Rainbow
It has been said before, and it's very true about a Rainbow vacuum. They aren't for everyone! I have five of them (six if you count a parts machine) ranging from a Model B (small, black metal vacuum) all the way up to the newest model with the lighted basin. I have two of the D4 SE models which is very similar to yours (think early to mid 90's). If you suffer from allergies, they are truly wonderful machines. They don't blow dust out everywhere when you turn them on, there's no stinky bags or dirt cups to empty that inevitably belches dust in your face when you go to dump it out. Plus, I think it's really neat (in a strange way I suppose) to see all the "junk" you vacuum up off the floor floating around in that bowl of water......the newer Rainbows have a brushless motor that allows them to run continuously on low speed 24/7 if you wish. So even when you're not running it to vacuum your floors, it's "washing" the air in your home. Another good feature is that if you have young children running loose in your home, spills and messes are bound to happen. In fact, the last time I used the Rainbow, my young son turned an entire bottle of Gatorade over and poured it all over the living room floor. I didn't bat an eye, just turned the Rainbow around and sucked every drop of it up....no having to stop, grab paper towels, or a shop vac, no fear of damaging the motor in my vacuum, etc.
Now, with that said, getting back to my first statement, a Rainbow isn't something that you can just use, turn off, and stick back in the closet and forget about it until the next time it's needed (like you can with an Electrolux or other non-water vacuum). Each time you finish using the vacuum, you will need to dump the water out of the tank, scrub it good, and dry it. I also remove and clean the separator each time as well just in case. Also, Rexair (the parent company of Rainbow) is very specific that you are not supposed to store your water basin attached to your vacuum. So you have to make sure you have plenty of time after you finish to properly clean the vacuum and store it. I'm not trying to scare you off from these types of vacuums, but I do want to make you aware that Rainbows (all water vacuums really) require a bit more upkeep than your standard Electrolux, Kirby, Hoover, etc. [this post was last edited: 4/19/2018-08:26]
