I did it. Yesterday I bought a Roomba, but .....

... a little bit of the 'remove filter by pressing these yellow bits' fell off. I'm not sure it wasn't my fault.

Do I put up with it, or take it back to Lakeland? In fact, I'm sure it was my fault. What would you do?

Don't think I've ever killed my own thread before .....

Phone Lakeland - in my experience they have excellent customer service and will sort it. Just say it fell off, as it did - it has to be built to withstand reasonable amounts of wear and tear, and unless the bits fell off after being flung out of a window or something, then you haven't done anything wrong..

I have heard that the Roomba people are also very good at customer service, so might be worth contacting them if you have no joy from Lakeland.
Are you sure it is broken - they do have lots of fiddly bits?

It's definantely broken - a little yellow bit snapped off. My conscience is bothering me a lot - it cost quite a lot, yet I'm certain the thing that went wrong was due to my own ineptitude.

I dont think you should feel bad about this, either the roomba isnt robust enough or the instructions werent good enough!
