The method also includes presenting, on a display of the mobile device, a training map depicting portions of the area traversed by the autonomous cleaning robot during the training run and presenting, on the display of the mobile device, an interface configured to allow the training map to be stored or deleted. The method also includes initiating additional training runs to produce additional training maps and presenting a master map generated based on a plurality of stored training maps.

A surface cleaning apparatus has a suction motor actuator that is actuatable to actuate the suction motor to operate in a low mode of operation and to operate in a high mode of operation. A first power pack provides a first level of on board power that is available to power the surface cleaning apparatus. A second power pack provides a second level of on board power is available to power the surface cleaning apparatus, the second level of on board power is greater than the first level of on board power. Each of the low and high modes of operation are enabled when the first power pack is provided to power the surface cleaning apparatus and when the second power pack is provided to power the surface cleaning apparatus. When the second power pack is provided to power the surface cleaning apparatus, an operating power level provided to the suction motor during at least one of the low and high modes of operation is increased.

A self-propelled floor processing device with an evaluation unit, which is designed to navigate the floor processing device within an environment based on an area map and, during a movement, to determine a behavior parameter of the floor processing device and a movement path of the floor processing device. The evaluation unit is set up to analyze the behavior parameter and movement path, automatically determine a no-go area which the floor processing device must not traverse depending on the result of the analysis, and enter the determined no-go area in the area map or change a no-go area already entered in the area map.

A surface cleaning apparatus having a fluid delivery system and a fluid recovery system is provided with a housing including an upright body and a base coupled with the upright body. Cleaning fluid and electrical wiring can be routed between the upright body and the base via a yoked spine section of the upright body.

Disclosed are devices, systems, and methods for modular vacuum cleaners. An example vacuum cleaner system includes a canister vacuum cleaner device and a robotic vacuum cleaner device, where the robotic vacuum cleaner is removably coupled to or is digitally communicable with the canister vacuum cleaner device. The canister vacuum cleaner device comprises a canister to collect debris, a vertical hollow structure that located towards a rear of the canister and coupled to the canister, a flexible extendable hose, and a housing located below the canister, wherein the housing includes a retractable electrical cord. The robotic vacuum cleaner device comprises: a storage area to collect debris, a battery, a plurality of wheels that are removably coupled to one or more motors, and a lever or a valve structured to direct debris either to the storage area or to the canister.

Disclosed are devices, systems and methods for air purification in an airflow tract of vacuum cleaners. In some aspects, an air purification system for a vacuum cleaner comprises an ultraviolet (UV) light unit disposed in a first location within the vacuum cleaner along an airflow pathway, configured to emit UV light at air containing particles including dust, dirt, and microbes while the air containing the particles is flowing in the airflow pathway where the UV light unit is disposed; and a particle filter unit disposed in a second location within the vacuum cleaner along the airflow pathway, the particle filter unit comprising one or both of a high-efficiency particulate air (HEPA) filter and an active carbon filter.

A material determining device comprising a first image sensor, a second image sensor, and a light source is provided. The material determining method comprises: (a) sensing a first image by the first image sensor according to light from the light source; (b) sensing a second image by the second image sensor according to the light; and (c) determining whether material corresponding to material images in the first image and the second image is first type of material or second type of material, according to locations of the material images in the first image and the second image and according to shapes of the material images in the first image and the second image. By this way an electronic device using the material determining device can properly operate according to the type of material.

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.
