Small space dwellers

The classic user
This has been around for a while because it works. It is a no-nonsense vacuum that understands the assignment.
Multi-surface homes
A solid mid-range option that balances power and ease of use. It is a reliable tool for any kitchen or living room.
When you look at these machines, you have to decide if you want a simple tool or a smart one. The NV501 and NV752 have been the reliable staples of many homes for years, and for good reason. They do not have all the fancy sensors of the newer AZ4002, but they have the suction power that made Shark a household name in the first place.
On the other hand, the Stratos and PowerDetect models are for folks who want the latest bells and whistles. The PowerDetect actually senses what floor it is on and adjusts the brushroll speed. It is like having a vacuum that went to college, whereas the older Rotators are like a sturdy tractor that just keeps on plowing.
Don't get distracted by the shiny marketing. A vacuum is only as good as its ability to hold up when you are tackling a house full of pet hair and dirt. Durability and maintenance are what count. Look for models with washable filters and easy-empty cups, because if it is a headache to clean, you simply won't do it. The Stratos and Rotator lines generally offer that nice balance of being easy to maintain while still being tough enough to handle a weekly beating.
If you want the best performance available today, go for the PowerDetect AZ4002. It is the most capable machine in the bunch. However, for a hardworking family that wants to save a few dollars without sacrificing performance, the Stratos AZ3002 is the best value pick you can make.
