Home improvement gear that promises quick, reliable water removal for emergency and routine drainage, introduced as the Einhell Submersible Dirty Water Pump. Peace of mind arrives when floods, hot tubs or ponds need emptying without delay. Is the build and feature set the right choice for regular or occasional use?

⚡ At a Glance
  • Suction Power: 900W motor delivers up to 18,000 L/h and copes with solids to 35 mm
  • Best for: Emptying hot tubs, ponds, excavations and flooded basements
  • Not ideal for: Tasks requiring filtration of solids larger than 35 mm

900W stainless steel submersible unit handles both clean and waste water with a maximum flow of 18,000 litres per hour. An adjustable float switch enables continuous run or level-controlled automatic operation.


Rapid drainage - Thanks to a 900W motor and 18,000 L/h flow rate

A high-quality 900W motor drives the impeller assembly to move up to 18,000 litres of water per hour, with internal clearances sized to pass solids up to 35 mm. The motor and hydraulics focus on delivering high volumetric flow rather than fine filtration.

Flooded basements, hot tubs and large drainage jobs clear much faster, reducing disruption and manual bailing. Faster removal also cuts drying time for affected areas.

Effective dirty-water handling - With 2-in-1 capability and 35 mm particle clearance

2-in-1 design supports both clean and waste water tasks by allowing larger particles through the impeller without immediate blockage, while the height-adjustable float switch controls start/stop points for automated use.

Suitable for ponds, excavations and construction runoff where debris is present, so frequent stopping to clear clogs is less likely. Level-controlled operation cuts down on supervision during unattended drainage.

Low-maintenance durability - With stainless steel housing and a high-grade mechanical seal

Stainless steel housing resists corrosion during repeated submersion, while a high-grade mechanical seal protects the motor from water ingress and reduces wear on moving parts.

Longer service life and fewer maintenance interventions should result, and registering the product extends warranty cover for added reassurance.
