Surfaces and compatibility
For hard floors that permit machine scrubbing and water recovery. Identify the covering, finish, joints and level changes before choosing a brush or pad.
The 120 V / 60 Hz mains supply avoids charging but requires cord management. Listed theoretical and practical outputs differ; obstacles and stops add time.
Preparation and use
- Remove large loose debris and clear the route. Mark the work area.
- Inspect brushes, squeegee blades, filters, tanks and power supply.
- Fit approved consumables and dose a cleaner compatible with floor and machine.
- Test suitable settings. Monitor scrubbing and water recovery, particularly when turning.
- Empty the recovery tank before it overfills and inspect results after drying.
Care and storage
Rinse tanks and filters as instructed. Clear debris from blades and brushes and check wear. For battery models, follow the specified charger, ventilation and charging cycle. Inspect and store cords on mains models.
Limits and things to check
Cleaning width is not always overall width: measure the squeegee, turns and doorways too. Actual output includes filling, emptying, obstacles and travel. Water streaks call first for checking blades, hose and tank.
Equipment, accessories and options
Supplier-listed equipment: two rollers, transport wheels and suction tools. Check supplied rollers and options for porcelain tile or grout.
Practical questions
How do I check this reference suits my floor?
Identify flooring, finish and task, then check both product and flooring instructions. A hidden-area test should reproduce full application and drying. For equipment, also check tools or pads, dimensions and power supply.
Are all accessories and consumables included?
Supplier-listed equipment: two rollers, transport wheels and suction tools. Check supplied rollers and options for porcelain tile or grout.
What information is still needed before purchasing?
Confirm cord length, roller references and warranty terms.
Why might results differ from the listed output?
Figures describe different things: working path, theoretical or practical output, power and runtime by mode. Filling, emptying, charging, obstacles, consumable condition and technique influence actual work completed.
