Problems solved by technology
Therefore, compared to electric vacuum cleaners that come with a power cord, electric fans can generate less attractive force
In addition, when the rechargeable battery is small, the moving distance of the self-propelled electric vacuum cleaner is short, and the area that can be cleaned becomes smaller.

Abstract
The present invention provides a small self-propelled electric vacuum cleaner (C) with high cleaning performance, comprising: a battery (B) for power supply; an electric blower (81) driven by the battery (B) for drawing dust into a dust collection case (K) from a suction port (17); a pair of left and right side brushes (40) arranged at a front lower part of a main body (50) and driven by the battery (B) to rotate in a substantially horizontal direction to collect the dust; a rotating brush (5) which is driven by the battery (B) and rotates in a substantially vertical direction to guide the dust to the suction port (17); a casing for accommodating the battery (B) and the electric blower (81); and a pair of drive wheels (61) provided at a lower portion of the casing and driven by the battery(B). The battery (B) and the side brushes (40) are disposed at the front of the pair of drive wheels (61). The rotating brush (5) and the suction port (17) are disposed behind the pair of drive wheels (61). The electric blower (81) is disposed between the pair of drive wheels (61).
Description
technical field [0001] The invention relates to a self-propelled electric vacuum cleaner. Background technique [0002] Conventionally, there is known a self-propelled electric vacuum cleaner that cleans while autonomously moving among electric vacuum cleaners. The self-propelled electric vacuum cleaner is equipped with a rechargeable battery as the power source. It mainly uses the rotating brush driven by the motor to sweep the dust into the dust box while moving forward. Since self-propelled electric vacuum cleaners use a rechargeable battery as a power source, the capacity that can be used is limited. As a result, electric blowers are able to generate less suction than electric vacuum cleaners that come with a cord. In addition, when the rechargeable battery is small, the moving distance of the self-propelled electric vacuum cleaner is short, and the area that can be cleaned becomes small. Therefore, rechargeable batteries need to be of a certain size. [0003] A pair...
