KärcherSP 9.500 Dirt Submersible Pump, Flow Rate: 9,500 l/h, Depth of Immersion: max. 7m, for Dirty Water with Particles up to 20mm in Diameter, Residual Water Height: 25mm, Pressure: 0.6 bar

Used to quickly drain the hot tub, fast, quiet, only leaves a little water in the bottom when the float switch turns it off.

This pump is very effective in removing water. I have an issue with groundwater seeping in under my floor. I have installed this and it quickly pumps the water out. Easy to install, well made. Good value for money.

Used to do partial water change in my pond and works great 200 gallons in 35 40 mins

I bought this to drain my waterlogged back garden. I did not realise that the automatic on/off function via the float switch requires about half a metre depth of water. This means I had to use it on manual and stand and watch it so it did not run dry. That said though it is very effective and can lower the water level down to just around its base ( on manual). In the event I bought another one with an internal float switch so I could leave it to itself. But if you have deep water this is good.

Reliable but does not drain sump to the same depth as the old one. However it is the best there is now.

Used pump on a timer for garden feature pond waterfall. Product has stopped working within 2 months.

Really powerful pump but needs the separate Karcher hose to get full efficiency. Won’t however pump out every inch of water as it needs min 2” (5cm) depth to be able to work.

Absolutely brilliant for pumping water out of sub-floor in our house. Used in manual mode as it was easier. I would recommend the pump to anyone. Cleared a lot of water in a short amount of time down to a minimal level. 10/10
