Karcher RC 3000 RoboCleaner

RC 3000 RoboCleaner, the fully automatic floor cleaning robot. The autonomous floor cleaning system that sweeps and vacuums even when you're not at home. For carpets and hard surfaces.

The Karcher RC3000 is a robotic vacuum cleaner that will clean your floors even while you're not home. It can even clean multiple rooms in your home without any help from you.

The Karcher RC3000 is equipped with a flexible sweeping mechanism. This allows it to adjust to different floor surfaces as it moves to different rooms in your home. The Karcher RC3000 can be used with carpet, linoleum, and tile surfaces. However, it's best not to use this robotic cleaner with carpets that have a long pile.

When the Karcher RC3000 is running low on power, it will automatically return to the base station to recharge. The unit can run up to an hour before it needs to be recharged. It only takes the Karcher RC3000 20 minutes to charge up enough to get back to work.

You will also like the lack of maintenance required by the Karcher RC3000 robotic vacuum cleaner. While at its base station recharging, the cleaner will automatically empty debris into a full-size filter bag. This means that you won't have to empty a message dust cup like other designs. The filter bag will last for weeks before you need to empty it. The unit will alert you whenever you need to change the filter bag.

The Karcher RC3000 also has a low profile. This allows it to travel under furniture such as beds, sofas, and tables. It also has low impact bumpers so that it won't cause any damage whenever it runs into walls and furniture. The Karcher RC3000 also has a stair detection feature. Therefore, it's safe to use on upper floors without worrying about it rolling down stairs and getting damaged

REVIEW ENDO SPRING BALANCER

What is Spring balancers?

The tension is kept stable on even if the cable is pulled out or retrieved because of the tapered drum.

So Spring balancers can hold the tools suspended in hollow and work for flexible positioning of the tools. Workers can enjoy comfortable operation with less fatigue.

ENDO Spring balancers can play their active parts in;
■Suspending a tool for product assembly line.
■Frequent fastening screws, bolts and nuts.
■Suspending a jig, tool, welding gun etc.

Advantage
■The balancers improve working efficiency and diminish worker fatigue.
■The balancers make the position of a tool stable and contribute to accurate work.
■The balancers are available for keeping a tool clean.
■Any electric or pneumatic power is not required and safe working is achieved.

Selection of suitable model
Always use a suitable model meeting the total weight of suspended tool or instrument.
The balancer should be selected considering the weight of the tool and accessories.
(Example)
1. The weight of a tool (assuming that it is 14kg) ＋ the weight of accessories (3kg) is equal to 17kg (Total weight). EWF-22 or ELB-22 (15 to 22kg) is suitable for the application.
2. If the total weight is on the border of models, please select larger model. It will provide longer spring life.
The tool weight (19kg）＋ the accessories weight (3kg) ＝ 22kg. EWF-30 (22kg to 30kg)
should be selected. If the fall arrest system works at the situation, please add an additional
weight to recover the system.

Installation
■Install Spring balancers uneven not to hit each other when the balancers are installed in a line.
■Always employ a secondary support chain and leave the slack for smooth swivel.
■Always adjust the spring tension to meet the total weight of tool and the application.

Spring tension adjustment
Worm gear system, Ratchet system or Handle system are available and dependent on the models.
Clockwise adjustment increases the spring tension and Counter clockwise adjustment decreases
the spring tension. (The spring tension has been set at the middle of capacity in advance prior to
shipment)
