| Customer Reviews: Average Rating:  Rating : - Expect to spend around $20/month to use this vacuum. Unsure why Hoover went with this design. My old Fantom used its 'cyclonic' technology to get most dirt and small particles. The HEPA filter was only used for residual dirt; of which there was virtually none. In other words, the technology employed by the vacuum meant that the HEPA filter would not clog for years. It took over 8 years or so before the HEPA filter needed to be replaced. That being said, this Hoover uses the HEPA filter as a primary filter. It has *great* suction when new, but by the time I had to empty the canister for the first time, the HEPA filter was clogged! Now there isn't enough suction to spin the 'turbo/pet brush.' Point is, the HEPA filter should have been used only for *very* small particles, not as a primary filter. Anyone who has used HEPA filters knows that once the filter is clogged, cleaning it does not make it like new again. To get back to the way the vacuum worked new and out of the box, it appears that you need to replace the HEPA filter each time the canister becomes full. I have found the filters for sale at $10-20 each (add shipping/tax,) not a bad price, but consider that you will need to buy one at least once a month; probably more often. Some people have said they use cans of compressed air, and other methods to clean the HEPA filter. Not good enough, and it will not suck like new until you replace the filter. The stick vac on the other hand works great! Only use on hard surfaces, it's not meant for anytype of carpet. + See Full Customer Review |  |
