this guide is to share some of our experiences of using the h2o vac turbo versus other vacuums I've used. (the below is just my own opinion)
I have used many different kinds of vacuums: rainbow, tri-star, etc and this h2o vac turbo is, in my opinion, one of the best. First, I'll say a few things about the rainbow and tristar, which are very good vacuums.
one good thing about the rainbow is that you don't have to worry about dust when you empty the receptacle because all the dust and other junk gets trapped in the water and it provides good continuous suction. what's bad about it is that the vacuum blows out dusty air and you have to clean the little motor cover attachment after each use, because if you don't one day it will break (we've had it break before).
The tristar does not use water so you have to deal with dust when you empty out the receptacle. one good thing about it is that the air that comes out of the vacuum goes thru a filter so the air isn't very dusty and is has good continuous suction.
The H2O Vac Turbo on the other hand, is like a combination of both the above mentioned vacuums. it uses water so that you can easily dump the junk outside and it has a hepa filter, so the air that comes out isn't dusty. when we first used it, I was amazed that our air filter (senstive to the content of dust in the air) didn't go on high speed as it usually does when we used the rainbow. and the air didn't smell dusty either. I also like the adjustible suction levels ( I like to use it on the 3rd level). the h2o vac turbo is light compared to both our rainbow and tristar (both older models) so it is easier to haul around. plus you don't have to worry about the rolling up cord because it has a retractable cord, but I think the cord is shorter than the other vacuums.
the h2o vac turbo is fairly easy to clean. I just use the front yard garden hose to flush out the junk in the container. plus you don't have to put a lot of water in the container. unlike our rainbow that needs much more water (but I guess you could go a lot longer without changing the water).
when I saw the infomercial I wasn't really that impressed until I saw you could use it was an inflator/air blower. I haven't used that function yet, so I can't say if that really works or not.
I used the h2o vac turbo today to vacuum the staircase (has carpet and wood ) and I used the brush attachment and the standard vacuum head and it did a really good job.
I wish the cord was a bit longer and the standard head brush was sturdier (thinking about getting the optional Power Head for deeper carpet suction). the "air flow chamber" that goes over the water tank can be hard to remove at times. Overall good, lightweight, vacuum. Price wise, there's no comparison. I think it will replace my other vacuums...
