My first cordless vacuum was a Hoover Linx. It was a nifty little vacuum that was easy to grab to do a quick cleanup. I could give the whole condo a quick touchup without emptying the dust cup. I especially liked the removable battery that could be charged discretely. No need to have the vacuum standing out in the open next to an outlet to charge. I also have a full size Dyson, but sometimes you just don't need the big guns. Plus I have a lady that comes to clean every other week.After six years of service, the bottom floor piece broke off the upright. Apparently, that was the Linx's weakness. I was ready to order another one, but it was discontinued. I ended up with one of those multifunction Dyson lookalikes, because it had a removable battery. Among its multifunctions, it did nothing well. It wouldn't touch my German Shepherd's hair. I have a nice hand vac, so I didn't need that. When I vacuumed, all the extra tools kept falling off the handle, until I ended up throwing them out. I couldn't even finish one room without having to stop and empty the tiny dust cup. The center of gravity, motor and battery, was up at the handle making it awkward and when you're old, a bit tiring to handle. I finally had enough, and sent it to that great broom closet in the sky.This time, I ordered the Hoover Evolve Pet Elite and I've been very happy with it. It has everything I like, removable battery for charging, large dust cup, low center of gravity so the floor carries most of the weight, nimble and easy to grab for touchups. It's like my good old Linx only better and more powerful. This one even gets the dog hair off the Persians.And I have learned a lesson. Having a tool that does one thing well can be better than one that does several things poorly.
