What does a conversation handled by the AI look like?
Example conversation
Drain cleaning company AI agent
Customer: Are you available now? My sewage is overflowing
AI agent: Call logged. Send me the address, a landmark and what is overflowing: sink, toilet, floor drain or sewer?
AI agent: This reaches the on-call person in writing.
Is an AI agent or manual customer service better for drain cleaning companies?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service, someone at the drain cleaning company has to stop what they are doing; with the CertuAI agent the answer goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Call at three in the morning | Only seen in the morning, when the customer has already called another company | Answered right away, with address and problem logged, and the crew called |
| Confirming whether you serve the area | Found out after half an hour of conversation | The first thing the agent confirms, using the neighborhoods you registered |
| Price range | The customer insists on the price and the conversation stalls | The range you set, given right away, with the visit to close the deal |
| Arrival time | Promised off the cuff, and the customer holds you to it later | The estimate you set per area, always the same |
| Volume of calls when it rains | Phone busy and messages piling up | Everyone answered at the same time, in the order you prioritize |

It does the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers clients your way, with your rules.
Service at any hour
Middle of the night, Sunday and holidays: the call is answered and logged right away.
Area confirmation right at the start
The neighborhoods and cities you serve, checked before any talk about price.
Price range and arrival time
By type of service and by area, with the estimate you set, always the same.
Triage of what is clogged
Sink, toilet, floor drain, grease trap or street sewer, and whether it is overflowing right now, because that changes the equipment.
Calling the crew
Address, landmark and situation reach the on-call person in writing.
What questions do clients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at a drain cleaning company no longer depend on you having your phone in hand.
How does the agent start answering customers at the drain cleaning company?
In three steps, on the same day. No installation, no code and no changing the number clients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.

The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan.

Create my agentWhat needs to be ready before turning the agent on at the drain cleaning company?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The neighborhoods and cities served, with the estimated arrival time for each area
- The price range by type of service: sink, toilet, floor drain, grease trap, sewer and hydro-jetting
- The questions that define urgency: what is clogged, whether it is overflowing and whether it is a house, a business or a building
- Who is on call in each time slot, including the middle of the night, Sunday and holidays
- What the company does and doesn't do: breaking floors, replacing piping, septic tank cleaning, video inspection
Whether the agent calls the on-call crew directly in the middle of the night, or every overnight call waits for you to confirm before the crew leaves.
The most common mistake: Not registering the limit of the area served. Twenty minutes of conversation to find out the address is outside the area is time that someone with overflowing sewage doesn't have, and they will go with whoever answers that first. Read how to fix this.
Frequently asked questions from drain cleaning companies
Does the agent really answer in the middle of the night?
Yes, and that is the main reason to use it. Someone with sewage overflowing at three in the morning goes with whoever answers, and the agent answers.
Does it give a fixed price?
It gives the range you set by type of service and explains that the final price comes once the crew sees the site.
How does it know whether I serve that address?
You register the neighborhoods and cities you serve. When the address is outside the area, it politely says so right at the start, without making the customer wait.
Does it tell a clogged sink from street sewage overflowing?
It tells them apart through the questions you define. What is clogged, whether it is overflowing right now and whether it is a house, a business or a building change the urgency and the equipment the crew brings.
Does the agent call the on-call crew in the middle of the night?
It does if you set it up that way. There are two paths: the agent calls the on-call crew directly, or it logs the call and waits for you to confirm before the crew leaves. The first wins the customer at three in the morning. The second protects your crew from going out on a call that doesn't hold up.
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?
These pages explain the same agent from another angle: how it works, price, common questions and comparisons between platforms.
In short
A clogged pipe goes to whoever answers first. The agent answers in the middle of the night, confirms the neighborhood, gives the price range and calls the crew with the job logged in the CRM.
