Technical Field
[0001] The present invention relates to a tool for the cleaning of surfaces.
[0002] In particular, the present invention is intended for the cleaning of flat surfaces
such as e.g. a floor.
Background Art
[0003] The cleaning systems of known type provide for the use of a tool comprising a handle,
which is adapted to move the tool itself onto the surface to be cleaned by an operator,
a base, associated with one end of the handle, and a cleaning element, associable
with the base and adapted to clean the surface as a result of the movement of the
tool.
[0004] Specifically, the cleaning element is of the type of a cloth and can possibly be
moistened with a cleaning liquid.
[0005] The cleaning element is removable from its base so it can be replaced or to restore
the cleaning liquid.
[0006] The cleaning process provides for the movement of the tool by an operator in an area
of use as well as the interaction of the cleaning element with the surface.
[0007] In those situations where high hygiene conditions must be ensured, the operator must
keep track of the activities carried out and report them to a supervisor. Therefore,
the detection, monitoring and reporting of operations are entirely the responsibility
of the operator.
[0008] However, it is clear that this control system is extremely inaccurate and imprecise,
since the operator is not able to detect and report precise and detailed information
on all the activities carried out, such as e.g. the exact surface covered by the cleaning
element or the actual achievement of all the points in the area of use.
[0009] In addition, reporting by the operator does not allow for a continuous and steady
update of the activities carried out, unless there are continuous interruptions in
the cleaning operations.
[0010] Again, it is important to note that the operator's intervention is inevitably subject
to human error.
Description of the Invention
[0011] The main aim of the present invention is to devise a tool for the cleaning of surfaces
which allows detecting and reporting the degree of surface cleaning in an accurate
and precise manner.
[0012] Another object of the present invention is to devise a tool for the cleaning of surfaces
which allows objective detection of predefined cleaning parameters. An additional
object of the present invention is to devise a tool for the cleaning of surfaces which
allows planning and real-time updating of the cleaning operations to be carried out.
[0013] Still one object of the present invention is to devise a tool for the cleaning of
surfaces which allows effectively monitoring the performance carried out.
[0014] Another object of the present invention is to devise a tool for the cleaning of surfaces
which allows the aforementioned drawbacks of the prior art to be overcome within the
scope of a simple, rational, easy and effective to use as well as affordable solution.
[0015] The aforementioned objects are achieved by the present tool for the cleaning of surfaces
having the characteristics of claim 1.

[0016] Other characteristics and advantages of the present invention will become more apparent
from the description of a preferred, but not exclusive, embodiment of a tool for the
cleaning of surfaces, illustrated by way of an indicative, yet nonlimiting example,
in the accompanying tables of drawings wherein:

Embodiments of the Invention
[0017] With particular reference to these figures, reference numeral 1 globally indicates
a tool for the cleaning of surfaces.
[0018] The tool 1 comprises at least one cleaning device 20 movable on a work surface F
to be cleaned by an operator in at least one area of use.
[0019] In the context of the present disclosure, the expression "work surface" means a substantially
flat, horizontal surface, such as e.g. a floor. At the same time, the expression "area
of use" means a room, a premise or otherwise an enclosed place having a work surface
F to be cleaned and wherein the tool 1 is intended to be used.
[0020] The cleaning device 20 comprises at least one handle 2 which is adapted to move the
cleaning device 20 by an operator.
[0021] The cleaning device 20 comprises at least one base 3 associated with one end of the
handle 2. Specifically, during use, the base 3 is arranged in the proximity of the
work surface F.
[0022] The cleaning device 20 comprises articulated linking means 21 positioned between
the handle 2 and the base 3 and adapted to allow a rotation of the base itself by
an angle substantially equal to 360°.
[0023] The cleaning device 20 also comprises at least one cleaning element 4 associable
with the base 3 and adapted to clean the work surface F as a result of the movement
of the tool itself.
[0024] The cleaning element 4 is of the type of a cloth, made of natural and/or synthetic
fibers.
[0025] The cleaning element 4 can be wetted with a cleaning liquid soaked in the fibers
of the cloth and adapted to clean the work surface F.
[0026] It cannot however be ruled out that the cleaning element 4 may be dry. Conveniently,
the cleaning element 4 is associated with the base 3 in a removable manner.
[0027] For this purpose, the cleaning device 20 comprises removable fastening means 31 positioned
between the base 3 and the cleaning element 4.
[0028] In this way, the cleaning element 4 may be easily removed from the base 3 to restore
the content of cleaning liquid or to be replaced when worn.
[0029] In particular, the removable fastening means 31 may be of the type of hooks, Velcro,
stickers or the like.
[0030] According to the invention, the tool 1 comprises at least one electronic detection
device 5 associated with the cleaning device 20 and configured to generate at least
one datum representative of the cleaning of the work surface F.
[0031] The at least one representative datum comprises at least one of: a datum of position
of the cleaning device 20 in the area of use, a datum of space covered, a datum of
work surface F covered, a datum of distance of the cleaning device 20 from the work
surface F, a datum of working time, a datum of dwelling time in the area of use and
a datum of cleaning efficiency.
[0032] In other words, the tool 1 allows automatically detecting the parameters representative
of the cleaning of the work surface F freeing itself from the need of the operator's
intervention.
[0033] The tool 1 allows, therefore, obtaining a quick and objective indication of the degree
of cleaning of the work surface F.
[0034] Advantageously, the electronic detection device 5 comprises detecting sensors 6 configured
to detect at least one of: a motion signal of the cleaning device 20 on said work
surface F, at least one position signal of the cleaning device 20 in the area of use,
a speed signal of the movement of said cleaning device 20 and a distance signal of
the electronic detection device 5 with respect to said work surface F.
[0035] According to a preferred embodiment shown in the figures, the electronic detection
device 5 is associated with the cleaning device 20 in a removable manner. Such an
embodiment allows the electronic detection device 5 to be easily removed and replaced
from the cleaning device 20, e.g. in case of maintenance jobs or in case of failure
of the cleaning device itself. At the same time, such solution allows the electronic
detection device 5 to be used on different cleaning devices 20. Furthermore, such
solution allows the electronic detection device 5 to be used on cleaning devices 20
already existing on the market.
[0036] Usefully, for this purpose, the tool 1 comprises removable attachment means positioned
between the electronic detection device 5 and the cleaning device 20, of a type known
to the person skilled in the art and not shown in detail in the figures.
[0037] In particular, the electronic detection device 5 is associated with the base 3. In
this way, the detecting sensors 6 are able to detect signals as representative as
possible related to the movement of the base 3 on the work surface F. According to
an alternative embodiment, on the other hand, the electronic detection device 5 is
locked together with the cleaning device 20 and, specifically, with the base 3.
[0038] The electronic detection device 5 also comprises at least one electronic unit 7 operationally
connected to the detecting sensors 6 and configured to process at least one of the
aforementioned signals and to generate at least one of the representative data.
[0039] In more detail, the electronic unit 7 comprises a processing unit 7a responsible
for processing the signals received and for controlling the set of sensors connected
to the electronic unit itself.
[0040] The electronic unit 7 comprises at least one memory unit 8 configured to store at
least one of the representative data.
[0041] In particular, the memory unit 8 receives and stores the data processed by the processing
unit 7a.
[0042] Usefully, the memory unit 8 is also configured to store the signals detected by the
detecting sensors 6.
[0043] The detecting sensors 6 comprise at least one motion sensor 15 configured to detect
the movement of the cleaning device 20 on the work surface F and to generate a corresponding
motion signal.
[0044] Specifically, the motion sensor 15 comprises at least one optical sensor.
[0045] The motion sensor 15 allows detecting the position of the cleaning device 20 with
respect to a plane X-Z.
[0046] The detecting sensors 6 also comprise at least one position sensor 9 configured to
detect the position of the cleaning device 20 and to generate a corresponding position
signal.
[0047] Conveniently, the position sensor 9 comprises at least one of either an accelerometer
device or a gyroscope device.
[0048] The position sensor 9 is used to determine the orientation and direction along which
the cleaning device 20 is moved.
[0049] By means of the position sensor 9 and the motion sensor 15, the location of the cleaning
device 20 may be determined at any time.
[0050] This makes it possible to determine where the tool 1 has been positioned in the area
of use and whether the work surface F has been properly cleaned at every point thereof.
[0051] The electronic unit 7 is also configured to process the position signal and the motion
signal to obtain the datum of surface covered.
[0052] Through these signals it is therefore possible to determine the representative datum
of the surface covered by the cleaning element 4 during the operations. The detecting
sensors 6 also comprise at least one Real Time Clock (RTC) module configured to determine
the time of use.
[0053] Advantageously, the detecting sensors 6 comprise at least one speed sensor 10 configured
to detect the speed of movement of the cleaning device 20 on the work surface F and
to generate a corresponding speed signal.
[0054] The speed sensor 10 comprises at least one IMU (Inertial Measurement Unit) device.
[0055] Thus, the electronic detection device 5 also allows the acquisition of a datum of
speed traveled by the cleaning device 20 during the operation so as to establish a
degree of accuracy in the cleaning of the work surface F.
[0056] The electronic unit 7 is also configured to process the speed signal and the time
of use to obtain the datum of working time and the datum of dwelling time in the area
of use.
[0057] Usefully, the detecting sensors 6 also comprise at least one distance sensor 16 configured
to detect the distance of the electronic detection device 5 from the work surface
F and to generate a corresponding distance signal.
[0058] The distance sensor 16 comprises at least one Time Of Flight (TOF) sensor. The distance
sensor 16 allows determining when the cleaning device 20 is in the proximity of the
work surface F.
[0059] Advantageously, the electronic unit 7 is configured to operate/deactivate at least
one of the motion sensor 15, the position sensor 9 or the speed sensor 10 depending
on the distance signal.
[0060] In other words, the electronic unit 7 is configured to detect the signals by the
detecting sensors 6 only when the cleaning device 20 is actually in contact with the
work surface F.
[0061] The tool 1 allows, therefore, an effective processing of the signals and allows providing
extremely representative and reliable data of the degree of cleaning, thus avoiding
possible human errors.
[0062] The electronic unit 7 is usefully configured to process at least the speed signal,
the motion signal and the distance signal to generate the datum of cleaning efficiency.
[0063] According to a possible embodiment of the present invention, the detecting sensors
6 comprise at least one presence sensor 11 configured to detect the presence of the
cleaning element 4 associated with the base 3 and to generate a corresponding presence
signal.
[0064] The presence sensor 11 comprises at least one of either a contact sensor or an optical
sensor.
[0065] Conveniently, the electronic unit 7 comprises transfer means 12 of the data which
are configured to transfer at least one of the data to a remote device R. The transfer
means 12 are operationally connected to the memory unit 8.
[0066] The remote device R may be, e.g., a PC, a smart-phone or the like. Specifically,
the transfer means 12 are configured to also transmit the signals detected by the
detecting sensors 6 and stored in the memory unit 8 to be processed by the remote
device R.
[0067] The transfer means 12 comprise at least one of either a serial transmission device
or a radio wave transmission device.
[0068] The serial transmission device is e.g. of the type of a USB port.
[0069] The radio wave transmission device is selected out of a Bluetooth device and a Wi-Fi
device.
[0070] Depending on the type of transfer means 12, therefore, the data may be transferred
at the end of operations by means of a connection to remote computers or in real time.
[0071] Conveniently, the electronic detection device 5 comprises energy storage means 13
of the type of a battery, adapted to power all the electronic user points of the electronic
detection device itself.
[0072] The energy storage means 13 allow for convenient use of the tool 1 without the need
for a mains connection.
[0073] Preferably, the energy storage means 13 are of the rechargeable type.
[0074] To this end, the electronic detection device 5 comprises charging means 14 operationally
connected to the energy storage means 13.
[0075] In the embodiment shown in the figures, the charging means 14 are of the type of,
e.g., a USB port.
[0076] The operation of the tool according to the present invention is as follows.
[0077] Once the cleaning element 4 has been mounted on the base 3, the tool 1 is positioned
on the work surface F.
[0078] By means of the distance sensor 16, the electronic detection device 5 detects the
grounding of the tool 1 and the signal acquisition is triggered by the electronic
unit 7.
[0079] During the cleaning operations, the tool 1 is moved over the work surface F by means
of the handle 2.
[0080] The position sensor 9 and the motion sensor 15 constantly detect a position signal
of the cleaning device 20 in the area of use.
[0081] The speed sensor 10 detects a movement speed signal of the tool 1 on the work surface
F and allows acquiring the datum of speed and of surface covered.
[0082] By means of the module RTC it is also possible to process the datum of working time.
[0083] The aforementioned data and/or signals are stored in the memory unit 8.
[0084] At the end of the operations, the tool 1 is lifted from the work surface F, the distance
sensor 16 determines the change in position and the data acquisition is interrupted.
[0085] The data and/or signals stored in the memory unit 8 are transferred to the remote
device R by means of the transfer means 12.
[0086] According to a further aspect, the present invention also relates to an electronic
detection device 5 for cleaning devices.
[0087] The electronic detection device 5 according to the invention is associable with a
cleaning device 20 movable by an operator on a work surface F to be cleaned in an
area of use.
[0088] In particular, the electronic detection device 5 is associable with the cleaning
device 20 in a removable manner.
[0089] The electronic detection device 5 is configured to generate at least one representative
datum of the cleanliness of the work surface F.
[0090] The at least one representative datum comprises at least one of: a datum of position
of the cleaning device 20 in the area of use, a datum of space covered, a datum of
work surface F covered, a datum of distance of the cleaning device 20 from the work
surface F, a datum of working time, a datum of dwelling time in the area of use and
a datum of cleaning efficiency.
[0091] It has in practice been ascertained that the described invention achieves the intended

of surfaces according to the present invention enables the degree of cleaning of the
surfaces to be precisely and accurately detected and reported. Thanks to the electronic
detection device, the tool allows objective detection of predefined cleaning parameters,
