Lawnmower/strimmer

Robomower. 100%. Haven't mown the lawn once in a year and it's perfect.

Lawnmower

Depends on how big your lawn is, really - AdvancedRotak 650 was the recommended mower for mine (~ 50ft garden, can be had for £200)

If you want to get more heavy duty sanding done, I’d get this:

Pressure Washer

Karcher. If you want something smaller the K2 is good. Once you get one, remember that you need to refer to it as a Karcher not a pressure washer so people know you have one.

N00b question

Not unless you are using it as a strimmer. It will cut down anything that stands in it's path. You will need a hose to feed into the pressure washer anyway.

Probably going against the grain and raison d'etre of the forum here, but your garden is under an acre right? Just get a 2nd hand Flymo and save the landfill. For a strimmer get the lightest thing you can. I picked up one for £8 from a boot sale and it’s brilliant. Light, takes up no space (32" tip to toe), and works. If you need a heavy duty one to clear stuff now rent a proper petrol one for the task.

I have the dewalt that soul linked which was an upgrade from a cheaper bosch green I had. I like it a lot. One thing to note is it has a stupid sized hose port so if you want to connect a dust extractor to it you need to get an adapter. Dust extraction is pretty good, (but it's no festool).

I'd sell mine and upgrade to a 6 inch festool if you want it.
