The present disclosure relates to a cleaner station including a suction flow path having an inlet end configured to communicate with a dust bin of a cleaner, a dust collecting part connected to an outlet end of the suction flow path and configured to capture dust in the dust bin of the cleaner, and a spray module disposed at one side of the dust collecting part and configured to spray at least any one of the sterilization gas and particulates into the dust collecting part to kill insects existing in the dust collecting part, in which the spray module sprays the sterilization gas, which contains ozone or ion particles, into the dust collecting part, to kill insects existing in the dust collecting part.

A vacuum machine comprising: a housing for receiving vacuumed matter and at least two removably attachable accessories; sensing means for detecting the accessories; a control circuit communicatively coupled with the sensing means; the sensing means being arranged to generate a first signal to the control circuit representative of the presence of a first accessory, a second signal representative of the presence of two accessories, the control circuit being arranged to preventing operation of the vacuum machine when the first signal is received and to allow operation of the vacuum machine when the second signal.

A cleaner station suctions dust stored in a cleaner into the inside thereof and a method for controlling the cleaner station. The cleaner station includes: a housing which is coupled to a cleaner; a dust collection motor which is received within the housing and generates a suction force to suck dust within a dust bin of the cleaner; a dust collector which is received within the housing, is disposed above the dust collection motor, and collects the dust sucked from the inside of the dust bin by the dust collection motor; and a collector external sterilization unit which is received within the housing and is provided to cause a sterilization reaction on foreign substances present outside the dust collector.

In one embodiment, the invention provides a UV suction door mat that comprises an air duct having an inner and outer portion. The outer portion is configured to come in contact with footwear of a user. The inner portion comprises a UV emitter that emits UV radiation having wavelength in the UV-C region. The inner portion is coupled to a suction mechanism that sucks air in order to remove debris stuck to the bottom of the footwear. The suction is achieved by a vacuum pump connected to the air duct through a hose. The hose is coupled to a container configured to collect the debris, dust, etc. from the footwear. The UV suction door mat of the invention provides the advantage of simultaneous cleaning and disinfecting the footwear. The UV suction door mat may also comprise suitable sensors to activate the UV emitter and the vacuum.

A vacuum cleaner for air pollution prevention includes a main body, a blower, a filtering and cleaning assembly, and a gas detection module. The main body is configured to form a flow-guiding path. The blower is disposed in the flow-guiding path to guide air convection. The filtering and cleaning assembly is disposed in the flow-guiding path to filter and clean the air pollution source in the air guided by the blower. The gas detection module is disposed in the flow-guiding path to detect the air pollution source and transmits a gas detection data.

A pet waste removal device to remove pet waste from a surface, pet waste removal device including a main body including a plurality of wheels disposed at bottom corners of the main body to rotate such that the main body is propelled in a forward direction, a waste collecting aperture disposed at a front portion of the main body to receive the pet waste therethrough, a reverse axle including a plurality of rakes disposed on a surface of the reverse axle, wherein the reverse axle rotates in a direction opposite to the rotation of the plurality of wheels to allow the plurality of rakes to pick up the pet waste and introduce the pet waste through the waste collecting aperture, and a sanitizer compartment to store sanitizer therein and nozzles to spray the sanitizer out from the sanitizer compartment.

A system and method of software control and autonomy of a disinfection module for an autonomous or semi-autonomous cleaning device. The disinfection module control software resides on a computer with processor and memory. The disinfection module is connected to peripherals for sensing and localizing in the environment and controlling the actuators for the motion of the cleaning device. The disinfection module control software processes the sprayer's status, follows and plans paths to move the cleaning device to the spray targets, generates appropriate motion commands, and controls the disinfection module's pump, fan, LED, and electrostatic generator states.

An HVAC condensation line cleaning system, having: a housing with an internal chamber; an HVAC drain line draining into the internal chamber; a timed vacuum assembly that generates a vacuum in the internal chamber; and a check valve on the housing that: (a) opens permitting fluid to drain from the HVAC drain line out of the housing when the vacuum assembly is turned off, and (b) closes to generate suction in the HVAC drain line, thereby sucking contents of HVAC drain line into the internal chamber when the vacuum assembly is turned on.

A cleaning device (I) for suctioning a volumetric flow of particle-laden suction-air from an environment, includes: an air-receiving opening (2) having a first line cross section (21) for suctioning the volumetric flow of particle-laden suction-air from the environment in an active operating state; a liquid-receiving unit (4) having an immersion tube (3) for receiving a liquid, wherein the immersion tube (3) is connected at a first end (7) to the air-receiving opening (2) for conducting suction air and is designed such that at a second end (8) it is immersed into the receivable liquid such that, in an active operating state, the volumetric flow of particle-laden suction-air flows through the receivable liquid to trap the particles; and a vacuum generator (6) for generating the volumetric flow of suction-air in the active operating state.

A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.
