Something That Sucks
Jen and I have been using a Dyson DC-15 Animal ever since we got an apartment together in 2007, and it has been showing its age for a while. The brush driver was extremely hard to turn by hand, it frequently left things behind, and one it has always emitted a high pitched tone that drove me to don firing-range hearing protection.
I’d recently disassembled the agitation brush system to clean out a bunch of cat hair and dust that had caked itself into the gear assembly that drives the agitator.
