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.

A vacuum cleaner includes a canister defining a debris chamber, a powerhead connected to a top of the canister, a hose, and a hose retainer removably connected to the canister. The canister includes a base and at least one sidewall extending therefrom. The powerhead includes a suction unit operable to generate airflow through the canister. The hose retainer includes a back plate defining an aperture therethrough, at least one hose retention clip defining a channel shaped and sized to receive the hose therein, and a dustpan defining a debris intake opening and including a hose end mount. When an inlet end of the hose is connected to the hose end mount, the inlet end of the hose is connected in fluid communication with the debris intake opening to generate airflow therethrough.

A touchless cleaning assembly for cleaning a room in a touch-less manner includes a cabinet is recessed into a wall of a room. A plurality of hose reels is positioned in the cabinet and each of the hose reels includes a hose that is drawable outwardly from the cabinet for spraying a fluid for cleaning surfaces in the room, for blowing air to dry the surfaces and to vacuum the surfaces. An air compressor is positioned within the cabinet to direct compressed air into a respective hose reel to dry the surfaces. A vacuum is positioned within the cabinet to supply vacuum pressure to the a respective hose reel for suctionally removing the fluid from a floor of the room.

Assemblies and method to extract a material from a material source may include a vacuum and material collector assembly to enhance extraction of the material from the material source. The vacuum and material collector assembly may include a material collector comprising a high volume pressure vessel having an interior and a high-pressure vacuum source pneumatically coupled to the pressure vessel. The vacuum source is operable to generate a high-pressure vacuum of a fluid flow through the interior of the pressure vessel to extract the waste material from the waste material source into the interior of the pressure vessel. The vacuum source may be connected to the pressure vessel of the material collector to form a unified vacuum and material collector assembly which may be supported on a single mobile chassis.

Embodiments of a unified airflow system for ultraviolet disinfection devices are disclosed. One embodiment of the present disclosure includes a unified airflow assembly and a control unit. The unified airflow assembly provides a shared airflow passage between a UV source and an airflow accessory capable of extracting contaminants from a target surface using a suction airstream. The UV source may be fluidically disconnected from the airflow accessory. The unified airflow assembly may include at least one air restriction unit in the shared airflow passage for manipulating a suction airstream therein. The control unit may be configured to drive the at least one air restriction unit to restrict the suction airstream to only one of the UV source and the airflow accessory.
