Disclosed are devices, systems, and methods for modular vacuum cleaners. An example vacuum cleaner system includes a canister vacuum cleaner device and a robotic vacuum cleaner device, where the robotic vacuum cleaner is removably coupled to or is digitally communicable with the canister vacuum cleaner device. The canister vacuum cleaner device comprises a canister to collect debris, a vertical hollow structure that located towards a rear of the canister and coupled to the canister, a flexible extendable hose, and a housing located below the canister, wherein the housing includes a retractable electrical cord. The robotic vacuum cleaner device comprises: a storage area to collect debris, a battery, a plurality of wheels that are removably coupled to one or more motors, and a lever or a valve structured to direct debris either to the storage area or to the canister.

The gate housing has a flow passage therethrough, the flow passage having an inlet and an outlet. The gate housing also includes a gate pocket configured to receive a blast gate and to allow the blast gate to slide therein between an open position and a closed position. The magnetic brake element is on the gate housing and includes a magnet mounted to the gate housing such that a magnetic force of the magnet extends into the gate pocket.

A ferromagnetic material sequestering device for separating metals from a waste stream generated by a vacuum includes a shell, which has a bottom and a top. The bottom is open and a hole is positioned in the shell proximate to the top. A connector is engaged to the shell proximate to the hole engages a hose that is operationally engaged to a vacuum generator so that the vacuum generator is in fluidic communication with the shell. The vacuum generator is positioned to suction a mixture of objects through the shell. A magnet is engaged to the shell and magnetically engages ferromagnetic materials in the mixture of objects. The ferromagnetic materials thus are sequestered within the shell and can be reclaimed.

A vacuum cleaner is disclosed. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a main housing and a driver. The driver includes a motor and a transmission. The motor is provided behind a rotating brush. The transmission transfers rotational motion of the motor to the rotating brush.

A dust collection system for a power tool can collect, with an ordinary bit, dust with a flexible hose connected. A dust collection system for a power tool includes a power tool to receive a tip tool protruding frontward and including a tool body, a cylindrical first dust collection attachment attachable to the tool body and covering the tip tool over its entire circumference with the first dust collection attachment being attached, a second dust collection attachment attachable to the tool body and including a dust collector, and a flexible hose to connect the first dust collection attachment and the second dust collection attachment to collect dust sucked through the first dust collection attachment into the dust collector included in the second dust collection attachment.

A wand includes a hinge configured to pivotally connect first and second wand segments in an extended configuration and a storage configuration. A first locking mechanism locks the wand in extended configuration. A second locking mechanism includes a rod, a sliding lever, a plunger, and a plunger cavity. The plunger is configured to be received in the plunger cavity to lock the wand in the storage configuration. When in the extended configuration, depressing a single actuator pivots the locking arm, causes the hook/pawl to be removed from the locking cavity, and unlocks the wand. When in the storage configuration, depressing the single actuator causes the rod to move in a first direction, causes the sliding rod to move a second direction, and urges the plunger out of the plunger cavity.

The present disclosure relates to a wrap element for attaching to a cleaning device. The wrap element may include a sheet of barrier material. The sheet may include first and second edges extending along the sheet in a longitudinal direction. Third and fourth edges may extend along the sheet in a direction orthogonal to the first and second edges. A folded over portion may extend in the longitudinal direction along a majority of the first edge. Fasteners may be disposed on the sheet, such as nearer the third edge than the fourth edge and may extend in the direction orthogonal to the first edge along a majority of the third edge. The fasteners may allow the sheet of barrier material to removably connect to itself. A fit indicator may extend in the longitudinal direction along a majority of the first edge.

An industrial robotic vacuum system for cleaning agricultural facility ventilation ductwork. The industrial robotic vacuum system generally includes a robotic vacuum head.

A vacuum cleaner assembly includes a vacuum body, a suction wand removably connected to the vacuum body, and an accessory removably connected to the suction wand. A suction motor is disposed in the vacuum body and is configured to create flow through a suction path. An accessory motor is disposed in the accessory. A first power source is configured to supply power to the suction motor and to the accessory motor. A second power source is configured to supply power to the suction motor and to the accessory motor when the first power source falls below a predetermined charge level.
