This shop vac has very good suction but the fact that it is half the weight of the 20 yr old sears that just quit worries me on the quality. It has a 11.8 amp motor which if you know anything about electric motors is a true 1.9 hp which is good.. I don't know why there is not a law against the peak hp ratings on vacs and air compressors. It means nothing. Always look at the amps. It takes 746 watts to make one hp. ie 1 A X 120 V = 120 watts.
It really sucks (in a good way), perfect size, enough accessories but the design for the lid is so bad. You can't really lock it. Dust is everywhere. While in LOCKED, if you hold the handle and lift it up, there is about 1/4" gap between the lid and the base. I used it ONE time and it will go back.
Bought this vacuum cause I needed a good shop vac for dust collect and car detailing. Have used it extensively over the last 10 days with out a hiccup. Extremely powerful when used with my dust separator or vacuuming wet carpet. Great vacuum.
