My partner just did the SAME operation on our Shork vacuum cleaner due to steadily declining performance. The ultimate diagnosis is the brush head has lost its brushes. They don’t sell a replacement, but they do sell an entire power head replacement for $99. Fuck these guys, we’ll never buy a Shark again.
Definitely do not buy Shark products. They used to be good, but maintaining any of their stuff now feels like it was intentionally designed to rip you off.
I have their old vacuum cleaner that I’ve repaired five times and I’m never getting rid of it.
I gotta find me one of those. Mine was a gift from my mother and I am not looking a gift horse in the mouth in this economy. It’s a bit of a pain, but I’m good with my hands and even better with pulling apart tech. It’s a pain, but not impossible to clean.
Bonus is that you can buy third party roller replacements for a third of the price of the head unit. At least third party markets are still allowed for the time being.
