Hmmmmm,
I want it but not sure what I need it for. 🤔 Maybe the fish tank and flushing my water heater?

Especially good HD deal via military exchange sites for $180 w/free shipping, considering 2x 5.0Ah batteries are typically $60/each. So effectively ~$60 for the pump.

I bought one with the 2 5.0 batteries a few years ago for this price thinking the same thing. I can't believe how often I end up using this thing.

If you have the cash, and think of each of the 5.0 batteries at $50 each, and the tool at $100, it's a good deal.

I have no need for this at the moment but I've always kinda wanted this but could never justify the cost. It comes with 2 of the 5ah high outputs which I can easily sell for $75 each in my area. Charger sells for $15. Makes my total cost for the pump at $48. Good deal in my opinion.

You don't need it. Water heaters can be flushed without any sort of pump. You just open the valve and let your water pressure do the job.

Fish tank? Learn how to use siphons.

You know about the battery part, I was just thinking about that looking out my windows. Cost X2 HO 5.0 and $100 further for the pump.

I'm going to get one. Can pump out my kayak if water gets inside, water shut off switch at the street, water not going down the drain so needs snaking, water pooling in some random trench I'm digging, creating a sand castle moat (Need a very long hose to fill the moat), looks like i could water the garden from 5 gallon HD Buckets, pump out a flooded basement (happen once), some guy hacked it with Franco coupling to pump out waterheaters, pump out trash can for ice shock,

Just some random ideas that came to mind for this pump.

Mine has been a real life saver when my sump pump went out. Also very useful for clearing out holes after a night of rain - used it when I was putting in a fence for my dog

This is one of those tools that's hard to find a use for, but then when an emergency comes up (some sort of flooding) you're insanely glad you have it. Value the batteries at $50 ea, so the tool is $100. Even back to BF, this is an excellent price for the pump

Yea not seeing it. Just get one of those drill versions. There are a bunch of them that work really well and pump faster.

I needed something like this when troubleshooting the sprinkler system. I turn the system on to locate the leak. The leak fills around the head. I empty the water with this and make the repair. I do this rarely, so I bought a cheap one, less than $20. If I ran an irrigation company, this Milwaukee is an excellent deal.

Must resist. Its a good deal on the batteries, but not much benefit over any old $20 120v pump.

I bought this kit last August for $189 at Home Depot and even though I bought it to only use it one day a year, I like it a lot.... Right before the freezes become a worry (usually in late September) I have to drain our outdoor fountains so they don't freeze/destroy the pumps. I'm already in the Milwaukee ecosystem and it's good to have in case of other water emergencies. For a few years, I hemmed and hawed at buying this for one specific use (while struggling through my previous solutions listed below), but the cheaper price sealed it for me - glad I did it.

Previously I used a cheap Harbor Freight drill-powered pump (you have to sit there and run the drill to keep the pump going - and you have to have one hand free to position the suction hose at the end to get everything), or I ran the hose like a siphon (if you like sucking on a hose for a while and then getting some nasty fountain water in your mouth, and this method never gets the last 1" or so of water and sediment unless you wait around to make sure the hose is positioned 'just so'), I used the five gallon buckets you scoop and carry (tedious, you get covered in 5 month old fountain water/algae as you scoop and carry bucket after bucket, then you have the remaining 1" of water to deal with, that the bucket just can't get), and then of course the shop vac (which works, but you have to roll it over to a place you can empty it several times and it's not completely tidy doing it this way), but this Milwaukee is much more convenient (you just hook up a hose and turn it on - it gets nearly all the water (maybe 1/10" left) and evaporation or my previously mentioned shop vac gets the rest if there's a lot of sediment).

Sorry for the long post on my use case.

I appreciate your post. I got a 50 gallon kiddle pool. I tried the cheap o battery transfer pump and its not enough. I got a 5 gallon shop vac and it sucks lugging those loads to the sidewalk. Im on the fence of getting 50ft garden hose and sip on. I dont think im ready to spend 200 on a pump.

Is this a brushed or brushless pump?
