In regards to cleaning up urine, if you are using kurr water, put water once on the place using a pipe and this will purify the area and if you have a wet vaccume, you can collect the water with that otherwise you can use a cloth to dry the area.

If you are using qaleel water, you can put water using a glass over the najis area, collect the water using a cloth or anything else available and then repeat. The cloth used to wipe the first water should be washed before using it to wipe the second water.
