I just replaced an old Zing with this new one...the suction was still great, but some of the peripheral plastic was wearing out...the Zing is so inexpensive I opted for a new one, instead of buying replacement parts! I also have a Dyson ball, which is so heavy and awkward it hurts my back to use it...and costs so much more! You will have to spend money on the Zing bags, but it is so lightweight, powerful and easy to use, it is worth it!
