Stihl RB 400 vs RB 200 - The Differences

Further down the page, you'll find some explanations regarding the key similarities and differences between the Stihl RB 200 and the Stihl RB 400.

But before checking out explanations regarding their power, design, and features here's a table that summarizes the main pros of each of these 2 pressure washers:

Stihl RB 200Stihl RB 400
Stihl RB 200Stihl RB 400
  • Lighter
  • Higher PSI
  • Higher GPM
  • Higher Cleaning Units
  • More nozzles
As the RB 200 and the RB 400 are both Stihl pressure washers, they benefit from the same level of quality and attention to detail.

Power Comparison

  • Fuel: Both units are gas-powered pressure washers.
  • Engine & Pump: The Stihl RB 200 and the Stihl RB 400 both use an axial-type pump to put water under pressure. The pump on the Stihl RB 200 is powered by a 173 cc engine, while the Stihl RB 400 uses a 196 cc engine. Both devices use a conventional pull-start mechanism to operate.

The following charts are provided to show you at a glance how the main specs of the Stihl RB 200 compare to the Stihl RB 400.

  • Pressure: With a maximum reachable pressure of 2700 PSI, the Stihl RB 400 provides a slightly higher force to blast off dirt and grime than the 2500 PSI of the Stihl RB 200.
  • Water Flow: When operating at low pressure, the RB 400 can generate a much higher maximum volume of water than the RB 200. It can deliver up to 2.7 GPM (gallons per minute), whereas the RB 200 offers a maximum water flow of 2.3 GPM. The former should thus allow you to rinse away dirt and debris with significantly better efficiency and speed.
  • Cleaning Power: With its 7290 C.U. (Cleaning Units = PSI x GPM), the RB 400 offers a much higher overall cleaning efficiency than the Stihl RB 200 and its 5750 C.U.

Design Comparison

  • Design: Both units are constructed with a hand truck design. Therefore, if either of these 2 devices should provide better mobility, it would be due to its wheels and weight (which we detail just below).
  • Weight: Weighing 62.5 lbs, the RB 200 is far lighter than the 90 lbs of the RB 400.
  • Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. Both offer a folding handle, which improves your grip when you wish to move them.

Feature Comparison

  • Soap Addition: Both washers allow for the addition of chemical detergent solutions to the water. In both cases, this is done via a siphon hose.
  • Trigger Gun & Wand: Each of these 2 units comes with a fairly standard ergonomic trigger gun and a classic wand.
  • Nozzles: Both pressure washers come with 15°, 25°, and soap nozzles, but the nozzle similarities stop here. The RB 400 also has 0° and 40° nozzles.
  • Reach: Both products include a 25 ft high-pressure hose. Therefore, neither of them will, out of the box, allow for a higher freedom of movement around the unit.
  • Storage: The RB 200 and RB 400 both offer onboard storage that allows you to neatly keep the accessories you need at hand. Both washers feature a set of hooks to help you neatly store their high pressure hoses when not in use.
