1. VERY BAD DESIGN: The hoses have numerous joints where the coupling ridge is reversed from how it should join - meaning that the ridge faces towards the incoming flow so as you can imagine any object large than a dust particle will hang on the ridges (three of them from nozzle to tank) and it clogs CONSTANTLY. There is no other tank vacuum on the market that has this poor design so buy one of them. Oh, and this hose has a couplings like NO other manufacturer so you can't just swap hoses. 2. The air flow is TERRIBLE. I have a Shop-Vac 5hp peak and the suction power is awesome. However this Vacmaster unit has less suction than my (near dead) DustBuster - matter of fact it has nearly zero suction. Don't buy this if you want to vacuum anything other than feathers and Don't plan on using the extension hose because when you add that on the suction dies to a point it won't even pick up dust. 3. NO CAPACITY in the tank. Other companies have this issue too, but it is no excuse. The entire 5 gallon capacity is wasted with an HUGE filter (which by the way is outrageously priced to replace so be prepared for that also). A friend of mine that is an engieer estimated that this actually has less than 1.5 gallon capacity with the filter installed (and of course you cannot vac without a filter now can you!). 4. Yeah, the remote control handle is cool, but the product is junk. Go buy yourself a Shop Vac for half the price and deal with shutting it on/off at the tank. You will be much happier. I sooo regret buying this piece of junk and I am so mad that a company would sell something with such a bad design for ANY PRICE! This thing is going in my garage sale for a huge loss now. Don't be the next victim.
