Award-winning ergonomic floor cleaning machines designed for user comfort and to reduce operator fatigue.
At Hako, we’ve got your back!
Hako’s range of ergonomic floor cleaning machines has been independently recognised for promoting operator comfort and back health. Both selected ride-on and walk-behind Scrubmaster scrubber dryers have been awarded the prestigious AGR (Aktion Gesunder Rücken e.V.) quality label for their back-friendly overall machine concept.
Hako was the first manufacturer worldwide to receive this independent certification for its scrubber dryers, reinforcing its commitment to operator wellbeing and ergonomic machine design.

Why ergonomics matter
Back pain remains one of the most common workplace health issues within the commercial cleaning industry. Long hours of repetitive movements, confined work areas and physically demanding cleaning tasks can place considerable strain on operators.
By reducing unnecessary effort, supporting natural body movements and improving operator comfort, Hako’s ergonomic scrubber dryers help minimise fatigue, improve productivity and contribute to healthier workplaces.

Independently AGR certified
The AGR quality label is awarded by Aktion Gesunder Rücken e.V. (Campaign for Healthier Backs), an independent German organisation dedicated to promoting spinal health.
Products are evaluated by a panel of medical specialists, physiotherapists and ergonomics experts who assess how effectively they reduce stress on the spine and support the body’s natural movement. Only products meeting strict ergonomic criteria receive AGR certification.
Hako AGR-certified scrubber dryers include:
- Scrubmaster B35 (walk behind)
- Scrubmaster B50 (walk behind)
- Scrubmaster B75 i (autonomous / robot)
- Scrubmaster B400 R (ride on)
- Scrubmaster B75 R (ride on)
- Scrubmaster B120 R (ride on)
- Scrubmaster B175 R (ride on)
- Scrubmaster B260 R (ride on)
Ergonomically designed in every detail
Intuitive controls
A clearly arranged operating panel with an easy-to-read colour display and simple symbols reduces operator fatigue, minimises errors and makes every cleaning task easier. Eco mode also lowers noise levels, creating a quieter and more comfortable working environment.
Comfortable operation
The ergonomic steering wheel provides excellent visibility of the controls and is optionally available with a steering knob for effortless manoeuvring. Ride-on models feature adjustable suspension seats with adjustable armrests and backrests, allowing operators to tailor seating position for maximum comfort throughout the day.
Natural, controlled movement
Forward and reverse drive, adjustable working speeds and automatic speed reduction when cornering allow operators to work at a comfortable pace while maintaining excellent machine control. Stable three-wheel designs further improve manoeuvrability and reduce unnecessary physical effort.
Designed for every operator
Walk-behind Scrubmaster models feature angled operating handles and ergonomically positioned controls that encourage an upright working posture regardless of the operator’s height. This helps reduce bending, overreaching and shoulder strain during extended cleaning sessions.
Easy daily maintenance
Routine maintenance has also been designed with ergonomics in mind. Large tank openings, easily accessible filters and simple recovery tank emptying reduce unnecessary lifting and awkward movements. The patented automatic squeegee cleaning system and Quick-Connect squeegee design allow fast, tool-free maintenance.
Built to recognised ergonomic standards
The Scrubmaster B35 and B50 comply with the requirements of DIN EN 60335-2-72 and DIN EN 1005, demonstrating Hako’s commitment to internationally recognised ergonomic and safety standards.
