Eureka have been making these little vacuum cleaners for decades. I think I bought my first one sometime in the early 1990's. I've always had WiFi, but I'm glad I switched to wired. The wireless version is more convenient, but the weak point is the battery. Getting a decent battery, whether from Eureka or a reseller, isn't always easy. And of course the battery will drain over time. I managed to fix the batteries but they were never like new, just functional. But the suction power of a corded vacuum cleaner is much better than the cordless variant, even with a new and fully charged battery. This small vacuum cleaner is good for pet hair, cat litter and light dirt. It is very easy to clean carpet stairs with it as it is very light. It is designed to be used between uses of a large vacuum cleaner. However, you may find that this little person makes you less likely to use your big vacuum cleaner. As almost everyone said, the cable is too short. In my case, the 10ft extension makes it a lot more comfortable. However, the handles on the cord holder are too short to safely coil the extension cord when left connected to a regular cord. Eureka, please add a longer cord or add an extra inch to the cord holders to make this cleaner even better!
