Carpet Cleaners TRIZ Cases

A docking evacuation station uses external vacuum suction to empty a robot cleaner bin automatically, extending runtime and area coverage.

A spiral-track telescopic handle rotates the mop head in the bucket, reducing bending and time spent wetting and wringing.

A screw drive clutch turns push-pull handle motion into mop-head spin, reducing user force while improving water wringing.

Water-soluble fibrous elements combined with active agent particles enable controlled release while preserving structural stability in use.

Aerosol or compressed-gas powder dispensing cleans carpet spots effectively while avoiding residual moisture, shrinkage, and long drying time.

A removable nozzle and fluid distributor module improves stain treatment and simplifies maintenance in extraction carpet cleaners.

A detachable scrubber head and thumb pump combine long-handle back reach with hand-held washing, scrubbing, massage, and exfoliation.

Laser welding bonds the drive disc coating without glue, preventing moisture ingress, detachment, and germ nests in floor cleaning machines.

A forced-air collection manifold uses adjustable panels and a perforated bag to channel debris into one receptacle while letting air escape.

A flexible squeegee and removable microfiber bonnet combine drying and polishing in one tool while simplifying washing and part replacement.

Residual moisture sensing in the mop plate replaces unreliable pH and visual checks to signal when a mop cover should be changed.

Sliding wringer arms with cam surfaces apply uniform progressive pressure to remove wash liquid efficiently while preserving mop mobility.

Multiple brushrolls and brush assemblies rotating on different axes improve fluid agitation, dirt removal, and sweeper-track appearance in fewer passes.

Curved concave-convex blades channel liquid toward suction ports, improving floor pickup efficiency and simplifying blade replacement.

A pivoting manifold keeps steam directed to either side of a reversible mop pad, reducing pad changes and supporting continuous cleaning.

An abrasive body bonded to a cleaning strip hangs lower for broader floor contact, improving removal of stubborn dirt without strip blockage.

A floating internal thread lets a steam applicator rotate without loosening the conduit connection, preventing disengagement and steam loss.

Integrated rinsing lines spray the dirty liquid tank interior to remove residue faster and make post-use floor cleaner cleanup easier.

A blade-shaped marking insert fits a utility knife to draw thin, accurate lines on rough surfaces without sharpening.

An interlocking squeegee-style closure seals the receptacle opening to prevent liquid, semi-liquid, and dry waste from escaping during transport.

Helicoidal drive surfaces create axial clamping only during rotation, removing brush play, vibration, and long-term creep.

A movable running wheel disengages the rotary brush for tool-free replacement while still holding and driving it securely during sweeping.

A rigid cuff with a direction-reversing transition blocks aqueous scrub solutions from running down the arm during overhead cleaning.

Guide sections on the brush disk engage flange mating sections to correct tolerance misalignment, cut noise, and prevent fastening damage.

An abrasive body bonded to hanging cleaning strips increases floor contact area, helping mop heads remove firmly adhering dirt more effectively.

A foot-pedal lever releases the latched disc cleaning tool axially, enabling tool-free replacement without tilting the floor machine.

Hydrophilic nonwoven layers combined with fiber bundles improve liquid absorbency, dust pickup, and low-residue cleaning on glass, wood, and other surfaces.

Hydrophilic nonwoven layers and an absorbent pad structure trap dust, limit redeposition, and spread polishing solution evenly on surfaces.

Curved concave-convex squeegee blades channel floor liquid toward suction ports, improving pickup with less suction and easier blade replacement.

Direct liquid application beneath a sheet mop improves removal of tough dirt and dust while preserving easy wet or dry cleaning.

Multiple blade and rear support contact points keep the edge flush to the floor, preventing debris from slipping underneath.

A retractable screw bit nested in the putty knife handle cuts tool switching, saves belt space, and improves screwing leverage in drywall work.

A compliant evacuation connector and portable vacuum let a robotic cleaner empty debris autonomously, extending runtime and coverage.

A removable steam module, diverter valve, and auxiliary hose let one cleaner switch from floors to above-floor surfaces without chemicals.

Calibration values from empty-drum and phase-shift measurements correct spin-sensor errors for more accurate washing drum imbalance detection.

A removable nozzle and spray unit improves stain treatment and simplifies access to fluid delivery and recovery parts for maintenance.

Large stems loosen embedded hair while dense small stems capture it, enabling non-adhesive cleaning across fabric and carpet.

Amphiphilic surfactants give cleaning pad fibers both hydrophilic and hydrophobic character, improving dust pick-up and retention.

A diverter valve and auxiliary hose route steam to either the mop foot or hand tool, enabling chemical-free floor and above-floor cleaning.

A vented soak-and-compress sponge steriliser absorbs disinfectant, then dispenses it safely to kill bacteria and fungi without microwave fire risk.

Two clip-connected half-shells form a stiff hollow roller with drainage slots, improving sponge board wiping and cement residue removal.

A tilting joint shifts toward the active cleaning surface to balance pressure, reduce user effort, and prevent instability during floor cleaning.

Embedded abrasive particles help melamine foam remove greasy soap scum and kitchen dirt while improving durability and surface safety.

A tapered press attachment with a scraper edge lets round fringed mop heads enter smoothly, wring out effectively, and drain in a compact bucket.

An air-venting valve equalizes suction cup pressure fast, letting a glass-wiping robot detach immediately and improve work efficiency.

Steam boosts a peroxygen-surfactant cleaning composition to oxidize and lift stubborn floor stains for complete removal without reoccurrence.

A floor cleaner uses a 180° pivoting head and brush-driven travel assist to cut user effort while reaching corners and wall edges.

An inner bar nested inside the scooter grip keeps hands within a protective frame, reducing impact injury during maneuvering.

Offset drivers and an eccentric cleaning plate cut vertical oscillation, lowering energy use while improving surface cleaning and pad absorption.

A load-activated brake locks the mopping chassis during wringing or bucket loading, preventing roll-away without extra controls.
