Method for operating a floor cleaning system, and floor cleaning system for use of the method

The invention relates to a method for operating a floor cleaning system having a central suction station with which there is associated a self-propelled and self-steering suction appliance, dirt being picked up from a floor surface that is to be cleaned by means of the suction appliance and being transferred into a dirt collection vessel of the suction appliance, and the suction station having a suction unit, and the dirt collection vessel being sucked out by means of the suction unit. To refine the method in such a manner that the levels of noise produced by the floor cleaning system can be reduced, it is proposed, according to the invention, that the suction unit is optionally operated with a maximum suction power or a reduced suction power. The invention also proposes a floor cleaning system for carrying out the method.

Obstacle sensing system for an autonomous cleaning apparatus

An obstacle-sensing system for carriers, particularly autonomous carriers such as robot vacuum cleaners, enables the carriers to disengage themselves from any obstacle or obstruction with which they come into physical contact and proceed past the obstacle or obstruction. The obstacle-sensing system is established by constructing a carrier to have front and rear sections which, normally, are in a neutral relationship with respect to one another but which move relative to one another when the front section physically engages an obstacle or obstruction. The relative movement activates a guidance and control system that maneuvers the carrier around the obstacle or obstruction.

Cleaner

Only when a wall side and the vicinity of an obstacle are cleaned, a side brush is operated and the cleaning is carried out, and when any other place than the wall side and the vicinity of the obstacle is cleaned, the side brush is maintained in a stoppage state. When a place such as the wall side or the vicinity of the obstacle in which dust is easy to accumulate is cleaned, the side brush is operated to enhance the dust collecting property. When any other place than the wall side or the vicinity of the obstacle is cleaned, the side brush is stopped to suppress power consumption and generation of a noise. A judgment processing portion detects based on a detection signal from an obstacle detecting portion that a cleaner is approaching a wall or an obstacle. In response to such detection, the judgment processing portion instructs a travel steering portion to carry out immediate rotation and change of a travel direction, or travel along a wall side. Also, the judgment processing portion instructs a side brush driving portion to drive a side brush only in the rotation and in the wall side travel, and to stop the side brush in straight advance travel.

Wheel support arrangement for an autonomous cleaning apparatus

InactiveUS7275280B2Easily climbs over or otherwise avoids objectsPromote sportsAutomatic obstacle detectionTravelling automatic controlDrive wheelEngineering
A carrier, such as an autonomous cleaning apparatus, has a self-adjusting wheel assembly that can move vertically, thereby enabling the carrier to readily pass over a surface. The wheel assembly may include microswitch, which activates a control mechanism for the carrier when a wheel assembly is in a predetermined position along its path of vertical movement. Rollers can be located at the bottom of the carrier to function in cooperation with the wheel assemblies so as to facilitate the ability of the carrier to pass over obstacles. This ability may be enhanced by constructing the bottom of the front portion of the carrier so that it is slanted or inclined upwardly in a direction outward from the bottom of the carrier. A driving wheel may be rotatably attached to a wheel support, and which may also support a power source and a transmission.

Sensors and associated methods for controlling a vacuum cleaner

A cleaning appliance includes a housing with a brushroll and a wheel mounted thereto. A floor-type sensor is disposed within a mounting tube secured to the housing. The floor-type sensor emits sonic energy toward a surface being traversed by the cleaning appliance and receives corresponding sonic energy reflected by the surface. A comparator, electrically coupled to the floor-type sensor, compares the received reflected sonic energy to one or more associated predetermined values to determine the type of surface being traversed. A processor analyzes the results of the comparison and controls at least one of a suction fan, said wheel and said brushroll, based at least in part on the analysis.
