I took a lot of time taking pictures to illustrate my view!
This thread seems to encompass numerous topics. I've addressed a few below based on my experience. There are many pictures and examples to help tell how a straight nozzle acts vs. a rotational 45 degree wand vs. a swivel wand. I own each!
1. Offset-- Generally offset in a power nozzle is the position of the elbow in its relative position in the nozzle being offset from the middle. So general from the users point of the view the handle elbow might be closer to the right side of the nozzle as the motor takes up the majority of the left side of the unit.
*** See green Hoover PowerMax nozzle photo for example. Photo 1
2. "Fish Scales"--AKA: Top Airflow vents-- Panasonic/ Kenmore CenTecs response to newer style ultrasoft carpet fiber that numerous vacuum cleaners of all ages are struggling to clean and also a struggle for user to use. The attached link is a YouTube video produced by Panasonic, fully describing the interesting technology.
3. Bulky, Clunky, Junky, ugly power nozzle wand connections-- Many of the new elbows are swivel.
Some of you may be aware that I am a power nozzle canister extreme lover if you will! My Hoover Celebrity, Windtunnel and PowerMax nozzles are a straight connection no rotation or anything. Eureka Rotomatic, WorldVac and Hoover Quadraflex rotate 45 degrees-- the Quadraflex system is the best because it will lock into either position.
Perhaps some of you have experienced similar where the weight of the hose causes the wand to constantly rotate within the groove where the round pin is housed within a free open sliding rotation groove. Some examples are: Kenmore standard- NON-QUICK release systems wand systems and numerous Eurekas.
***See photo of Eureka power nozzle wand as example: Photo 2, Photo 3 shows how the hose wands to store sideways rather than facing front due to weight.
Follow numerous photos taken of my Simplicity Verve canister unit to see some of the motions now capable with a swivel connector. Please keep in mind that the wand to power nozzle connections bulk is due to the following:
1. Quick disconnect foot pedal system
2. Streamlined system of no exposed wiring, all electrical is in the wands
3. Wand storage hook to connect wand to the rear of the canister for temporary parking or connection to the base of the suction unit for compact storage
4. Full maneuvering, rotating in either direction, swivel elbow that locks into parking position with a pedal release.
What the swivel elbow does different compared to my other power nozzles is allow the user to turn the nozzle in a different direction in an easier motion with smaller turning radius. In relocating the rotation point from the Eureka power nozzle above, it allows the hose to still turn sideways for easier under furniture cleaning but also starts the nozzle turning so the user doesn't have to fight a fixed wheel steering design as much. ***Photo 9 shows it best
***You could compare the situation to trying to steer a tractor trailer to make a turn (traditional power nozzle hookup) compared to a standard sedan completing a turn (swivel connection power nozzle). The sedan has a smaller turning radius. Or similarly imagine a walk behind lawn mower, if the companies added a swiveling handle where it connected to the mower, how that might make turning the fixed straight wheeled mower easier to steer for starting the next row or even just rotation along of the perimeter of your property easier!
I have no issues and find it very easy to rotate and steer the Simplicity power and Rainbow nozzle under my coffee table, chairs or under the bed as you can see from a few of the photos. Also yes, that is my Hoover Convertible Elite stored under the bed!!
I think if you've ever tried one of these types of wands, you might learn to like it. It may take a decent timed vacuuming session to fully experience and try all of the angles that this connection can do. Due to the flexibility it actually in some ways more durable compared to a fixed elbow where some users have broken them over the years trying to steer wrong. It also reduces the urge to want to pick up the nozzle and move it to another area as some users do.
Some power nozzles with this system that have it working well include: Kenmore Swivel steering nozzle-- first one was a red colored series that debuted about 4 years ago. Current model E2 Type 12 Rainbow, Riccar, Simplicity full sized power nozzles.
***Aerus Lux has had a rotating elbow on their TOL power nozzle for years, yet they are the only one I've been informed of to have the most durability issues.
Their's rotates sideways but doesn't offer the same swivel steer directions that the Rainbow and Riccar are able to do and be extremely successful at for user ease and durability!!
Thank you for reading, enjoy the photos and please comment! I apologize for the length of this post but it's detailed and at least has lots of photos!!
