Predictika · Professional high-pressure cleaner orders

An AI sales agent's professional pressure washer order, checked before it goes out

An AI sales agent prepares an order for a professional high-pressure cleaner with its nozzles, foam system, surface cleaner, hose and other accessories. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the machine and accessory data sheets and returns a verdict, every reason and the figures it computed.

Scope: Five Kärcher professional HD and HDS high-pressure cleaners and their data sheet accessory lists, site power, water and operator rules. See everything this validator covers

This validator models orders for five Kärcher professional high-pressure cleaners, not just the scenarios shown below: HD 6/15 M, HD 8/18-4 M, HD 8/18-4 M Plus, HDS 8/18-4 C and HDS 7/16-4 C Basic.

  • Accessory compatibility — for each machine, the nozzle or rotary jet, foam lance or foam set, foam nozzle kit, surface cleaner and its nozzle kit, spray lance or servo control, high-pressure hose, water connection part, generator and hose reel kit must be on that machine's accessory list in its Kärcher data sheet.
  • Parts that need a companion — the Inno and Easy foam sets and the FR 30, FRV 30 and FRV 50 Me surface cleaners need a machine-specific nozzle kit ordered separately, and FR and FRV cleaners take different kits.
  • Site, water and operator — the HD 6/15 M runs on single-phase 230 V and the other four machines on three-phase 400 V; the three unheated HD machines allow an inlet water temperature of 60 degrees C at most; the data sheet states that the hot-water HDS machines require instruction.
  • Stated figures — the maximum working pressure and flow rate stated on the order are compared with the data sheet figures for the machine.

Any order for these five machines that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the data sheets carry none, so this validator produces no price build-up or line-item quote), the other Kärcher machine families, other accessories and wet-blasting attachments, spare parts, and regional variants of the data sheets.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Accessories that exist for only some machinesOnly with care
Each machine has its own accessory list, so every part needs a rule per machine. It works, but five machines and over 40 parts mean hundreds of rule entries to keep in step with the data sheets.		Each choice is checked against the machine's data sheet list, in one request, whatever order the choices arrive in.
A part that needs a separately ordered companionOnly with workarounds
The foam set and surface cleaner depend on a kit that sits on a different line; a rule has to look across lines, and the kit type must also match the cleaner type.		The companion kit and its type are checked together with everything else.
Site power, inlet water and operator instructionOnly with care
These are order-level facts that depend on the machine chosen; a rule can compare them, but someone has to write and maintain each one.		They travel with the order and are compared on every call.
Stated pressure and flow that must match the data sheetOnly with care
A stated figure is a free-entry field; a rule can compare it with a looked-up value, but someone has to write and maintain that comparison for each machine.		The stated figures travel with the order and are compared with the data sheet figures on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a professional high-pressure cleaner with its nozzles, foam system, surface cleaner, hose and other accessories. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the machine and accessory data sheets and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an order for Northgate Food Works: one HDS 8/18-4 C with large dirt blaster, size 045, Easy foam set. The order states a maximum working pressure of 200 bar and a maximum flow rate of 800 l/h. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings, all in one answer. The machine needs a different electrical supply than the site provides; the HD 6/15 M runs on single-phase 230 V and the other machines on three-phase 400 V. The data sheet states that this hot-water machine requires instruction, and the order records no instructed operator. The Inno and easy foam sets need a machine-specific nozzle kit, which the data sheet says must be ordered separately; the order has none. The other one is on screen.
    6. 
      
  6. The validator returned four blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for site power, inlet water and operator instruction, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the site power to three-phase 400 V, the operator instruction to instructed, the foam nozzle kit to nozzle kit 055 for Inno/Easy foam sets (500-600 l/h) and the stated max working pressure to 180 bar.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The foam nozzle kit on the order is not in the data sheet accessory list of the selected machine.
    12. 
      
  12. Four findings cleared, but the change brings a different blocking finding: foam nozzle kit is not listed for this machine.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the foam nozzle kit to nozzle kit 090 for Inno/Easy foam sets (700-1,000 l/h).
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Four problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    19.
