Is solely investing with Roboadvisers sufficient if one does not have the time to read up about or perform transactions in the markets?

You can also consider FSMOne RSP. Roboadvisors generally invest in ETFs and are largely exposed to US equities. I think it is also viable to do DCA into Vanguard S&P 500 using FSMOne RSP. It really saves you on the fees in the long run!

If you really don't have to the time or interest to monitor the markets, then yes Roboadvisors are a decent place to start.

However, I do feel you should at least know what you are getting into if you want to invest in a robo. It's not a good idea to just blindly put in money into any kind of investment.

Imma beginner — little knowledge on investment & low commitment !!! So, Robo-Advisors are really great for me

Hey Dylan!

What does sufficient mean to you? Are you saving towards a goal that requires you to drawdown the money in 3-5 years? (eg. to buy a house or car) Or are you saving up for retirement? If yes, then a robo advisor is probably sufficient. However, if you want to outperform market returns, you would be better off picking indivdual stocks and calculating your entry and exit points. Even then, the returns will differ to a great extent still and a lot more effort would be needed on your part to understand how the market works. Hope this helps!
