I first discovered Vacuums R Us when I needed a part for my SEBO E3. When I found the part I believed that I needed on their website, I called and the gentleman was very helpful in diagnosing the problem over the phone. He sent the part and solved the problem. When I received an email about their 20% off SEBO sale, I decided it was time to get a D4 (even though the E3 is still going strong). I called with some questions and, again, received great assistance in ordering the vacuum and extra accessories. Even 1400 miles away and sight unseen, I get the best help from Vacuums R Us!
