Great model, it’s basically new !!
It was basically new. Everything was still sealed and in its original box and packaging. After using it for a few days it I can honestly say it’s been great at keeping the floors clean, I love it!!

Good quality and good value
Size: 2+6+1+12 Pack
this is a great deal and so nice to have on hand. I like being able to just grab replacement parts as needed and not have to place orders for them. It gives peace of mind to know I already have them on hand. much more affordable to buy all at once too
