 10–13 gallon tank Medium (schools, hotels, supermarkets, 5,000–20,000 sq ft): Walk-behind scrubbers (20–28 inch), 13–20 gallon tank Large (warehouses, factories, airports, 20,000–100,000+ sq ft): Ride-on scrubbers (28–36 inch), 20–40+ gallon tank Note: Tank capacity varies by brand and model. Always check the manufacturer's spec sheet. 1. Tank Capacity: How Much Floor Can You Clean Per Refill? Tank capacity determines how long you can clean without stopping to empty the dirty water tank and refill with fresh solution. This is arguably the most overlooked spec in floor scrubber selection. The rule of thumb: A floor scrubber typically covers about 10–15 square feet per gallon of solution, depending on the floor type. Porous floors (like unsealed concrete) consume more solution, while smooth floors (like tile or sealed concrete) use less. Example calculation: A 10-gallon machine ≈ 100–150 sq ft per tank A 20-gallon machine ≈ 200–300 sq ft per tank A 40-gallon machine ≈ 400–600 sq ft per tank For a 50,000 sq ft warehouse, a machine with a 40-gallon tank would require about 3–4 refills to complete a full cleaning cycle. That's significant downtime. Here's the bottom line: If your facility requires more than 3 tank refills per cleaning session, consider upgrading to a larger-capacity model. 2. Cleaning Width: How Fast Can You Cover the Floor? Cleaning width determines productivity — wider means fewer passes, shorter cleaning time, and less labor cost. The simple formula: A 20-inch scrubber covers roughly 20,000 sq ft per hour (assuming 2.5 mph walking speed, 85% efficiency for overlap) A 28-inch scrubber covers roughly 28,000 sq ft per hour A 34-inch ride-on scrubber covers roughly 38,000–45,000 sq ft per hour What this means for your facility: Under 10,000 sq ft: A 17–20 inch walk-behind is sufficient. Cleaning takes roughly 30 minutes. 10,000–30,000 sq ft: A 24–28 inch walk-behind or compact ride-on. Cleaning takes 45–90 minutes. Over 30,000 sq ft: A 30+ inch ride-on scrubber. Cleaning takes 1–3 hours depending on layout. If your cleaning team spends more than 2 hours per day on floor cleaning, a wider scrubber could cut labor costs in half over the machine's lifespan. 3. Battery Life: Can Your Scrubber Handle Back-to-Back Shifts? Battery runtime is the third leg of the stool. Even with the right tank and cleaning width, a dead battery at the wrong time brings everything to a halt. Key battery considerations: Lead-acid batteries: Typically provide 3–5 hours of runtime, but require 8+ hours to charge plus cool-down time. Not suitable for multi-shift operations. Lithium batteries: Provide 4–6 hours of runtime and can be opportunity-charged during breaks (30 minutes of charging gives 1–2 hours of operation). Ideal for multi-shift facilities. For a 50,000 sq ft facility with a ride-on scrubber: Lead-acid: May not finish a full shift on one charge. Requires designated charging room with ventilation. Lithium: Can finish the job and be recharged in time for the next shift. Pro tip: If your facility operates on two shifts, skip lead-acid entirely and invest in lithium-powered equipment. The upfront cost is higher, but the productivity gain is substantial. How to Match Floor Scrubber to Your Specific Facility Here's a step-by-step approach to choosing the right scrubber: Measure your total cleanable floor area (exclude areas occupied by shelving, machinery, or storage) Estimate your cleaning budget (minutes per cleaning session and number of shifts) Calculate the minimum cleaning width you need to stay within that budget Determine required tank capacity based on frequency of refills your team can tolerate Choose the battery type that matches your shift schedule For example, a 30,000 sq ft warehouse with one shift: Cleaning width needed: 28+ inches (≤90 minute cleaning time) Tank capacity needed: 20–30 gallons (1–2 refills) Battery: Lithium recommended for consistent runtime across the shift Suggested machine: A walk-behind floor scrubber like Jiechi's JD-28B For a 100,000 sq ft logistics center running two shifts: Cleaning width needed: 34+ inches ride-on Tank capacity needed: 40+ gallons Battery: Lithium mandatory for opportunity charging between shifts Suggested machine: A ride-on floor scrubber like Jiechi's RS-36 Common Mistakes When Choosing a Floor Scrubber 1. Overestimating cleaning width coverage A 20-inch scrubber doesn't really clean 20 inches — subtract 1–2 inches for overlap Real-world efficiency is around 80–85% 2. Buying a scrubber that's too small Leads to operator fatigue from extra passes Increases labor costs over the machine's lifetime Often requires a second cleaning session to finish 3. Ignoring floor type and condition Rough concrete requires different pad pressure than smooth tile Uneven floors need larger squeegees or dual-squeegee systems for effective drying performance Solution consumption varies dramatically by floor porosity 4. Neglecting squeegee system quality A poor squeegee leaves streaks and wet spots, creating slip hazards Look for machines with adjustable squeegee pressure and tilt-back protection Final Recommendation There's no one-size-fits-all floor scrubber. The right choice depends on your specific facility size, floor type, shift schedule, and cleaning priorities. For small facilities (<5,000 sq ft): Compact walk-behind with lithium battery. Look for easy maneuverability around obstacles. For medium facilities (5,000–20,000 sq ft): Mid-size walk-behind with at least 20-inch cleaning width. Prioritize tank capacity and battery runtime. For large facilities (>20,000 sq ft): Ride-on scrubber with lithium battery and large tank capacity. Consider models with dual squeegee for better drying results and efficiency. Jiechi Cleaning offers a full range of floor scrubbers designed for facilities of every size — from compact walk-behind models for small shops to heavy-duty ride-on machines for industrial warehouses.
