Take two Sydney sites with the same 1,200 m² of hard floor. One is a single open sports hall on sealed concrete. The other is a medical centre: one corridor, a waiting room and fourteen consult rooms, each behind its own door. On paper they need the same machine. In practice the hall rewards every extra centimetre of path width, and the medical centre punishes it.
This guide treats width as an engineering trade-off. It shows what each centimetre buys in coverage, what it costs in access, storage and handling, and how to pick a width band using the figures on Freshway's own listings.
Floor scrubber path width: the short answer
Pick the widest scrub path that still fits your narrowest regular gap with room to steer. As a starting point, under 35 cm suits washrooms and small shops, 35 to 45 cm suits offices and clinics, 50 to 61 cm suits schools and supermarkets, and 70 cm or more suits warehouses and large halls.
The rest of this guide breaks that rule into its parts: coverage, doorways, aisles, storage, then a site-by-site shortlist and a quick-reference table.
Width vs productivity: where the listed m²/h comes from
A theoretical productivity figure is simply scrub width multiplied by travel speed. You can check this against Freshway's listings. The Nilfisk SC800 is listed with a 710 mm scrub path, self-propelled travel up to 5.8 km/h and a theoretical 4,120 m²/h. 0.71 m × 5,800 m/h = 4,118 m²/h, so the listed figure is width times top speed. The SC2000 53B checks out the same way: 0.53 m × 6,000 m/h = 3,180 m²/h, exactly as listed.
Run the maths backwards and the listed rates turn out to assume very different speeds:
| Machine (Freshway listing) | Listed width | Listed productivity | Implied speed (m²/h ÷ width) |
|---|---|---|---|
| Hako Wizzard W34N | 315 mm | 350 m²/h | about 1.1 km/h |
| Nilfisk SC100 | 31 cm | 620 m²/h | about 2.0 km/h |
| Hako Scrubmaster B12 | 38 cm | 1,500 m²/h | about 3.9 km/h |
| Nilfisk SC250 | 34 cm | 1,438 m²/h | about 4.2 km/h |
| Nilfisk SC401 | 43 cm | 2,330 m²/h | about 5.4 km/h |
| Nilfisk SC550 CYL 51 / D 61 | 508 / 610 mm | 2,550 / 3,050 m²/h | about 5.0 km/h |
| Nilfisk SC800 | 710 mm | 4,120 m²/h | about 5.8 km/h |
The lesson for buyers: do not compare listed m²/h across brands as if they were measured the same way. Compare widths at the pace your operators will actually walk. At the same pace, coverage scales in a straight line with width. The SC550 is a neat example, because the 610 mm D 61 is 20% wider than the 508 mm CYL 51 and its listed rate is about 20% higher.
For a worked example, assume a steady 3 km/h on that 1,200 m² hall. A 34 cm path gives 1,020 m²/h, or about 71 minutes. A 51 cm path gives 1,530 m²/h, about 47 minutes. A 71 cm path gives 2,130 m²/h, about 34 minutes. These are theoretical times before turns, overlap between passes and tank stops. Freshway's walk-behind vs ride-on guide covers how far real shifts fall below the theory.
Doorways and lifts: the squeegee is the real width
The scrub path is not the width that has to fit through a door. The rear squeegee is usually wider, and the chassis may be wider again. Freshway lists the SC800 with a 710 mm scrub path but a 910 mm squeegee. The Nilfisk SC25 robot is listed at 36.6 cm scrub path and 59.0 cm squeegee, and the Hako Scrubmaster B75i WB 540 at 54 cm scrubbing and 86 cm squeegee.
Compare that with the doors. The Australian Glass & Window Association's AS 1428.1 guide sets out a minimum clear opening of 850 mm for doorways on a continuous accessible path of travel. The same guide notes that not every door in a building has to meet that figure. A 910 mm squeegee is wider than an 850 mm opening, so ask how the squeegee lifts or comes off for transport, and measure your actual doors rather than assuming.
Lifts add two more checks: the car's internal size and its rated load. Listed weights climb quickly with width. The SC351 is listed at 80 kg including battery, the SC401 at 151 kg including batteries, and the SC2000 53B at 340 kg gross. Compare the figure with the load plate in the lift car before the machine is booked for an upper floor.
Aisles, furniture and the narrowest gap
No single aisle figure suits every scrubber, so the working rule is your own measurement. Walk the site with a tape and record the narrowest regular gap: between shelving, consult-room beds, café tables or toilet pedestals. Then compare it with the listed overall width, not the scrub path. Freshway lists the SC351 at 475 mm wide overall for a 37 cm path, and the Hako Wizzard W44P at 540 mm wide for a 420 mm path.
This is the core trade-off: a wider machine covers open floor faster but struggles in tight rooms. SafeWork NSW lists cluttered or inadequate space to perform tasks among the contributors to slips, trips and falls. A machine that cannot reach a room leaves that floor to a mop and a wet finish.
Edges matter as much as aisles. The Hako Scrubmaster B12 is listed with a protruding disc brush unit for cleaning up to the edge, which reduces manual touch-ups along skirting and shelving.
Storage footprint, weight and charging space
Width adds length and weight, and every machine needs a home. Multiplying the listed length by width gives the floor space it parks on:
- Kärcher BR 30/4: 550 × 300 mm, about 0.17 m², with a handle that folds flat.
- Nilfisk SC351: 770 × 475 mm, about 0.37 m².
- Nilfisk SC2000 53B: 1,270 × 550 mm, about 0.70 m².
- Nilfisk SC6000 910C: 1,780 × 1,170 mm, about 2.08 m², plus clearance to walk around it.
Battery machines also need a charging spot. SafeWork NSW's lithium-ion battery guidance calls for chargers designed for the battery type and voltage, and safe work procedures that cover storage and charging. Plan that space before the delivery arrives.
Weight also changes the operator's job. SafeWork NSW lists forceful pushing and pulling among hazardous manual task risk factors. A 12 kg SC100 (empty) and a 75 kg SC500 (net) are very different machines to manoeuvre, lift into a van or turn at the end of a row. At the 70 cm end, machines such as the SC800 and the Kärcher BR 75/75 W are listed with traction drive.
Starter recommendations by site
These are starting bands, not final answers. Each example comes from a current Freshway listing.
- Washrooms, cafés and boutiques (under 35 cm): Hako Wizzard W24N (215 mm listed cleaning width), Kärcher BR 30/4 (300 mm, 11 kg empty), Nilfisk SC100 (31 cm, carpet kit included).
- Offices, clinics and childcare (34 to 45 cm): Nilfisk SC250 (34 cm, lithium battery), SC351 (37 cm), Hako Scrubmaster B12 (38 cm), Cleanstar MIRA 40 (410 mm).
- Schools, supermarkets and open-plan floors (50 to 61 cm): Nilfisk SC500 (510 mm), SC550 (508 or 610 mm), SC2000 53B micro ride-on (53 cm).
- Warehouses and large halls (70 cm and above): Nilfisk SC800 (710 mm), Kärcher BR 75/75 W (750 mm), Nilfisk SC901 (860 mm), SC6000 910C (91 cm).
Many sites end up with two widths: a wide machine for the open floor and a compact one for washrooms and small rooms. Corded compact machines bring a cord into the picture. The BR 30/4 is listed with a 12-metre cable, and WorkSafe Victoria advises removing loose objects such as electrical cords from walk areas. Corded machines also need regular testing: SafeWork NSW's electrical risks fact sheet gives commercial cleaning equipment as an example for inspection and testing at least once every six months.
Spec-sheet fields to check on a floor scrubber
- Scrub path, squeegee width and overall width, listed separately where possible.
- Model name vs listed width. Freshway lists the Wizzard W44P as a 44cm machine class with a 420 mm cleaning width, the W34N as a 34cm class at 315 mm, and the W24N as a 24cm class at 215 mm. Use the listed cleaning width in your maths.
- What the m²/h figure assumes: divide it by the width to see the implied speed.
- Length × width for storage and lift space.
- Weight, and whether it is empty, net or filled. The B12 is listed at 80 kg filled including battery, while the SC100 is listed at 12 kg empty.
- Tank litres against width. A wide path empties a small tank fast; see Freshway's recovery tank sizing guide.
Common mistakes to avoid
- Sizing to the biggest room and forgetting the smallest door on the route.
- Comparing listed m²/h figures that assume different speeds.
- Measuring the scrub path but not the squeegee.
- Buying width the operator cannot comfortably turn at the end of each row.
- Leaving no charging or parking space for the machine.

Frequently asked questions
Isn't a wider scrubber always faster?
Only on open floor. Turns, doors and furniture eat into the gain, and a machine that cannot get into a room cleans nothing there. Width pays where passes are long and straight.
Can't one 50 cm machine cover the whole building?
Sometimes, if every door, lift and aisle clears it. Many sites still need a compact machine for washrooms and small rooms, because a wide machine leaves those floors to a mop.
Does 44cm in a model name mean a 44 cm path?
Not always. Freshway lists the Hako Wizzard W44P as a 44cm machine class with a 420 mm cleaning width. Use the listed cleaning width for coverage maths.
Is the scrub path the width that has to fit through the door?
No. Check the squeegee and overall width too. The Nilfisk SC800 is listed with a 710 mm scrub path but a 910 mm squeegee.
