My portable ultrasonic turbine mini washer

Other than my CCKO CK9919 stainless steel smart garbage bin, I have also purchased a portable ultrasonic turbine mini washer at the price of slightly above RM40, during the recent 11.11 big sale promotion festival. It is mainly used to wash the mopping cloth of my Roborock S7 robot cleaner.

Inside the packaging box, there are:

• The round washer unit with 9cm diameter, which can be put inside water.
• USB cable with a controller unit in the middle. The controller unit cannot be put inside water.
• USB traveler wall charger, also cannot be put inside water.

Some similar products come with a water bucket. The water bucket can even be foldable to save storage space and to make it easier for carrying along. However, those units with attached water bucket can easily cost double the price than this one.

As you can buy a bucket at the price of a few ringgit only, I think this unit without bucket is good enough, and it has a much better cost-performance ratio.

There are 3 suction cups under the unit. You can stick it at the bottom of a water bucket, or at the inner wall of the water bucket, or inside a basin, or inside any suitable water container.

This mini washer is designed to wash up to 1kg load of clothes, which is more than enough to wash my robot's mopping cloth.

It has 4 modes of operation, controlled by its controller:

• Mode A: cycles of 2 minutes forward and reverse spinning + 1.5 minutes of ultrasonic cleaning + 5 minutes of bubble cleaning
• Mode B: forward and reverse spinning
• Mode C: ultrasonic cleaning
• Mode D: bubble cleaning

Its forward and reverse spinning action will produce a swirl in the water, to clean up the clothes inside, similar to the way of how ordinary washing machine functions.

When the washing is finished, you can switch off its electricity power at the wall socket to turn it off. Otherwise, it will automatically turn off itself after 30 minutes of operation.

See it in action in the video below:

I find it to be a very good companion for any robot cleaners with mopping function. You can wash several mopping clothes together at one go with it.

My CCKO CK9919 20 litres stainless steel smart rechargeable sensor garbage bin

During the recent 11.11 big sale promotion festival, I have purchased a CCKO brand (model CK9919) 20 litres stainless steel smart rechargeable sensor garbage bin to be used in my kitchen. Its price was around RM170 after discount.

It is "smart" in the sense that it can automatically open its lid whenever its infra-red sensor detects an object near its top, then start a 5 seconds countdown after the object is cleared, and then automatically close back its lid.

You can see it in action in the video below:

Besides infra-red object detection, its lid can also be automatically opened by slight vibration to the bin (such as gently kicking its body) or by pressing a button on its top panel.

In this way, you can throw your rubbish into it without touching any part of the garbage bin. Convenient and hygienic.

There are other even smarter models of garbage bin available in the market. Some can even automatically wrap up the garbage bag inside when it is full, and automatically reload a new garbage bag after the existing used one is taken away. However, those types of smarter garbage bin require the use of their own special garbage bag (which is not cheap), and their price is higher too. Therefore, I did not choose those smarter type.

There are quite a number of different sizes available for CCKO elegant stainless steel garbage bin. In terms of shape, there are also 3 choices: round cylinder, rectangular and square.

For kitchen use, I found the rectangular type is more space-saving, and the size of either 15 litres or 20 litres is more suitable. Both the 15 litres and 20 litres have the same base size of 30cm x 22cm. Their difference is on the height: 20L one has a height of 50.5cm whereas 15L one is 39.5cm.

You can use smaller size one for living room, bedroom, writing desk, toilet, etc. accordingly.

The CCKO smart garbage bin consists of 3 parts: the stainless steel outer bin, black colour plastic inner bin, and its cover. Just like normal garbage bin, you can put garbage bag inside the inner bin to collect your rubbish.

This CCKO garbage bin comes with a user manual, a QC certificate, a USB charging cable, and 3 sample garbage bags. The user manual is written in Chinese.

Its actual opening available for you to throw rubbish is approximately 25cm x 13.5cm only.

The magic is played by its cover, with sensors and electronic motor to open and close its lid. It is powered by a 1,500 mAh rechargeable 18650 lithium-ion battery. The size of this 18650 battery is larger than AA size battery.

Charging can be done by connecting the round connector of its charging cable to its charging port, and the USB end to either a wall charger or a power bank. It is said that a single charge can last for more than a month operation.

When you take out the cover and turn it over, you can find 2 compartments. One is the battery compartment, and the other compartment is used to place a bag of activated carbon to remove bad odour.

I like this garbage bin very much. It is smart. Its stainless steel body looks solid, classy and elegant. It is easy to use.

More importantly, this CCKO CK9919 garbage bin is water-resistant, protecting its electronic parts from damage being splashed by liquid. I did read some online reviews to some of its cheaper counterparts without water-resistant feature that those garbage bin will stop working after some time, probably due to electronic parts damaged by liquid.

My B03 home-use upper-arm digital blood pressure measuring and monitoring machine with colour background and voice function

After I have purchased and used the Jumper JPD-500E fingertip pulse oximeter, I have recently added a B03 home-use upper-arm digital blood pressure measuring and monitoring machine for my family use.

There are several types of home-use blood pressure monitor available in the market, including the traditional bisep (upper-arm) type, wrist type, finger type, etc. The American Heart Association (AHA) recommends the upper-arm culf type for more reliable measurements.

This B03 upper-arm digital blood pressure monitor can operate with 4 AAA-size alkaline batteries, or powered with 6V USB power source. It has English speaking voice function, providing instruction for blood pressure measuring, and reading out the result after the measurement is completed. It cost slightly more than RM50.

This machine provides 3 measurement values, namely Systolic (upper) value in mmHg, Diastolic (lower) value in mmHg, and pulse rate in bpm. It has memory to store up to 99 times of readings each for up to 2 different persons. It will auto power-off itself 1 minute after measurement is completed and there is no further operation by the user.

Before its first usage, we need to set its date and time by long pressing the S button and then using the M button to do the value setting, so that the date and time for its stored readings are correct.

Blood pressure readings below 120/80 mmHg are considered in the normal range. High blood pressure a.k.a. hypertension is categorized base on severity into Elevated, Stage 1 Hypertension and Stage 2 Hypertension.

Hypertension is also called "the silent killer" as many patients do not have obvious symptom for years. They might not be aware of having hypertension, unless periodically doing medical check-up with doctor, or using this type of home-use digital blood pressure monitor to frequently self check-up.

Hypertension after the Elevated level will need to seek for medical consultation from doctor, and medication might be needed to lower down the blood pressure. Prolonged hypertension can cause damage to body organ.

On the other hand, low blood pressure a.k.a. hypotension refers to blood pressure readings below 90/60 mmHg. Hypotension generally has less impact to our health than hypertension, and usually does not need any special medical treatment, unless there is symptom occurred.

The B03 digital blood pressure monitor uses the standard from World Health Organization (WHO) to determine the category level of its measured blood pressure. Its backlight will turn green for normal blood pressure, orange for mild hypertension, and red for severe hypertension. This visual effect is very handy, especially for the elderly to know the category of their blood pressure level, without the need to interpret the Systolic and Diastolic readings themselves.

The more recent International Society of Hypertension (ISH) 2020 classification of hypertension is as below:

As mentioned in the User Manual of the B03 digital blood pressure monitor, our blood pressure constantly changes throughout the day. It tends to be higher in the early morning and also in the afternoon, and lower at night during our sleep.

There are many mobile apps available to help us record down and monitor our blood pressure readings. Unfortunately, the B03 digital blood pressure monitor is unable to send its readings to our handphone, and we have to manually key-in the readings in the app by ourselves.

One of the recommended mobile app to use is BP Journal developed by a Malaysian called Jason Ong (owner of PortalGroove Solutions). It supports a multitude of global and regional blood pressure classification guidelines (ISH, ACC/AHA, ESH/ESC, NICE, etc.). It supports multi-profiles and able to generate report so that you can share with your doctor or family members.

As prevention is always better than cure, it is highly recommended for every family to be equipped with an upper-arm digital blood pressure monitor, to be used by the whole family, especially the elderly. With the handy blood pressure monitoring machine, you no longer need to check your blood pressure at clinic, as you can self-service at home, and you can have as frequent measurements as you like.
