I just moved into a new place with a backyard at is 1/3 of an acre. It is a complex yard with a pond, large tress, fences, garden. It takes me about 2hrs to mow the lawn with a 21" deck. Being busy with work, inconvenient timing or other - I didn't get around to manual mowing as often as I would have liked - the yard looks so much better when mowed. And, I do have other yard work that could use some attention. So... A robotic mower was the solution. Like many, I did not want Wires and such - I wanted simple, WiFi connected and a great app for starting and monitoring. Although I have only has the A3 for 3 weeks - it has met my expectations! The neighbor looked over the fence yesterday and commented that the lawn had not looked that great in many years... Now, I run the A3 whenever I like... Fully unattended. Being able to alternate mowing angle is a nice add. The app is pretty easy to use but I am still working out some of the mapping and exclusion zones and setting a path to my garden shed where the base is. One thing I did not expect was the feeling of help it provides. I have a capable helper! Another potential benefit is that my realestate agent has mentioned that my property size would deter many buyers due to the upkeep. Well, the A3 will be sold with the property which may lift overall interest!

In addition to the A3, I have a Dreame L50 Ultra (Awesome), a robotic pool cleaner and I have started researching robotic pool skimmers. All of these devices have added value and removed me from mundane chores. Having a great looking yard, clean floors and a sparkling pool permit greater time to enjoy vs. maintain.

Have been using another make for 3 years. This unit ibetter built has a bigger battery and a much superior cut. We highly recommend this Dreame mower. Only small issue is that it drops down to its lowest cutting height went doing edge cutting on automatic. We’re now using manual.

Since I've set it up, it's been smooth sailing as far as doing the job unattended. The part that I find frustrating all have to do with the app:
- Human detection notification do not let me view a picture of what was detected.
- The camera (live view) icon in the app does nothing
- Quite often entering the app has multiple blue popup messages, the maps takes a long time to load, and it just doesn't feel smooth at all. It can take upward of 30 seconds for things to settle and be able to have a decent UI to use.

All things which could be fixed with eventual update. The robot itself seems solid, but I mapping was painful because the robot only has one speed when you're controlling it to setup the map: too slow. It took most of an afternoon to walk the robot around all my perimeter and obstacles.

All that being said, now it's done and it has been performing reliably. The only little negative I have noticed is that when the robot run out of battery in the middle of mowing stripes, it will simply turn around and go in a straight line to the base station, which mess up the stripes. I would appreciate if the robot could either finish the stripe or backtrack on the existing stripe and use the perimeter to go back to the station so it doesn't leave a trail of "going back to the station" across all the stripes it just did.

The quick-release blade system on the DREAME A3 Pro is honestly a poor design.

The small ball bearing in the locking mechanism can seize up with dust and debris, which means the blade will not release when it is time to replace it. Instead of being a simple maintenance task, you end up fighting with the locking block, trying to pull it off the shaft without breaking anything.

The problem is that the locking block will not slide out because the ball bearing does not retract properly. For a part that is exposed to grass, dirt, dust, and moisture, this mechanism really should have been designed to tolerate debris much better.

Blade replacement should be quick and simple. On this mower, the “quick release” system can become the exact opposite.
