Buying Guide: Key Purchase Considerations
- Floor type and space: choose width and tank capacity that match your facility size and floor hardness. Larger tanks reduce refills in big spaces.
- Cleaning workflow: decide between 3-in-1 wash-scrub-dry or a dedicated scrubbing plus drying approach based on downtime tolerance.
- Tank configuration: dual tanks (clean/recovery) support longer sessions; single-tank models may require more frequent refills.
- Power and portability: corded models provide consistent power but limit reach; battery-powered options improve mobility in large, corded-free areas.
- Noise and surface care: look for low-noise operation for offices and healthcare; check squeegee width for effective water pickup on varied floor types.
- Maintenance and setup: tool-free assembly and readily available replacement parts can reduce downtime and training time for staff.
