Abstract: A vacuum cleaner device comprises a main body, a brush device, and a vacuum driven motor. The main body has a primary vacuum inlet, a secondary vacuum inlet, and a vacuum outlet. The secondary vacuum inlet is operatively connected to the vacuum outlet. The brush device is configured and adapted to reciprocate relative to the main body. The vacuum driven motor is adapted and configured to be rotationally driven by air passing through the secondary vacuum inlet to the vacuum outlet. The vacuum driven motor is operatively connected to the brush device in a manner such that rotation of vacuum driven motor causes the brush device to reciprocate relative to the main body.

Abstract: A self-service kiosk enables customers to conduct rental transactions for carpet cleaning machines without the need of assistance from store personnel. The kiosk comprises a housing having several stalls or bays that hold and display carpet cleaning machines and carpet cleaning accessories for rental. The kiosk controls whether such carpet cleaning machines and carpet cleaning accessories can be removed from or returned to the kiosk. The kiosk also optionally includes a control panel for conducting a rental transaction. The self-service kiosk may also include automatic dispensing of cleaning products purchased by the customer at the kiosk. Still further, the self-serve kiosk may include shelving for holding cleaning products that can be purchased separately at a checkout counter.

Abstract: A floor cleaning machine has a housing and a movable hood that covers over vacuum and liquid hoses of the machine that are visible in prior art floor cleaning machines. The vacuum and liquid hoses are each pivotally connected to a wall of the machine housing and are also pivotally connected to a transparent dome provided on the hood. These connections reduce stresses on the hoses when the hood is moved and allow the dome to pivot relative to the hood. The floor cleaning machine also has a pair of slit orifices that eject fan spray patterns of cleaning liquid that are non-coplanar and do not intersect each other. Furthermore, the floor cleaning machine has an oscillating brush assembly that includes a brush that is replaceable without using tools. The brush height can be adjusted via an adjustment member provided on the oscillating portion of the assembly.

Abstract: A multiple function, modular vacuum cleaning system is described having a vacuum head which is releasably mounted on a waste recovery tank to form a first, portable wet/dry vacuum cleaning machine. The wet/dry vacuum cleaning machine in turn can be mounted on a cleaning solution tank to provide a second portable machine having wet extraction as well as wet and dry vacuum capabilities.

Abstract: A self-contained portable vacuum cleaning machine provides vacuum, hydro-extraction and pressure washing capability and incorporates a vacuum blower head which contains two blowers and (1) is adapted for serial or parallel vacuum blower operation and (2) incorporates a double wall construction which provides cooling air flow for the vacuum motors and defines an exhaust channel for the vacuum blowers which suppresses exhaust noise.

Abstract: A compact, self-contained central vacuum cleaning machine has expandable vacuum suction and pressure capacities and variable vacuum suction. The machine performs a multiplicity of cleaning operations including dry vacuuming, wet vacuuming, hydro-extraction vacuuming and pressure washing.
