A spraying device for spraying an enclosure with a liquid cleanser, wherein the device comprises a reservoir for containing the liquid cleanser or is adapted for receiving a detachable cartridge comprising a reservoir for containing the liquid cleanser, • and wherein the device further comprises ∘ a metering system comprising a metering chamber, a weir member, and a conduit means, ∘ a spray head containing a vibrating mesh spray actuator, and ∘ an electronic control circuit for controlling the spray actuator; • whereby ∘ the metering chamber comprises an inlet opening and an outlet opening, and whereby the weir member is located between the reservoir and the metering chamber and ∘ the device is rotatable between a first recharging orientation and a second dispensing orientation; • and whereby in the recharging orientation, ∘ the metering chamber is located below the reservoir and is in fluid communication therewith via the inlet opening; • and whereby in the dispensing orientation: ∘ the weir member extends upward from the lower wall of the reservoir and the metering inlet opening is located above the weir member, ∘ the metering chamber is in fluid communication with the vibrating mesh spray actuator via the metering outlet opening and the conduit means, and ∘ the spray head is located below the metering chamber and is adapted for spraying in downward direction; • and whereby the conduit means comprises an element selected from a check valve and a channel, whereby ∘ if the element is said check valve, the check valve is closed when the device is in the recharging position and opened when the device is in the dispensing orientation, ∘ and if the element is said channel, the channel communicates with the metering chamber via a channel inlet opening and communicates with the spray head via a channel outlet opening and whereby, when the device is in the recharging orientation, the channel extends in an upward direction from the metering chamber and the spray head is located above and away from the metering chamber. • and wherein the device further comprises ∘ a metering system comprising a metering chamber, a weir member, and a conduit means, ∘ a spray head containing a vibrating mesh spray actuator, and ∘ an electronic control circuit for controlling the spray actuator; ∘ a metering system comprising a metering chamber, a weir member, and a conduit means, ∘ a spray head containing a vibrating mesh spray actuator, and ∘ an electronic control circuit for controlling the spray actuator; • whereby ∘ the metering chamber comprises an inlet opening and an outlet opening, and whereby the weir member is located between the reservoir and the metering chamber and ∘ the device is rotatable between a first recharging orientation and a second dispensing orientation; ∘ the metering chamber comprises an inlet opening and an outlet opening, and whereby the weir member is located between the reservoir and the metering chamber and ∘ the device is rotatable between a first recharging orientation and a second dispensing orientation; • and whereby in the recharging orientation, ∘ the metering chamber is located below the reservoir and is in fluid communication therewith via the inlet opening; ∘ the metering chamber is located below the reservoir and is in fluid communication therewith via the inlet opening; • and whereby in the dispensing orientation: ∘ the weir member extends upward from the lower wall of the reservoir and the metering inlet opening is located above the weir member, ∘ the metering chamber is in fluid communication with the vibrating mesh spray actuator via the metering outlet opening and the conduit means, and ∘ the spray head is located below the metering chamber and is adapted for spraying in downward direction; ∘ the weir member extends upward from the lower wall of the reservoir and the metering inlet opening is located above the weir member, ∘ the metering chamber is in fluid communication with the vibrating mesh spray actuator via the metering outlet opening and the conduit means, and ∘ the spray head is located below the metering chamber and is adapted for spraying in downward direction; • and whereby the conduit means comprises an element selected from a check valve and a channel, whereby ∘ if the element is said check valve, the check valve is closed when the device is in the recharging position and opened when the device is in the dispensing orientation, ∘ and if the element is said channel, the channel communicates with the metering chamber via a channel inlet opening and communicates with the spray head via a channel outlet opening and whereby, when the device is in the recharging orientation, the channel extends in an upward direction from the metering chamber and the spray head is located above and away from the metering chamber. ∘ if the element is said check valve, the check valve is closed when the device is in the recharging position and opened when the device is in the dispensing orientation, ∘ and if the element is said channel, the channel communicates with the metering chamber via a channel inlet opening and communicates with the spray head via a channel outlet opening and whereby, when the device is in the recharging orientation, the channel extends in an upward direction from the metering chamber and the spray head is located above and away from the metering chamber.
