Airflow is usually measured in Cubic Feet per Minute or CFM. It looks like the numbers you posted were from a Baird airflow meter which gives you a measurement which is a combination of CFM and watert lift on a proprietary scale of 1 to 10 units.
So if a vacuum has a rating of 4.5/10, it means it pulled a 4.5 out of a maximum 10 units on the Baird Meter which is just mediocre as far as vacuum performance goes. The Baird meter should be connected as close to the motor as possible because airflow decreases relative to the length of the hose. The Miele would be considered excellent at 9.5/10. FYI - There are very few vacuums that can pull a 10/10 on the Baird meter and Kirby is one of them because it has massive airflow compared to most other vacuums. |

Personally even if a vacuum cleaner has greater pull of suction, its the floor head design in question that can either inhibit pick up, get damaged itself or damage the floor it is cleaning.
If your tile floor is all in one tile, i.e a whole surface area of tile, I'd still be inclined to just use a hard floor brush rather than power nozzle. Unless of course the PN can be switched off and it has a sole plate that is void of any bare metal that could damage the hard floor in question. Conversely, a brush roll can pick up successfully on tiled floor, but in my experience the tiles need to sit flush. Tiled squares that have been fitted with sealant in between often provide a trundling experience with a PN and wheels, meaning not all dust will get sucked up in one pass. |

I have one of those meters, but their readings are not always completely consistent
When i had a Rainbow D4 SE it wouldn't register on the meter My Rainbow E2 (black) as you can see in the picture pulls about a 2 i have seen it register in at about a 2.5 as well. As for miele pulling a 9.5 maybe at the vacuum body itself but at the hose end the most i have ever seen a miele pull at the hose is a 5.5 both my older Silver moon and a newer S8 (forgot the exact model) can pull a 5.5 Is Rainbow the overall best? In my opinion no their airflow is mediocre compared to other door to door canister, and they are a lot of work to maintain i would much rather use a bagged system, i think the most powerful canister I've used is the Lindhaus Aria (reads in at 7.5 max) but i would not recommend one to most people as they are not as user friendly as some other machines. In terms of performance and convenience I'd take a Miele over a rainbow, but the rainbow is much more versatile, being able to pick up water, shampoo carpets (with the right attachments, etc. The newest model Rainbow should clean better i've never directly compared the two and no longer can as i parted with my D series models in favor of the E2 I think you should switch the powerhead for a bare floor tool when doing your hard surfaces.

Especially if you vacuum up dog hair. That is the beauty of the Rainbow. No bag, no dirty bagless container, all dirt down the drain, no smell, no mess. I haven't had a Miele personally, but my vac shop gets them in all of the time for repair. Replacement parts are very expensive. I have found that it can be difficult to get bad smells out of vacuums. It really depends on when you change your bag & filters, what you vacuum, and where you store it. Many Mieles have carbon-treated final filters to eliminate the smell.

I have owned both a high end Miele (model Capricorn) as well as the newest black model Rainbow. Although they are both good machines when it comes to sucking up the dirt, there are other factors to consider that influence how versatile and convenient the vac is to use. Some of the things I found were:
1. the cord on the Miele was far too short and I had to changed electrical outlets a couple of times whereas with the Rainbow I could use one outlet for the entire main floor of the house 2. the Miele's hose is shorter and too stiff. When vacuuming in tight corners it was always bumping into something with the possibility of knocking something over on a table 3. the wheels on the Miele are far too small if you are going to be using the vacuum on any type of rug with a medium to plush texture. I found the small wheels made it very difficult to manoeuvre. 4. the bags are expensive although they filter well especially compared to a Rainbow where you won't be buying bags 5. the above the floor tools (dusting brush, crevice tool, ulphostery nozzle) are miniature in size compared to those of the Rainbow. Also with the Rainbow you can get a motorized mini power nozzle for doing stairs, couches, car interiors, etc. compared to the Miele which only has a turbine powered mini nozzle. 6. the rainbow is a much heavier vac than the Miele 7. the Rainbow has the quick connect wands just like the Miele although the Miele's is telescopic. I bought my Rainbow new on Ebay and paid far less than what I would have paid from a Rainbow distributor. Gary |

I agree with those gripes on my Miele anyway, and I know it was not a high end one, however.... When the lower back is bad, it is light weight, has a soothing sound and pretty easy to live with. Bags are pricy, but very efficient in my mind, almost never need changing, very clean when you do.Give it a better hose and little longer cord and most my bitches are gone. I keep a short 4' extension on hand with it and can reach every room.No smell in mine even after months with same bag.
