Bare Floor Cleaner Mode Switching for Dry Suction and Wet Mopping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning bare floor surfaces are inefficient and require multiple tools, leading to physical exertion, damage to surfaces, and ineffective dirt and solution management, particularly in transitioning between dry and wet cleaning modes.
Innovation Solution
A wet/dry bare floor cleaner with a pivotally connected handle that allows for easy switching between dry and wet modes, featuring a recovery system for dirt collection, a fluid delivery system with a mechanical interlock to prevent solution dispensing during dry mode, and a motor/fan assembly that is deactivated when cleaning fluid is applied, along with support glides to reduce surface contact and friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional broom and dustpan are used to remove dry debris, then the debris can be collected, but it is difficult to transfer the entire debris pile into the dustpan and the user must bend over which is inconvenient and painful
Solution Approach 1:
The patent combines the broom and dustpan functions into a single integrated device. The cleaning head includes both bristles for sweeping and a collection chamber for capturing debris, eliminating the need to switch between separate broom and dustpan tools and allowing debris to be collected directly during the sweeping motion.
Solution Approach 2:
The cleaning device is designed to perform multiple functions: dry debris removal, wet mopping, and solution application. The cleaning head can be configured with different attachments (bristles for dry cleaning, absorbent material for wet cleaning) and the handle can be adjusted to different angles, making it a universal tool for various floor cleaning tasks.
2Productivity
If a traditional sponge or rag mop is used to apply cleaning solution, then the mop can loosen dirt and absorb solution, but the mop must be frequently placed in a bucket to soak up solution which becomes dirty and cold, and movement of the mop requires physical exertion
Solution Approach 1:
The device includes an automatic solution application system with a reservoir and dispensing mechanism that applies cleaning solution automatically as the device moves across the floor. This eliminates the need for the user to manually dip and wring a mop in a bucket, and the solution is applied at the right moments without requiring additional physical effort.
Solution Approach 2:
The cleaning solution is pre-loaded into a reservoir attached to the handle. The system is prepared in advance so that when the cleaning operation begins, the solution is already positioned and ready to be dispensed automatically, eliminating the need for repeated trips to a bucket during the cleaning process.
3Adaptability or versatility
If textured cloths are used as an agitator, then they can loosen dirt, but they require physical exertion and regular replacement and are not as absorbent as mops
Solution Approach 1:
The device features a motor-driven rotating brush or pad that dynamically agitates the cleaning solution and loosens dirt through rotational motion. This mechanical agitation replaces the need for manual scrubbing with textured cloths, reducing physical exertion while maintaining effective dirt removal. The rotating element can be raised or lowered as needed.
Solution Approach 2:
The patent replaces the manual mechanical action of scrubbing with textured cloths with an automated motor-driven rotating brush or pad. This substitution eliminates the need for the user to apply physical force and reduces maintenance requirements compared to replaceable cloth agitators.
4Productivity
If vacuum cleaners designed for carpets are used to vacuum dry debris, then the debris can be removed, but the vacuum cleaner can damage bare surfaces
Solution Approach 1:
The device uses a specialized cleaning head with soft bristles or pads specifically designed for bare floor surfaces. These local components have different properties than carpet vacuum attachments - they are softer and less abrasive to prevent surface damage while still effectively capturing dry debris through gentle agitation and suction.

AI summary
A bare floor cleaner has a foot with a dry suction nozzle and a handle assembly pivotally connected to the foot assembly. A diverter mounted in the working air conduit between the foot assembly and the handle assembly is movable by movement of the handle assembly between a dry suction position and a wet mop position for selectively at least partially blocking working air flow from the dry suction nozzle to a collection assembly. A fluid delivery system includes a user operated trigger for actuating the fluid delivery system to distribute fluid in the wet mop position and deactivating a motor/fan assembly. A trigger lock prevents cleaning solution from being distributed when the handle is in dry mode position. The fluid delivery system includes a heating element to raise the temperature of the cleaning solution before it is distributed to the surface to be cleaned. Support glides on the foot reduce the surface area contact between the foot pad and the surface to be cleaned.
