Part of my reason for researching and buying this vacuum was visiting with some people in an RV Resort that wanted to compare the difference between the layout of my coach and theirs (we had the same manufacturer, model, and year (but theirs was 2' longer and the interior was a slightly different layout. When I went in their coach, the one thing that caught my attention was dog fur. It was in the corners, on the stairs, and I could see massive amounts in the cockpit area.I have one 25lb. dog that travels with me and he sheds. So when I got back in my coach, I ran my fingers across the carpet and was surprised to find fur. I was vacuuming twice per week, so I never expected to scrape a handful of fur out of my carpet with my fingers. I needed to find out why.I have a 40' coach that I bought as the second owner. It had an earlier model of this vacuum in it (Dirt Devil 950 model). I used it a few times and it was 'okay', but I had a beater brush that was brand new and when I tried it, the 950 could barely spin the beater bar - so I never used it. Then, I made a terrible discovery that turned out to be pretty dumb on my part - there was no catch bag in the vacuum! So the stuff I was vacuuming up was being blown through the motor and throughout the storage areas under my coach.Well, I put a vacuum bag in and the performance of the vacuum dropped dramatically. I went looking to see what to do. I pretty much was going to have to toss the old unit and go with the newer 9880 Dirt Devil. I ordered through Amazon and it arrived as expected.Installation: since I already had the 950 in place, installation was unfairly easy. Unmount the old, mount the new.First Use: OMG! This thing is amazing. The sound of the air being moved through it lets you know its potential. I hooked up my hose and a sweeper attachment and was amazed.Finger fur test: No sign of fur or hair on the carpet EVER.Beater Bar test: CRAZY GOOD. The beater bar is spinning at breakneck speed. Sounds like a supercharger on a big block engined car. This thing is turning as so high of RPMS that I worry that it might blow into pieces! It's truly awesome for hitting my carpets and the furniture.OVERALL IMPRESSIONS: It's great! Makes it fun to vacuum when you feel the suction that it has and you realize how productive it is to use. I can vacuum my whole coach (thoroughly) in about 7 minutes.I'm writing this review after having the 9880 for several weeks. It was a great investment to keep my coach clean and dog fur-free.ONE MORE THING: They upgraded the accessories that come with that come with this model. EXCELLENT telescoping pole and the hose is very heavy duty!
