We Tried the New Hoover Onepwr SmartWash Cordless Carpet Cleaner 

Theoretically, if you have a few extra batteries charged at all times, you can have a carpet cleaner with a limitless run time. Not having to worry about cleaning too far from a power outlet to keep your carpet cleaner plugged in is helpful too. The question is: Does this cordless carpet cleaner deliver on cleaning? 

We purchased a Hoover Onepwr SmartWash Cordless Carpet Cleaner to try for ourselves. In our labs, we evaluated the cordless carpet cleaner using an amended version of our formal carpet cleaner testing. After one round of our carpet cleaning and water retention tests plus several hours of poking and prodding, I have some thoughts.
