Rainbow Vacuum
Reddit take
AI summary of the Reddit excerpts below — not a quote
Rainbow vacuums are highly polarizing water-filtration systems known for exceptional H13-level air filtration but criticized for their high cost and demanding maintenance. While some users swear by their ability to trap dust and odors in water, others find them cumbersome, heavy, and overpriced compared to modern high-end canister vacuums.
Pros
- Excellent H13-level sealed system filtration
- Uses water to trap dust and odors effectively
- Can function as an air purifier
- Professional repairability and long-term durability
Cons
- Extremely high price point (mentions of up to $3,000)
- High maintenance: water basin must be cleaned after every use to avoid mold or odors
- Heavy and difficult to maneuver or store
- Reported lower airflow and suction relative to its high price
Caveats
- The water basin requires immediate cleaning to prevent contamination of the motor
- Users report that while the filtration is superior, the actual usability is often described as 'awful' due to the weight and setup
Best for
- Users with severe allergies or breathing problems
- Those who prefer water-based filtration over bags or bins
- People looking for a vacuum that doubles as a home air purifier
Avoid if
- You want a quick, low-maintenance cleaning experience
- You have a limited budget
- You struggle with heavy appliances or have limited storage space

Why are you the first person to mention the rainbow comment? Those things are AWFUL.
Rainbow and Miele are the best filtering vacs available since they produce sealed-system H13 vacs.
they’re both very high quality machines and don’t cost $3,000 like a Rainbow does.
Miele and Rainbow both produce H13+ vacs.
I’ve read that the rainbow, although seemingly superior, is tough to clean
Rainbow is the worst
The Rainbow uses Mother Nature’s most powerful element, water, to trap dirt and odors, returning only naturally clean, water-washed air to your home environment.
Say your Kirby or Rainbow breaks, you can have a professional fix it.
