HOOVER Anti-Twist Home HF910H Cordless Vacuum Cleaner-Grey and RedYou might have heard of no loss of suction', but what does that mean? It means this Hoover HF9 vacuum won't lose performance, even as the bin fills up with dirt. It has a powerful 4000 mAh battery and a 350 W brushless motor that give you enough time and power to clean the whole house. You can whip through the power levels with the fingertip control. And when you really need power, switch to Turbo mode that racks up the power to twice the normal mode.
