A scrubber dryer washes and lifts in one pass, which is what separates it from mopping. The brush works detergent into the floor and the squeegee and vacuum take the water back up behind it, so the floor is walkable immediately rather than left wet.
Scrubbing width sets how many passes a floor takes. The SD1260 covers 360mm and the SD1600 covers 450mm, and on a large open floor that difference compounds quickly. On a floor broken up by racking or machinery, the narrower machine gets into more of it, so width is chosen against the shape of the space rather than its size. Working capacity and machine weight are stated per body, running 18 to 34kg, which matters where the machine has to be lifted between floors.
Mains or battery is the second decision and it is about the trailing lead. A mains machine runs indefinitely but drags a cable that has to be managed round obstacles. A battery machine goes anywhere until it needs charging. Both the SD1260 and SD1600 are held in AC and BAT form, so the width can be chosen first and the power source second.
Steam cleaning is the other approach on this leaf. A 2000W steam cleaner with a 1.8L tank cleans with heat rather than detergent, which suits food areas and anywhere chemical residue is a problem. A 300mm water blade and hand cleaning items finish edges the machine cannot reach. Questions go over WhatsApp on 07754288583 with the floor area. Multipurpose wipes and a sink plunger sit on the leaf for the small jobs around the same work.
