What innovations have made Vacuum Cleaners clean better and what are the best examples of these?

i dont think it is possible for any vacuum to loose suction. i do know that after vacuuming a litle, the vacuum looses airflow. and there isnt a vacuum in the world that doesnt loose airflow. i cant think of anything that i can compare this to but they have made it as if the the most important part of a vacuum is the suction when it is actually the airflow. it is the suction that maintains the airflow though.

Vacu-Finder--which Oreck Power nozzle for Central Vacs?

You mention that the Oreck power nozzles for central vacs are great. Are you perhaps referencing the Allegro Smart power nozzle that has styling on the hood resembling a hybrid mixture of Hoover Windtunnel and Quadraflex power nozzles? See link.

Filtration is key

I think the improvement in filtration is a key area of improvement. No matter how powerful a vacuum cleaner is, with poor filtration you get a poor cleaning result as all the expelled dust settles again.

One of my earliest vacuum memories is of my mother's Hoover Junior from the early 80s which worked OK (the edge cleaning was particularly impressive) but the top of the motor housing was always covered in fine dust that leaked from the bag.

When that died it was replaced with a Miele S280i which was from the first set of Mieles to have the Air Clean filter which was a big improvement. It always used to gross me out that the filter was white when it went in and after five bag changes was nearly totally black.

I was cleaning with my Miele S6 tonight. Big spillage of coffee powder on the kitchen floor. A real waste of instant coffee which some may well disagree isn't a waste. However totally dismayed to find the AAC filter does not absorb the smell of coffee. Shame when it does so well with pet hair and tobacco though. Still, I don't mind the smell of coffee emanating from the Miele each time I clean now lol.

I vote for....

Kirby's toe touch control, tech drive and belt lifter. I also agree with the people that say filtration, which brings me to the Rainbow. Anyone with allergies should have a Rainbow. Wet dust does not fly. Rainbows with or without a hepa filter as long as you don't pick up non wettable particles, will greatly improve your allergies as well as less dust that settles on furniture after vacuuming.

Actually Bud, that reminds me, it may sound obvious but one of the things that used to set m Aunt off with her allergies was the use of furniture spray. They can be quite toxic smelling those sprays. Pledge is the worst (J&J company) - she can't stand the stuff when I use it. I wet damp cloth shelves - best way of getting the dust off if I can't be bothered to vacuum.

Ryan,

Yeah, that coffee aroma is not so bad. I had a similar thing happen, however, with some material that had a strong dog smell to it. I was dismayed that the smell seemed pass right through the new HEPA filter that I had on the vacuum.

It made me wonder how small odor particles are that they can get through a HEPA filter so easily. Of course, it may just point out that HEPA filters do not really filter as advertised, or that the airflow in the vacuum was leaky.

It was a Eureka Mity Mite, which has a super simple airpath, so I doubt the smell was bypassing the sealed HEPA gasket in the back. Makes me think either the HEPA filter was not doing its job, or that odor particles are small enough to get through.

I was disappointed to say the least. I really hate that wet dog smell.

Good point. Not all HEPA filters are thus the same.

It reminds me of my old Hoover Telios cylinder vac. It used to have the option of a HEPA cartridge that slid in behind the dust bag to where the motor was located, not on top of the exhaust filter at the top of the vacuum. Did the job well but it also cut off the suction pretty drastically, and though it did this, the amount of pet hair odour in the bag seemed to be contained in the bag and no where else. The problem was the lack of power with the HEPA filter slid in place compared to the thinner tab. Hoover eventually replaced the Telios range with the Sensory where they moved the HEPA filter right on top of the exhaust filter to maintain suction and filtration and though it did a similar job, it wasn't as effective in terms of sealing bad odours in.

Hoover eventually improved the problem by designing a newly improved "Pure Filt" high filtration dust bag.

What about the Embedded Dirt Finder?

I vote for 2-stage, clean fan motors, or as Electrolux UK used to say, "twin fan".

Twin fans, in-line on the same motor shaft increase the suction efficiency of the motor. No need for 1800 Watt motors - around about 1000 Watts is quite sufficient.

With the crazy energy prices these days, we need efficient machines now.

Vacu-Finder--which Oreck Power nozzle for Central Vacs?

Durango159,

I'm referring to the older type P/N...They were very reliable and did a great job for the central vacs.

In my opinion, Hoover really improved the Convertible in the 1970s when they introduced the Type A bag and the front conversion attachment set. Does anybody agree with me?
