First Claim
Patent Images
1. A suction nozzle for a vacuum cleaner, comprising:
- a nozzle body comprising a nozzle suction inlet adapted to be fluidly interconnected to a source of suction;
a first side brush rotatably mounted to the nozzle body near a side of the nozzle body;
a first motor operably coupled with the first side brush for selectively rotating the first side brush;
a controller operably connected to the first motor; and
a first sensor operably connected to the controller and adapted to send an output signal to the controller upon sensing an obstacle;
wherein the controller energizes the first motor in response to the output signal from the first sensor.

Abstract
A suction nozzle for a vacuum cleaner includes one or more sensor(s) to sense an obstacle near or proximate to the suction nozzle. A side brush can be rotated or a working air path can be diverted based on a signal from the sensor(s).

14. A suction nozzle for a vacuum cleaner, comprising:
-
a nozzle body comprising a nozzle suction inlet; a first edge suction inlet provided near a side of the nozzle body; a first side brush rotatably mounted near the side of the nozzle body; a diverter assembly for selectively fluidly coupling one of the nozzle suction inlet and the first edge suction inlet with a source of suction and movable between a first position in which the nozzle suction inlet is fluidly coupled with the source of suction, and a second position in which the first edge suction inlet is fluidly coupled with the source of suction; a controller operably connected to the diverter assembly; and a first sensor operably connected to the controller and adapted to send an output signal to the controller upon sensing an obstacle; wherein the controller moves the diverter assembly to the second position and rotates the first side brush in response to the output signal from the first sensor. - View Dependent Claims (15, 16, 17, 18, 19)
