I have been told a number of times by various people who should know that the cheap pressure washers are designed for a life of about 10 hours. Which does not sound much but as most are used for a max of 15 minutes occasionally they can last for at least a couple of years and therefore be out of warrantee.
I have had a couple of B&D drills in the dim and distant past (> 50 years ago) and they were OK if you treated them gently. My father burnt out a new one while using the saw attachment. I had two Bosch drills about 45 years ago, the first one broke in a week and was replaced under warrantee, the second worked for many years and had a very very hard life, I eventually chucked it out when the play on the front bearings was very excessive.
I broke the gear change yoke on my more recent battery Makita drill after a couple years of business use, a replacement required a complete new gear box despite it being a simple bit of plastic that had broken so I sold it cheap to to a mate as a single speed drill.
What I have noticed though is that drill bits make a fantastic difference. A customer was helping me by drilling holes in a concrete panel, he had a decent battery drill and was struggling, I gave him one of my Bosch masonry drill bits and he was no longer struggling
