The Hom-Bot Square is easily the most distinctive robotic vacuum cleaner in this shootout thanks to its glossy candy red chassis and its square design. According to LG, the Hom-Bot Square features a square design so that it can better clean hard to reach corners with its long sweeping brushes.The Hom-Bot Square also has a highly advanced system of sensors that includes three front-facing ultrasonic sensors, cliff detectors near its sweeping brushes, and a top-mounted camera and bottom-mounted optical sensor that is together known as Dual Eye 2.0. This array helps the device to create an accurate map of its surroundings and pinpoint its position in a room. The top camera takes as many as 30 photos a second, whereas the optical sensor can scan the surface up to 2,000 times a second. The device offers four different cleaning modes: "Cell by Cell", "My Space", "Spiral" and "Zig-Zag". The first two are arguably the most useful. In "Cell by Cell" mode, the Hom- Bot Square divides the house into smaller blocks and then proceeds to clean each block before moving on to the next.

There is also an additional "Turbo" mode that is automatically activated when the Hom-Bot Square senses that it is vacuuming carpets.In "My Space" mode, users can specify the area to clean by first directing the Hom-Bot Square to draw its boundaries. It will then proceed to only clean the area within these drawn boundaries.This is useful because users can direct the Hom-Bot Square to areas that require more attention and also keep it away from areas that it might get stuck in.shark upright vacuum cleaner reviewsOn the whole, we were pleased with the Hom-Bot Square's cleaning abilities. vacuum cleaner perth storeWhile it was amongst the quietest, that does not mean that it has sacrifice on suction power and we found that it was able to clean thoroughly.vacum cleaner kecil untuk mobil

Maintenance is also very easy, simply open the top lid to remove its dirt bin. However, since its uses a brush roller at the bottom, users would need to clean it regularly to prevent dirt from accumulating and restricting its vacuuming performance.On the navigation front, we were pleased to find that unlike other robotic vacuum cleaners, the Hom-Bot Square does not gently bump into object to see if it could actually go through them. It dutifully avoids any obstructions that its front-facing sensors pick up and only attempts to get as close as possible to clean around the obstruction.Sadly, despite its advanced sensors, we found that the Hom-Bot Square would sometimes miss low-lying objects and was prone to get stuck in certain situations.For example, since it was programmed to go as close as possible to obstructions, we found that cleaning the sides of walls, its sweeping brushes often got tangled with wires. The sweeping brushes would also get tangled up in other objects such as light rugs and even loose fibers from carpets.

VR5902LVM attached to the charging station Roboking (Also known as Hom-Bot) is an automated robotic vacuum cleaner produced by LG. The first version of the Roboking was launched during 2001. It is also sold as Hom-Bot. As of 2011, it is the quietest vacuum cleaner robot on the market, producing 48 decibels (dB). The Roboking navigates by performing SLAM (simultaneous localization and mapping) to build a map of its environment using ceiling images, while tracking its incremental movement with a downward-facing camera (like an optical mouse). A combination of ultrasound and infrared helps minimize collisions in dynamic environments and optimizes performance by planning the most efficient route.

LG claims that these sensors are more effective than the more conventional options of bumpers or light sensors. During homing, the robot goes directly to the remembered location of the charging station rather than looking for it with the help of sensors. Remembered path also helps it to clean multiple rooms. Like most of other cleaning robots, Roboking is capable of independent docking with its charging station and of scheduled cleaning that starts after the specified number of hours. It cannot be programmed to clean periodically without user interaction and must be serviced after cleanup to empty the dust bin. Remote control provides commands for cleanup, homing, steering and timer setup. It is reported that the lack of bumper sensors causes the Roboking to push up against obstacles without realizing it, possibly moving them. "This pushing against objects is the single biggest issue with this product.However 2011 year model has ultrasonic sensors to slow down and turns back if it cannot pass the obstacle.

[2] The device is also both advertised and described in reviews[3] as comparatively silent. The 2011 year model contains 22 sensors attached on 32 bit microprocessor.[3] The device runs Linux kernel 2.6 and internally uses Bash, BusyBox, U-boot, glibc and OpenSSL.[2] Source code, where required by the licenses, is available from the address, included in the manual. 1900 mAh Lithium-ion polymer battery is sufficient for 75 minutes of cleaning. The cleaning mechanism is relatively well enclosed and the dust bin is fully closed when removed, resulting cleaner and less maintenance. The device offers several cleaning modes. During the spot cleaning the robot circles around small, highly contaminated area. During Zig Zag cleaning, it attempts to cover all space in long "wall to wall" sections, resulting in faster but possibly less accurate cleaning. During Cell by Cell (or spatial extension) cleaning it divides the bigger area into cells and cleans each cell separately, only moving to the next cell after the current one is complete.
