摘要:
A water re-fill unit for use with a reservoir of water, comprising: a water tank; a water inlet on said tank; and a water outlet on said tank for connection to said reservoir of water, wherein the water inlet is adapted to receive water from the reservoir of water and wherein the unit comprises a stand-alone system adapted to recycle at least 50% of the water intake from said reservoir of water using at least one water filtration means. Also provided is an adaptor for connection to a water conductor, the adaptor being suitable for location in a water reservoir to facilitate water intake therefrom, wherein the adaptor is heavy to facilitate sinking to a bed of the water reservoir and comprises a filtration member through which water intake is effected and a connector for attachment to the water conductor.

The present invention provides for an applicator pad which in some embodiments comprises filter material. In some embodiments, the filter material is air filter material, and has certain wet and/or dry friction characteristics, density, thickness, compressive resistance, liquid absorptive capacity, porosity, spreading capability, and / or leveling capability. In some embodiments, the pad has a stepped or otherwise uneven height ( Figure 7 ).
摘要:
The present invention refers to a surface-cleaning machine with on-board operator, such as a floor washing-drying machine, a floor washing machine, a sweeper, a high-pressure cleaner, a vacuum cleaner, or similar machines, provided with an operators compartment (10) including a footboard (30) that defines a first fixed reference surface (31), having adjacent to it at least one pedal (40) to control the surface cleaning machine, wherein said footboard (30) comprises at least one resting member (50) defining a second resting surface (51), with said second resting surface (51) being adjustable with respect to said first fixed reference surface (31).
摘要:
Mobile cleaning equipment comprising a powered wheeled vehicle (50) with an integral driver's cab (51) containing vehicle drive controls and a water supply tank (52) carried by the vehicle (50). The vehicle (50) also has a ground- or floor- engageable cleaning head (88) having, outlet jets and also a peripheral suction channel. A powered pressure pump (60) connected between the water supply tank (52) and the outlet jets of the cleaning head (88), and a rotary suction device (84) is connected between the suction inlets and the water supply tank (52). The mobile cleaning equipment also comprises at least one filter (85, 74, & 75) arranged between the water supply tank (52) and said powered pressure pump (60).
摘要:
A rider surface maintenance vehicle with variable dynamic braking, in contrast to a mechanically-engaged braking system that uses a brake cable. A brake pedal engages a sensor that encodes the pedal position as an electronic signal. The electronic signal, along with the vehicle velocity, determines a machine deceleration rate, or braking rate, either by calculation, lookup table, or a combination of the two. The braking rate may be tuned so that the of the brake mimics or approximates the feel of a conventional mechanically-engaged brake that uses a brake cable. During stopping, once the vehicle passes below a threshold velocity, a parking brake is automatically engaged. The braking rate is converted to a duty cycle, and the braking is preferably accomplished by pulse width modulation (PWM) of an electrical load applied in parallel to the motor.
摘要:
An autonomous floor cleaning robot (100) includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis (200) carries a first cleaning zone (600) comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements (700) arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid (S) and a waste container (D) for storing waste materials collected up from the cleaning surface.
