Pros - might be more convenient sometimes
Cons - Its pricey compared to standard
- hide a hose .. in my experience does not have a perfect seal , so slight but perhaps not significant suction leek.
- The solution hose inside decreases the vacuum hose size and must cause a bit of airflow resistance ( perhaps not significant)
- u will have to occasionally clear trapped fluff from the inside where the it gets snagged on the internal solution hose
- some of those black hoses contract a fair bit compared to others when vacuum is applied
