Real-world cleaning in Northern Indiana – the kind of work Water Storm pressure washers are built for every day.

Ergonomic Handles & Anti-Walk Stability

Anyone who has run a chattering, walking pressure washer knows how annoying it is to chase your machine across the driveway. Water Storm tackles that problem with frame geometry, shock-absorbing feet, and a comfortable handle design.

Water Storm pressure washer handle and frame at Miller Power LLC
Handle and frame of a Water Storm pressure washer – light enough to move easily, heavy enough to stay planted while running.
  • Dual shock-absorbing feet dampen vibration and reduce walking.
  • Handle geometry is designed around the unit’s balance point for easier loading.
  • Flat-free tires roll smoothly over gravel, shop floors, and job-site terrain.
  • Weld-free aluminum design keeps weight down without sacrificing strength.

The goal is simple: when the pump is running, you’re focused on the wand, not wrestling the machine behind you.

Which Water Storm Pressure Washer Is Right for You?

If you’re not sure what PSI and GPM you really need, you’re not alone. We help homeowners, farmers, and contractors match the right machine to their work every week.

  • Homeowners – MP3027HV or MP3032HV usually offers plenty of power.
  • Farms & shops – MP3032HV or MP4042HV handle equipment, trailers, and concrete.
  • Full-time contractors – MP4042HV, MP4042HVE, or MP4042HC paired with surface cleaners and hoses.
  • Harsh / corrosive environments – SS4040ARH with its stainless build.

Tell us what you’re cleaning, how often, what your water source looks like, and if you plan to run surface cleaners. We’ll point you to the best fit instead of overselling you.

Ready to talk it through? Call (260) 768-7002 or send us a message.

Can I run a surface cleaner with these machines?
Yes. The 4 GPM units (MP4042HV, MP4042HVE, MP4042HC, SS4040ARH) pair especially well with surface cleaners for driveways, patios, and parking lots. See our surface cleaner page for options.
Do you help with setup and first-time use?
Absolutely. When you pick up a unit from Topeka, we can walk you through startup, choke settings, fuel and oil, and basic maintenance so your Water Storm is ready from day one.
Can you ship to my shop or farm?
Yes. As long as you have a business address and a loading dock or lift, you qualify for our listed flat-rate freight pricing. If not, we can still ship – we’ll just price out the best option for your area.
Do you service what you sell?
Miller Power LLC repairs pressure washers and can help with pumps, hoses, unloader valves, and more. When you buy from us, you have a real shop to call – not just an online checkout.
