Solution Overview
Problem
Existing surface cleaning apparatuses require separate machines for vacuuming and extracting cleaning solutions, as they are not designed to handle large particulate matter or liquids effectively, leading to inefficiencies and increased storage needs.
Innovation Solution
A surface cleaning apparatus that operates in both vacuum and extractor modes, featuring a liquid distribution system, momentum separators, and cyclone separators to handle both dry and wet cleaning tasks, allowing for a single device to vacuum, apply, and extract cleaning solutions, with energy-efficient design and reduced footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate machines are used for vacuuming and extracting cleaning solutions, then each machine can be optimized for its specific function, but the user must store and manage multiple separate machines
Solution Approach 1:
The patent combines vacuum cleaning and liquid extraction functions into a single apparatus. The housing contains both a cyclone separator for particulate matter and a liquid separator for cleaning solutions, allowing the device to perform both dry and wet cleaning operations without requiring separate machines.
Solution Approach 2:
The apparatus is designed with universal functionality to handle both dry debris and liquid cleaning solutions through its dual separation system. The cyclone separator handles particulate matter while the liquid separator manages cleaning solutions, enabling one device to replace multiple specialized cleaning machines.
2Adaptability or versatility
If traditional extractors are used, then liquid extraction is effective, but large particulate matter cannot be removed requiring a separate vacuum cleaner
Solution Approach 1:
The separation system is segmented into two distinct stages: a cyclone separator for removing particulate matter and a liquid separator for extracting cleaning solutions. This segmentation allows each component to specialize in handling specific types of debris, improving overall cleaning effectiveness without requiring multiple separate devices.
3Productivity
If liquid treatment stage is positioned above solid particulate matter treatment stage, then all debris can be removed, but energy consumption increases due to lifting liquid upward
Solution Approach 1:
The patent positions the liquid separator at a lower elevation than the cyclone separator, utilizing vertical dimension arrangement to reduce energy consumption. Liquid is separated at a lower position where less energy is required to lift it, while the cyclone separator remains above to handle particulate matter, optimizing the energy efficiency of the separation process.

Function Achieved in This Case
Enables efficient cleaning of surfaces with a single apparatus, reducing energy consumption and storage requirements by effectively handling both dry and wet debris and liquids, while maintaining a compact design.
Implementation Method 1
a first stage liquid separator (e.g., a momentum separator)
Implementation Method 2
liquid requires substantially more energy to be drawn upwardly to a liquid treatment stage than entrained solid particulate matter
Implementation Method 3
a second stage cyclone separator comprising a cyclone chamber

AI summary
An upright surface cleaning apparatus such as an extractor has an upright section moveably mounted to a surface cleaning head. The upright section comprises a first stage liquid separator and a second stage cyclone separator, wherein the cyclone separator is positioned above and downstream from the first stage liquid separator when the upright section is in the storage position.
