I have decided to grab one of these to try and keep our Labrador's shedded fur from drifting around the house in between 'proper' vacuums. Could just be a gimmick, but they look cool so I'm keen to give it a go. ;) The online reviews seem positive too.
Seems like a decent price, requires no haggling and includes free shipping to your door. Not sure how long the sale is on for.
Ps. Kambos is WA only as far as I'm aware.
The Roomba 600 series is amazing.
I grabbed the Roomba 650 from this deal for $327 delivered. https://www.ozbargain.com.au/node/96148
Considering the price $509, it isn't really a good deal.
