Our vacuum hose attachment wasn't working, I use this often to pick up lots of kid dirt and dust the baseboards.
We have a nice vacuum from a local dealer, but the last time I took it in it was $35 and they fixed it, but still. I took it apart, just a few screws and found a long Lego stuck in the U joint that made a huge clog, took it out and bam works perfectly, saved not only $35 but the time it takes to take it in and wait a week for them to fix it.
