I bought this vacuum cleaner for one reason: I needed something I could use to clean the aviary with parrots in the spring and summer. They're making a huge mess on my deck screen and I thought it looked promising. The first assignment was right after arrival in early March and they didn't get a chance to make a mess. Everything worked fine for easy cleaning. Then the second use was only after the return window closed and it started clogging up like crazy. I kept having to bleed the hose and half the time it didn't work. If I leave it for a while it helps a little, but not always. We tried this to clean some wet spots in a concrete floored basement, mind you we didn't vacuum the rocks, the suction was even worse on wet spots. Tonight I decided to give the thing another chance in an aviary. The fastener connecting the nozzle to the stick broke so I sealed it with tape and everything was fine and then the suction stopped. Check for clogs, no. Restart it, run a bit, then it clogs. Rinse and repeat this 8 times and I still haven't cleaned the whole room. The damn thing goes in the trash. Bissel should be ashamed of charging so much money for such a useless piece of shit! I have been frustrated and frustrated with many products in the past, but how a vacuum company can vacuum clean crap is not to be commended. me. That has to be the biggest disappointment. I will never buy any product again.
