The total time for 13.7m2 (five panels x two sides) was about an hour. It cleans all bar a small part of the top and bottom corners. It is excellent at edge cleaning as the pads protrude slightly outside the body and get right to the edge. The pads rotate against each other – more efficient than a single direction wipe. Then it swings sideways to allow the bottom pad to clean the next few centimetres. The top pad acts more as an anchor point as it crabs sideways across the glass. You can choose either direction as well as a bottom to top crawl to start the cleaning. Later we found it more efficient to place it at the top of the glass and let it clean down because it leaves the top pad dry to polish the glass. That is almost the claimed speed of four minutes per 1m 2.Īt first, we placed the device upright at the bottom of the panel, and it started cleaning, side-to-side, crab-like up the glass. The 1.37m 2 glass panels took precisely six minutes to clean. In a millisecond, it vacuum sticks to the glass and starts its cleaning pattern. Hold the device on the window and flick the start switch. Place a clean pair of microfibre pads on ‘wheels’, take it to a Window, turn it on. Respect 240V power! Stage one – dry clean We strongly recommend using an AC powered device outside with an HPM Electresafe Power Centre – it has an RCBO (Residual Current Breaker with Overload) to stop anyone from getting electrocuted by detecting a ground leakage. If you clean windows further away, you can use an AC extension cord but be aware that no robot window cleaner can support a heavy power cable as well. Don’t forget that you need to allow for vertical height as well. It has a 4m DC extension cord to the power brick meaning maximum reach is about 5 metres from a power point. Hobot’s UPS (uninterruptable power supply) will hold suction for 20 minutes if it loses mains power. So, we charged the device (a few hours) with its 24V/3.75/90W charger. If you don’t do two passes, you risk getting a streaky result. The first ‘dry’ removes dirt and detritus, preparing the surface for a ‘wet’ nano-spray pass later. Robot My Life made it very clear that the best results were with two passes. We will let the image do the talking – two cleaning pads (microfibre), a 15um ultrasonic spray unit, DC power (we will explain why later), some smarts and an app (not necessary for use). It is smaller and lighter than I expected, and that is good – it has to ‘adhere’ gecko-like to glass, and I guess physics would preclude something much heavier. Let’s say that it is a great proving ground for the Hobot 388. Clean windows – ha! Clean them one minute, and very soon, that fine salt spray settles on them again. Those fantastic water views come with a never-ending fight against saltwater’s corrosive effects. And we learned what it meant to have a sea change. It is right on Brisbane Water, not far from the Hawkesbury River mouth and across the bay to the North Sydney beaches. It holds patents for the Hobot design and several innovations.Ī few years ago, we bought our forever home on the Central Coast of NSW. Hobot (Est 2010) is a Taiwanese company focused on home robot development.Price: RRP is $540, but there is a special price of $475 at the review time.From: Robot My Life is an Australian company based in Victoria.Well, it beat all expectations, and the result was sparkling clean windows with a minimum of human intervention. The manual is pretty simple – it has basic information but perhaps not enough to know what to expect. There was some trepidation as I opened the box and found a relatively small device 295×148×95 mm x 915g looking not unlike a dual disk electric car polisher.
