Keep your Rover HVE Rovin’
A little proactive maintenance can go a long way to keep your Dri-Eaz Rover High Volume Extractor in top operating condition. There are components you should inspect regularly, and others should be checked every six months or yearly. When performing any maintenance, start with safety in mind – unplug the unit and be careful of pinch points and sharp edges that might cut hands and fingers.
On a regular basis 
Before each use (monthly at a minimum), inspect the electrical cord and plug for damage and repair or replace it, if needed. Check the extraction edges of the polymer glide for sharp edges or burrs. These can potentially catch and unravel carpet fibers. If you find damage on the polymer glide, replace it. You also want to inspect the stainless extractor head for burrs or dings. For minor burrs or roughened edges, carefully sand or file the metal lightly to smooth it down.
Always check the polymer glide holes to be sure they aren’t clogged or damaged with gunk, carpet fiber, pet hair, large pebbles, etc. Clogged holes reduce suction and that reduces extraction performance. If you are on a job and discover an obstructed hole, try using a wire to dislodge it.
Every six months
Check the wheel drive components. They’re visible from the bottom of the unit. Look for corrosion, oil residue, misalignment, obstructions, etc. After 1–2 years or 1200–1500 hours of use, whichever comes first, it’s probably time to think about replacing the drive motors. Note that there are two drive motors–one for each drive wheel. 
Keeping your Rover Clean
 Wipe the base with soap and water, including the cover and the insides of the extraction head and the hose connection. Be careful not to allow water into the control box or motors. Water can seep in through the mounting holes for the switches – it’s best to carefully wipe these areas clean. For the rotomolded parts of the unit, products intended for automotive vinyl cleaning and protectant products work well.
