Integrated Floor Scrubber Head for Spray, Suction, and Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floor scrubbers require additional steps for water disposal after cleaning, as they direct significant water onto the floor, necessitating the use of mops or squeegees, and lack efficiency in liquid removal and compatibility with various cleaning equipment.
Innovation Solution
A floor scrubber design that incorporates a pivotably adjustable spray nozzle assembly with a built-in suction chamber for simultaneous or subsequent liquid removal, adaptable to different liquid and air conduits, and compatible with pressure washers and wet/dry vacuums, allowing for efficient liquid and chemical application and vacuum-assisted drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressurized liquid is directed onto the floor for cleaning, then cleaning effectiveness is improved, but water disposal complexity increases
Solution Approach 1:
The patent combines the liquid dispensing function and liquid removal function into a single integrated cleaning head assembly. The cleaning head includes both spray nozzles for dispensing pressurized liquid and a suction chamber with openings for removing liquid, eliminating the need for separate mopping equipment and simplifying the overall cleaning process.
Solution Approach 2:
The cleaning head is designed to perform multiple functions: dispensing pressurized liquid through spray nozzles, removing liquid through the suction chamber, and optionally directing pressurized air for drying. This multi-functional design replaces the need for multiple separate tools (scrubber, mop, squeegee, air blower) with a single versatile device.
2Adaptability or versatility
If additional equipment is used for liquid removal, then liquid disposal capability is improved, but device complexity increases
Solution Approach 1:
The cleaning head integrates multiple cleaning functions including liquid dispensing, liquid removal, and air drying capabilities within a single device. The suction chamber with floor-engaging openings enables liquid removal without requiring separate mopping or squeegeeing equipment.
Solution Approach 2:
The suction chamber acts as an intermediary mechanism between the floor surface and the vacuum source. It captures and removes liquid through its floor-engaging openings while being connected to a vacuum source, providing an efficient liquid removal pathway without direct mechanical contact like traditional mops or squeegees.
3Productivity
If the cleaning head maintains close proximity to the floor, then liquid removal efficiency is improved, but spatial separation for vacuum removal decreases
Solution Approach 1:
The suction chamber is designed with floor-engaging openings that extend downward toward the floor surface, effectively utilizing the vertical dimension to maximize proximity to the floor. This allows the suction openings to engage the floor surface directly, capturing liquid efficiently while maintaining the structural integrity of the cleaning head.
Solution Approach 2:
The suction chamber is positioned within the housing of the cleaning head, with its floor-engaging openings nested among the spray nozzles. This nested arrangement allows the suction chamber to be in close proximity to the floor surface while being protected and supported by the surrounding housing structure.

Function Achieved in This Case
Enables efficient floor cleaning by eliminating the need for post-cleaning water disposal, facilitating easy usage with existing equipment, and allowing for simultaneous chemical application and enhanced drying through vacuum-assisted air flow.
Implementation Method 1
downwardly directed liquid spray nozzles that communicate with a pressurized liquid supply
Implementation Method 2
a suction chamber or zone that has a suction opening in close proximity to the floor surface for removing liquid that has been directed onto the floor surface
Implementation Method 3
the wet/dry vacuum may be operated to direct a positive pressure air discharge through the vacuum line onto the floor surface to enhance drying

AI summary
A floor scrubber for cleaning floor surfaces that includes a cleaning head which defines a downwardly opening cleaning zone having a plurality of spray nozzles connected to a power washer pump for directing pressurized liquid flow streams onto the floor surface during a cleaning operation. The cleaning head further defines a separate downwardly opening vacuum zone connected to a wet/dry vacuum device operable for creating a vacuum pressure within the vacuum zone for removing liquid that has been directed onto the floor surface. The wet/dry vacuum device preferably further is operable for selectively directing a positive air flow into the vacuum zone to facilitate drying of the floor surface after cleaning and vacuum removal of the liquid.
