How much floor can a scrubber dryer clean per hour?

Coverage depends on machine size: a small walk-behind (40-50cm) covers around 800 m²/hr, a large walk-behind (55-70cm) covers 1,500 m²/hr, and a ride-on (70-100cm) covers up to 3,000 m²/hr. Actual productivity may be 60-80% of these rates due to obstacles, turns, and refilling.

How much water does a scrubber dryer use?

Water usage ranges from 40-60ml per m² depending on machine type and solution flow setting. A large walk-behind cleaning 1,000 m² would use around 50 litres of solution. Always use the minimum water necessary for effective cleaning to reduce drying time.

How often do I need to refill the tank?

This depends on the tank size and floor area. A 50-litre tank walk-behind cleaning at 50ml/m² covers roughly 1,000 m² per fill. Plan your route to finish near a water source for refilling. Recovery tanks fill faster in heavily soiled areas.

What dilution ratio should I use in a scrubber dryer?

Follow the chemical manufacturer recommendation — common ratios are 1:50 to 1:100 for maintenance cleaning and 1:20 to 1:40 for heavy soiling. Using too much chemical wastes money, leaves residue on the floor, and can cause foam build-up in the recovery tank.

How We Calculate This

How the calculation works

This calculator estimates cleaning time, water usage and chemical consumption based on machine type and floor area.

Coverage rates (m² per hour)

Walk-behind small: 800 m²/hr (60ml/m² water)
Walk-behind large: 1,500 m²/hr (50ml/m² water)
Ride-on: 3,000 m²/hr (40ml/m² water)

Formulae

Cleaning time = (area ÷ coverage rate) × 60 mins

Total water = area × water usage per m²

Chemical = total water ÷ (dilution ratio + 1)

Tank refills = total water ÷ tank capacity
