OK but don't expect it to do the whole job.  You will have to guide it and pick up the smaller trash.

Its ok for the money.  But if you make the purchase, be prepared to swim with it.  It vacs like it should and picks most things up (although I watched it roll over some sand and it didn't pick any of it up).  Picks up most bigger trash but small particles such as sand, it will not pick up.  But the biggest complaint I have is that you have to guide the thing.  So you will have to get into the pool and swim with it.  I have ran it 3 times and made the proper adjustments (there are only 3 setting adjustments that you can make).  Every time it wants to move down to the deep end and stay there.  The shallow end stays dirty.  Unless I stay with it and make it stay in the shallow end.  But that takes away the purpose of having one.  One other thing I need to mention.  When it arrived, the top unit was internally broken.  The shipping box had no damage so it was shipped from the manufacture broken, that's the only conclusion.  What happened to quality control in this manner?  I had to wait an additional 2 weeks to get a replacement.  And only then did they just ship the top unit.  I was concerned that if the top unit was broken, the bottom would have some problems as well.  And maybe that's why it will not vac the way its suppose to.  Who knows.  I am sure it will not last more than a season.  And its not doing the job anyways.  So may be looking to replace it soon.  I love the idea of a robotic vac but no of them seem to last very long.  But this one was shipped damaged.  So not looking for any miracles here.

If you are looking for a product to turn your shop dust collector system into a 2 stage "cyclone" type system. THIS IS NOT IT!  This design does not collect all that much of the incoming dust. Yes, some of the bigger pieces will go into the trash can, however the finer dust still gets sucked up and sent to the the dust collector system. When the majority of the dust is just be sent to the dust collector, it defeats the purpose of a 2 stage system. Recommend that you buy a "real" cyclone type unit if you want an effective 2 stage system. I know I will be doing that.

This doesn't pick up much - just doesn't seem to have the strength.  After a few uses it was regulated to the back of the closet to be forgotten.  Found it again while moving and it now resides in a landfill.

We have a very muddy back yard so we bought this hoping it would catch some of the dirt our dog was constantly tracking it. It does an OK job, definitely grabs some of the dirt but not as much as I hoped.

It will do the job. It's just once you get the tree in it, it's hard to control to move from place to place.

Good design, however it is a bit on the light-duty side. I did not expect too much as it was an inexpensive unit. If you are going to set up outdoors as I do sometimes, I would suggest a heavier-stronger unit. Like that it came with a small carry bag.

Did not purchase this from Amazon, but received it in the mail the other day.  The product is decent, however, I can not say that it is all that much easier than a quick manual vacuum.  It can get stuck on cords and turn off on top of ledges.  Maybe because it is new I tend to spend more time watching it and babysitting it then feeling it has lightened my efforts.  Also if you want to have it work on an area, you have to pretty much block it into that area.  The waste tray is small and should be emptied every use.  It is random in its movements to some degree in that it may fail to go into a particular room or area because it just does not bump and rotate that way.  At first I could not get it to effectively operate on carpet until I figured out that it works if I take off the mop cloth.  Upon doing so it no longer fails on carpet.  The device would work much better if you have an unconfused environment as it can not go behind things or move things or can knock over things or get caught on things.

In the end I have decided to keep this as it is "okay enough" and vaguely interesting.

Bin is not large enough, have to empty it a little more often than I would like. Dusting brush at the end is virtually useless. Otherwise, works well.

Does the job but you have to pick up the bag slowly. If you pick it up too quick, the scale cuts off.

I had high hopes for this sweeper but felt it was actually more work than the cheapest sweeper out there. Pro: Great if you can't handle pushing much weight. Just don't expect it to pick up much debris unless you put a lot of your own weight into it. Bottom line, there are better, more affordable sweepers out there.

the pieces  are not as small as I had hoped after shredding, but ok.  it does seem to pull paper in at an angle sometimes and it jams causing me to reverse the motor.  wish it had a larger basket or that you could put this shredder over a larger basket. BUT  with the safety switch that keeps it from not working until bin is securely in place this is not an option.

Magnetic Separator Pick up appears well built although I doubt it would pick up a 16# item however, it will do what I need it to and that's all that counts.

It works good, but if I were to buy it again getting one a little more narrow might have been good.  If the ground is anything but flat it can get hung up and just drop all the metal it just picked up because the bottom scrapped.

It works pretty well. I still have to go in and scoop some "hard to get" areas. It's much better than scooping all of it, though.

This works just find if your expectations aren't to high for it. Fan's a little slow. 8 double A batteries. I will probably get  rechargeable unit from the Shack. When the bag gets about 1/4 full. The unit is going to want to float. Nice not having to deal with the garden hose like you would have to on the non battery operated one. But I'm thinking I might just go back to the hassle of doing that.

This Perfect Sweep is ok, but it really doesn't have very much suction power for picking up sand or cat litter.  It does pick up dust and hair.

It works but not as well as I had hoped. The suction is not as good as plugging the hose in directly, but it is nice to catch the debris in the basket.
