Easy To Use, Light Weight, Fits Tight Spots
This is an excellent cordless mower for small yards or for cutting in tight spaces around flower beds, decks, porches, fence lines, etc.

Assembly out of the box takes 10 minutes. You'll only need a phillips screwdriver to attach the handle.
For safety, it even comes with a key that you can keep secure, the mower will not operate without the key. Keeps curious kids from starting the mower.

Once assembled, charge the battery using the wall charger. When the light is green you are set. Max charge time will take 4 hours, usually less.

Fully charged this will run for about 30 minutes cutting normal lawn grass.

The collection bag fits securely on the back and will hold ten gallons of clippings/leaves before it needs to be dumped. It removes easily for fast bag emptying.

Deck height has three adjustments and can be done tool free. Love that!

This cuts easily, pushed like a dream because it barely weighs 23 pounds total. On regular grass we cut 30 minutes of cut time, on very thick or damp grass cutting time will be reduced.

This is an excellent mower for those that have small yards, condos, or like me, someone that wants to trim close to garden features, lawn ornaments, against fence lines and garden beds where the big riding mower won't fit.

I highly recommend it.

Great little mower
My first electric mower. The battery does the job as long as you don't mow in one of the two higher speeds. I have an average yard and it does the job. Quiet & lightweight. No gas, no oil. Wonderful.

Worked great right out of the box.
Delivered from Amazon in 2 days. Worked immediately right out of box. No problems. I have only 900 sq ft of grass. Did the initial battery charge, mowed twice, battery is still in green zone.

I haven't owned my mower very long, but love the convenience of using it! Since I enjoy mowing, it doesn't matter that it's a 'mini', and takes a little more time, I can still mow. I'm so happy a friend suggested the battery-powered option.

Excellent choice
Got this for our daughter, the perfect answer for front and back lawn. Get both done , about 1/4 acre total back in garage for recharge. No gas, no noise , no fumes, no oil changes. Does a remarkable job.

Not for people with disabilities
Was difficult for me to push and turn. For healthier people it would be ok. However, the battery died before I could get back from doing just one row. Due to my not being able to move fast.

Our little Sun Joe cordless is our second purchase-- We bought a corded at the start of the season--love it---but it's tough to get enough cord to the sides and top corners of the yard.
So we bought the Sun Joe cordless--and it is just as capable as the corded version--but we're keeping both- because we use them for different situations.
I will say too that we bought the optional side discharge assembly-- and exceptionally good investment since the Sun Joe Grass Basket is so small as to be of little practical use.
Overall-- both the corded and the cordless are amazing little machines that cut our yard extremely well--and are virtually maintenance free--and non polluting.

I LOVE my Sun Joe lawn mower. I was so fed up with my temperamental gas mower. It often didn't start and I wanted a change. I decided to look at electric, and realized I didn't want to mess with a cord. I found Sun Joe online and figured it was worth a try given the reasonable price. It had me at hello! I did have to re-charge to get through my lawn the first time since things were quite overgrown, but it was up to the task! It charged through everything with the sharp blade. Since the first go round I'm able to mow my entire lawn on one charge with "juice" to spare. I don't think I'll ever go back to a gas mower after this experience. And now I'm eyeing the snowblower...
