I have the corded duo clean true pet model.
I loved it at first but it just seems to pick the bits up and keep them swirling round, then when I lift it off the ground it spits all the bits back out!
I've emptied it and everything there are no blockages. Is it just mine!?
It seems to work better on my thicker carpet, thinner carpet or hard floors it's crap and does the spitting out thing! Argh
