I did a job yesterday, o.k not a rug, and was just doing the pre-vac with Sebo and doing around the door and edges when suddenly about two inches of carpet just disintegrated and disappeared into the vacuum at both sides of the door. I was left with one large hole of 2" on one side of the door and a 1" hole on the other. Was really panicking about what to do and in the end came clean with the owner who said the previous owner had a hamster who a chewed up the the area's and the previous tennant had tried to disguise it by just putting the fluff back in the holes, hadn't even bothered to glue it, the landlord had already found out, so luckily i was off the hook.
