I just answered this easlier so maybe you can look around and read but my husband and i have been breeders/show our Chinese shar-pei for 19 years and the best i have found is a Bissell V. versus.
Its shaped like a V which is great for getting the corners of walls, furniture. Go to www.bissell.com and look for that black with the V bottom i paid 60.00 when i bout mine. My vet saw mine she loved it and bought 3 for her business. I might just go and buy another one incase they close up shop or close down. You wont be dissapointed i promise. Good luck
