An elongate dirt container redirects cyclone airflow to keep separated dust from re-entering the vortex, extending filter cleaning intervals.

A recessed cyclone and domed rolling assembly keep the vacuum upright, prevent side-tip sticking, and allow easier dirt emptying.

A gravity-held storage mount lowers and shifts the cleaning unit forward to prevent vacuum tip-over without added locks.

Validated differential-pressure sensing filters blower and nozzle interference to keep vacuum bag fill indication accurate and detect blockages.

Multiple cyclone paths and fine dust filters maintain suction, cut discharge noise, and improve fine dust removal in a robot cleaner.

A porous mesh and fiber composite keeps vacuum filter bags stable and weldable without sacrificing air permeability or clogging resistance.

A nested two-stage cyclone layout shortens airflow paths, cuts energy loss, and lets vacuum cleaners empty separated dirt in one container.

A rotatable handle with fixing protrusions and an elastic member stabilizes dust box release while preventing impurity or water leakage.

A controlled lid actuator lets a removable cyclone dust container empty with less dust swirl and less contact with dusty surfaces.

By placing the suction source and cable reel below the dust bag compartment, this layout improves stability without sacrificing bag fill.

Multiple flow openings with resistance-matched cross-sections help a vacuum dust collector maintain suction as filters clog while reducing turbulence.

A shaped filter bag chamber lets non-woven vacuum bags expand freely for more even filling, better dust use, and longer bag life.

A releasable cyclone separator compresses collected dust inside the container, extending emptying intervals without added compression hardware.

A helical hood sends air and debris downward in a spiral to keep bag pores clear, maintain airflow, and let leaf vacuum bags fill fully.

A threaded inner-to-outer filter fit lets the full vacuum cleaner filter assembly be removed securely by gripping the inner filter top.

An angled stop stabilizes a pivoting dust-extractor flap to block dust backflow under pressure reversals in handheld power tools.

A rotatable cuff and diffuser let the blower vacuum bag shift position to limit moisture leakage, user wetting, and bag wall wear.

A spiral flow guide and direct inlet layout keep cyclone airflow aligned, cutting pressure loss and improving dust separation in hand-held cleaners.

A thick upstream coarse layer traps brick and plaster dust before the fine filter, extending suction and reducing fouling.

An inclined dust bag collar cuts flap pivot energy, speeds sealing, and reduces dust or activated carbon leakage without hurting airflow.

Rounded cyclone inlet transitions and vortex finder placement cut turbulence and back pressure, improving vacuum cleaning efficiency and noise control.

A collar inside the vacuum cleaner filter bag blocks filter cake from the closure device, preserving usable filter area and plate stability.

Minimal welded multilayer nonwoven construction lowers bulk density and raises vacuum cleaner filter bag dust capacity without sacrificing strength.

A conical diffuser with elongated openings swirls inlet airflow to spread dust, prevent clogging, and extend vacuum bag service life.

Dual dirt outlets in a cyclonic hand vacuum keep discharge paths open when tilted, improving capacity and maintaining airflow.

A larger chamber-opening-to-bag area ratio lets a flat vacuum filter bag stay unfolded, preserving dust capacity and filtration efficiency.

Multiple tangential cyclone inlets cut flow resistance, helping compact vacuum cleaners raise suction or lower noise and power use.

A uniflow cyclone with a sidewall outlet cuts entrained dust reaching the pre-motor filter, improving separation and reducing wash frequency.

A spring-loaded main switch uses torque-triggered mechanical tripping to shut down an overloaded brush vacuum drive without extra electronics.

A spring-loaded torque trigger shuts off the brush vacuum drive during overload, improving protection without added electronic control complexity.

A movable receptacle and sealed attachment maintain suction for efficient kitchen waste pickup without complex central vacuum installation.

Motor current and power from the fan and nozzle are used to track dust bin filling accurately across different floor coverings.

A modular cart-mounted vacuum uses staged filtration and separable modules to capture dust, cut noise, and reduce cross-contamination.

Cyclone separation lets steam cleaning and suction run together while draining liquid away so the debris chamber stays perceptibly dry.

Dual front and rear dirt outlets keep a cyclonic hand vacuum collecting debris when tilted, improving capacity and ease of emptying.

A sealed removable dirt chamber lets cyclonic hand vacuums be emptied and washed more easily while preventing dirt dispersal and motor damage.

Separating clean and dirty liquid containers lets users refill or empty only one side, reducing handling load in floor cleaners.

Longitudinal folds let an upright vacuum filter bag fully open on insertion, preventing kinks, preserving dust capacity, and extending service life.

A slide-out drum and filter assembly lets wet/dry vacuum debris be removed as one unit, reducing mess during emptying and filter cleaning.

An inclined parked suction head drains water back into the container, cutting drying time and reducing mildew and odor risk.

An inclined airflow path places the dust box between suction and cyclone units to expand capacity while preserving low robot height and suction efficiency.
