A pivoting cover and removable brush roll let users clear tangled debris, inspect the agitator, and swap rollers without disassembly.

Flexible nozzle flaps open and close with stroke direction to guide debris, preserve suction, and clean uneven floors more completely.

Smooth curved airflow and a two-section funnel structure help this low-profile vacuum nozzle avoid clogging and preserve suction under furniture.

A lateral pivot and sealed elbow layout keeps the cleaner head maneuverable while reducing air leakage, turbulence, and noise.

A ratchet-and-pawl lock stops cleaner head droop when lifted, while allowing floor contact rotation and overload protection.

Hair-blocking ribs and a labyrinth end cap stop debris from reaching agitator bearings, preserving smooth rotation and cleaning performance.

Tilted jets and central suction form a bounded vortex that lifts dust without contact, reducing surface wear while improving heat transfer.

Multiple airflow passages in open struts keep suction working during blockages while cutting back pressure, weight, and housing material.

A peripheral drain trough and suction channel improve floor fluid pickup while avoiding the sticking that makes suction heads hard to move.

A gravity-retained detachable cleaning unit enables one-handed removal, stable mounting, and flexible handheld or upright vacuum use.

A hollow brush roller channels air through side openings to boost dust mobilization and cleaning efficiency without added fans or energy.

Mounting the support on the nozzle enables upright self-standing with a shorter, wheeled support that reduces bulk and floor scratching.

A spring-loaded adjustable blade assembly keeps a surface cleaning nozzle in contact with uneven floors while allowing height adjustment and storage.

A graded top surface, drains, and a recessed suction port help collect fluids above and below the aspirator while reducing operating room noise.

A suction-tube-actuated pushbutton adjusts brush height from the operator level, avoiding complex electronics and tube slippage.

PWM brush speed control keeps the agitator running at lower speed on hard floors, reducing debris scatter without losing cleaning effectiveness.

Pluggable support elements stabilize the suction nozzle during attachment, keeping the seal engaged and preventing leaks in hard-surface cleaners.

A rotatable subsidiary brush ahead of the drum brush loosens hair and fur from carpets while maintaining cleaning on irregular surfaces.

A movable bouncing element lets a rotating floor nozzle lift dirt and liquid in both forward and backward strokes without external vacuum.

A ramped clutch disk and torsion spring detect brush roller overload and trigger motor shutdown with low wear and better stability.

A rotatable base switches between hard and soft floor cleaning sides without valves, reducing rotation force, wear, and suction loss.

A flat suction-head base plate improves surface adherence, cuts suction losses, and keeps cleaning efficiency high on carpets and hard floors.

A shaped nozzle sole balances carpet penetration, airflow, and friction to lift embedded dirt with less pushing effort.

Compressed air dislodges dust while the vacuum captures it, enabling touch-free cleaning around small items and in tight spaces.

A fully flat suction head base plate improves surface adherence, cuts suction losses, and supports proper velvet strip alignment.
