I still do not see the point.
If you want to do an area bigger than a postage stamp you will need a hose.
A bucket of water would only last about 30 seconds (I have had one for 30 years).
And how many people have a river or a lake they can take water from, and even if they do, they still need a hose from their lake.
You get a hose in with it. You NEED a hose, to get the water. The 20 minutes battery life put me right off. That will be on the lowest possible setting so, wo betide anyone blasting, or using it on a higher setting, you will get approx 7 minutes.
There is no way I could do all of my land in that time. Waste of money.��
