The cleaning head 12 comprises two cleaning pads 18, which are arranged to contact a floor and oscillate during use, and a front squeegee 20 and rear squeegee 22, respectively positioned in front of and behind the cleaning pads 18. The terms front and rear will be understood by the skilled person to mean the front and rear of the cleaning head 12 when the floor cleaner 10 is being used by a user. In FIG. 1, the front squeegee 20 is shown in a retracted position, and may also be folded down into a deployed position, in which the front squeegee 20 makes contact with the floor. The body 14 comprises a cleaning fluid reservoir, a waste fluid reservoir, and a battery (not shown). The cleaning fluid reservoir is arranged to hold cleaning fluid and apply the cleaning fluid to the floor during use of the floor cleaner 10. The cleaning pads 18 oscillate during use of the floor cleaner, thereby agitating the cleaning fluid on the floor, providing a cleaning effect. The cleaning fluid becomes dirty during agitation, and the waste liquid reservoir is arranged to suck up and store the waste liquid during use of the floor cleaner. The battery is arranged to power the application of cleaning fluid to the floor, the oscillation of the cleaning pads 20, and the sucking up of the waste liquid. The handle 16 comprises a user interface 24 which turns on and off the floor cleaner functions.

[0020] FIG. 2 shows the floor cleaner 10 which has been inserted into a mobile dock 30. The mobile dock 30 comprises a receiving unit 32 which receives the cleaning head 12 of the floor cleaner 10, and a support arm 34 against which the handle 16 of the floor cleaner 10 rests. The mobile dock 30 also comprises four driven wheels 36 (only three shown in FIG. 2) located at the corners of the mobile dock 30, which may be driven to effect translational motion of the mobile dock 30.

[0021] FIG. 3 shows the floor cleaner 10 and mobile dock 30 as described with reference to FIG. 2, with the floor cleaner 10 removed from the mobile dock 30 and being used to clean a floor by a user 38. The mobile dock 30 is arranged to move towards a paired device in the possession of the user 38 as will be described below.

[0022] FIG. 4 shows a schematic representation of the components of the mobile dock 30 and a paired device 56. The mobile dock 30 comprises a battery 40, a waste liquid reservoir 42, a cleaning fluid reservoir 44, cleaning jets 46, a receiving unit 32, a control unit 48, a wireless communications unit 50, a charging port 52, and a user interface 54. The battery 40 is attached to a charging cord which allows connection to mains power for recharging the battery 40. The battery 40 is further connected to and powers the driven wheels 36, each of which includes a small electric motor arranged to drive an attached wheel. The battery may also be connected to and supply power to the charging port 52. The charging port 52 is arranged to electrically connect to the floor cleaner 10 and supply an additional charge to the battery of the floor cleaner 10. In this embodiment, the charging port 52 provides a wireless charging function. In alternative arrangements, the charging port 52 may physically connect to the floor cleaner 10 in order to charge the battery of the floor cleaner 10. The waste liquid reservoir 42 is arranged to receive waste liquid from the waste liquid tank of the floor cleaner 10 when the floor cleaner 10 and the mobile dock 30 are joined together. The waste liquid reservoir 42 is arranged underneath the waste liquid tank of the floor cleaner 10, the waste liquid tank of the floor cleaner 10 further including a outlet port which is opened when the floor cleaner 10 is joined with the mobile dock 30, such that the waste liquid empties from the waste liquid tank of the floor cleaner into the waste liquid reservoir 42 under gravity. The cleaning fluid reservoir 44 includes a nozzle which connects to the cleaning fluid tank of the floor cleaner 10 when the floor cleaner 10 and mobile dock 30 are joined together. The cleaning fluid reservoir 44 is arranged to feed cleaning fluid through the nozzle into the cleaning fluid tank of the floor cleaner 10 in order to refill the floor cleaner 10. The cleaning jets 46 are arranged to squirt cleaning fluid onto the cleaning pads 18 of the floor cleaner 10 when the floor cleaner 10 and mobile dock are joined together. This agitates any dirt present on the cleaning pads 18, such that the dirt is removed from the cleaning pads 18. The receiving unit 32 has already been shown in FIG. 2, and is shaped and sized to approximately correspond to the shape and size of the cleaning head 12 of the floor cleaner 10. The control unit 48 is arranged to control all of the functions of the mobile dock 30, including the operation of the active functions such as refilling the cleaning fluid reservoir of the floor cleaner 10, the charging of the floor cleaner 10, and the cleaning of the cleaning pads 18. The control unit 48 is also connected to the wireless communications unit 50. The wireless communications unit 50 is arranged to wirelessly communicate with a paired device 56, which in this case is a smart device being carried by the user 38. In this embodiment, the wireless communications protocol is Bluetooth. Any suitable wireless communications protocol could be used.

[0023] The mobile dock is operable in either a follow-me mode, or a come-to-me mode.

[0024] In the follow-me mode, the wireless communications unit 50 is arranged to remain in regular communication with the paired device 56 in order to ascertain the location of the paired device 56, and send that information to the control unit 48 which controls the movement of the mobile dock 30 such that the mobile dock 30 remains a consistent distance from the paired device 56. The paired device 56 and the mobile dock 30 may each comprise a GPS chip in order to ascertain the relative positions of the paired device 56 and mobile dock 30. The skilled person will appreciate various other sensors may be used, for example optical, laser, ultrasound, and/or infrared, in order to determine the relative locations of the paired device 56 and mobile dock 30. As the user 38 operates the floor cleaning device 10, the mobile dock 30 follows the user 38 around to provide convenient access to the mobile dock 30 and the various services provided by the mobile dock 30. In the come-to-me mode, the user 38 activates the paired device 56 to send a signal to the wireless communications unit 50, that signal including the location of the paired device 56 and a command which is passed to the control unit 48 which activates the movement of the mobile dock 30 such that the mobile dock 30 moves into close proximity to the location of the paired device 56. The activation of the paired device 56 comprises selecting a come-to-me option provided via a user interface of the paired device 56. This allows the user 38 to conveniently access the mobile dock 30 when required. The mobile dock 30 is also operable in a home mode when the floor cleaner 10 is received by the mobile dock 30. In the home mode, the control unit 48 is arranged to activate movement of the mobile dock 30 such that the mobile dock 30 moves to a home location, for example in a utility cupboard. The mobile dock 30 may also automatically connect to a home station at the home location. The home station may comprise a charging point connected to mains electricity, and arranged to charge the battery 40. The home station may further include cleaning fluid and waste liquid reservoirs to respectively refill and empty the cleaning fluid reservoir 44 and waste liquid reservoir 42 of the mobile dock 30. Such an arrangement will further decrease the maintenance actions required to be undertaken by the user. The home mode may be activated by the user 38 operating the paired device 56. In alternative or additional arrangements, the home mode may be activated by a user interface present on the mobile dock 30, or after a set amount of time has elapsed since the floor cleaner 10 was received by the mobile dock 30. The set amount of time is chosen to correspond with the user 38 finishing their cleaning activities, for example 10 minutes. After the elapsed time, the home mode is activated and the mobile dock 30 and floor cleaner 10 returns to the home location.

[0025] Whilst the present invention has been described and illustrated with reference to particular embodiments, it will be appreciated by those of ordinary skill in the art that the invention lends itself to many different variations not specifically illustrated herein. By way of example only, certain possible variations will now be described.

[0026] The wireless communications protocol could be any suitable wireless communication protocol, for example Zigbee, Z-wave, or WIFI. The paired device may be the floor cleaner 10. In such an arrangement, the floor cleaner 10 will include a wireless communications unit arranged to communicate with the mobile dock 30, and a user interface which allows selection of the follow-me mode, or the come-to-me mode, and potentially the home mode.

[0027] The floor cleaner may be a dry floor cleaner, such as a vacuum cleaner or floor polisher which does not apply liquid to the floor. The mobile dock may still provide useful service functions to a dry floor cleaner, such as recharging the dry floor cleaner, cleaning the dry floor cleaner, and storing the dry floor cleaner when the user finishes their cleaning activity.

[0028] The mobile dock 30 may be arranged to carry one or more accessories for use with the floor cleaner.
