How to Choose a Commercial Floor Scrubber
A floor scrubber should fit the building before it fits the specification sheet. The right machine is the one that can move through the site, finish the route within the available shift, and leave the floor dry enough for normal traffic.
Short answer: choose a floor scrubber from the cleanable area, narrowest access point, working width, realistic hourly output, tank capacity, battery runtime, floor finish, brush or pad requirement, and water-recovery performance. Do not select from theoretical productivity alone.
Measure the building before comparing machines
Start with the area that can actually be scrubbed. Subtract shelving, counters, machinery, fixed seating and storage zones from the gross floor area. Then record the narrowest doorway, aisle, lift and turning point on the cleaning route.
| Site measurement | Why it matters | Common oversight |
|---|---|---|
| Cleanable area | Sets the real workload | Using the building’s gross area |
| Narrowest access | Limits machine and squeegee width | Measuring the scrub deck but not the rear squeegee |
| Turning space | Affects work around racks and furniture | Assuming a machine can turn wherever it can enter |
| Ramps and thresholds | Affect traction, clearance and operator control | Checking only level floors |
| Water and charging points | Determine refill, drain and charging time | Treating travel time as productive cleaning |
A compact machine may finish a congested shop faster than a wider model because it spends less time reversing, hand-mopping edges or moving furniture. Open warehouses usually reward a wider path and larger tanks.
Theoretical productivity is not completed floor area
Published productivity is often calculated from travel speed multiplied by cleaning width. It is useful for comparing machines under the same method, but it does not include turning, overlapping passes, filling, draining, battery changes, edge work or moving obstacles.
For planning, use: planned practical output = theoretical output × site efficiency factor. The efficiency factor should come from a route survey or trial, not a universal percentage. For example, a 3,000 m² cleanable area that must be finished in two hours requires 1,500 m²/h of practical output. A machine rated at 1,500 m²/h theoretically would not meet that target once turns, refilling and edge work are included.
Working width, squeegee width and machine width are different
The cleaning width describes the brush or pad path. The squeegee is normally wider so it can collect water during turns. The complete machine may also have guards, wheels or handles outside the scrub path. All three dimensions matter.
- Cleaning width: controls coverage per pass.
- Squeegee width: must pass through doors and recover water across the scrubbed path.
- Overall width and length: affect storage, lifts, transport and turning.
Tank capacity controls stops, weight and handling
A larger solution tank reduces refill stops, while a larger recovery tank delays draining. It also adds mass and changes handling. Small tanks suit short routes and sites with nearby service sinks. Larger tanks are more useful when the machine must work farther from water and drainage.
Ask how tank capacity is measured, how much usable solution remains near empty, whether the recovery tank has a float shutoff, and whether both tanks can be cleaned without awkward lifting. Dirty-water tanks and suction paths need regular rinsing; access matters as much as litres.
Match battery runtime to one cleaning block
Published runtime is normally based on a stated battery, operating mode and floor condition. Brush load, vacuum power, water flow, slope, turns and battery age change the result. The planned route should fit inside the expected runtime with a practical reserve.
| Battery question | What to confirm |
|---|---|
| Battery chemistry and capacity | Voltage, ampere-hours, approved charger and BMS requirements |
| Working time | Mode, brush and vacuum settings used for the claim |
| Charging time | Time to full charge and whether opportunity charging is permitted |
| Replacement | Connector, dimensions, weight and approved battery specification |
Do not choose a replacement charger or battery from voltage alone. Connector pinout, charge profile, battery chemistry and control requirements must match.
Choose the brush or pad from the floor, not its colour
Smooth vinyl, coated floors, terrazzo, textured tile and unfinished concrete do not need the same tooling. Soil also matters: loose dust, food residue, tyre marks and oily deposits require different levels of agitation and chemistry.
| Floor or task | Typical approach | Confirm before use |
|---|---|---|
| Coated or sensitive floor | Softer brush or less aggressive pad | Finish maker’s cleaning limits and a test area |
| Routine tile or vinyl cleaning | General-purpose brush or pad | Soil, detergent and slip requirements |
| Textured tile or concrete | Brush able to reach surface texture | Surface wear and acceptable agitation |
| Polishing or restoration | Task-specific pad and machine speed | Pad rating, chemical system and finish condition |
Pad colours are widely used as a guide, but they are not a universal performance standard across every manufacturer. Confirm material, aggression, diameter, centre opening and drive interface. Replacement brushes and pad drivers that look similar may use different hubs and locking structures.
A scrubber is only useful if it recovers the water
Drying performance depends on the vacuum motor, squeegee shape, blade condition, hose sealing, floor flatness and machine adjustment. A strong scrub deck with poor recovery leaves extra work and creates a slip risk.
Inspect whether the squeegee follows the floor through turns, whether blades can be reversed, and how easily the suction hose can be cleared. Gum-rubber and polyurethane blades are both common starting points, but compound, hardness and chemical resistance vary by manufacturer. Select from the recovered liquid, floor texture and the blade maker’s material data. Dimensions and profile must match the assembly.
Compact and medium walk-behind scrubbers solve different routes
The Geararo XD12 and Geararo T2 show why one specification cannot decide the purchase.
| Published specification | XD12 | T2 |
|---|---|---|
| Cleaning capacity | 1,200 m²/h | 1,500 m²/h |
| Cleaning width | 430 mm | 330 mm |
| Solution / recovery tank | 5 L / 8 L | 18 L / 20 L |
| Working time | 60–75 min | About 100–120 min |
| Net weight / brush pressure | 18 kg machine weight | 22 kg brush pressure |
| Best starting point | Tight furnished spaces and short daily routes | Longer routes with fewer tank stops |
The XD12 has the wider published cleaning path, but its small tanks and light body place it in a compact-use case. The T2 has a narrower published path but larger tanks, longer runtime and stated brush pressure for medium-sized daily routes. Test the route rather than ranking them from one number.

Frequently asked questions
What size floor scrubber do I need?
Choose from cleanable area, route time, access width and turning space. The rear squeegee and complete machine must fit, not only the brush deck.
Is a wider scrubber always faster?
No. Width helps in open areas. In congested spaces, turning and edge work can remove the advantage.
How much battery runtime is enough?
Enough to complete one planned cleaning block with reserve for travel, turns and battery ageing. Confirm the operating mode behind the published figure.
Should I use a brush or a pad?
Use the floor finish, soil, machine speed and required agitation to decide. Test an inconspicuous area when the surface is sensitive.
Why does a scrubber leave water behind?
Common causes include worn or incorrectly adjusted blades, blocked hoses, poor seals, excessive turns, uneven floors or a vacuum-system fault.
Need help matching a scrubber to the site?
Send the floor area, access dimensions, surface types, cleaning schedule and available utilities. Geararo can compare the machine, tooling and routine replacement parts as one working configuration.
