I used to have a twin chamber wind tunnel bagless. Bought it on eBay as a factory reconditioned model when I had a two story house with a lot of carpet for a second vacuum at the time. It was ok for cleaning carpet but I didn’t like that the hose would fall out of its port and it always seemed to be suck8mg from the hose somewhat, there was no switch or connection to shut off the hose suction. The hose just was supposed to be inserted in a dead port when not in use but would often fall out and swing about while
Vacuuming. It had the small turbo nozzle which I still have and other attachments but the plastic cover broke for the attachments but it wasn’t really something that was needed anyway, more of a hassle than anything else...that cover. I gave it away to the housekeeper at one point when I was tired of it and I think a plastic part that kept it off the carpet when standing to use tools so it wouldn’t burn the carpet broke too. It still cleaned the carpets well and I would vacuum the screen and paper filter with my Electrolux when I emptied it. I always felt like when the screen would get coated with lint it wasn’t sucking as efficiently and that would happen quickly.
I recently I obtained a barely used Hoover Platinum upright and the nozzle says wind tunnel on it and I did open it up and the wind tunnel was partially clogged.
I really like this model of Hoover windtunnel...it has a very good Hepa bag that closes as you pull it off it’s mount and the exterior bag is very nice. It is also two speed and has a slow 3 second start up, some nice LED lighting, dual level bottom opening to prevent dirt from being flung out from under it, and some really nice styling. As a right handed user, I do find it odd though that the handle release is on the left side of the base. I think this model was designed to compete with the Oreck lightweight bagged upright...you know..the one we all think of when we hear the word Oreck...it is very similar in design.
The bags are quite pricey as a two pack is around $10 on amazon of genuine Hoover ones but also quite large but I could see if you have pets, the bag could get to getting a nasty smell before it’s truly filled to the full mark.
I believe this model has been discontinued unfortunately. Reviews showed some complaints with the handle breaking and some with issues with the electronics for the switching. I love the blue lighted switches though.
I have noticed that all of these windtunnels, including this platinum one...while well designed to pick up dirt, the wind tunnel section itself gets clogged with lint very quickly and there’s no way to know until you open it up, pull out the brush roll and the cover of the wind tunnel section itself and find the wind tunnel has been useless because it is stuffed with dirt! At least when that part is clogged it still functions like a non wind tunnel vacuum.
I’ll post a picture of the Hoover platinum windtunnel
