• Liquid which has been removed from the cleaning material by the wringing apparatus 199, or otherwise, or which has been dispensed from the fluid dispenser 189, but which has not contacted the cleaning material is collected by the liquid collection tray 196.
• the collected liquid is then returned to the reservoir 191 .
• said liquid may either be cleaned and returned to the tank 410 where it may be reused, or stored in the reservoir 191 until said reservoir is removed from the material cleaning apparatus 164 by the user and the waste liquid disposed of.
• the cleaning head is ejected from the body 170 of the material cleaning device 164 via the cleaning head aperture 420.
• the ejection of the cleaning head from the body 170 may again be assisted by the primary roller 430.
• the operation of the primary roller 430 may again be governed by the controller.
• the cleaning head may be ejected from the body 170 on to a collection tray (not shown).
• a collection tray locates the ejected cleaning head such that a user may easily obtain a cleaning head with cleaned mop material at the same time, or at a very similar time, to placing a cleaning head with soiled mop material into the mop material cleaning device.
• a cleaning head with cleaned cleaning material is provided to the user at the rear of the material cleaning device 164.
• the user is able to place a dirty cleaning head at the rear of the mop material cleaning device 164, and immediately obtain a cleaning head with clean mop material from the collection tray of the material cleaning device 164, thus removing the requirement for the user to wait whilst the material cleaning device 164 operates.
• the material cleaning device is mounted on wheels 173, 175.
• the wheels 173 at the rear of the material cleaning device 164 comprise rubber tyres
• the wheels 175 at the front of the material cleaning device 164 are mounted on castors such that they may rotate around an axis substantially normal to the surface on which the material cleaning device 164 is placed.
• the material cleaning device 164 may be moved on its wheels 173, 175 by a user via the use of a handle 172.
• Figures 5 and 5a provide a further schematic view of the material cleaning device 164 which illustrates the general layout of said device.
• the handle 172, body 170, wheels 173, 175, drawer 400, and tank 410 are all illustrated in addition to the depiction of an access panel 440 which provides the user with the ability to access the rollers inside the material cleaning device 164 in case of blockage, mechanical failure or routine maintenance. Additionally, in this view of this embodiment of the material cleaning device 164, the vessel 191 is removed from the material cleaning device 164 leaving a space where the vessel 191 may be inserted 450.
• Figure 6 schematically illustrates a further view of this embodiment of the material cleaning device.
• the additional feature of a storage recess 460 for an additional cleaning head or heads is depicted, as well as an emergency stop button 470 to be activated by the user of the material cleaning device 164 in case of any emergency situation.
