The best value leaf blower for lots 2000sft or less is 

This Ryobi P2109 18-Volt ONE+ Cordless Blower is perfect for blasting away leaves and debris up to 200 CFM and 90 MPH 

I have a 1,800 sqft house and this is a great blower for my yard, it's not too powerful so if you're space is bigger you are gonna wanna spring for the next size up, now back to the blower it's and easy put together tool it comes with the handle which the battery attaches to and two tubes, when I first put it together I had problems with the bottom tube falling off, I wouldnt recommend the way I fixed that problem which was holding the blower body and striking the tube against the ground to keep it from falling off, a better way would probably be to lubricate it with some soap and put the blower and hand on a hard surface and push down on the tube till it seats probably then let the soap dry before use, kind of like when you put a new grip on a bikes handle bar, with the old soap method, and you're good to go, running on a 1.5ah battery will most likely be all you need for a normal sized yard.

This pressure washer is on the smaller side of the spectrum of PSI and gallons per minute, it's perfect for the medium home owner, it's perfect for washing the siding of your house or car but if you are gonna wash your car I'd strongly recommend buying the other nozzles that come in different degrees of spraying, they recommend 40° nozzles for car washing to be the easiest on the paint (usually white) and 25° (Green)for power wash wheels tires and the undercarriage, and 65° (black) when using soaping tool, this model is perfect for those applications, anything more like cleaning a drive way or patio I'd suggest a higher PSI, while this machine will clean those surfaces, it won't clean as well as a higher pressured machine would so if you have oil and grease stained concrete, it would be a better outcome with a stronger machine, the one I'm reviewing here goes for $99.99 which is a great price for this machine, and just one more word of caution, some pressure washer brands have proprietary connections and not all fittings and hoses will work on some machines, so make sure you buy the right product with the connection that fits your machine..

This is a great budget friendly option for home use, it's not quite as robust as others and it takes a little more effort to start but for the price it is worth it for the average homeowner, string replacement is easy and it does feel nicely weighted in hand, so for someone looking for a cheap but good quality this is the one for you, I replaced my echo with this when the ECHO was stolen and couldn't afford to replace it, and that's been about 3 years now and this one is still going strong
