This is the ultimate vacuum! It runs on a lithium battery that is rechargeable but never loses power even if the battery is low. Doesn't leave a crumb behind. Works well on tile, hard wood and carpet (area rugs too). It is a must have with pets and kids. In fact, my kids ask to vacuum.
No cordless vacuum from any other brand matches the cleaning performance of the V6; in our tests, it picked up more ground-in dust and hair from our carpets than any competitor and cleaned up bare floors in fewer passes.
