Where do divorces come from and how to overcome them?
Stains are caused by three factors: excess moisture remains on the surface, dirt isn't removed by the cleaning machinery, and dissolved salts and surfactants dry to form a film. To keep your floor shiny, you need to simultaneously control the pressure, the mop path, and the composition of the cleaning solution. The secret is simple: remove particles from the surface, moisten them just enough to float them into the micropile, and remove any remaining moisture quickly so they don't have time to dry in place.

Modules: fiber, vibrating mop and lifting platform
The classic fiber module is microfiber with the right density and pile pattern. It acts as a "capillary trap": fine filaments envelop dirt and retain it if the mop is damp enough, but not dripping wet. For parquet and laminate floors, medium-density microfiber with a short pile provides better water control and minimizes the risk of grout lift. On textured tiles, a fluffier fiber performs better, as it can lift dust out of the grout.
A vibrating mop adds the "local friction" that microfiber lacks. Rapid vibrations create high shear forces, which remove films and dried-on stains without the use of harsh chemicals. Three parameters are important: amplitude, frequency, and actual pressure. If your device allows it, choose a mode with noticeable vibration and moderate pressure: on parquet floors, it's important not to force water into the joints, while on tile and stone, you can increase the pressure for speed.
The raised platform is a godsend for mixed carpets and rugs. It prevents unwanted wetness and allows the mop to pass over thresholds without spreading dirt between rooms. A key benefit is the mop's consistent moisture content: raising the platform during movement reduces evaporation and the risk of the edges drying before the center, causing streaking.
Clamp: How much is "just right"
Contact, not pressure, is essential. On parquet, the pressure should ensure a stable contact surface, but not push out a puddle in front of the mop. If adjusting manually, aim for a thin, damp streak that disappears within 10-20 seconds with proper ventilation. On tile and porcelain stoneware, a higher pressure is acceptable: this allows the vibration module to better "open" dried stains, and the microfiber to penetrate deeper into the grout. On natural stone without factory impregnation, we again return to a gentler approach: less pressure and a longer curing time for the grout.
Trajectories: How to "Draw" Purity
Straight, parallel passes with half overlapping strokes are the most reliable, as each strip receives two mop passes and even moisture removal. A serpentine pattern is convenient in living rooms: the figure-eight motion reduces the risk of leaving diagonal streaks if the edge of the strip dries out. In the kitchen and hallway, a combined approach works well: first, a quick longitudinal pass to remove the main dirt, then a transverse "control" pass to collect residual surfactants and smooth out traces. It's important to avoid narrow "turning" curves, as this is where crescent-shaped streaks most often appear due to localized overdrying of the mop edge.
Chemistry: Safe formulations for various coatings
Parquet and oiled wood floors prefer a neutral pH. Gentle cleaners based on non-ionic surfactants and glycols labeled for wood floors are ideal here. They dissolve household dirt and film without stripping away protective oils or loosening the varnish. Water should preferably be low in minerals: if your tap water is hard, a drop of distilled water in the tank reduces the risk of salt stains.
Laminate flooring tolerates neutral and slightly alkaline cleaners, but does not tolerate over-wetting. It's better to let the cleaner sit on the stain for a few minutes than to try to scrape it off with force on the first pass. Porcelain and glazed tiles respond well to mildly alkaline kitchen and floor cleaners—they effectively remove grease stains. Mild acid cleaners are effective on limescale deposits and water stains, but avoid using acids on marble and travertine; a neutral cleaner with chelators and a dwell time will work best.
If you need a quick result without noticeable surfactant residue, a small amount of alcohol additives is useful—they speed up evaporation and reduce the chance of halos. The key is to avoid overdoing it, as this can dry out the wood and leave a "mirror-like" finish on matte stones.
Risk-free parquet: water under control
Wood isn't afraid of moisture per se, but of its excess in the joints. The principle is this: first, dry prep to avoid disturbing the sand under the mop, then short, dampened passes along the grain, and finally, a light, slightly dry finish with the same mop, but with a lower flow rate. If your robotic mop has a selectable mode, use the "Y-pattern" or double pass and set the lowest flow rate, compensating for it with a slightly slower speed. Oil-based floors benefit from neutral "no-rinse" products and regular re-application of the sealant: this reduces dirt adhesion and reduces streaking.
Dried stains on tiles: strength and micromechanics
Dried sauce, coffee stains, or household limescale are removed not by speed, but by patience. Wet the area, let the solution work for 2-3 minutes, then turn on the vibration or use a thicker fiber mop. If the tiles are textured, move perpendicular to the surface's texture so the mop fits into the micro-grooves. After removing the stain, be sure to rinse it off with clean water or a fresh portion of the solution with minimal surfactants; otherwise, the area will dry out and become matte.
Water, temperature and drying
Warm, but not hot, water accelerates the dissolution of grease and evaporation, which helps prevent streaks. In rooms with poor ventilation, open the air vents beforehand: air movement reduces drying time and prevents salts from settling on the surface. On large areas, it's helpful to finish mopping with a semi-dry cloth, and ideally, have a second clean mop to absorb residual moisture from highly visible areas, such as the entryway or kitchen.
Textiles: Half the battle is in the rag
Even the correct trajectory is useless against clogged microfiber. Wash the sheets separately at 40–60°C, without fabric softeners, as they clog the pile and cause streaks. Use a low-foaming detergent and a generous rinse. After cleaning, the mop should dry smoothly, not in a ball, otherwise a greasy area will always remain at the edge, which will then create a light arc on the floor.
What to consider when setting up robots
If the robot allows you to adjust the water flow and vibration intensity, choose the combination based on the surface: less water and medium vibration for parquet, standard water and increased vibration for tile, neutral detergents in the tank, and an occasional "rinse" pass with clean water. Dual-path algorithms with a platform lift through carpets reduce dirt transfer and streaks in doorways. An important detail is the mid-cycle rinsing of the mop. Even one quick "pit stop" at the base ensures more even drying and fewer marks on glossy surfaces.
Result: a balance of three factors
Streaks are achieved when three things come together: a mop that effectively picks up dirt, a cleaning path that evenly removes moisture, and cleaning agents that work with the material rather than against it. You control the pressure, create the right paths for the surfaces, and let the solution do its silent work. This will leave your parquet flooring feeling calm, and dried stains on the tiles will disappear without a trace.
