Vacuum cleaners to be mounted in a vehicle are disclosed. Some of the vacuum cleaners have a modular design that allow the vacuum cleaners to be arranged, assembled, and/or installed in different configurations and to fit in different spaces within the vehicle. Vacuum cleaners may include a vacuum module, a collector module, and/or a hose storage module. An interconnecting duct is configured to operatively couple the vacuum module and the collector module in any one of a plurality of different predefined assembly configurations. The collector module may have a debris canister that may be lifted straight out of a collector housing. The vacuum cleaner may be installed in a vehicle in a manner to allow easy removal of the debris canister without disconnecting and/or removing other portions of the vacuum cleaner.

A vehicle vacuuming system that includes: a vacuum housing having an air filter, a motor within the interior volume of the vacuum housing wherein the motor supplies air suction power to a vacuum air intake distal from the motor and through a vacuum hose operably engaged with the vacuum housing, and an air outlet proximate the motor; and a pressure notification system chosen from the group consisting of a light, a speaker, a mobile application, and combinations thereof operably connected to a pressure sensing system associated with the vehicle vacuuming system.

A vehicle floor mat vacuum machine includes an elongate open mouth communicating with an interior chamber for passage of a floor mat therethrough and between an upper feed roller and a lower brush roller for contacting a carpet surface of the floor mat. A vacuum source connects to a vacuum manifold to create suction, as the brush roller and suction force work in conjunction to remove sand, dirt and other debris from the floor mat. An electric motor, drive belt and reduction gear assembly rotate the feed roller and brush roller in opposite directions with the brush roller rotating at a significantly higher speed. In one embodiment, the vacuum source is a central vacuum system, wherein a solenoid-controlled valve in the vacuum line extending from the feed roller is opened for a timed sequence during operation of the machine.

A central vacuum system with several suction hoses provided with a suction nozzle which, after having vacuumed with the suction hose concerned, must be placed in a suction nozzle holder and which, before vacuuming with the suction hose concerned, must be taken out of the suction nozzle holder. The central vacuum system includes a detection system for detecting whether a suction nozzle is either or not placed in its corresponding suction nozzle holder, as well as a control unit which is connected to the detection system. The control unit controls the suction force of the central pump installation as a function of the number of suction hoses being used.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

A cleaner system for an MRI magnet room. The system includes a base vacuum and/r steam unit configured to supply vacuum and/or steam, the unit disposed outside the MRI magnet room. A hand-held or portable dispensing unit is substantially free of magnetic material so that it is safe to use inside the magnet room. A tubing system for conveying vacuum and/or steam from the base unit to the handheld unit, the tubing system including a magnet room portion configured for disposition inside the magnet room and free of magnetic material. A communication link is configured to communicate control signals generated by user manipulation of a control panel to the base unit.

A vacuum producing suction and air blowing simultaneously at a same surface of the device, is disclosed here in. A pump and compressor work simultaneously to both blow and suck air through a dual-line hose. A pressure gradient is created between the surface of the device and a surface being cleaned, due to high pressure being created by the air blowing, and low pressure being created by the air sucking. This causes dust, dirt, and the like to be pulled from the surface being cleaned and sucked in a suction portal, and into a suction line of the dual-line hose. This can be accomplished with a central vacuum system or standalone vacuum.
