SEBO Automatic X4 Boost Upright Vacuum Cleaner (Arctic White) | #90506AM

The SEBO Automatic X4 Boost Vacuum Cleaner | #90506AM is the “no-guesswork” upright for carpet-heavy and mixed-floor homes. It uses electronic automatic height adjustment to keep the brush and airflow in the sweet spot as your flooring changes. And when carpet needs a deeper grooming pass, the Boost button lets you switch into a more aggressive brush action option—without turning your cleaning session into a settings-and-dials project.

Quick Highlights 

• Automatic height adjustment keeps performance consistent as flooring changes.
• Boost function gives you an extra “dig-in” option for carpets that need more agitation.
• One-sided edge cleaning helps clean tight along baseboards and edges.
• Large, sealed bagged system = cleaner disposal and steady airflow.
• 40-foot cord + large bag = fewer interruptions in bigger homes.

Recommended Floor Types

• Wall-to-wall carpet: low, medium, plush (Automatic + Boost is built for carpet performance).
• Area rugs: standard rugs and runners (use Boost when you want extra grooming).
• Hard floors: hardwood, engineered wood, LVP/LVT, tile, stone (the X platform is designed to clean bare floors).
• Pet homes: strong brush performance + large bag capacity helps manage hair load.

Product Description

The X4 Boost is designed for people who want consistent deep cleaning without constant adjustments. The vacuum senses brush resistance and automatically moves the power head to maintain strong pickup on both carpet and hard floors. When you hit a carpeted zone that needs extra grooming—high traffic lanes, pet hair build-up, or seasonal shedding—the Boost feature is there for a more “carpet-focused” pass.

Key Features

• Electronic automatic height adjustment: the machine adapts while you clean—no manual height dials.
• Boost button (X4 Boost): activate Boost when you want deeper carpet cleaning; it illuminates when enabled.
• Full bag / clog indicator with shutoff timing: helps protect airflow and motor cooling.
• Brush obstruction protection: stops the brush and shuts down if something jams, helping prevent damage.
• Tool-free brush roller removal + clog door: faster hair removal and simpler maintenance.
• Sealing strip for bare floors: helps reduce debris kickback on hard surfaces.
• Three on-board, full-size tools: crevice tool, dusting brush, and upholstery nozzle.

What Makes the X4 Boost Stand Out

• “Automatic” that you actually feel: the head height changes for you, so performance stays consistent across surfaces.
• Boost = carpet-first pass on demand: switch into Boost when you want stronger carpet grooming without changing machines.
• Big-home efficiency: 40 ft cord + large bag = fewer outlet changes and fewer stops.

FAQs

1) What does the Boost button actually do?

Boost activates a deeper carpet-cleaning mode on the X4 Boost. Press the button to enable it (it illuminates), press again to turn it off, and it resets when the machine is turned off.

2) Is the Automatic X4 Boost good for hard floors?

Yes—SEBO lists the Automatic X4/X4 Boost as capable of bare-floor cleaning, and the sealing strip helps reduce debris kickback on hard surfaces.

3) Do I need to adjust height when moving from carpet to hard floors?

No. The Automatic X system adjusts the brush height electronically as the floor changes.

4) Is it a good choice for pet hair?

Yes—strong brush performance for carpets plus a large bag is a big advantage for pet households.

5) What maintenance items do I replace most often?

Bags, the pre-motor microfilter, and the exhaust filter are the common consumables. Shop: SEBO Bags and SEBO Filters.
