My review is much different than the other folks on this thread. We purchased our Avalir as we needed a good, heavy duty vacuum cleaner to maintain our home.
It gets used in the main areas often throughout the week, and the whole house [5600 sq.ft] on Friday or Saturday. The vacuum is heavy but it does a wonderful job. Carpets, Tile and Harwood floors as well as stair cases, furniture, ceilings, etc. The tools that are included make any job possible and the vacuum really does make things very clean.
You need to understand how to use the machine and the features to benefit from all of the uses it was designed to perform. It does not take long to change out the unit to use accessories or to convert back to the full upright. We did not buy our machine for convenience - we bought our Avalir for a heavy duty cleaning performance. It doesn't need to look modern or sleek.
It vacuums everything - that's what we expect and appreciate about the Kirby. The sale person was not the best but I stayed in control, kept the demo moving along and was quit frank about what I was willing to pay, even before the the demo started. We were finished in an hour, and sale was over. If you want a machine that does an excellent job, and will last for may years than the Kirby just may be for you.
If you need convenience and modern style, well maybe you need to look somewhere else. I bought our vacuum to clean, nothing more.
