Turn any portable extractor into an incredible tile and grout machine with the Water Otter! The worlds #1 best selling carpet and tile cleaning pump. This is the same pump installed under the hood of 90% of the tile cleaning machines on the market today. By hooking your pressure hose to the Water Otter instead of your portable extractor, you'll get 1200 psi of raw power to blast grout lines clean! Now you just need to hook your vac hose to your portable extractor, and put on a good tile and grout tool (SX-12 or Gekko come to mind) and you're ready to clean tile with the best! Clean at 500 psi for carpet cleaning or turn it down to 200 psi for upholstery cleaning.
