Review on Enhanced Runtimes with Tineco Cordless Technology by Jenn Plata

. Everything seemed to work fine right away. Vacuumed the car and was impressed with the suction power. However, after about a minute, the device would no longer turn on. The battery appeared to be still charged, but plugged it into the charger anyway. Let it charge overnight and try again the next day, but it still worked intermittently for a few seconds. The engine failure warning light started flashing, so we brought it back.
