Fitment Notes
- Always verify the OE part number stamped on your existing water pump before ordering. Fitment data is provided as a guide and may not cover every sub-variant.
- This is the 3-hole thermostat cover variant. Some N47D20 applications use a different thermostat cover configuration — count the holes on your existing pump to confirm.
- The N47D20A and N47D20C are variants of the same engine family and share this water pump.
Installation / Use / Maintenance Tips
- Drain the cooling system completely before removing the old water pump to minimise coolant loss and contamination.
- Clean all gasket mating surfaces thoroughly — do not reuse old gaskets or seals.
- Inspect the thermostat, radiator hoses and drive belt while the pump is accessible; replace any worn components at the same time.
- Refill with BMW-approved coolant and bleed all air from the system before starting the engine.
- Run the engine to operating temperature and check for leaks around the pump housing, hose connections and bleed points.
Common Questions
- Will this water pump fit my vehicle?
- Check the fitment table above and confirm the OE reference number matches the one on your current water pump. If your vehicle and engine code appear in the table and the OE number matches, this pump is a direct fit. Also confirm the 3-hole thermostat cover matches your existing pump.
- What do the OEM reference numbers mean?
- OEM (Original Equipment Manufacturer) reference numbers are the part numbers assigned by the vehicle manufacturer. They let you cross-reference this aftermarket part against the original to confirm compatibility.
- Is Partquip the same as MAP Pro?
- No. Partquip is an independent aftermarket brand. MAP Pro is the house brand of Modern Auto Parts. Both are available in our store, but they are separate brands with their own product lines.

Fits but not great quality
Style: for Saros 10R / Saros 20 / Qrevo CurvX, Style: for Saros 10R / Saros 20 / Qrevo CurvX
I ordered these hoping that they would work in my Saros 10R but I didn't have the greatest experience. It's a nice kit because it has everything you need while the company hasn't fully released all replacement parts yet. However, it seems like the quality is lacking compared to what came with the vacuum.
When I got the kit, I replaced the mop pads, filter in vacuum, side brushes and main rollers. The mop pads are fine and seem to work as good as stock. They are the right size and I don't have any issues with them. The side brushes also seem mostly the same as stock. However, I ran into issues with the filter and the rollers.
I'm including pictures of the filter after one week of use compared to the stock one that has had almost two months of use. It seems like the replacement filter was easily clogged up, whereas the original after two months was clogged in one area. On the back side of the filter, it seemed like the replacement filter was puffy whereas the original was crisp. Even after knocking the replacement around, it seemed like the dust was glued to the filter. These pictures were also taken after the dock "emptied" the vacuum.
I also noticed that when I replaced the rollers, the vacuum made a noise like something was rattling around. I put the original rollers back on and the noise stopped. Tried one more time and it made the rattle. So I just ended up using the stock rollers.
The kit is nice because it has all the parts you need to maintain the vacuum. However, my experience is that it doesn't work as nice as the originals and I ended up going back with the original manufacturer parts.

Get yourself a spare set of mop cloths to keep your Roborock always ready to run
Size: Mop Cloth-5
Does the Roborock do a fantastic job mopping the floor? No, but it does a pretty good job, in fact “good enough.” Even better, the Roborock mops the floor more frequently than I ever did so it stays cleaner, overall.
Definitely get a pack of spare mop cloths so you can have a set being washed while another set is available to put on the mop.
So far, none of the mop cloths have worn out. Given how long they’re lasting, I’m inclined to say it is a decent value for the price paid.

OEM Roborock Cleaning Pads - Do not buy the knock offs.
Size: Mop Cloth-4
These are Roborock OEM pads for my 10R. I tried many of the cheap knock offs and they were terrible. These work great. Highly recommend.
