Floor cleaning nozzle for surface cleaning apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses struggle with effective edge cleaning, often requiring additional tools and manual labor to clean along edges such as baseboards and walls, while maintaining efficient floor cleaning.
Innovation Solution
A floor cleaning nozzle with a dual brushroll system, including a main brushroll and an edge brushroll, integrated with a squeegee and fluid dispensers, designed for both floor and edge cleaning, featuring a removable brushroll assembly and a brushroll cover for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single brushroll is used for floor cleaning, then floor cleaning efficiency is improved, but edge cleaning capability deteriorates
Solution Approach 1:
The brushroll is segmented into two distinct components: a main brushroll for floor cleaning and an edge brushroll for edge cleaning. The edge brushroll is positioned at the lateral end of the main brushroll and extends through an edge cleaning aperture, allowing each segment to perform its specialized function independently while being driven by a single motor.
Solution Approach 2:
Different regions of the cleaning apparatus are given different properties: the main brushroll uses agitation material suitable for broad floor surfaces, while the edge brushroll uses agitation material optimized for narrow edge areas. The edge cleaning aperture is specifically positioned and sized to allow the edge brushroll to access wall junctions and baseboards effectively.
2Adaptability or versatility
If additional cleaning tools are added for edge cleaning, then edge cleaning capability is improved, but device complexity increases
Solution Approach 1:
The edge cleaning function is merged with the main floor cleaning function by integrating the edge brushroll into the lateral end of the main brushroll assembly. Both brushrolls share a common drive motor and are housed within a single nozzle, eliminating the need for separate edge cleaning tools while maintaining functional independence.
Solution Approach 2:
The cleaning apparatus is designed with multi-functionality, where a single nozzle assembly performs both floor cleaning and edge cleaning operations. The edge cleaning aperture and edge brushroll are integrated into the main nozzle structure, allowing the device to handle multiple cleaning tasks without requiring additional specialized tools.
3Adaptability or versatility
If a dual brushroll system is integrated, then cleaning versatility is improved, but ease of operation deteriorates
Solution Approach 1:
The brushroll assembly is designed for self-service maintenance, where the user can easily remove the entire brushroll assembly as a unit from the nozzle housing for cleaning and maintenance. The assembly includes a carrier that facilitates easy installation and removal, allowing users to maintain both brushrolls without requiring disassembly of the entire device.

AI summary
A floor cleaning nozzle for a surface cleaning apparatus includes a nozzle housing having a brushroll compartment, a suction inlet opening to the brushroll compartment, a main brushroll, and an edge brushroll. The edge brushroll is connected to an end of the main brushroll and is rotatable therewith about an axis. The edge brushroll can at least partially extend through an edge cleaning aperture in the nozzle housing.
