My V7 pulses, ie goes on and off, when I use the long attachment but is fine with the hand tool. Ive replaced the filters and can’t find any blockages. It may be the battery but I’m reluctant to spend more money when it might not help, as the vacuum is only two years old.
I waited for ages in the queue and spoke to a guy who wasn’t helpful or interested. The machine is only a couple of months out of warranty and I expect more from such a premium brand. Any advice before I switch to a more reliable brand?
