Summary: Gave 4 stars instead of 5 because I've only had vacuum for a short time. What I can say is I'm happy with it because I've always used an Electrolux canister and this Miele seems like old times at vacuuming - when my Electrolux died after many yrs.
I can live with the smaller head size (which actually works better for carpeted stairs) as long as the suction continues ...

Summary: I finally got tired of buying cheap vacuum cleaners and having them either break, smoke, or stop working in some way, and decided to look at more expensive models. After some research, I focused on Miele - this Delphi and another one (the next model up).
Summary: I finally caved in and purchased this vacuum after 2 other vacuum models failed to do the job. I can finally clean my rugs without the suction being too strong or wimpy and also clean the hardwood floor.
Summary: Super light works awesome. Have mostly hardwood with rugs and gets all our German shepherd hair up and her bone fragments left behind. -1 because we wish it had four wheels and you pretty much have to carry it but it's light not terrible.
Summary: Overall a good product. Happy with the cleaning and quietness, Stows away well. My concerns would extend to the balance of its use. The balance of the machine will recognize that the body will pitch and roll during use.
